How to conduct a successful Revegetation Project

By Admin, Information, News

The combination of either drought, natural erosion, heavy rainfall and bushfires across Australia often results in land that’s unable to quickly regenerate without additional help. This is where regeneration products, such as coir logs, tree guards, tree surrounds, hydroseed, hydromulch and erosion control blankets come into the picture. 

When land is devastated that is practically bare of any vegetation, it needs serious help to prevent further erosion, loss of nutrients and runoff. Helping your land regain its natural balance and return to a healthy ecosystem is a goal that can be quickly and easily achieved with the right products and know-how. So if your goal is to revegetate land that has been cleared or severely damaged, here are some processes to help revegetate your land.

Using revegetation products to re-create a healthy ecosystem

Your first step is to plan your revegetation strategy, whether you intend to grass the area or revegetate with plants and trees. Once you know your plan of action the next step is identify the correct native vegetation that flourish on your land and the environment and micro-climates that support these plants. You may already know this information, otherwise you can chat to our team at Aussie Environmental who can help. Once you have selected your vegetation to plant, your third step is to clear the land of any rubbish and weeds. You might also want to clear away most of the burnt trees and bushes. Once your land is cleared, you can then plant tube stock or give it a helping hand with hydroseed or hydromulch.

Seed regeneration: This involves stabilising the soil, preventing erosion and runoff, and giving air blown or added seeds enough time to settle, germinate and establish themselves. All of this can be achieved with a soil retention mat that can be rolled out across the ground to cover the soil and protect the seed. 

Aussie Environmental has a variety of erosion control blankets to assist with seed growth, including jute mesh, hessian cloth bolt & coir mesh.  

You can also use coir logs if you want to prevent runoff into a nearby waterway or prevent severe erosion on steep sites. 

Seed regeneration

Planting plant tube stock: Another option to revegetate your land that’s faster than natural revegetation is to plant tube stock. To help tube stock to establish, Tree Guards are recommended to protect young trees from wind damage, spray drift and foraging animals. Tree surrounds such as Jute Mat Squares are also ideal in helping to suppress the growth of weeds.

Hydroseed/Hydromulch: If you’re after some grass cover for an exposed area Aussie Environmental can spread either a standard seasonal hydroseed/hydromulch on your land or a native hydroseed/hydromulch that’s endemic to your land. These preparations include fertiliser and tackifier. We can also add growth stimulants and soil amendments to these mixes, depending on your site’s condition. These two revegetation methods are very cost effective and can be applied very quickly to large areas of land.

As revegetation contractors and CPESC (Certified Professional Erosion & Sediment Control) Accreditation, Aussie Environmental can help you to find the right solution for your land. With years of experience in the industry, we can give you a number of different options to revegetate your land, ensuring that you have all the information you need to make the best decision for your land.

dust control

Top 5 dust control strategies preferred by environmental consulting companies

By Admin, Information, News

Australian environmental consulting companies are often called in to help control dust on both private land and construction sites. If you can foresee dust problems at your project’s site or are already experiencing issues on your land, it’s best to attack the problem head-on, before it gets out of hand. So here are five of the best dust control strategies preferred by environmental consulting companies for either construction sites or private land. 

1. Revegetate the land

The most environmentally friendly long term solution for controlling the loss of topsoil as airborne dust is to revegetate the area with native plants. This is a strategy that might be applicable to large privately owned land or towards the end of a construction project, as part of the landscaping. Re-planting barren areas is an extremely effective dust control strategy, as the native plants, bushes and trees not only cover the exposed soil and reduce the wind factor, but their roots help to bind the soil together.

2. Adding Dust Suppression Soil Binder Polymer coatings

Dust Suppression Soil Binder is a method that works well for construction sites that need a temporary application that lasts for the length of their project. For large areas it’s an inexpensive method that can be applied quickly to exposed soil, working almost immediately to reduce dust for construction sites, stockpiles, dirt roads, construction/hall roads, and large exposed areas caused by urban sprawl. Quality Soil Binder typically lasts 6-12 months depending on the dilution and can be reapplied if needed. 

3. Hydromulch

Hydromulching is another immediate, effective, economical revegetation strategy for large areas of exposed soil from construction and mining activity; whether the area is flat, hard to access or significantly steep. Hydromulch is a fibre-mulch mixture of seed, fertiliser, tackifier and water that is sprayed on exposed areas to generate grass growth. Significantly cheaper than laying turf for large areas, and although a higher cost than Soil Binder initially, Hydromulch provides a long term cover and does not need to be reapplied.  

The mulch acts as a cover for the seed, helping it retain moisture for faster germination, while protecting the soil from erosion and the seeds from washing away in the rain. The mulch also consists of soil builders and growth stimulants which act to replenish the topsoil with much needed nutrients and improve the soils ability to support long term growth, all while promoting erosion control methods and soil stabilisation.

4. Cover exposed soil with Geofabric or Erosion Control Blanket

Another option to reduce dust on site is to temporarily cover areas of exposed soil with Geofabric or a biodegradable erosion control blanket. Geofabric is commonly used to temporarily cover exposed areas and loose soil stockpiles on construction sites. It is then peeled back and disposed of once the cover is no longer required. A more environmentally friendly option with less carbon footprint, is to use biodegradable erosion control blanket such as Hessian Cloth that does not need to be removed and thrown out; the blanket can be left to biodegrade naturally. 

5. Integrated Construction Management

The best approach for dust control on any construction project is to have an Integrated Construction Management Approach. It is recommended to consult with an Environmental Scientist/ Certified Professional Erosion and Sediment Control (CPESC) expert to implement an erosion and sediment control plan to prepare for all weather conditions, whether it be wet, dry and windy. It is important all workers on-site are well informed and follow protocol procedures (for example driving slowly on dirt roads to minimise dust). Therefore effective communication is required on all levels to ensure any soil stabilisation issues that arise are identified and reported, so the correct erosion control method or product can be applied. Ideally, management should also ensure proper machinery and materials are on-site, such as water trucks that can suppress dust and apply soil binder if needed, along with erosion control blankets.

How to install a silt fence effectively

By Admin, Information, News

Silt fences (or sediment fences) are installed to help control sediment and rill erosion within exposed soil on construction sites by providing a temporary sediment barrier. Silt fences are designed to prevent dirty water from washing into our local waterways during rain events. A single building site can lose truckloads of soil in one storm event.

It is therefore critical, Silt fences are installed correctly to ensure they effectively capture sediment and protect the water quality of our local streams and waterways. To do this, there are a few things to consider. 

Silt fence material

Silt fence material is a permeable geotextile fabric that helps capture sediment and slow down the water flow. To work effectively under the strain caused by rain events, it is important the silt fence material is extremely strong and durable. Aussie Environmental provides two geotextile options for different applications, Woven Polypropylene geotextile & a natural biodegradable Jute geotextile.

siltfence

UV Stabilised Woven Polypropylene

Polypropylene, which is also known as PP for short name, is a thermoplastic resin material that is produced by the polymerization of propylene which is woven into strips/threads to create a light, but strong and heavy duty material. Due to the materials strength and light-weight it is the most commonly used Geotextile material for Silt Fencing. 

Aussie Environmental’s polypropylene is UV stabilised and made from 100% virgin PP granules.

EcoFence Jute Geotextile

Aussie Environmental’s EcoFence is a more eco-friendly alternative to plastic (polypropylene) silt fence. Made from 100% biodegradable Jute Geotextile, EcoFence material is ideal for riparian zones and floodplain areas where once installed, it can be left in the environment to naturally break down over time.

Optimal posts for silt fence material

The best type of posts to hold up and secure the geotextile material is hardwood 900mmx 50mm x 25mm timber stakes. There are other types of posts on the market, but at Aussie Environmental, we have found that hardwood timber posts work the best. Timber posts have large cross-sectional areas to resist side loads and the material can be attached securely using wide staples. We have often seen zip or wire ties used, but these aren’t as effective as staples. For most soils, hardwood timber posts are the posts of choice, because they are long lasting and help to secure the silt fence in high winds.

Optimal spacing of the posts

To ensure that these sediment fences work correctly and meet best practice, the posts need to be spaced at a maximum 2 meters apart. If the stakes are spaced any further apart the fence is at risk of becoming compromised; with the runoff finding spaces underneath the fence and eroding the soil. For high flow areas, closer spacing of timber stakes is recommended to secure the fence. The additional cost of a few extra posts is off-set by the knowledge that your fence will withstand higher flows and strong winds and not need any repairing.

Optimal height of the posts

In general, the height of the posts needs to be at least 40cm longer than the geotextile material, as this allows 40cm of the post to be driven into the ground, making it very secure. For silt fence installation, Aussie Environmental has 900mm hardwood timber fence posts that are tailored to suit the height required for the silt fence material to work effectively and for the posts to be stable in the ground. 

Silt Fence positioning

Silt fences should be installed on a site before soil disturbance (earth moving) begins, down-slope from the construction area or stockpile. They should always be installed along the contour of the slope you are protecting considering the likely runoff volume (catchment area). 

If installing a silt fence on a downward slope you should be constructing “silt fence returns” or “j’s”, positioned perpendicular to the silt fence.

Solutions For Site Rehab And Erosion Control

By Admin, Information, News

Revegetating damaged landscapes from building, excavation or mining projects can be difficult in Australia’s diverse environment. A range of soils, site and tumultuous weather conditions across the country means that there isn’t an ‘all round’ revegetation solution for every site’s rehabilitation and erosion control project.

However, there are some widely recognised methods as the most efficient, environmentally friendly and cost-effective solutions for long lasting, healthy revegetation in Australia’s ranging habitat.

Hydromulching

Hydromulching is a fast, effective, economical revegetation strategy for large areas of exposed soil from construction and mining activity; whether the area is flat, hard to access or significantly steep. Hydromulch is a fibre-mulch to the mixture of seed, fertiliser, tackifer and water that is sprayed to exposed areas to generate grass growth. The mulch acts as a cover for the seed, helping it retain moisture for faster germination, while protecting the soil from erosion and the seeds from washing away in the rain. The mulch also consists of soil builders and growth stimulants which act to replenish the topsoil with much needed nutrients and improve the soils ability to support long term growth, all while promoting erosion control methods and soil stabilisation.

The seeding process involves specially designed hydromulching equipment to spray a slurry of water, seed, fertiliser, organic mulch fibres and a binder/tackifier onto the seedbed. A specialised hydromulch machine agitates the hydromulch mixture during application to ensure an even and constant distribution. This results in a more even application of the mix which protects the soil surface from erosion and also promotes faster, more unified seed germination for grass growth.

Hydromulching is an effective solution for erosion control methods and stabilisation of road side batters, soil stockpiles, long term dust suppression, mine site rehabilitation and remediation of large industrial areas. It is recommended to conduct an on-site soil analysis to best determine the custom blend of ingredients that will give your site the best chance of revegetation success. Determining which plant growth medium products best suit your site’s conditions and meet your project’s requirements is essential to their efficacy and sustainability.

 

Erosion Control Blankets

In land development, erosion control methods is important. Aside from preventing water pollution due to runoff and the potential habitat loss of nearby ecosystems, erosion control also staves off soil loss and consequently, property loss. In urban areas, erosion control techniques are primarily concerned with storm-water runoff management, however soil loss due to winds and sloped properties must be considered as well.

As a landscaping solution, Erosion Control Blankets help provide soil erosion protection and assist in the establishment of vegetation to help protect slopes, or low-flow channel applications and drainage areas.

Jute Mesh, Jute Matting, Coir Mesh and Coir Blankets are all biodegradable blankets that are installed to protect exposed areas from water and wind whilst vegetation is re-established.

Open weave blankets such as Jute Mesh and Coir Mesh are most commonly used in bioretention basins and swale drains, pinned over a layer of mulch to protect plants and help the vegetation re-establish. Whilst Jute Matting & Coir Blankets are blankets commonly used on exposed batters and slopes to provide a form of erosion control protection and weed suppression to disturbed soil, until vegetation takes hold.

 

Coir Logs

Coir Logs are another biodegradable erosion control product that is ideal for stabilising hills, banks, shorelines, and other erosion prone areas. Easy to install, coir logs create a natural control area that helps manage stream flow velocity and prevent scouring and soil loss on slopes and in gullies. Coir logs are commonly used in open drains found along roads where they are used to capture sediments and slow water runoff. They are also used to stabilise shorelines and embankments whilst providing a natural wall of protection for plants and soil.

4 Reasons Why Correctly Installed Silt Fences are Important

By Admin, Information, News

In Australia, compliant silt fence, sediment and erosion control products are important for all parts of construction, landscaping and excavation projects.

Correctly installed Silt Fences, also known as Sediment Fences, are critical in preventing onsite and offsite erosion, protecting our environment & local waterways, pertaining to council regulations, and maintaining building integrity amongst the community.

silt fencing

1. Prevent Stormwater Pollution

Soil erosion from building, development, excavation and construction sites is a major source of stormwater pollution. When it enters our waterways, sediment (such as soil, sand, silt, mud) and litter washed from urban areas can cause major short & long-term environmental problems. A single building site can lose up to four truckloads of soil in one rain storm. Sediment washed from building sites into gutters and stormwater drains can clog up streams full of silt, cause flooding and affect water quality and fish stocks in our creeks, rivers and coastal waters. Stormwater flowing untreated into our waterways that provide vital habitats for animals and plants.

Correct installation of quality silt fence, helps prevent silt, soil and other debris from construction sites running into our local streams & waterways in a rain event, protecting our local environment from such pollution.

  

2. Abide to Council Regulations, Avoid Costly Fines

Because of the effect stormwater pollution has on our environment, local councils & government bodies strictly regulate construction & building sites to ensure they meet environment regulations to help protect our local waterways. Failing to install compliant erosion control measures can be a costly exercise and result in on the spot fines and sanctions from government bodies & local councils. Fines can exceed up to $10,000 – especially for repeat offenses.

3. Prevent On-Site Erosion

By correctly putting preventative erosion control measures in place before a rainfall event, this can protect a worksite project from costly erosion damage. Major erosion damage can easily occur when there is a severe storm, torrential rain, flash flooding or just a quick downfall of rain; all such weather events that happen regularly in parts of Australia, especially in South East Queensland.

  

4. Integrity of your Site Works

As part of the construction industry it is vital to abide by laws and regulations for obvious legal reasons, but ethically it is just as important to do so, in order to keep an upstanding reputation amongst the community.

Work sites are typically exposed to the general public, and a site seen to be polluting the local environment can have drastic negative consequences to a business’ reputation; and terrible repercussions to the overall business. All it takes is one bad photo shared on social media or a quick complaint to the council to expose a company and create major backlash. On the flip-side, a company shown to be proactive in environmental and erosion control measures helps promote a strong public image, with an overall care for the local environment and community.

  

Quality – Not All Fences Are Equal

Quality of the silt fence material is important, as is correct installation. Unfortunately, not all silt fencing materials are the same quality, with some cheaply made silt fence material not UV stabilised, causing it to deteriorate quickly when exposed to direct sunlight. Also, if the fibre fabric material is too thin, it does not have the strength to stop the flow of contaminated water, and again fall apart quickly. When having sediment control measures such as silt fence installed – it needs to last the time required. Aussie Environmental’s silt fencing rolls are of the highest quality, UV stabilised woven material with heavy duty 100gsm thickness for added strength, to ensure it lasts the test of time.

Silt Fence Installation Techniques

By Information, News

Aussie Environmental install their silt fence using the trench-less or static slicing technique.

So What Is The Static Slicing Technique And How Does It Work?

Static slicing can be described as the insertion of a narrow custom-shaped blade at least 200mm into the ground, and simultaneously inserting the silt fence fabric into the opening (10mm wide) created by the blade being pulled through the ground.

Slicing technique
Slicing technique2
Slicing technique3

What are the benefits of static slicing (trench-less) silt fence technique vs the standard trenching technique?

The static slicing method can be installed 2 to 4 times faster than the trenching method, this saves construction and civil sites time, money and labour.

Static slicing installation can hold more water or runoff and has less seepage than a standard trenched silt fence during unforeseen rain events, this means the silt fence will perform better in the long run and need less maintenance overall.

Using machinery (Slicing) rather than man power (trenching) is more accurate and consistent, making it easier to follow compliance’s and also produces less mistakes during the installation process.

Additionally, the sliced method of installation generally provides a stronger, higher performing and longer lasting silt fence.

Is your installed silt fence compliant?

If you do not install your silt fence to correct compliance’s you or your site developer are at risk of fines for non-compliance.

A professionally installed silt fence should always be installed to specifications; therefore, you can rest ashore that upon installation of an Aussie Environmental silt fence will be fully compliant.

Regular inspection and maintenance

Regular inspection and maintenance is also required to keep your site compliance. A Silt fence should be checked weekly and also after rain events. Check to see If there is any damage to the silt fence including broken stakes, torn fabric, holes and even if there are gaps between fabric and the ground.

If you see any of these issues the silt fence should be replaced or repaired immediately to avoid non-compliance.

Silt fence should be checked weekly and also after rain events for damage

Professional sliced installation VS do it yourself trenching

Let’s break down it down.

Professional static slicing 

  • Installation efficiency
  • On average slicing installation technique is 2-4 times faster than trenching.
  • Professional installation makes it easier to follow compliances and standards
  • Sliced method generally has Less seepage than a standard installed trenched silt fence
  • Better overall long-term performance than a standard installed trenched silt fence
  • More accurate and consistent
  • Can be installed on steep slopes

Do it yourself trenching

  • You need to ensure that the fabric is entrenched consistently throughout the whole installation, one gap can make the fence non-compliant
  • Can take a lot longer if you don’t have the right machinery or if you are doing it by hand
  • Ideal for small jobs under 50m
  • Must be trenched-in and backfilled correctly
  • Trench must be around 200mm deep by 200mm wide
  • Significant manual labour for long runs which can cost more money in the long run
  • Soil compaction can take considerably longer to provide a quality long life silt fence

Quality products - Not all installers use the best products

Using poor quality products can cause your site to become non-compliance.

By using a high-quality silt fence material will help guarantee your silt fence will last the required length of time on site.

Aussie Environmental only Sell heavy duty 100gsm UV stabilised silt fence that is Certified by AASHTO (American association of State Highways & Transportation Organisation) and has a 2-year life expectancy.

In addition, our silt fence is also ISO 9001 Certified making sure our silt fence material is manufacturer to the highest quality standards.

When should you not use silt fence?

Silt fences are only to be installed for sheet flows and should not to be installed in areas of concentrated flows, check dams or across watercourses.

Consideration of specific site requirements and other erosion control measures may be a better alternative, such as our heavy-duty silt fence installation or our coir logs products.
