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 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 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 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.

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 fence 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 fence 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.

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.

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.

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.
