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.

What Is The Difference Between Hydroseeding and Hydromulching?

By | Admin, Information, News

Whether you are looking to revegetate cleared land on residential property, a construction site project or are preparing a mine site sustainability plan, you’ve probably heard the terms ‘hydroseeding’ and ‘hydromulching’ as you research an effective rehabilitation or revegetation strategy.

Hydroseeding and hydromulching are both efficient and effective alternatives to traditional planting processes, such as hand seeding, drill seeding and sod applications. Both methods are more economical than laying turf, they can reach rough terrain or otherwise inaccessible areas such as high grade slopes, and produce thicker, healthier vegetation that binds with the ground surface soil to effectively protect and prevent against erosion.

Although the terms ‘hydromulching’ and ‘hydroseeding’ are often used interchangeably (in practice) to describe this type of revegetation method, there are some core differences between the practical applications of hydroseeding and hydromulching:

Hydromulching - ‘Spray On Grass’

Hydromulch is a formulation of organic mulch fibres, a slurry of seeds, fertiliser, water and a binding agent known as a tackifier, which is applied to the area to be revegetated using specialised broadcasting machinery, with the media being sprayed directly onto the surface. The mulch acts as a cover for the seed, helping it to retain moisture for faster germination and growth, while protecting the soil from erosion and the seeds from washing away in a rain event. Hydromulching has proven to be very effective for the fast re-establishment and revegetation of large land areas, and commercial and constructions sites, and is especially effective on hillsides and high grade slopes, with immediate and effective erosion control and fast planting benefits.

Hydroseeding - ‘Liquid Grass Seed’

Like hydromulch, hydroseed consists of a mixture of water, seed and fertiliser which is broadcast/sprayed onto the area to be revegetated, however, unlike hydromulch, it contains no wood fibre mulch, and therefore has no capacity for erosion control. Applied the same as hydromulch, hydroseeding uses water as a carrier to spray seed and fertiliser onto the seedbed. Specially designed hydroseeding machinery allows the operator to agitate the hydroseed mixture to ensure even and constant mixing of ingredients so that the designated area is evenly covered and without sparse or patchy spots. The hydroseed mix is sprayed using hoses which makes it an effective way of distributing seed and fertiliser, especially for large or hard-to-reach areas where alternative seeding methods aren’t easily accomplished. Hydroseeding has become a popular and cost-effective alternative to traditional forms of establishing grasses and other vegetation over large areas with seed, such as broadcast and drill seeding.

Hydroseeding and Hydromulching Benefits

Hydroseeding and hydromulching are efficient and sustainable methods of rehabilitating and revegetating cleared lands on construction or mine sites, especially when compared to traditional forms of seeding.

Hydroseeding and hydromulching:

  • Quicker and easier to install than traditional seeding methods.
  • Typically cheaper than laying turf or hand seeding.
  • Retains moisture to support faster vegetation growth.
  • Minimise erosion to support strong, healthy vegetation growth.
  • Completely safe, non-toxic and environmentally friendly seeding methods.

Dry Harsh Conditions

Hydroseeding is only suitable for broadcasting grass and other seeds, but is not recommended when coverage is required in dry or harsh conditions. It is recommended that hydromulching is carried out in preference to hydroseeding alone. Hydromulching helps maintain moisture around the seed, decreasing seed mortality rates through the protective nature of the mulch, which accelerates growth and germination rates.
