"Straw based hydromulches now approved for use on TMR revegetation projects"
Earth works & the stock-piling of our topsoils destroys the delicate biological system, & disrupts the natural balance of our soils. This has made them less responsive to conventional fertilisers & revegetation techniques. It has never been easy to grow grass on our degraded soils, in Australia's punishing climate.
It's time to change the way we revegetate our sites.
Revegetation and rehabilitation projects are large scale and costly exercises. Problem is, whether it's because of poor implementation or inferior product spec'ing, re-work is far too common and results in costly delays. And budget blowouts, bad publicity and expensive fines don't go down well in the boardroom, nor do they sit well with clients or the EPA.
No More Spray and Pray
In 2012, EnviroStraw made a commitment to research, design and manufacture environmentally responsible revegetation products and systems. Our raw materials are composed of 100% Australian renewable resources and have been tested in Australia's widely varied and tough environments. The research and development of our innovative, world class soil rehabilitation products is an indicator of how seriously we take our social and environmental responsibilities. In a short period of time, EnviroStraw has made a difference on mine and development sites around Australia. Our efforts have been recognised with awards from the IECA, and a rapidly growing portfolio of success stories on some of Australia's most formidable revegetation projects.
These are the Facts
According to the National Oceanic and Atmospheric Administration, 80% of ocean pollution begins on land with runoff from soil loss and agricultural fertilisers and pesticides (amongst other pollutants). When we consider the damage these practices cause to our oceans and waterways, it is not difficult to see how important it is we take responsibility and re vegetate our construction sites correctly to stop erosion and soil loss into our delegate ecosystems.
When we consider the damage these products do to our oceans and waterways, it is not difficult to see how destructive they are to our soils.
Acid based non organic fertilisers require regular reapplication, as they focus on feeding the plants and not rebuilding the overall soil health. This is difficult (if not impossible), to do on a civil construction site. In the medium to longer term, they actually damage the soil life. Earth works also destroy the soil life by disturbing it. When that soil is stock piled, the overall soil health is fundamentally damaged. On most projects, it is almost impossible to maintain the site long term. We see evidence of this on failed revegetation projects all around the country. Instead, we need to first rebuild soil health so that it becomes a long term, self sustaining ecological system.
EnviroStraw HGM Products are Designed to Enhance Vegetative Cover on any Construction Site
The design of the EnviroStraw product range has been carefully researched and trialled. These are products which are environmentally responsible, eliminating the need for chemical input fertilisers. EnviroStraw products are scientifically balanced, ensuring nutrients are not over supplied and available to leach into our waterways. Importantly, EnviroStraw products are extremely cost effective to implement, and are native grass friendly.
In 2015, the EnviroStraw range of HGM products was recognised at the prestigious IECA Innovation Awards. Our award winning HGM products have been designed by science, are biologically activated, and 100% safe for our environment. Our extensive research and development program has clearly shown that the key to a successful rehabilitation project is in the soil. If we successfully bring the soil back to life, it has the ability to become self sustaining.
Why do we Need to Change?
On a typical rehabilitation project we see these results: Firstly, a good strike of the cover crop (millet or rye depending on the time of the year). We then see these grasses yellowing and dying within 2-3 months (Nitrogen draw down and shallow rooting are part of the problem). This process leaves large sections of exposed ground. In response, weeds establish and two to three years later we may (or may not) observe the establishment of native grasses.
So why does this happen?
It is caused by what is commonly known as the 'industrial agricultural practices syndrome'. The important point is that revegetation processes and objectives are entirely different to farming. Once the cover crop is gone, weeds will naturally establish because it is their job to fix the imbalances in the soil. After they have performed that task (a process that can take up to five years), the weeds die and native grasses can possibly establish.There is a better way, and it is scientifically proven to work.
No other Hydromulch works like the EnviroStraws range of Hydraulic Growth Mediums (HGMs). The EnviroStraw range of Hydraulic Growth Mediums (HGM) have the following benefits:
Products Designed by Science to Solve a Range of Problems
EnviroStraw Plus: This is not just a Hydromulch, but a true Hydraulic Growth Medium (HGM). It includes our biologically activated, highly mineralised soil conditioner. An HGM without the binder, EnviroStraw Plus allows the application contractor to add the tackifier at the time of mixing and spraying. EnviroStraw Plus can be used for any hydromulch project.
EnviroStraw BFM: This innovative product has the same ingredients and delivers the same benefits as the EnviroStraw Plus, but includes hydrocolloid cross linked binder's. This product can be used successfully on steeper slopes of 3-1 & above. It is an HGM and bonded fibre matrix that includes a chemically-engineered soil stabilise and tackifier that provides a superior bond to the soil particles and mulch fibres. There is no need to blend tackifiers on the application machinery.
EnviroMatrix: Soon to be released, this is EnviroStraw's solution to replace topsoil using Australia's most advanced science. EnviroMatrix will be used where topsoil is in short supply, or has very low organic carbon levels. It replaces topsoil and is designed for the most challenging of sites. EnviroMatrix is a scientifically designed product with added minerals, biologically activated organic fertiliser, Biochar, and more than 30 carefully selected microbes. Binders are included.
Working with Nature, Embracing Science
Our premium range of Hydraulic Growth Medium (HGM) products are designed to establish long term vegetation by rebuilding the soil the way mother nature intended, only faster, with a little help from science whilst utilising cutting edge scientific techniques.

It's Not Just What You Put on the Soil. It's What You Put in the Soil.
EnviroStraw HGM products are unique and have many benefits over conventional Hydromulches:
Soil Science ... Left: How's that for binding power? Right: EnviroStraw HGM products encourage growth-boosting Humus in the soil ... The fibres are designed to hold moisture and support faster vegetation growth and thus minimise erosion.
Products designed to solve a range of problems:
For Flexibility & Strong Growth: EnviroStraw Plus. An HGM without the binder, allowing the application contractor to add the tackifier at the time of mixing and spraying.
For Slopes 3-1 & Below: EnviroStraw BFM. An HGM and Bonded fibre matrix that includes: a chemically-engineered soil stabiliser; tackifier that provides a superior bond of the soil particles; and mulch fibres. No need to blend tackifiers on the application machinery. Used on slopes 3-1 and below.
For Difficult Slopes & Improved vegetation: EnviroStraw HGM Plus. An HGM, FGM and BFM with added fibres for increased stability on the most difficult slopes, with added VAM mycorrhiza fungi for improved vegetation establishment drought resistance and overall plant health.
