Hydromulching for Erosion Control
19 February 2018
Profile Products LLC is the world’s pre-eminent manufacturer and supplier of hydraulically applied erosion control technologies, turf establishment blankets, turf reinforcement mats, and vegetation establishment products.
Hydraulically applied erosion control is fast becoming the preferred solution to control surface soil run off, specified in preference to erosion blankets. Unlike blankets, hydraulically applied erosion control systems are sprayed on and therefore genuinely follow the contours of the ground, with no bridging, air pockets or potential for washout below the matting. Conventional coir blankets and jute netting can allow water to seep through and gradually cause washout behind the matting.
These spray-on systems actually lock the soil particles together using soil binders and biodegradable fibres to create a seamless blanket of protection. Hydraulically applied erosion control systems have been proven to reduce soil loss by > 99 per cent (a cover factor of < 0.01). These products are applied at thicknesses ranging from 3400kg/Ha to 5000kg/Ha depending on the severity of slope and soil conditions.
Flexterra® HP-FGM™ delivers a nearly perfect balance between three fundamental pillars of performance — erosion control effectiveness, growth establishment and functional longevity — to create the highest performing hydraulically applied medium on the market today. Typical applications would be:
- Flood Defense Schemes
- Coastal Erosion
- Steep Embankments
- Infrastructural Projects
Why incur the cost of smoothing your slopes for erosion control blankets that are prone to bridging and voiding? Experts recognise that rough seedbeds demonstrate lower erosion potential and their undulations retain seed and moisture for growth.
With Flexterra® HP-FGM™, fine grading and extensive soil preparation are unnecessary, allowing you to apply the product for immediate protection and superior performance at reduced overall costs. Flexterra® HP-FGM™can be applied quickly — even under wet conditions — using less labour and minimising safety and access concerns. Get the job done and move on to the next one with fewer rainouts.
As the world’s most effective Green Design Engineering™ alternative to hard armor, the GreenArmor™ System offers a more aesthetically pleasing and environmentally superior means of protecting stormwater channels, waterways and steep slopes. The system brings together the most technologically advanced erosion control and revegetation products to provide:
- 30 to 50 per cent less cost than hard armor
- Twice the erosion resistance of natural vegetation
- Higher-density turf
- Unmatched factors of safety
Today, the fully vegetated GreenArmor™ System raises the limits of vegetation to water velocities of over 9m/sec.
Soils and substrates associated with denuded sites from construction, mining, energy development and other land disturbing activities are inherently lacking in organic matter, nutrients and biological activity essential to sustainable vegetative establishment.
Ideally these sites would be covered with several inches (centimeters) of rich fertile topsoil to help develop a reasonable growing medium. However, there is simply not enough suitable or reasonably priced topsoil to ameliorate inhospitable conditions on every site.
ProGanics™ Biotic Soil Media™ (BSM™) has been designed as a topsoil alternative that accelerates the development of depleted soils/substrates with low organic matter, low nutrient levels and limited biological activity. ProGanics is not a direct replacement for expensive topsoil, but provides an abundant source of organic matter and soil building components to quickly modify soil chemistry, initiate growth establishment and buildup of the uppermost ‘O’ and ‘A’ soil horizons.
