Many construction activities
result in disturbed or bare ground that is vulnerable to weather
erosion (e.g. building areas, haul roads, spoil heaps and
quarries). The consequential silt laden stormwater run-off,
plus site debris, often contaminates surrounding land, watercourses,
lakes and drains - resulting in significant environmental
pollution and potentially costly fines.
However, due to the on-going nature of construction
works, it is generally not possible to protect exposed surfaces
until the project is complete. So stormwater from such sites
remains one of the largest unaddressed non-point sources of
water pollution in the UK.
But, with the introduction of Hy-Tex Terrastop™
Premium silt fence, there is now a practical, economic and
effective method to reduce run-off pollution.
The Solution
Terrastop™ Premium is a special, high
quality, permeable, technical filter fabric that can be installed
as an entrenched vertical perimeter barrier fence, and is designed
to intercept and detain run-off, trapping harmful silt through
settlement and filtration before it leaves the site.
Although the benefits of silt fences have yet
to be widely utilised in Britain, the concept is not new.
Silt fences have been used extensively in other countries
for many years, and their proven performance (Intercepting
up to 86% of suspended solids [Horner et al. 1990]) has made
them a standard Best Management Practice on a diverse range
construction projects, while in-depth research and practical
experience has identified the most important characteristics
for effective results.
Key Features
Based on this invaluable knowledge, Hy-Tex
Terrastop™ Premium has been designed to exceed the highest
standards, incorporates many unique features, and is also "CE
Mark" certified for erosion control applications in accordance
with new mandatory European requirements.
