Erosion Control Matters Very often, construction can mean removing vegetation, altering the landscape and/or covering previously vegetated areas with roads, driveways or buildings. These changes often cause soil erosion and sediment deposits, which can lead to a multitude of problems. ENVIRONMENTAL AND ECONOMIC CONSIDERATIONS ˴˴ Disrupting the ecosystem can hinder the natural resources on which wildlife depend for survival ˴˴ Storm water runoff can increase stream bank erosion and disturb aquatic habitats and lifecycles ˴˴ Construction site soils and chemicals can wash into water supplies and...

Tensar® VMax® products will provide permanent vegetative reinforcement, allowing the area to look natural and green but with an engineered solution that will withstand bankfull flood events. A greener and more cost-effective bioengineering solution can provide underlying engineering stability whilst improving the visual landscape. RollMax™ Rolled Erosion Control Every site has unique challenges created by soil characteristics, topography, climate and other environmental conditions. Tensar can cover them all, with our family of RollMax™ Rolled Erosion Control Products (RECPs). Whether you need...

Erosion Control Blankets Erosion Control Blankets (ECBs) immediately prevent erosion and help vegetation get established. As vegetation root and stem systems stabilise the underlying soil, most ECBs gradually degrade. These products come in a range of weights and materials to accommodate low- to high-flow channels and moderate to severe slopes. ˴˴ EroNet™ Short-Term Photodegradable ECBs are designed for moderate slopes and low-flow channels. Made of 100% agricultural straw stitched to or between lightweight polypropylene netting with degradable thread, EroNet ECBs come in short-term varieties...

Slope erosion protection on the M25 Motorway, UK. HydraMax™ Hydraulic Erosion Control Hydraulic Erosion Control Products (HECPs) prevent erosion and aid vegetation establishment on slopes. Tensar’s HydraMax™ Systems apply seed, soil amendments and hydraulic mulch in one step, offering a low-cost, low-labour solution. All HydraMax Systems’ products are made with our patented proprietary blend of straw, reclaimed cotton plant material and tackifiers to ease application, enhance adhesion, retain moisture and stabilise soil. HydraMax HECPs also: ˴˴ Consist of a porous matrix with strong soil adhesion...

Spraying HydraCX™ through rock netting on a soil nailed embankment for a rail project, UK. Standard Performance HECPs HydraMax™ standard HECPs for mild to moderate slopes are excellent alternatives to wood and/or paper mulch and blown straw, which may take two steps to apply. ˴˴ HydraGT™ Moderate Slope Mulch Blend with Tack is ideal for short slopes with up to 2:1 gradients ˴˴ HydraGS™ Mild Slope Mulch Blend works best on short slopes with up to 3:1 gradients Slope Conditions Application Rate HydraCX™ Extreme Slope Matrix (metric only) =1H:1V 3,400 kg/ha HydraCM™ Steep Slope Matrix (metric only)...

RevetMax™ Flexible Revetment Flexible revetment mats provide cost-effective erosion protection from turbulent water flow and moderate wave attack. Tensar’s patent-pending RevetMax™ Systems can be ideal for applications where riprap, articulated concrete blocks or other rigid materials are normally used. When combined with a Tensar® Turf Reinforcement Mat (TRM) or other underlayment, this unique armouring solution dramatically elevates permissible shear stress and velocity protection. Satisfied customers have also found that RevetMax Systems: ˴˴ Are highly flexible and install easily over difficult...

SediMax™ Sediment Retention Unprotected topsoil, particularly on slopes and construction sites, is vulnerable to erosion and runoff problems. Significant damage can occur until these areas are ready for permanent erosion control. Tensar’s SediMax™ Systems can prevent much of the damage and save millions spent on restoring slopes, rebuilding drainage channels and dredging ponds and streams. Sedimax-Fr™ Filtration Rolls SediMax-FR™ (Filtration Rolls) create a temporary, threedimensional sediment filtration structure perfect for forest fire rehabilitation, bioengineering projects, construction sites,...
