The largest threat to wetlands is the risk of being flooded with sediment as a result of a poorly managed construction site. Most construction projects require erosion control to prevent damage to the wetlands.

Tidal fluctuations and wave action can cause major damage to coastlines and off-shore construction projects. Nonwoven and specialty woven geotextiles can be used as a filter under layer beneath stone/ rock armour. Also riprap or synthetic erosion control mats are used to control erosion by disallowing the sub grade soil particles to erode. The geotextiles prevent erosion carried off by runoff water or other erosive waters, such as waves, stream flow, etc.

Design high-performing, ‘low environmental impact’ GEOWEB channels for stormwater conveyance, as well as for erosion protection of containment facilities. Protect impervious liners in lagoons and detention basins, preventing degradation and contaminant leakage. With the GEOWEB system, channel and basin designs can be customized for each project with vegetation, aggregate or concrete infill, offering more economical solutions than rip-rap, gabions or reinforced concrete systems. The GEOWEB system’s high-density polyethylene (HDPE) material is highly resistant to acids and bases so is ideally suited to withstand harsh chemical environments.
