High-density polyethylene (HDPE) and galvanized corrugated metal (GCM) culverts Plastic conduits made of HDPE and metal ones made of GCM collect and channel runoff and storm water. They are needed on all projects. Terraquavie distributes the full range of HDPE drains and culverts and corrugated metal culverts [...]
Sediment retention fibre rolls Sediment retention fibre rolls (SRFRs) are tubular nets made of synthetic or natural materials filled with natural fibres that act as a filter. The rolls are designed to slow water flow and intercept sediment in ditches and on slopes. Products manufactured and [...]
Cofferdams and stream diversion Cofferdams and stream diversions allow work to be carried out in the dry, thereby reducing the quantity of sediment released into a body of water during work in wetland and water environments. A cofferdam is a temporary dam that deflects water into a diversion [...]
Silt fences Land-based sediment barriers (silt fences) are composed of pointed wooden stakes to which a strip of geotextile is attached with industrial staples. Terraquavie manufactures two silt fence (SF) models needed for sediment control on construction sites. The standard model is made of woven geotextile, whereas the [...]
Native seeds In projects involving naturalization or restoration of protected sites, specific seed blends are often required, or the seeds used must be for native plants. This also applies for projects in wetland environments and riparian strips or along streambanks. NATIVE SEEDS comparative chart [...]
Sod and ground-cover seeds Many projects lend themselves to revegetation with seed blends of grasses (sod) or common ground-covers. Sodding with these blends is by far the least expensive technique for revegetating large areas. The seed can be broadcast or sown mechanically or by hydroseeding. LAWN [...]
Articulated concrete mats Articulated concrete mats are a permanent erosion control system made up of mats of interconnected concrete blocks. They are flexible, allowing them to hug the contours of the ground. This solution is easy to deploy and can be used to cover [...]
Modular arch culvert The Enviro Span modular arch culvert system is a solution that allows a road to be built across a watercourse without disturbing the stream bed. Made of a viscoelastic material with a functional life of 100 years, Enviro Span non-metallic bottomless culverts are non-rusting and [...]
Temporary covers Covering ground that has been temporarily cleared during construction is an excellent way of stabilizing the soil and limiting sediment transport into bodies of water and wetlands as well as storm sewer systems and urban infrastructure. It is also a great way to preserve the dryness [...]
Ground protection mats Plastic ground protection mats optimize on-site operations by safeguarding surfaces against damage caused by circulating machinery. They avoid the costs associated with repairing these surfaces and prevent machinery from sinking where the soil is soft. Ground protection mats can be used to stabilize [...]
