Erosion Protection for Vulnerable Surfaces
Erosion of soil from embankments and channels is a serious problem. It becomes critical when the erosion results in expensive structural damage to infrastructure or when it leads to the pollution of watercourses. Relying upon vegetation growth alone is very unpredictable and unreliable as it is extremely difficult to achieve 100% vegetation coverage, leaving exposed areas vulnerable to erosion. Furthermore, vegetation can die back or become diseased, reducing the erosion control capability.
MacMat® Protection Applications
- Highway embankments
- Channel linings
- Slopes and embankments
- Railway cuttings
Turf Reinforcement Mats
Maccaferri’s MacMat® and MacMat® R are TRMs: three dimensional permanent erosion control mats composed of UV stabilized, non degradable synthetic fibers. MacMat® R has an additional structural skeleton of Maccaferri double twisted steel wire mesh within the polymer matrix.
MacMat® immediately increases the soil’s resistance to erosion by providing an environment that enhances the growth of vegetation through the mat.
Supplied in rolled form, MacMat® is anchored to the surface to be protected using staples or pins. Topsoil is brushed into the voids within the matrix. Seed can be applied to the surface before or after MacMat® is installed as vegetation will develop unhindered by the matrix.
MacMat® R is a geo-composite TRM reinforced with a double twisted mesh during the manufacturing process. MacMat® R is used on projects where the tensile strength and the shear resistance require a more preferment product. The steel mesh integrated to the polypropylene matrix is galvanized for long lasting or galvanized with PVC coating for extreme durability.
MacMat® solutions protect the soil surface by:
- Providing immediate protection of exposed areas from direct effects of wind and rainfall impact.
- Protecting seeded topsoil from washing out before vegetation has established.
- Creating an environment that enhances the growth of vegetation through the mat.
- Reinforcing the root system of plants, further binding the soil surface and increasing shear resistance of the surface.
- Reducing the velocity and volume of run-off flow by increasing water percolation into the soil.
