Due to a large body of research and practical experience, the placement of ballast layers on top of a primary geomembrane barrier has internationally become common practice.
Field Research presented by Msiza and Shamrock (2014)*1 clearly shows a reduction in the mechanical and performance properties of exposed geomembranes. Through eliminating UV and thermal exposure of geomembranes, the depletion of anti-oxidants out of geomembranes is slowed significantly, thereby extending the expected service life of the geomembrane (Rowe et al, 2013) *2.
Large volumes of construction traffic are required to construct traditional ballast layers. It is a known fact that up to 80% of all primary barrier damage occurs during the placement of covers over geomembranes. Additionally, through the importation of soil or the placement of concrete, valuable storage colume is lost.
SoilTain Protect is an innovative geotextile containment system manufactured utilizing state-of-the-art weaving technology, which provides a tubular system interconnected into a singular geosynthetic mattress configuration. SoilTain Protect must be utilized wherever it is required to avoid solar and UV exposure on geomembranes.
