The life extension of any aquatic resource such as a lake is dependent on maintaining adequate water levels. There are a number of reasons that a lake can experience water depletion. This includes normal evaporation and a decrease in natural water replenishment (i.e. rain fall). However, the primary cause of water loss is ground absorption. Essentially, due to unsuitable ground conditions, water from a lake can leak back into the ground. Not only does this loss decrease the visual appeal of the lake, but it also can cause significant harm to the surrounding environment; especially wildlife. Equally problematic is the contamination of a lake from ground pollutants. These are pollutants that may have already existed prior to the lake being created if it is a manmade edifice and/or contaminants that may originate from other sources that have managed to circumvent natural barriers.
Enviroseal’s lake liners can be employed to effectively combat these problems. Our lake liners are created out of a synthetic geomembrane. This is a material that is made up of innumerable small membranes that are impermeable. Together, these membranes form a hydraulic barrier that prevents liquid substances from passing through it. As such, once properly installed, water cannot escape from it and liquid based ground pollutants cannot enter through it. For application in lakes, Enviroseal utilizes two types of geomembrane materials for lake liners: High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE).
The choice of polyethylene based materials is significant. Polyethylene offers a number of useful characteristics that make it particularly ideal for sub-surface utilization. With considerable tensile strength, our polyethylene lake liners are significantly resistant to puncturing from the type of debris that is typically found on lake sub-surfaces. Further, our polyethylene lake liners are resistant to temperature fluctuations; both hot and cold. The ability to withstand the various types of inclement weather conditions of the seasons allows for year-long protection. Equally, the material is eco-friendly and poses no threat to humans, wildlife or surrounding environment.
