Lake Liners Help Create Fresh Water Availability
Monday, October 01, 2012
Fresh water wildlife habitats are being threatened by pollution intense farming and urban development across much of the UK. As a result there is a drive to increase the number of ponds and lakes available to wildlife plus an improvement in the maintenance of existing water sources. Lake liners help with the maintenance of the water required for the healthy habitation of wildlife.
The richness of wildlife is diminishing and steps need to be put in place urgently to halt this change before we lose a big part of the UK's natural heritage. Building lakes and ponds is a practical way of protecting nature through the availability of clean, unpolluted water. Poorly managed water has a negative impact on the quality of the environment.
are used in cases where a lake or water feature is constructed as an artificial water table in locations where they would not occur naturally. In many of theses cases the soil is not suitable to hold water so the dug-out is lined.
When installing a lake liner, groundwater needs to be taken into account and if present a french drain system would need to be dug to allow water to flow laterally under the liner depositing the drainage water in a gravel slump. This drainage system will prevent the liner floating away.
The lakebed of man-made lakes needs to be prepared before laying the liner material. This is done by removing boulders and smoothing the surface as best as possible to ensure an easy liner installation process. Lake liner materials such as EPDM or Butyl are unaffected by UV rays therefore a layer of topsoil is not required, unlike PVC, which will be affected by the sun and degrade over time if not protected.
Construction, liner installation and water quality management are all critical in the the success of a lake. Imagine the consequences of swallowing and ingesting polluted water? The same would apply to aquatic creatures. Water is one of our most important natural resources.
