There is continual concern over the potential for surface and groundwater contamination from nearby landfill operations. There is further concern about the ingress of too much precipitation and stormwater inflow into landfill sites with the attendant increase in the volumes of leachate generated.

There is often too great a time lag between the implementation of the more permanent restoration works and what needs to be implemented in the immediate term by way of temporary cover works to prevent excessive leachate build up and random and uncontrolled migration of gas during the overall life of the landfill.

The benefits of thin gauge liners acting as an immediate deterrent to the activities of scavengers and the further positive features such as immediate improvements to the noxious and harmful odours and wind –blown scatter which emanate from landfill sites are important. These features, however, are secondary in nature when compared with the direct and immediate cost and time benefits which result from utilising thin liners as temporary caps which are installed during the construction cycle. These cost and time benefits are critical and are measurable savings which are linked to the guaranteed supply stream of material availability as well as to the guaranteed level of quality which is achievable from both a material manufacture and installation perspective. These MQC and CQC methods are quick to verify unlike the techniques which are associated to the sourcing and installation of natural materials such as clay and soil cover.

These temporary cap liners such as Enviro Cap are typically between 0,3mm and 0,75mm in thickness and whilst they provide immediate cost benefits to the client and are quick to install , they have to be installed by Installation specialists who possess the necessary skills in the handling and welding of thin membrane covers. Enviro Seal has accrued many years of experience in this field and would be happy to offer its specialist services to new clients.

Further cost benefits can be realised by the pre-fabrication of thin liners into larger modules which are simply unrolled or unfolded on site and the remaining in situ welding requirement is reduced to a minimum.

Typically, Linings which fall into this category can be divided , but certainly not limited to the following groups Temporary caps and covers / Landfill caps / silage covers / ash and cover protection / Hazardous and Harmful Waste segregation covers.

Enviro Seal can advise and recommend on the most cost-effective, safe and appropriate lining solutions to meet clients specific requirements.
