Landfills are a growing necessity in developing countries. Building a lining system beneath the waste body has a great role in the environmental performance of these landfills. Old landfills and contaminated ground need a cover system to ensure that precipitation does not percolate the waste and contaminate valuable ground water. Geosynthetics create a sealing system lasting long into the future to protect the ground water. Regulations exist to achieve this. We are experienced in different sealing systems as well as the whole landfilling procedure design and construction.
