Rawell Environemtal supply a range of products to provide solutions for the secondary containment of chemicals and hydrocarbons. Whilst the tank is always the primary containment regulations state that secondary containment is required in the form of a barrier to the passage of any leaks or spills which can restrain flow through the ground. This barrier can be in the form of concrete walls and floors but often these walls and floors are constructed from compacted earth. Where the compacted earth does not meet the required permeability the Rawmat® HDB system can be applied to provide the required level of containment. Rawell offers its Rawmat® HDB membranes combined with its Rawseal® fillets together with its drainage composites Rawdrain and slope stabilization products Rawgrid and Rawcell to provide an engineered, flexible and long-term solution.
Rawmat® HDB is an Environmental Lining membrane used to control the passage of liquids above and below ground.
Rawseal® waterstops are sodium bentonite & bitumen waterstops, replacing the need for special joint pieces, split-forming and seam welding.
