Walo UK Limited are specialists in the field of Hydraulic Asphalt Engineering supplying Impermeable Lining Systems for the permanent sealing of Landfill Sites, Dams, Reservoirs, Canals, Sea Defences and Contaminated Land.
Our Dense Asphaltic Concrete (DAC)lining system is a 'specifically designed stand-alone impermeable lining' for the bottom and side slope sealing of containment sites, designed to greatly improve on the basic 'EU Landfill Directive' conditions for permanently preventing pollution to soil and groundwater.
DAC is flexible and extremely strong, manufactured locally and engineered on site under specific CQA procedures.
The DAC barrier is generally engineered to a thickness of 14cm and to a coefficient of permeability better than 1 x 10-13 m/s (metres per second).
The DAC lining system contains no mobile toxic compounds and is unaffected by all natural weather conditions.
DAC is so strong it can be trafficked by rubber tyred vehicles without fear of damage. It can be laid on slopes up to 1:1.5 (34 degrees).
The DAC impermeable lining system is resistant to any form of chemical attack and is unaffected by temperatures of 6
