WALO’s Dense Asphaltic Concrete (DAC) lining system provides a strong, flexible, non-toxic lining, which is thin enough to flex under extreme pressure without cracking, while being totally safe for human, animal and marine life. These factors make it perfect for water storage.
WALO has created a Dense Asphaltic Concrete (DAC) impermeable landfill barrier system which is impermeable to methane and leachate found in most solid waste landfill deposits.
WALO provides hydraulic asphalt concrete impermeable barrier systems to the water and power industries, lining dams of any size.
For over 50 years Dense Asphaltic Concrete (DAC) has been successfully used as a specialist method of constructing an impermeable central core liner to seal large embankment dams.
WALO is at the forefront of technological advances in hydraulic technology, which has seen DAC also being used for sealing sea defences, coastal groynes and river banks.
