In addition to lining dam faces and cores, reservoirs, canals and landfill sites, Dense Asphaltic Concrete (DAC) is a very versatile product, useful in all kinds of containment lining systems where an impermeable barrier is needed.

WALO is at the forefront of technological advances in hydraulic technology, which has seen DAC being used for sealing sea defences, coastal groins, irrigation systems, river banks and even for creating snow reservoirs in ski resorts for the production of artificial snow.
