Landfill Lining

The Dense Asphaltic Concrete
impermeable landfill barrier system laid by WALO is a ”Fully Engineered Specific
Barrier System” which does not have to rely on it being laid 50cm thick to make it
impermeable and strong enough to withstand decades of service.
The DAC barrier is designed to be completely impermeable to methane and leachate
found in most solid waste landfill deposits.
Due to its high density, dense asphaltic concrete is extremely resistant to
chemical attack, it is strong and yet flexible having a total thickness of only
34cm.
DAC is very stable on slopes up to 1:1.5 (340) providing more void space
for the waste product and ensuring a perfect barrier against leakage to the
environment.
