Wick Vapour Drain is usually installed between the subgrade and the liner and channels any vapour and gas build up from the floor of the pond through the slopes and out the top vent tubes. This eliminates any gas build up underneath the liner that can potentially cause damage to the liner. Titan’s Wick Vapour Drain is installed in a 4-8 meter grid pattern along the floor and slopes. It then leads to a 3 – 4″ perforated pipe that in turn is connected to a vent pipe on the outside of the lagoon.

Wick Vapour Drain can also be installed between the liner and a concrete slab sub-grade, with the wick drain being directed to the sub-grade drains. The wicking action of the product will hydraulically direct the water that is between the liner and the concrete slab to sub grade drains.
