Once approached to the depth of the excavation, when the drainage system may disturb the work on the site (waterproofing casting, slabs or other …), the wellpoint system can be replaced by a “pipeline”.
This system involves the laying – about 50cm below the floor – of a network of drainage pipe inserted in a specific filter sock, buried inside “channels” protected with specific gravel that allows the water to drain inside. This sort of “latex” is attached to one (or more) pumps that suck the falling water, allowing you to work in dry conditions without hindering needles from wellpoints or draining wells, guaranteeing optimal extraction without clogging and without suspended solids.
