When installing the DPR Drainage system, the basement floor is typically opened up approximately 14 to 16 inches from the wall.
When there is a hot water heater, furnace or other obstruction present, we typically leave the section of the floor intact below it and that is referred to as a "structural floor spacer".
Cinderblock foundations are very porous, a single cinderblock can hold 2 to 3 times it's weight in water!
With cinderblock foundations, weep holes are drilled into each hollow core of the first course of block to release any water that may be holding in the wall cavities.
We only install perforated - corrugated drain tile that is wrapped in a commercial grade filtration material to prevent fine sediments from clogging your system over time.
With a cinderblock or stone foundation we install our Dura-Wall Panels, typically at a height of 24 inches.
Dura-Wall panels are made of a waterproof plastic and are neatly attached to the wall with white matching rivets and joined together with matching connectors and corner pieces.
Prior to re-cementing your floor we install a black dimpled polymeric plastic drain board which protects the weep holes and a 6 mil. plastic vapor barrier over the stone base as shown in the adjacent picture.
In the event where larger obstructions are present, such as an oil tank, we perform what is referred to as an "oil tank drainage field" .
The adjacent picture displays what the finished system and sump pump set up will resemble.
