Form-A-Drain Plus is the 3-in-1 foundation solution that forms footings, provides an integrated drainage system and can be easily adapted to vent radon where needed.Designed for basement applications, Form-A-Drain Plus consists of lineal sections installed as the foundation footing forms. Unlike standard wood forms, Form-A-Drain Plus lineals stay in place permanently after completion of the concrete pour and because they form a complete sub-slab perimeter loop around the foundation, Form-A-Drain Plus functions as a foundation drainage and a radon collection system as well. Since it stays in place, Form-A-Drain Plus also shaves valuable time from the construction schedule; there’s no need for a crew to return the next day to remove, strip, clean and transport forms to the next job site.Features & Benefits Drainage system parallel to footing below foundation walls relieves hydrostatic pressure on walls and slabs, reducing risk of cracking. Greater water intake capacity ensures rapid collection of groundwater and minimizes possibility of basement water infiltration. Strong, rigid PVC construction minimizes possibility of system failure due to a collapsed or crushed drainage system. Level installation ensures uniform drainage of foundation and makes it easier to set wall forms and masonry blocks. 4" Couplings available as special order - call for details - 541-341-3390
