Characteristics

Efficient vertical drainage of the building  below ground level

Permanent R-value - Does not diminish with time

Inert material which does not contain organic matter - Not-affected by soil or groundwater

Meets CAN/ULC-S701.1 standard

Recommended use

Install SR.Drain™ panels on the exterior surface of the foundation walls, the channeled surface on the interior side, towards the foundation wall, in order to obtain a continuous insulation of the wall and enhancing the effectiveness of a waterproofing system. The draining grooves contribute to channeling sub-surface water away and preventing the built-up of hydrostatic pressure against the structure. The type 3 SR.Drain™ panels are ideal for prolonged groundwater contact applications; with the lowest water absorption rate of the three available EPS types.
