About this detail

Sanitary sewer and rain leader pipe penetrations pass through a concrete foundation wall and below footing zones of influence. Pipes passing through the wall require a Schedule 40 steel wall sleeve with a minimum two-inch water stop, sealed with a watertight pipe seal such as a Link-Seal, along with silicone sealant in the annulus. Exterior penetrations extend the Schedule 40 ductile iron pipe sleeve six inches beyond the foundation wall and tie into the foundation waterproofing membrane per architectural specifications. Below the footing, pipes must maintain a forty-five-degree zone of influence with no pipe penetration within six inches of the structurally tied floor and a maximum depth of three feet below the footing, requiring structural backfill for deeper installations.
