Wa pf units provide waterstop pipe sealing.

Sealing around a pipe through a concrete wall.

When pipes are run through the walls of your foundation they are typically sealed up with concrete hydraulic cement or caulk. The units prevent water infiltration along a pipe through the concrete. If there is a substantial flow postpone the project until water stops moving through the hole. Locate the pipe in the basement wall that needs sealing.

They are cast in a wall around a pipe through a foundation wall floor slabs pools ice rink concrete slabs. Two component polyurethane injects via a standard caulk gun. Edpm puddle flanges provide waterstops when a continuous pipe runs through the wall. Acrylic and latex based caulking.

Use a dry cloth to blot up water that may have leaked through the hole. Requires no drilling into concrete. These penetrations are one of the weakest links in the foundation walls when it comes to holding back groundwater and it s very common for them to leak water. The sleeve pipe may be sealed with mortar tar expansion foam or any other suitable means.

Effectively fills gaps stopping entry of water seepage and soil gases including radon. To make a sleeve a section of pipe two nominal trade sizes larger than the desired pipe is passed through the wall with 2 to 3 extending out either side of the wall. Dust the area around the pipe with an old paintbrush or handheld duster to remove dirt dust and other debris.
