Applied Technologies manufacturers A-T Sealer, a low cost foundation dampproofing coating that retards water vapor transmission.

Dampproofing is the traditional method of protecting a foundation. A-T Sealer is a dampproofing membrane that stops water vapor from passing through a foundation wall and into the basement area. It can be used on either poured concrete or masonry block construction and forms a smooth continuous barrier.

When brick is used above grade to cover masonry walls, A-T Sealer can be used to stop water vapor from getting into the interior living space. Simply coat the above grade exterior of the masonry construction with AT Sealer.

 A-T Sealer will bond to nearly any surface forming a smooth continuous barrier against water vapor.

A-T Sealer is an asphalt based dampproofing that retards moisture movement thought basement walls. When used on an above grade cavity wall, it acts as a vapor barrier.

A-T Sealer WB is an asphalt emulsion dampproofing that retards moisture movement through basement walls. When used on an above grade cavity wall, it also acts as a vapor barrier.

A-T Sealer can be use as a masonry cavity wall sealant.  The masonry course used on the exteriror of a building is porous and will abosorb water.  This water soaks into the masonry veneer and creates a resevoir for water-vapor to then be passed to the concrete masonry unit and to the inerior of the building.

A-T Sealer is sprayed onto the CMU  before the masonry veneer is installed.  Now water vapor cannot be passed from the masonry veneer to the CMU on the interior of the building.
