"Wall Sweating Problems"
Time-Tested Performance

The surfaces of most common concrete buildings have an affinity for water molecules. This molecular fill is proportional to relative humidity. At saturation levels, all voids, pores and capillaries can become completely filled. When the atmospheric condition, inside or outside, which causes the excessive moisture in the first place, is alleviated, the porous wall may become filled to the saturation point with moisture in liquid form.

This condition then provides an excellent opportunity for vapor travel within a wall. In its travels the vapor may contact a cold area or “dew point”, and condense in sufficient quantities to reach the interior wall surfaces, to appear as wall “sweating” or “bleeding”. Both sweating and condensation can be greatly affected by temperatures, humidity, wind velocity, soil moisture conditions, etc.

These conditions, if allowed to go unchecked, can cause peeling of paints, spalling, formation of mildew, and efflorescence resulting in heavy maintenance costs. All porous masonry materials can experience these problems unless proper steps are taken. Due to its unique formulation, SEAL-IT Concrete Sealant can stop this type of wall sweating.

AGPRO GRAIN - DIVISION OF SASKWHEAT POOL. Concrete Tunnel was not useable in spring with 1/2 foot of water on ground. SEAL-IT came in and stopped 95% of the water seepage with just the use of SEAL-IT CONCRETE SEALANT.
