To control the expansion and protect the wall structure from cracking under pressure masons install vertical control joints at specific locations.
Brick wall expansion joint sealant.
Colorseal seismic colorseal watertight primary seal in wall expansion joints a wall expansion joint seismic colorseal colorseal is a silicone coated precompressed primary seal for high movement wall joints.
Joint sealants and related materials control joints in concrete masonry construction are classified as butt joints where the sealant is exposed to cyclical tension and compression as the joint expands and contracts.
Sold as 3 pack.
Seismic colorseal ensures watertightness in vertical plane structural seismic and abutment joints in virtually any substrate.
It seals and waterproofs the crack which helps to prevent further damage.
Polyurethane mortar joint sealant is a construction grade crack sealant specifically designed for repairing brick and block mason joint.
Polyurethane mortar joint sealant remains flexible and extremely durable after it has dried.
These joints will absorb the pressure created by the expansion by giving the masonry wall flexible space to expand.
Expansion joints must be sealed with a flexible sealant like quikrete self leveling polyurethane sealant or quikrete non sag polyurethane sealant or an expansion joint strip to prevent water from penetrating the joint and deteriorating the sub base.
