Brick Wall Expansion Joint Sealant

Seismic colorseal ensures watertightness in vertical plane structural seismic and abutment joints in virtually any substrate.

Brick wall expansion joint sealant.

These can be neutral curing low modulus silicone expansion joint sealants polyurethane expansion joint sealants or polysulphide expansion joint sealants now more commonly replaced by modified polymer or hybrid polymer. See tek 19 6a joint sealants for concrete masonry walls ref. 6 for more detailed information. Where concrete masonry is used as a backup for veneer or in multi wythe applications consider the following.

Expansion joint mastic sealants a selection of mastic joint sealants suited to expansion joints in concrete brickwork and other substrates subject to natural movement over time. These joints will absorb the pressure created by the expansion by giving the masonry wall flexible space to expand. Differential movement expansion joints flexible anchorage movement sealants. Width of expansion joint m and ei percent extensibility of the expansion joint sealant material.

For brickwork without openings space no more than 25 ft 7 6 m o c. To control the expansion and protect the wall structure from cracking under pressure masons install vertical control joints at specific locations. Vertical expansion joints in brick veneer. For brickwork with multiple openings consider symmetrical placement of expansion joints and reduced spacing of no.

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. Selleys brick and concrete silicone selleys brick concerete silicone sealant provides a superior waterproof seal and high flexibility. Ideal for joints in walls patios floors fencing windows and expansion joints in concrete around the home. A wall expansion joint seismic colorseal colorseal is a silicone coated precompressed primary seal for high movement wall joints.

The width of an expansion joint is typically chosen to match the width of the mortar joints for aesthetic reasons in which case the typical distance between control joints will typically be less than. The depth of sealant should be approximately the joint width to reduce sealant strain and hence extend sealant life.
