CHICAGO BUILDING RESTORATION MASONRY REPAIR & WATERPROOFING ...Where Your Satisfaction Begins™
________________________________________________________________________
Lintels support the masonry over openings in a wall, such as at doors or windows. Lintels are generally constructed of steel angles, channels, wide flange beams, or reinforced masonry bond beams.
Steel lintels are susceptible to corrosion through repeated cyclical exposure to moisture. The corroded steel can expand by up to 10 times its thickness. This corrosion and expansion of the steel exerts tremendous force on the adjacent masonry, which causes movement and eventual cracking in the wall.
Severely corroded lintels may require complete removal and replacement with new galvanized steel members.
