Does brick veneer need expansion joints?
Vertical Expansion Joints in Brick Veneer: For brickwork without openings, space no more than 25 ft (7.6 m) o.c. For brickwork with multiple openings, consider symmetrical placement of expansion joints and reduced spacing of no more than 20 ft (6.1 m) o.c.
Does stone veneer need control joints?
There are no code or industry requirements for control joints for adhered stone veneer.
What is the difference between expansion joints and control joints?
Control joints can be isolated within the plane being treated (brick facades, concrete sidewalks) while expansion joints must bisect the entire structure thereby creating a gap throughout all of the building elements—foundation, walls, curtainwalls, plaza decks, parking decks, floors, and roof.
How often do you need masonry control joints?
The National Concrete Masonry Association (NCMA TEK 10-2C) recommends that control joints be spaced at 25 feet or 1.5 times the height of the wall, whichever is less.
Can we avoid expansion joint?
You can provide shrinkage strips at required intervals and avoid expansion joints. Thank you sir, for this advice. Actually, we have used shrinkage strips (pour strips) in building exceeding 45m length.
How do you seal vertical expansion joints?
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.
At what length should expansion joint be introduced?
An expansion joint placed at mid-length opened as much as 3/4 in. (19 mm) at the roof level. The width of the joint tapered to zero at the basement level. The magnitude of this movement is directly attributed to thermal strains caused by the heat generated by the ovens, coupled with outside temperature effects.
