Minimize the number of joints on a building.á Keep joints wide enough to prevent capillary
action, shaped to direct water
back to the outside.á Joints behind
surface cladding should be made waterproof.á Buildings must not be allowed to hold water
where the potential for freeze/thaw damage
exists due to expansion and contraction.
It is not only the elements of nature, also consider
impact of the people and vehicular traffic.á
Before selecting
any system, consider resealability, subsurface water management, crack
bridging ability and
resistance to de-icing chemicals.
