Pool Construction Joints

Large pools are often broken into several concrete pours, in an effort to prevent concrete shrinkage cracks opening too wide. Construction joints are detailed between concrete pours.

Pool construction joints, if not well positioned, well detailed and well constructed, are a common cause of pool water loss. Waterstops are cast in construction joints in an effort to make the joint water tight. It is also important to understand that mastic used to seal a construction joint is only intended to keep dirt out of the joint, not to make the joint watertight.
