control joints in concrete slabs at poolside patio
control joints in concrete slabs at poolside patio
(OP)
Can I get away with 20 foot spaced control joints in a concrete slab that is 4 inches thick that surrounds an in- ground pool at a country club. The control joint is about 1/4 inch deep. The area is somewhat irregular in shape requiring an unsymmetrical control joint pattern with maximum spacing of 20 feet

I would suggest control joints at 8 to 10 feet maximum in accordance with PCA requirements. Panels should be approximately square, not rectangular.

Also, the control joint depth for a 4-inch slab should be 7/8" - 1", and saw them as soon as possible after placement, but in no case more than 12 hours after placement, preferably sooner.

I also prefer using a "Sofcut" saw, if available.
