Crack width calculation for swimming pool.
Crack width calculation for swimming pool.
(OP)
Hi all,
Need some advice on crack width requirement for swimming pool structure. The pool is located on an upper floor level. Some literature state crack width of 0.1 and 0,2 depending on the length of water tightness tests to be conducted. SO I am assuming 0.2mm being the limit of crack that is allowed to form in the structure. Is this limit set based on normal concrete or with waterproofing membrane in place? I would have thought if a waterproofing membrane is going to be used to line the pool, crack width limit would be higher but not too high as to cause the lining to fail. Thanks.

Chong

RE: Crack width calculation for swimming pool.
Also if the pool soffit is exposed to view you might still want to adopt the more stringent criteria, depending on the depth the loads are pretty high, and you also deal with a lot of restraint, thermal expansion/contrsction, etc, so more likely to crack and determining crack widths are not an exact science.

Thanks for your quick response. Yes its probably going to be waterproofed with crystalline waterproofing system like Krystol or Penetron. And due to the issue with depth of beam constraint, I might advice the owner to line it as well. FYI depth of pool is 1.2m high.
