We have an approximately 9500 ft2 (882.6 m2) pool that was built and finished in midsummer. Four weeks later, the pool has developed "spider web" cracking in the bottom. We need to have a compressive strength test done. Our crew is on site now and is going to pull a 4 in. (101.6 mm) core sample for testing. I need to know what procedure to follow and where to send the sample for testing.

Consult with a local engineering firm that is qualified to develop a coring plan, obtain cores, and perform testing in accordance with ASTM C42/C42M or ASTM C1604/C1604M. Please refer to ASTM C42/C42M for further guidance.
