Pool Inspections

[Dale Marwood]

I have encountered a new construction residential pool that has leaching grout between the under water tiles.

This leaching requires a good scrubbing with a brush to remove and I don't know what might cause this.

Any ideas?

Soluable salts leeching through the grout or plaster is the cause. Often it is worse on new pools because the pool water tries to balance itself with the available calcium. Proper chemistry is necessary and yet it may not totally solve the problem. Start with a comprehensive water test and keep the scrubbing brush handy.
