Where is the water going?

(Continuing from the Frequently Asked Questions page)

In southern California there is a lot of clay in the soil. Clay has varying degrees of expansion potential. This means that when clay absorbs water from a leak in the pool, it will actually swell and expand its total volume. This can lift and crack even the heaviest steel reinforced concrete slabs, either under the house or around the pool. It can also exert lateral pressure on pool walls, causing the pool shell to crack. Repairing this type of damage can be expensive. It is always the best option to FIND THE LEAK AND STOP THE WATER!
