Is the main cause of leakage.
How to construct a deck correctly, must be casted in concrete only in which the technician will have to pour concrete in the wood with steel reinforcements inside. The resulting concrete is the same. And the concrete of the deck should be 12-15 cm thick so that it is opaque enough to prevent rainwater flowing down the drain.
