"Nothing on earth is so weak and yielding as water, but for breaking down the firm and strong, it has no equal."
- Lao-Tsze -

 That persistent drip, drip, drip that continues whether you are there or not. Every building owner knows the  problems associated with leaks and the damage they cause when ignored. Now magnify those problems by trying to get a plain concrete slab to function as a roof.

 What are the most common problems a parking deck faces? Salt carried onto the deck by cars in winter causing spalling of the surface. The second is rain, migrating through tiny fissures in the deck, dissolving minerals and depositing them on the cars below. The third is corrosion of the steel reinforcement which damages the concrete and attacks the steel resulting in early loss of strength and potential failure.

These photos show the treatment of a central Kentucky parking deck and adjacent planters with true water proof treatments. The parking deck is treated with a fluid urethane material in repeated applications. The planters received a bentonite  sheet membrane.
