Lanai Decking - Waterproofing

This is what can happen (and usually does happen)when a rug, tile or any type of flooring is installed over waterproofing that cannot ventilate. Water gets in through the carpeting, tile grout or any opening and gets trapped. In this case, the waterproofing was the weak link.





When the carpet on this lanai was removed to see why ants were getting into her unit, this is what I found.


The sole reason for this occurance or damage is because the water was being trapped and could not ventilate. The rest of the decking was in fine condition. The ants took advantage of the water and penetrated into her unit. I removed the carpeting, killed off the ants and now all appears to be fine. This unit happened to be on the first level so there was no leakage to a unit below.

for waterproofing...this situation happens all the time, carpet, tile etc. that traps water in against the waterproofing which ends up failing. The Assoc must stop that from happening, the results can be very expensive when over wood substrate and/or concrete. Dry-rot will occur in wood and rusted rebar will occur in concrete decks, which is much more expensive to fix. See our website at www.deckexpert.com for more decking information.
