my deck currently has a rubber membrane that has started leaking. it is at least 18 years old and was topped with indoor-outdoor carpeting. one contractor has recommended using polyurea as a replacement and another is wanting to do the rubber membrane thing. this deck is approx 2200 sq feet and covers my (3) carports, so not leaking is the desired effect. the current structure is a regular frameout with plywood subflooring. a neighbor has a deck done with concrete and said it would not be his choice if done again. what would be a good, reliable, non-leaking, affordable solution? any idea of what is a reasonable cost for NW Arkansas? tired of getting water on my stuff.
