An enclosed balcony, deck or elevated exterior walkway with a concrete topping slab or other surface that was leaking or had subsequent structural concerns due to the water entry are common problems that can be easily avoided if some very simple measures are taken in the design and construction process.

Proper application of the waterproofing membrane (whether it be sheet applied or fluid applied) and its flashings are of the utmost importance to ensure that water does not infiltrate into the supporting structure. However, there is another key factor that is often overlooked for long-term performance of a deck, balcony, or elevated walkway, with a topping slab or wearing surface, and that is the drainage of water from the system. The solution is prudent construction that would include an accommodation for drainage both at the top of the wearing surface (concrete topping slab, tile, etc.) and also below the wearing surface at the top of the waterproofing membrane. The sloping of the wearing surface should be such that it adequately drains all water too either an internal drain system, thru-wall scupper or properly detailed perimeter edge flashing. The substrate or deck below the waterproofing membrane should therefore also be sloped to drain and have a space or media provided to accommodate the drainage of water beneath the wearing surface or topping material.

There are a few industry recognized organizations such as the NRCA (National Roofing Contractors Association) for roofing and waterproofing, and the SWRI (Sealant, Waterproofing & Restoration Institute) for below-grade waterproofing and plaza decks that publish a wealth and abundance of knowledge on how to properly construct a roof, waterproofing or plaza deck system.
