EPDM roofing or pond liner is a cost-effective alternative to proprietary systems to drain water under the decking and keep the space beneath the deck dry. Learn how to lay out a pattern to cut successive sheets of EPDM from, install the sheets to create sloping swales between the deck joists, and how to tie the membrane into the wall of the house and a gutter. See what types of manufactured underdeck drainage systems are on the market.
Topics Include: EPDM materials and sources Drainage design options Building Code limiting factors Creating slope between joists Membrane Layout Making a Template Splash guards Installing the membrane Spacing decking off membrane at ledger Gutter - Type, location, concealing Retrofit option Manufactured underdeck drainage systems Above Joist Under Joist without finish ceiling Under Joist with finished ceiling Cleat/bracket Sloped Panels Corrugated roof panels Decking with integral waterproofing Grooved board gasket.
