{"product_id":"quick-e-retaining-wall-spillway-6-in","title":"Quick-E-Retaining Wall Spillway, 6 in","description":"\u003cp\u003eDrain water out from behind a segmental retaining wall with the Pave Tool Quick-E-Retaining Wall Spillway. The 16-gauge aluminum spillway penetrates the wall face and discharges captured water past the toe of the wall — eliminating the hydrostatic pressure that causes SRWs to bulge, lean, or fail. A 1-1\/2 in back flange slips onto standard 4 in perforated drainage pipe (SDR35, Triple Wall, or S\u0026amp;D), so the spillway integrates with the drainage stone and pipe you’re already installing behind the wall.\u003c\/p\u003e\u003cp\u003eBuilt to NCMA specifications for segmental retaining wall drainage.
