Waterproofing & Spray Foam Insulation for the Putnam & Duchess, NY Areas
Waterproofing an old stone foundation from the exterior with “Closed Cell” spray polyurethane foam provides a water tight seal from the outside.
Closed cell spray polyurethane foam provides more than 3x the waterproofing and 4x the impressive strength of Extruded Polystyrene (EPS) which are the pink boards sold at Home Depot, Menards, Lowes, etc. These pink boards allow water to permeate through them reducing their thermal efficiency and letting water through. Closed Cell when applied to a crawlspace or basement wall sprayed seamless so no water is able to penetrate. Sought is this important? Like clothing when wet, it does not insulate nearly as well. In applications below grade, there is nothing but moisture and ground water saturated in the soil. Closed cell spray polyurethane is the only logical answer for a seamless waterproof insulation.
