Foundations Need Insulation.  According to the DOE 20% of energy loss in residential structures can be attributed to losses through insulated foundations.                         

SPF applied directly to the block, or poured concrete foundation walls provides a fully-adhered, monolithic layer of insulation on the outside of the foundation. SPF does not need fasteners to hold it in place,  It attaches chemically  to the surface that it is sprayed to.  This eliminates damage (piercing) of waterproof membrane by metal fasteners.  

There is no shifting with SPF (sheets allow shifting to take place during frost-freeze-thaw cycles and    also during backfill.)  Traditional sheets/drainage boards pull away from the foundation allowing rock and debris between the board and foundation. Spray Polyurethane Foam seamless adhesion eliminates  pulling away from the foundation.

Spray Polyurethane Foam:  Provides a seamless area of insulation and seals cracks and crevices.  Insulates and waterproofs in tight areas and hard to reach areas.  (No gathering of water in cove footing area (at base of the foundation).  Will not settle, adds structural strength, helps to prevent structural foundation cracking, seals cracks and crevices from unwanted odor and gas penetration.   SPF stops moisture driven elements due to its solid nature and sealing abilities.  Applied over the SPF is a black polyurea (bed liner spray) for a hard shell protective coating to double the blockage of water and protect the foam from damage.

SPF is code approved (materials meet building code requirements and are accepted nationwide, safe (contains no urea formaldehyde and cost effective making it the best overall foundation waterproofing system.
