Our FillFoam™ is a pre-expanded open-cell foam formula with ideal characteristics for foundation backfilling. FillFoam™ is composed of a resin pre-expanded with air, then introduced to a hardener completing the compound. FillFoam™ is noted for its ability to support and protect the existing foundation, wall and sub-structure from further damages caused by ongoing settlement, shifting and cracking of the concrete block walls or slabs. FillFoam™ offers superior thermal and acoustic properties that outperform the traditional closed-cell foams. This makes Fillfom™ an excellent choice for property owners looking for high-quality solutions to foundation backfilling challenges.
