As tidal flows rise and fall, water pushes its way in through cracks, joints, and defects in seawalls. The water pushes in on incoming tides and flows out on outgoing tides. As the water flows out, it carries sand and soil with it which causes undermining of the structure, voids to form, and deteriorates the structural integrity of the seawall. This cycle is exacerbated during periods of heavy rain which continue the outflow of soil. AP Fill 720, AP Fill 700, Spetec PUR H200, Spetec PUR H100 and Spetec PUR HighFoamer are semi-rigid hydrophobic polyurethane foams that react with moisture in the soil and expand to fill voids while they permeate sandy soil to form a solid, strong, watertight mass. They have been used extensively in seawall applications to seal cracks, voids and defects (as well as for filling voids and stabilizing soil). In some cases AP Lift 475 and AP Soil 600 may be used as well.
“We use Alchemy-Spetec for all our chemical grouting in seawall and soil stabilization projects throughout Florida and the Southeast. AP Soil 600, AP Fill 700, and AP Lift 475 have provided outstanding results on an extensive number of projects. After using a variety of other products in the past, we now believe that Alchemy-Spetec is second to none. From customer service to tech support, they have surpassed and exceeded all expectations.”
