When tension is applied to a crack due to thermal cycling or other forces, the cured epoxy crack repair will not typically yield. Epoxy versus Polyurethane Crack Injection Injection Packers. The chemical expansion of the polyurethane (typically 5-10 times its original volume) makes polyurethane very effective at filling voids within the concrete; these voids are typically invisible when you look at the wall and are often associated with the porosity of the concrete. With the crack exposed, channels are drilled on the inside basement wall intersecting the foundation crack. Injection epoxies cure chemically within a specified time and harden further over days and weeks. Polyurethane injections could be done by either low pressure or “surface port” injections (around 20 – 40 psi) or at high pressure (usually between 1500 – 3200 psi).
