![]() ![]() This dry polymer foam is swept up with a push broom. A certain amount of foam will seep out of the holes in the flooring as the pressure mounts. This procedure is repeated at each spot until coverage is complete. Then, foam is released until maximum pressure is determined. A custom-designed injection gun connected to the supply of polyurethane foam is then placed in each hole. Watching a video of a CFS commercial application of polyurethane foam injection demonstrates precisely how efficient and mess-free the operation is.Īfter CFS sales technicians assess the problem and diagram the solution, company-trained experts drill a series of small holes. Legacy aside, the company uses the latest technology to address shifting and sinking foundations and flooring. The technicians at Carolina Foundation Solutions have seen plenty of changes over a century-plus of work experience in the foundation business. Any excess foam that seeps out of the holes or seams is brushed away. It requires small holes with diameters rarely larger than 5/8 of an inch, so minimal impact. ![]() Polyurethane foam injection, essentially a type of pressure grouting, provides cost-effective repair solutions for cracks in house foundations or warehouse flooring. This solidified base prevents additional movement and can even lift the settled areas of the concrete slabs. The foam consolidates loose and soft soils, a natural consequence of shifting earth and fluctuating moisture density. The material is lightweight but strong enough to support industrial weight as soon as forty-five minutes after application!īecause it's liquid, polyurethane foam flows into gaps or voids in either the base of the concrete or the top of the soil. The foam can also be used to lift warehouse floors and commercial walkways. Polyurethane foam injection is a two-component, high-strength hydro-sensitive structural polymer that can be used to fill voids and cracks and seal leaks. Adapting techniques from other shared applications, repairers make a series of small holes in the imbalanced flooring or cracks and inject them with polyurethane foam. Today, polyurethane foam injection can fix concrete fractures and settlement with little hassle and at a fraction of the historical cost. Gone are the days when cracks and settling within concrete mandated messy, invasive, time-consuming, and costly repairs with traditional pressure grouting or slab jacking procedures. Fortunately, repair techniques for cracked or uneven concrete slabs have evolved-significantly. While concrete has no equal, it remains susceptible to shifting, settling, and cracking. However, one element of home construction has hardly changed: concrete for foundations, slab floors, garage floors, driveways, and patios. Over the past 20 years, much has changed in home construction, from intelligent HVAC systems to new building materials.
