Seal leaks in concrete or masonry with crack injection and curtain grouting of our Prime Flex polyurethanes and AR acrylate resins. Prime Resins offers superior solutions for stopping leaks in every type of environment.
Sound concrete relies on a sound substrate. Stabilize soils and fill voids with our polyurethane and acrylate foams and gels. We make chemical grouts for permeation and compaction grouting in wet and dry conditions.
Slab lifting and slab stabilization with polyurethane foams offers many advantages over traditional mudjacking. Only Precision Lift is engineered to tackle underlying issues and slab lifting with precise, dependable results.
Protecting concrete usually means shielding it from the elements of nature or from harsh manmade chemicals. But it’s not just concrete that needs such protection. Corrugated metal pipe, steel surfaces, material hoppers, rail cars and masonry all can come in contact with corrosive or abrasive materials or harsh conditions.
Spalled concrete is concrete that is chipped, cracked and deteriorating. This often happens at a joint.
You can repair a seawall or bulkhead with Prime Resins chemical grouts: fill voids, stabilize loose soil and seal leaks at a fraction of the cost of wall replacement.
The need for crack repair in concrete structures can be caused by many different factors. Damage can occur to the concrete in situations where direct impact puts stress on one area of the structure.
The geotechnical needs of DOTs and other agencies responsible for roads and bridges are vast. Issues include: Culvert repair Soil stabilization Void filling Concrete slab lifting Sinkhole remediation Slope control Slough control in tunneling

Client: U.S. Coast Guard
Contractor: Brantley Construction, Charleston, S.C.
A brick and stucco lighthouse, built in 1812, stands on the southern point of North Island, a 30-minute boat ride off the coast of Georgetown, S.C. After nearly two centuries of service, the Georgetown Lighthouse continues to be an important navigation aid for the shrimp boats and pleasure craft that travel out of Winyah Bay through the narrow channel between North Island and South Island. Despite many years of assault by sea air, wind, and rain, the historic lighthouse is in remarkably good condition.
During a routine inspection in preparation for repainting, the Coast Guard found a few exterior cracks, areas of delaminated stucco and a handrail that needed to be replaced. They also identified a more serious condition that needed immediate attention. The brick and mortar foundation showed signs of deterioration caused by constant contact with salt water in the surrounding soil. Apparently, during storms, rain and salt spray would pelt the lighthouse and run down the sides, permeate the sandy topsoil and accumulate next to the foundation.
To stop the deterioration of the foundation, the Coast Guard engineers specified a technique called “curtain wall grouting.” This involves injecting a polyurethane grout completely around the structure to create a waterproof barrier. The specifications for this project called for injecting Prime Flex 910 through soil probes driven 30 inches into the ground, spaced 30 inches apart.
The Coast Guard contracted Brantley Construction Company of Charleston to repair and repaint the lighthouse. General Materials, Inc. in Charleston supplied the necessary repair materials.
Prime Resins provided onsite technical installation assistance. When injection started, the Prime Resins rep noticed that the specified 30-inch depth for the soil probes was too shallow to allow sufficient horizontal migration of the grout. Most of the grout was following the path of least resistance upward through the drier sand, and alongside the probe pipe. It also became apparent that the specified distance between the probes was too great for the grout to migrate to the grout from the previous probe. To ensure a good watertight curtain, the rep recommended changing the depth to five-and-a-half feet and the distance between probes to 18 inches.
To stop the grout from flowing back up alongside the probe pipe, he suggested that at each new probe the crew start by injecting a small amount of Prime Flex 910 with 5% catalyst and then waiting about 90 seconds. The grout traveled up a short distance alongside the probe, cured and created a gasket around the pipe. When they resumed injection, this gasket forced the rest of the grout to migrate outward into the surrounding soil. To ensure complete protection, the rep recommended that they repeat the process with the injection probes midway between the first set of probes.
General Materials supplied Prime Bond 3100 and Prime Gel 2000 to complete the other repairs. These products were used to repair the cracks and reattach the delaminated stucco.
