Epoxy Crack Injection GuideIf you're looking for a Concrete Crack Repair Contractor in Maryland, Virginia, or DC, you've come to the right place. Professional products and training programs for concrete repair, concrete bonding, concrete restoration, concrete coatings and concrete protection including epoxy injection and metering pumps for structural concrete crack repair and control joint fillers in civil engineering, government, commercial, industrial and mro applications.
Strengthening is provided by installing additional reinforcement across the failure plane in combination with the resin injection. At the same Epoxy Injection Crack Repair time the nozzles are positioned and fixed along the entire length of the crack, at approximately 20 cm intervals, with the same material.
The strength of cured bonding epoxy is typically around 7000 psi whereas the tensile strength of concrete is in the range of 275 - 750 psi; clearly, the bonding strength of 2 part bonding epoxy is much greater than that of the concrete foundation wall; making epoxy a good choice for foundation wall crack repair.
If you notice flow problems, it may be connected to the French drain; we repair and replace the drains around your foundation and also do the periodic pressure cleaning which assures you a maximum quality of drainage by eliminating the residues of earth, mud or ferrous ocher in the drain.
Place the sand in the crack to a level no more than 1⁄4" thickness of the member and apply the injection epoxy as described in step 2. The epoxy level will drop as it penetrates the sand, but should cure and provide a seal to the bottom of the crack.
As a result of our extensive experience in performing epoxy crack injections, AquaGuard Injection & Waterproofing® uses epoxies with differing viscosities as dictated by the characteristics of the concrete crack being injected; this is required in order to prevent the epoxy from bleeding through the crack into the soil on the outside during the curing process, which takes several hours.
Injection ports are placed over the cracks, which removes the need for holes to be drilled. Polyurethane is flowing into the crack, but not showing up at the next port. Epoxy injections are considered structural repairs and will weld the foundation back together when done properly.
The former being mainly used for structural crack repair and the later mainly finding use in situations, where movement is expected or water leakages have to be stopped quickly. While there are common cracks and damage found in concrete and foundation not all problems can be resolved with the same solution repeatedly.
In this method, mixtures of grout may contain cement and water or cement plus sand and water, depending on the width of the crack. Most cracks develop within 30 days of the concrete being poured, whether or not leaking during this period. Spencer says the only time contractors don't seal a slab is when water is already flooding the basement through the floor cracks.
This article limits itself to the repair of concrete cracks in general and specifically to cracks of structures 16 inches in thickness or less. While there are still companies that will use epoxy, the fact is, follow-up repairs will almost certainly be needed as this material has been proven to leak.
Utilizing a state-of-the-art pressurized grout pump, cement materials are transported and applied to the repair site resulting in unrivaled results. Shallow concrete cracks on horizontal surfaces such as bridge decks or the tops of pier caps can be repaired by gravity feed using epoxies or high-molecular weight methacrylate (HMWM).
