Repairing Concrete Cracks Using Epoxy

Panther - Specialists in Pressure Epoxy Injection for Permanent Concrete Crack Repairs for over 20 years. It's often repaired by just filling the crack with hydraulic cement, but to ensure it doesn't fail again, contractors should look for a solution that goes one step further and strengthen the whole area with carbon fiber crack repair that will reinforce the stair step crack in all directions.
Another option for small leaks is to clean off the injection epoxy and use paraffin or crayon to seal the holes. The ideal crack repair process might require widening the crack into a "V" shaped until Epoxy Injection the crack is no longer noticeable. Before deciding whether or not to use the epoxy repair, you will need to confirm that the cause of the crack is solved and no further movement is permissible.
We make and stock the industry's widest selection of concrete crack repair adhesives with specialized materials for architectural precast panels, underwater, low and high application temperatures, underwater concrete crack repair , high structure temperatures, chemical and radiation resistance, large voids, narrow cracks, plate bonding, wooden (laminated) beams, slab delaminations and structures subject to vibration during cure.

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.

Prior to the use of epoxy compounds and due to their versatility and the wide range of available physical and chemical properties of epoxy resin systems, one has to be completely aware and informed before entering the world of epoxies; other than crack repair, epoxy compounds have found a wide variety of uses in the concrete industry.
ArmorPoxy Crack Repair Putty is a 2 part (1:1 mix ratio) epoxy putty that you mix together to fill all types of cracks, including vertical surfaces. Epoxy injection is commonly used to restore the pre-cracking condition of the member without increasing its strength.

Epoxy forms a rigid seal in an injected foundation crack that is prone to re-cracking. This will involve cleaning the surface of the wall, and then inserting the epoxy material into the opening to fill it up from the earth to the surface. Deciding Between Epoxy and Polyurethane Foam for Crack Injection.
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.
Do not allow epoxy to block the port or the crack under it, this is where epoxy must enter the crack. As a consequence, the formerly cracked area has strength exceeding that of forces that would otherwise cause the repaired area from opening outwardly. Both Epoxy resins and polyurethanes are sensitive to water.

If sealing is not properly done on cracks, loss of epoxy resin can occur due to the damage of sealing when injection device is installed. While the main cracks signals a hydrostatic pressure problem, vertical cracks on the adjacent walls could mean there is a settlement problem.
