Resin Crack Repair

What is Resin Concrete Floor Repair?

Cracks in concrete floors and screed are extremely common and one of the biggest causes of failed floor coatings and finishes. Once a crack appears it is important to repair it as quickly and professionally as possible to extend the life of your warehouse or industrial surface. 

The method of repairing a crack varies on the width, depth, floor finish, subfloor and usage of the area. But as a general rule the repairs are carried out by cleaning the opening where possible and filling with high strength 2 component epoxy resin, polyurethane or cementitious crack filler.

Our grouts work very well to fill voids and cracks, and they are used for anchoring in structural applications.

Our epoxy injection grout, for example, is a low viscosity grout used to fill gaps and cracks in resin as well as concrete floors. It effectively seals both sides of the crack to prevent any resin drainage or further damage to the site in future. We have a versatile range of resin grouts which are used to fill fine cracks and larger ones alike without any hammering. Structural repairs through injection resin to your floor is an ideal method for prolonging the life of resin floors which have undergone crack and joint repair.

How do you fix a crack in a resin floor?

There are three main methods of crack repair.

  1. Chase and Fill – This method involves opening the crack up by chasing it with a floor saw and diamond blade to make the opening bigger and removing any friable or damaged concrete. Specialist strong epoxy crack repair resin is poured into the crevasse until the crack fills to the top of the concrete surface and finished level with a trowel. It is important to monitor these repairs as after a while they may “sink” and require topping up. This is due to the resin sometimes needing more time to find its way through to the bottom of the crack.

  2. Crack Injection – When crack repairs are of the upmost importance structurally, we would recommend crack injection. The crack and its surrounding area are thoroughly cleaned and prepared to ensure proper adhesion of the injection material. This may involve removing any loose debris, dust, or contaminants from the substrate. Small plastic or metal nipples, also known as injection ports, are inserted into the crack at regular intervals.

    These nipples serve as access points for injecting the repair material into the crack. The nipples are securely sealed to the surface using an appropriate sealant or epoxy adhesive. This helps to prevent the injected material from leaking out during the injection process. A specialized repair material, such as epoxy or polyurethane resin, is injected into the crack through the nipples using a pressure injection system or a manual injection gun.

    The material is forced into the crack, filling it from the inside out and bonding with the surrounding substrate. This method ensures that the whole crack is being filled as much as it can, this is because you can visually see the resin coming out of each of the injection ports. This method can be used for repairs to damaged floors and walls.

  3. Stitch Pinning – If there is major structural movement in a concrete subfloor usual methods can fix the original crack, but new issues may well appear where the floor is still trying to move. In this case stitch pinning is an option. This is basically putting numerous saw cuts across the existing concrete crack, drilling a hole at each end of it and the affixing a metal “staple” with resin to try to fight against the movement of the slab.

What is the difference between epoxy and resin flooring?

Epoxy is a type of resin. There are a number of different resin flooring systems – epoxy, polyurethane, mma, acrylic, polyaspartic etc. They all have different properties and characteristics. Please contact our office for free technical advice if you need some guidance in choosing your flooring solution.

Why is my epoxy floor cracking?

Although epoxy has an extremely high compressive strength making it great for industrial applications and wearing characteristics, it is also brittle. This means that if the subfloor that it is attached to is sound, secure and free of movement it will very rarely crack. If it is cracking, by far the most probable cause is movement of the subfloor, self levelling compound or industrial floor screed that it is attached to. Expansion joints in concrete are a very common cause, sometimes these are not dealt with correctly by contractors and sometimes are completely ignored. If the cracks that you are seeing are in relatively straight uniform lines then this is probably the answer.

The only other reasons that epoxy floors crack is down to thermal shock that some systems are not designed to handle. We supply and install specialist resins that can handle extreme temperature fluctuations, but it is always important to consider this information before choosing the correct resin system for your application.

Which is the most common method of crack repair?

The most common method of crack repair is to chase and fill. As described above, this is the least time consuming and value for money method that can be used. This epoxy floor repair can however be expensive if the crack that you are filling is leading to a void below the surface.
