Worried about cracks in concrete at your property? Whether the damage appears superficial or not, it’s definitely worth getting cracks inspected and repaired before the damage potentially worsens. Large cracks and degrading concrete can potentially impact the strength and support of the structure, which could lead to potentially dangerous consequences. It’s always best to act on the repairs the moment you notice before they become safety hazards.

At Concrete Remedial Systems, we specialise in restoring, repairing and reinforcing concrete on a grand scale, bringing large and small builds back to working order. We accept contracts covering London and the South East, addressing failing concrete in old buildings, reservoirs, sea walls and any concrete structures ensuring further longevity. Not only do we carry out extensive repairs, we also apply coatings to concrete to provide damp proofing or corrosion resistance to name but a few.


Professional repairs with Concrete Remedial Systems


Addressing concrete repairs without experience comes with many pitfalls. Hiring a contractor to carry out the repair work on your behalf is not only more convenient but will ensure that the repairs are done to a high standard and will commonly come with a warranty for their works.

Our team has over thirty years of experience in restoring, repairing and coating concrete structures. Our range of concrete repair services can increase the design life of a structure, saving money on large intrusive works whilst still keeping the structure stable and safe.


1. Cracks


We can repair and seal cracks that leave concrete structures ugly to look at and prone to problems. We carry out a full inspection of the concrete to establish the extent of the damage and properly assess how to repair as different cracks require different materials to fix. Depending on the severity and number of cracks, the repair job can take a day or more than week.


Small cracks


Cracked Wall


Hairline cracks may not appear to be an issue, other than their appearance, but small cracks are breaches in the concrete structure. In fact, if the concrete was preventing ground water from entering a building then a smaller crack can actually transmit water at a faster rate than a larger crack through the process of capillary absorption. If hairline cracks, during a survey, can be shown to pass through the whole section of the concrete than these would need to be addressed.


Large cracks


Large Cracked Wall


For more significant cracks, they take a lot more work to repair successfully.  Whereas with smaller cracks we can inject a hydrophobic resin into the concrete and just make good on the surface, a larger crack needs to be racked out back to sound concrete, cleaned, prepped and reinstated with a repair mortar.

2. Degraded concrete


Degraded concrete


Aged concrete can start to crumble and become prone to spalling, which is when pieces of concrete delaminate away from the surface. Old buildings with degraded concrete can sometimes be renovated, restoring the concrete instead of replacing and rebuilding the structure. Through removing the damaged, unstable concrete down to structurally sound concrete, we then apply a bonding agent and reinstate with a specific repair mortar. The end result is a strong and resilient repair job that restores the concrete back to full stability and aesthetic appearance.

3.  Joints




Concreting is not an exact science and often when being formed, the joints can have voids and require sealing. We can re-establish the joints, preventing any further leaks and stability issues. Similar to how we repair cracks, we inject a resin into the joint to seal it internally and sometimes, as a belt and braces approach, we’ll also install a ‘bandage’ over the joint externally.

4.    Water transmission


Waterproofing on a flat roof


Concrete is persistently susceptible to moisture, especially outside facing surfaces that are unprotected against rain and harsh weather conditions. Waterproofing is essential for ensuring the concrete’s longevity. Prevention is definitely more preferable to costly repair works down the line.

To protect structures from water transmission, we apply cementitious coatings to concrete to ensure a water-tight layer that will protect the structure. We use a variety of different materials to ensure the level of protection the concrete requires, which will vary on the exposure and how much stress the surface is under. We use cementitious and epoxy coatings among other materials.
