Strengthening and preserving concrete structural lifespan

Concrete Repairs

We are a concrete repairs specialist, offering a range of expert concrete refurbishment and repair services, including concrete repair and protection, cathodic protection, carbon fibre strengthening and leak sealing.

Over 20 years’ experience as a concrete repairs specialist

We have over 20 years’ experience in the concrete industry, repairing water and wastewater industry assets and concrete structures including: aqueducts, service reservoirs, water storage tanks, water towers, water and waste water treatment plants, storm tanks and silos.

We use a varied range of specialist repair mortars in our role as a dedicated concrete repairs contractor. These include a range of sprayed concrete repair systems that are tailored to each specific concrete repair through investigation by our experienced staff.

Over the years we have been able to develop the specialist knowledge to identify, plan and implement the correct approach for each individual concrete repair requirement for our clients.

Resin Injection

Our fast-acting hydrophobic resin injection systems are an effective solution to leak sealing problems, providing a waterproof seal that protects structures from water ingress. Other systems provide structural repairs to cracking in concrete structures.

Cathodic Protection

We install and replace cathodic protection systems to significantly increase the lifespan of structures.

Culvert Repair

Our teams are experienced in providing culvert erosion repairs to inlet and outlet cold water culverts during power station shutdowns or statutory outage periods.

Expansion Joint Repair

We have unparalleled experience in joint repair, offering mechanical and expansion joint repair solutions for perished or damaged joints and cracks.

Carbon Fibre Wrapping

Carbon fibre wrapping is an innovative alternative structural strengthening system. Our team is well equipped with the high level of skill and expertise required for the installation of this unique solution.

Ladder & Handrail Installation

We are specialist installers of cost-effective galvanised ladder and hand rail systems.

Why do you need a concrete repairs specialist?

In untreated concrete, the process of carbonation is nearly impossible to avoid once exposed to the elements. Carbon dioxide slowly penetrates the surface of the concrete, reacting to moisture and calcium hydroxide that is found in concrete. This forms calcium carbonate that initially hardens the concrete, raising the compressive strength. Alkalinity then reduces in the concrete and it starts to breakdown. Depending on the permeability, concrete carbonation may advance at a rate of 1 – 5mm per year. As carbon dioxide travels deeper into the concrete it reaches the steel reinforcement embedded in the structure. As the concrete around the steel is broken down by carbonation the corrosive effects of the air and water rust the steel causing it to expand, spall and crack. This, in turn, causes a high rate of failure to the surrounding area.

A concrete repairs specialist will remove the area around the spalled steel, removing concrete back to sound substrate. The exposed steel would then be cleaned and prepared back to bright steel before treatment to protect it in the future. Depending on the scope of works, cathodic protection (corrosion protection system) might be used before the concrete repair mortar of choice is used to fill out the repair area. The surface area of the concrete structure can then be prepared by abrasive or water blasting and a fairing coat applied to bring the structure back to its original depth. Finally a waterproof coating is applied.
