servicesStructural Repairs & Protection

Repairing what carries the load

Structural repairs aren’t cosmetic. They’re about keeping the structure working the way it was designed to. When concrete cracks or breaks away, and when reinforcement begins to corrode, load paths are disrupted. The structure still stands, but it’s no longer working efficiently.

We carry out concrete repairs to beams, columns, slabs, soffits and walls by cutting back to sound material and removing anything that can’t be relied on. Exposed reinforcement is cleaned, treated and protected before the concrete is rebuilt using high-performance repair mortars selected for strength, durability and compatibility with the existing structure. Each repair is designed to reinstate continuity so loads are shared and transferred as intended.

Cracks are treated as points of entry, not surface defects. Where cracking is present, we use resin injection systems to bond the concrete back together and seal the routes water and chlorides use to reach the steel. The aim is to stabilise the element, stop ingress and prevent corrosion from continuing unseen.

This approach restores structural performance while reducing the risk of repeat failure. The repair becomes part of the structure again, not a temporary patch applied to it.

Protecting concrete from future attack

Repair alone doesn’t solve the problem. If the environment that caused the damage stays the same, deterioration starts again — often out of sight.

We apply protective systems designed to interrupt the processes that break concrete down over time. Anti-carbonation coatings reduce the ingress of carbon dioxide, preserving the alkalinity that protects steel reinforcement. Without that barrier, corrosion progresses quietly beneath the surface.

Protective coatings and sealers provide an additional layer of defence. They limit the movement of water and chlorides into the structure while allowing internal moisture to dissipate safely. This balance prevents pressure build-up, reduces the risk of further corrosion and allows repairs to perform as intended over the long term.

Where exposure conditions are more severe, we install corrosion management systems such as galvanic anodes. These systems actively control corrosion at the steel, operating continuously in the background without maintenance or intervention. Over time, they slow deterioration, extend service life and protect both the repair and the surrounding structure.

The result isn’t just a repaired surface. It’s a structure that’s better equipped to withstand the environment it operates in.

Designed for live, operational environments

Most of the structures we work on don’t close. Car parks remain open to the public. Podium decks stay in use. Basements, service yards and occupied buildings continue to operate every day. The structure still has to function while the work is being carried out.

Our repairs are planned around that reality from the outset. Works are broken into clearly defined phases so access can be maintained wherever possible. Areas are segregated, routes are managed and interfaces with live operations are controlled. We coordinate closely with clients, consultants and building managers to align programmes, manage access constraints and keep people moving safely through the space.

Disruption is managed deliberately. Dust, noise and vibration are controlled through method selection, sequencing and the use of specialist equipment. Higher-impact activities are planned around periods of lower use, and temporary measures are adjusted as the works progress.

The result is work that is delivered safely and predictably, without unnecessary disruption. The structure remains operational, and the repairs are carried out in a way that respects the environment they’re being installed into.

Standards, systems and accountability

Every repair is delivered in line with recognised standards, including BS EN 1504, and using manufacturer-approved systems. Methods aren’t chosen for speed or convenience. They’re selected based on how the structure is used, the environment it’s exposed to and the service life it needs to achieve.

Repair strategies are developed to suit real conditions on site. Loading, movement, moisture exposure and access constraints are all considered before work begins. The objective is consistency and predictability, not short-term gains.

Defects are recorded, repair techniques are defined, and materials are documented as the work progresses. Asset owners are left with a clear, traceable record of what was done and why those decisions were made. This creates accountability and supports future maintenance planning.

The result is work that stands up to scrutiny and performs over time. The focus stays on long-term durability, not quick fixes that need revisiting.
