The materials
we specify.

A polymer-modified, fibre-reinforced, high-build cementitious mortar for reinstating reinforced concrete. Our default choice for columns, beams and soffits where an R4 structural repair is required.

A single-pack zinc-rich epoxy primer applied to reinforcement after cleaning to SA 2½. Provides active galvanic protection and passivates the steel prior to reinstatement.

A protective coating applied to the whole element after repair. Provides a barrier to atmospheric CO₂ (arresting further carbonation) and to chloride ingress. Part of the Renderoc repair system.

A crack-bridging elastomeric acrylic coating for elements where further movement or hairline cracking is expected. Common on ASR-affected structures being monitored, and on façades with a history of thermal cracking.

A three-component epoxy resin mortar for high-strength, chemically resistant reinstatement. Selected where a cementitious repair is inappropriate, thin sections, harsh chemical exposure, or where early strength is critical.

A high-strength, free-flowing micro-concrete for reinstating structural elements where placement space is restricted or the reinforcement is congested. Poured into formwork rather than trowelled.

A two-part, low-viscosity epoxy resin for pressure-injection into fine structural cracks. Restores monolithic behaviour by bonding both faces of the crack and blocking water ingress.

A flexible polyurethane injection resin for cracks that are wet, actively leaking, or subject to minor thermal or shrinkage movement. Reacts on contact with water to form a tough, flexible seal.

A high-tensile stainless steel helical bar bonded into pre-cut slots across a crack, restoring tensile capacity and restraining further movement. Standard product for façade and wall crack stitching.

A high-build acrylic protective coating with enhanced resistance to chloride ion penetration. Specified on coastal, marine and de-icing-salt-exposed structures where a standard anti-carbonation coating isn't enough.
