Professional Concrete Wall Crack Repair Services in Singapore

Concrete wall cracks occur due to concrete shrinkage during curing, foundation settlement, thermal expansion and contraction, excessive structural loads, or moisture ingress causing internal steel rebar corrosion. Over time, environmental stressors can widen micro-fissures into deeper structural pathways.

Non-structural cracks are typically thin hairline fractures caused by surface drying and temperature shifts that do not threaten building integrity. Structural cracks are wider (usually over 3mm), run diagonally or vertically through load-bearing walls, and can compromise structural load capacity if not stabilized properly.

For leaking concrete walls, we utilize high-pressure Polyurethane (PU) resin injection. The expanding PU foam penetrates deep into the concrete core, reacting with trapped water to instantly seal water leaks and create a flexible, durable, and waterproof barrier inside the wall.

To restore structural integrity, we perform structural epoxy injection. High-strength epoxy resin is pressure-injected into dry, structural cracks to fuse the separated concrete segments together, restoring the wall's original compressive and tensile strength.

Unsealed concrete cracks allow water and carbon dioxide to reach internal steel reinforcement bars. This causes rebar corrosion, leading to expansion, concrete spalling, structural weakening, and costly emergency restoration if left untreated.

Yes. Our advanced injection techniques (PU grouting and epoxy resin injection) are non-destructive. Ports are placed directly along the crack line to inject repair compounds deep into the structure without noisy wall hacking or demolition.

Standard concrete injection jobs take about 3 to 6 hours depending on the total linear footage and depth of the cracks. Most residential or commercial concrete crack repairs can be completed in a single day with minimal disruption.

Yes. Once injection or patching is finished, surface ports are removed and the area is ground smooth, flush with the concrete wall. We apply fairing coats or protective render so the wall is ready for priming and painting.

Repair pricing depends on crack length, depth, wall accessibility, and whether epoxy structural bonding or PU waterproofing injection is required. We offer free technical site evaluations to provide transparent, upfront quotes.

Yes, all our concrete crack repair and waterproofing services come with a written warranty covering materials and workmanship. If seepage or cracking reoccurs in the treated area within the warranty period, our team will re-inspect and rectify it free of charge.
