Concrete Repairs & Preparation in Townsville & Cairns
CBS Building Group's concrete repair specialists diagnose, prepare and restore concrete structures across North Queensland. From crack injection and spall repair to carbon fibre reinforcement and full-scale concrete restoration.
Concrete Repair & Preparation Specialists
Concrete deterioration is a common challenge in North Queensland's tropical climate — with heat, humidity, cyclonic rain and coastal exposure all accelerating carbonation, corrosion and surface degradation. CBS Building Group has been diagnosing and repairing concrete structures in Townsville and Cairns for over 60 years.
Our concrete repair services range from minor crack injection on a single slab to comprehensive structural restoration of hospitals, bridges and industrial facilities. We are experienced in all aspects of the concrete repair process — from condition assessment and cause-of-failure analysis through to specification, preparation, repair and final protective coating.
We also specialise in concrete surface preparation for coatings and overlays — achieving the correct concrete surface profile (CSP) through diamond grinding, shot blasting or scarifying, critical for the adhesion and performance of any applied system.
Concrete Repair Services
Epoxy Crack Injection
Structural and non-structural cracks injected with low-viscosity epoxy under pressure to restore the monolithic integrity of the concrete element.
Spall & Surface Repair
Repair of delaminated, spalled or deteriorated concrete using specialist repair mortars and polymer-modified compounds. Restored to match existing substrate profile.
Floor Grinding & Preparation
Diamond grinding, scarifying and shot-blasting to prepare concrete substrates for coatings, overlays and adhesive applications to the required CSP profile.
Carbon Fibre Reinforcement
Lightweight structural reinforcement of concrete beams, slabs and roof structures using externally bonded carbon fibre composite systems. An effective alternative to traditional structural solutions.
Concrete Restoration
Comprehensive concrete restoration for buildings, bridges, water retaining structures and infrastructure — from assessment and diagnosis through to repair and protective coating application.
Void Filling & Grouting
Filling of voids, honeycombing and cavities behind or within concrete structures using cementitious or chemical grout systems.
Concrete Repair Project Experience
Our concrete repair team has worked on projects for hospitals, schools, universities, sugar mills, mine sites, water treatment facilities, local councils and defence infrastructure across Townsville, Cairns and regional North Queensland.
