ShrinkGuard™ Crack-Resistant, Low-Shrink Concrete addresses one of concrete's biggest issues: drying shrinkage cracking. This user-friendly advancement reduces shrinkage without special placement or finishing, delivering durable, attractive slabs.
ShrinkGuard™ cuts drying shrinkage by up to 80% at 28 days and 50% in ultimate shrinkage, greatly reducing cracking and curling for high-tolerance surfaces.
Neutral to slight improvement in finishability with no special techniques required.
Allows wider spacing to match column lines, simplifying design and reducing maintenance.
Achieves reductions without construction delays, improving aesthetics and longevity.
Our CBM Concrete Solutions product line covers a wide range of project needs – from self-consolidating and high-workability flatwork mixes to fibre-reinforced, accelerated strength, extended workability, and durability-focused formulations. All mixes are performance-based and CSA-compliant. Our technical team can also develop custom mix designs for projects with specific structural or environmental requirements.
We work directly with engineers and contractors before the first truck arrives – reviewing exposure class, strength development, pumping distances, and workability windows to build a concrete program around your project, not around a standard product. The Gordie Howe International Bridge, the Eglinton Crosstown LRT, and 141 Bay are examples of that process at work.
Yes. Every customer has access to the same ready mix concrete solutions and quality-controlled mixes that go into our largest builds. Get in touch with your local CBM representative to discuss your requirements.
CBM is proud to be part of Votorantim Cimentos, one of the largest building materials companies in the world. Our VC Way is the operating philosophy that runs across the entire Votorantim Cimentos family – and it shapes how our teams work every day. For our customers, that means decisions made close to the job, clear communication from order to delivery, and accountability that does not stop once the truck leaves the plant. The work we did at Ripley’s Aquarium, the Gordie Howe International Bridge, and other countless projects reflects exactly that – sustained technical collaboration, dependable execution, and a standard of care that holds across the full life of a project.
ShrinkGuard™ incorporates an optimized mix design with shrinkage-reducing admixtures (SRAs) that lower the surface tension of pore water, minimizing capillary stresses during drying. This reduces both early-age and ultimate shrinkage by up to 80% at 28 days and 50% overall compared to standard mixes, without relying on special placement or finishing techniques.
ShrinkGuard™’s reduced curling and shrinkage often allows joint spacing to be extended to match column grids, potentially doubling intervals from typical 4.5–6 m to 9–12 m, depending on slab thickness and exposure. Project-specific calculations should use finite element analysis or ACI 360R guidelines, incorporating measured shrinkage values and environmental factors to ensure crack control.
Yes. ShrinkGuard™ exhibits neutral to slightly retarded set times and improved or neutral finishability compared to conventional concrete, supporting conventional screeding, floating, and troweling practices. Compressive and flexural strengths develop normally or better due to the optimized paste structure, making it suitable for high-tolerance floors, overlays, and containment structures.
