Watch the video to see the action unfold

Vateris ran structured trials across two Marshalls production lines: wet-cast concrete at the West Lane facility and concrete block paving at St Ives. GypCarb® was tested as a partial cement replacement across both formats, with results independently verified at each stage. Across both trials, results consistently demonstrated significant strength gains, meaningful CO₂ reduction, and near cost-neutral performance, confirming GypCarb® as a viable drop-in solution.

Prove that GypCarb® could deliver measurable strength gains and meaningful carbon reduction across Marshalls’ core concrete product lines without disrupting existing processes or requiring significant cost increases.

Results

Unlocking technical potential

The Marshalls trials confirmed that Vateris’ GypCarb® delivers meaningful strength gains at both early and later ages, while cutting embodied carbon and leaving existing mix designs intact. Results were independently verified across both sites, reinforcing confidence in the consistency and credibility of the findings.

Crucially, the performance held across two distinct product formats: wet-cast concrete at West Lane and concrete block paving at St Ives, demonstrating that GypCarb® is not a single-application solution. For Marshalls, the trials open a clear path toward lower-carbon production across multiple product lines, without trade-offs on performance or cost.
