Our Process

Consultation and Assessment - We work closely with engineers, contractors, designers and project managers to understand project and material requirements via site surveys and pre-start meetings.
Mix Design - a mix design is produced for approval, tailored to the client's specifications.
RAMS - we produce site-specific Risk Assessments and Method Statements for approval to ensure all works are completed safely and successfully.
Pipework - we can install sacrificial pipework on your project, saving you time and ensuring an optimal infill solution.
Manufacture and Production - Foam concrete mixes are manufactured on site using our foam generators and are tailored to meet specific density, strength, and flow criteria.
Delivery and Placement - Material is manufactured and placed efficiently with or without our specialist concrete pumps, ensuring consistent quality with minimal site disruption.
Quality Control - All foam concrete is produced under strict ISO 9001 quality standards to ensure reliable performance. We offer independent UKAS accredited cube testing.
Project support - We offer dedicated project support from planning through to completion.
Documentation support - Assisting with site records, compliance reporting, and handover files
