MMC Due Diligence & Class A1 Building Systems
Modern Methods of Construction (MMC) deliver zero-carbon living only when engineering integrity, structural fire performance, and warranty clearances are mathematically proven before ground is broken.
Market Catalyst curates the commercial and technical data repository for Dragonboard magnesium sulphate (MgSO₄) stabilized composite Structural Insulated Panels (SIPs)—formulated with MgO, water, perlite, wood fibre, and bamboo fibre—providing architects, institutional funders, local authorities, and principal contractors with complete, unredacted test reports from Warringtonfire, FPA, BRE, Stroma, and UK accredited laboratories.
Certified BS EN 13501-1 Class A1 non-combustible facings combined with 198-minute loaded fire endurance (BS EN 1365-1) and FPA cladding test verification.
Achieves 0.12 W/m²K thermal transmittance and superior airtightness—proven in certified SAP 10 BREL compliance assessments and EPC Band A deployments.
Eurocode 5 structural testing validates axial and shear load-bearing capacity for residential multi-storey envelopes (demonstrated at Parkside Place 5-storey build).

Decarbonised Ground-to-Roof MMC Solutions
Eliminating on-site wet masonry, long cure cycles, and corrosion vulnerabilities. Deploying high-performance mineral composites from subterranean foundations to Euroclass A1 wall assemblies across residential master plans and marine modular structures.
High-Volume Offsite Party Wall Integration
Engaged in direct offsite specification for major residential developer programmes—including architectural detailing with Mattamy Homes and Q4A Architects for 2-hour non-combustible party wall fire separations across high-density townhouse schemes, eliminating traditional masonry cavity blockwork.
Marine & Modular Monocoque FabricationCross-Sector Transfer: Terrestrial to Marine
The same rot-proof, impermeable, and non-combustible composite mechanics proven in residential party walls scale seamlessly into marine monocoques, floating platforms, and flood-resilient civil infrastructure.
Advanced Mineral-Composite Substructure Systems
Engineered to replace carbon-intensive precast concrete in Modern Methods of Construction. By combining non-metallic mineral reinforcement with an impermeable, high-circularity matrix, this solution delivers rot-proof, zero-corrosion ground foundations with substantial deadweight savings.
Zero Steel Corrosion: Mineral rebar eliminates rust-jacking, carbonation loss, and concrete degradation in wet ground conditions.
Diverted Circular Streams: High-density matrix incorporates up to 85% diverted mineral by-products, directly supporting Net Zero carbon targets.
Logistical Efficiency: Up to 25% lighter than standard precast beams, reducing crane capacity requirements and road freight emissions.
Verified Testing & Institutional Standards Matrix
Evaluated against the stringent performance criteria of the British Board of Agrément (BBA), Building Research Establishment (BRE), and UK building warranty frameworks.
