Milbank Concrete Products has launched Milbank GDeck – a fully insulated, suspended precast flooring system developed to meet the evolving needs of UK architects, developers, and contractors seeking efficient, low-carbon, and regulation-ready ground floor solutions.
As the construction industry moves toward tighter environmental regulation and heightened performance expectations, Milbank GDeck presents a compelling alternative to traditional beam and block floors. It simplifies detailing, accelerates programme schedules, and supports compliance with both Part L of the Building Regulations and the upcoming Future Homes Standard 2025.
Reimagining the Ground Floor: A Smarter System
Milbank GDeck rethinks the standard suspended ground floor approach by integrating structural and thermal performance into a single system. It combines prestressed concrete T-beams with lightweight, precision-moulded EPS infill panels to deliver a clean, insulated solution that is quick to install and delivers strong thermal performance from day one.
The system forms a continuous insulation layer across the floor, eliminating common cold bridging issues associated with traditional designs. With U-values as low as 0.09 W/m²K (depending on specification), Milbank GDeck enables architects to specify confidently for Part L – and crucially, prepare for the more ambitious energy targets defined by the Future Homes Standard.
Designed for Speed and Safety On Site
Milbank GDeck is not just thermally efficient, it’s also fast and safe to install. The EPS panels weigh under 2kg and are easily cut with hand tools, allowing manual placement without the need for lifting equipment or temporary propping.
A key benefit is the walkable surface created during installation. Once the panels are in place, follow-on trades can access the area immediately – without boarding or curing time. This accelerates sequencing and minimises programme delays, which is a significant advantage for multi-plot residential schemes or commercial sites where speed of build is critical.
Sustainability Built In
With growing pressure on specifiers to address both operational and embodied carbon, Milbank GDeck delivers advantages across the lifecycle. The prestressed concrete beams are manufactured using low-carbon concrete mixes, contributing to an embodied carbon saving of up to 25% compared to traditional reinforced concrete alternatives.
The EPS panels contain 15% recycled content, are fully recyclable, and are manufactured offsite to suit project layouts — reducing on-site waste and improving material efficiency. All deliveries are made using HVO-powered vehicles as standard, further supporting low-emission site strategies.
Fully Supported Specification
Milbank GDeck is backed by a full in-house design service. The Milbank team works with architects, engineers, and developers to ensure layout plans, loading calculations, and thermal detailing align precisely with project objectives and compliance requirements.
Unlike generic beam and block systems, Milbank GDeck is configured to suit individual site and building layouts using a combination of standardised EPS panel sizes. These are then cut on site to suit, offering flexibility without the time and cost associated with bespoke manufacture.
Applications and Compatibility
Milbank GDeck is suitable for a wide range of applications – from single dwellings to multi-unit residential developments, commercial floor slabs, and education or public sector buildings with strict compliance targets.
It is fully compatible with underfloor heating systems, supporting low-temperature heating strategies and helping architects meet future-ready energy specifications — a key consideration for both SAP assessments and decarbonised building services design.
Why Architects Choose Milbank
With over 75 years of experience in precast concrete, Milbank continues to support UK construction with dependable technical support, quality-assured manufacturing, and product innovation.
Milbank GDeck builds on this heritage, delivering a flooring system that answers the core priorities of today’s architects and specifiers — performance, compliance, sustainability, and certainty.
