We don't just "pour and hope." We follow a rigorous building standard to ensure your base remains crack-free and perfectly level for life:
Excavation & Sub-Base: We strip the site and install a compacted DTp Type 1 hardcore base to prevent any ground movement.
Damp Proof Membrane (DPM): We install a heavy-duty plastic membrane to prevent "rising damp" from soaking into your timber or steel structure.
Steel Reinforcement: For larger structures or heavy loads (like hot tubs), we use high-tensile steel mesh (A142) to provide internal strength and prevent cracking.
Laser Leveling: We use precision laser levels to ensure a 100% flat surface—essential for log cabins and modular offices where even a 5mm tilt can ruin the build.

We provide site-specific engineering to ensure your garden structure remains stable, level, and dry for decades.
Garden Office & Studio Foundations We use 1200-gauge Damp Proof Membranes (DPM) and laser-leveling to within a 5mm tolerance. This prevents rising damp and ensures your doors and window frames never warp or stick.
Shed & Workshop Bases Built with reinforced edges to support the concentrated weight of heavy steel or timber units. Our bases elevate your structure, keeping it away from ground moisture and extending its lifespan.
Utility & Infrastructure Bases Fire-compliant, non-combustible platforms designed specifically for oil tanks and heat pumps. These provide a stable, level footprint that meets all environmental and safety standards.
High-Load Leisure Pads A filled hot tub can exceed 2,000kg. We install steel-reinforced, high-PSI slabs designed to manage intense weight without cracking or tilting over time.







Paving flags can shift over time as the ground settles, causing your shed to warp and the doors to misalign. A monolithic concrete base provides a single, solid "raft" that distributes weight evenly and remains stable for decades.
For most standard garden offices, we recommend a thickness of 100mm to 150mm, depending on the weight of the building and the soil conditions. We always include a compacted hardcore base underneath to add further stability.
Yes. We handle the entire process: site excavation, shuttering (the wooden frame that holds the concrete), the pour, and the power-float finish. We leave the site clean, tidy, and ready for your building to be installed.
While concrete "sets" within 24–48 hours, it takes about 7 to 10 days to reach enough strength to support a heavy building. We advise waiting for this curing period to ensure the anchor bolts remain secure.
