Analytical design and chemical pouring of thick prestressed concrete monolithic floors engineered to support high-tonnage gantry cranes and rotating heavy machinery.
Straightforward answers about prestressed concrete slabs, chemical pours, and heavy machinery foundations.
We design and pour slabs between 250 mm and 350 mm thick for gantry cranes in that range. The exact depth depends on the crane's wheel loads, the soil bearing capacity, and the required reinforcement layout. We always run a full structural analysis before the pour.
We use post-tensioning tendons placed in a grid pattern to keep the slab in compression. The concrete mix includes shrinkage-reducing admixtures and a low water-to-cement ratio. We also control the curing temperature for the first 72 hours to minimize thermal stress.
Yes. We formulate a mix with silica fume, corrosion inhibitors, and a low permeability design. For floors exposed to aggressive chemicals, we also apply a densifier and a chemical-resistant sealer after curing. The slab is tested for surface absorption before handover.
From design approval to finished pour, a standard 300 m² slab takes 4 to 6 weeks. This includes soil testing, structural engineering, tendon layout, concrete mixing trials, and the pour itself. Curing and testing add another 7 to 10 days before the machinery can be installed.
Yes. We design the slab with tuned mass dampers and isolation joints that decouple the foundation from the surrounding floor. The concrete mix is adjusted for higher damping capacity. We measure vibration levels before and after installation to verify the design targets.
We provide a 10-year structural warranty on all prestressed slabs we design and pour. The warranty covers material defects, excessive cracking, and load-bearing capacity. Routine maintenance and chemical exposure beyond the specified resistance are not covered.
Post-tensioned concrete eliminates the weak points found in jointed floors. A single continuous pour with high-density reinforcement handles dynamic crane loads and rotating machinery without settlement or cracking.
Every saw-cut joint is a potential failure line under heavy point loads. A monolithic pour removes those lines entirely, distributing stress across the full slab area. Gantry cranes running on rails stay level within 1 mm tolerance over the entire bay.
Standard ready-mix concrete cannot resist the combination of high pH fluids, thermal cycling, and 50-ton wheel loads. We design the binder, aggregate gradation, and admixture package for each pour. Silica fume and corrosion inhibitors are added when the process requires chemical resistance.
Unstressed slabs creep and curl over time, especially under rotating machinery that generates constant vibration. Post-tensioned cables compress the concrete, keeping the surface flat and preventing micro-cracks from propagating. The result is a floor that stays within spec for decades.
Cold joints are the most common cause of delamination and water ingress in industrial floors. We schedule the pour as a single continuous operation with backup pumps and on-site batch plant coordination. No breaks, no second lifts, no hidden planes of weakness.
Rotating machinery transmits low-frequency vibration through the foundation into adjacent equipment and structures. We embed isolation joints and tuned mass dampers directly into the monolithic pour, decoupling the machine base from the rest of the floor without adding separate pads.
Every slab is surveyed for flatness, elevation, and reinforcement cover before concrete arrives. After curing, we run a full load test with the client’s crane or machinery to confirm deflection stays within the design envelope. The data is handed over as part of the as-built documentation.
