Factory / manufacturing plant

Factories need floors that take forklifts, machines that sit level on their bases, and protection where chemicals are used. Downtime is expensive, so cure times matter as much as the products.

Factory shed cut open to show a machine on a concrete plinth, with the grout layer under its base plate in orange

What this project needs, step by step

Footing, column and plinth beam in soil, all buried faces coated, with a damp-proof layer under the brick wall. Foundations, footings and plinth Protect footings, column stubs and plinth beams against groundwater and aggressive soil, and stop damp rising into the walls above. This is done during construction, before backfilling. 6 steps Motor and pump on a steel bedplate, bedded on grout over a concrete block with bolts set in grouted pockets. Machine foundations & equipment bedding Generators, compressors, presses, pumps and turbines need a foundation that carries vibration and impact without loosening. The usual build-up is engineered concrete, anchored or grouted holding-down bolts, and a high-strength non-shrink bedding grout. 7 steps Steel column base plate with grout poured from a raised box on one side, flowing fully underneath to the far side. Base plate & bearing grouting Steel columns, bridge bearings and equipment sit on a layer of non-shrink grout that carries the load into the foundation. Choose the grout by gap depth, mix it with only the specified water, and pour it continuously from one side. 7 steps Existing concrete with resin-filled drilled holes holding new steel bars and a threaded rod fixing a steel plate. Chemical anchors, rebar & dowels Chemical anchors fix bolts, threaded rods and new reinforcement bars into existing concrete or masonry for extensions, railings, machines and services. Load capacity depends on the design, hole cleaning and base material, so safety-critical work needs an engineer. 7 steps Fresh concrete slab with hardener powder scattered and power-trowelled into a hard top skin, and a sealed saw-cut joint. Warehouse floor hardeners (dry-shake) New warehouse and factory slabs get a hard, dust-free wearing surface when a dry-shake hardener is trowelled into the fresh concrete and cured straight away. Existing dusty slabs can be densified with a liquid hardener. 7 steps Floor section: concrete slab, primer, thick epoxy layer and a top coat being rolled on, with a sealed floor joint. Epoxy industrial floors Epoxy floors give factories, warehouses, workshops and labs a seamless, dust-free and easy-to-clean surface. Success depends on a strong, dry slab, mechanical preparation and a trained applicator. 7 steps Floor section: flexible polyurethane floor over primer, coved up the wall and bridging a hairline crack in the slab. Polyurethane & elastic floors Polyurethane floors are tougher and more flexible than epoxy, can bridge fine cracks and, with the right seal coat, resist UV. Use them on crack-prone slabs, for comfortable decorative interiors, on balconies, and as PU-cement screeds where heavy wear and heat occur. 7 steps Floor joint with steel edge angles and orange sealant over a foam rod, and a heavy wheel rolling towards it Floor joints in car parks, warehouses and roads Saw-cut, expansion and connection joints in floors that carry people, cars, forklifts or trucks. The sealant must take both traffic and movement, and the joint must be sized for it. 6 steps Concrete sump in the ground with a continuous protective lining inside, holding liquid fed by a dripping pipe. Chemical-resistant protection (tanks, bunds, sewage) Linings and coatings that protect concrete and steel from acids, sewage gases, fuels and industrial chemicals in treatment plants, chemical tanks, bunds and manholes. The coating is chosen for the actual chemicals, concentrations and temperatures, on a strong, prepared substrate. 7 steps Flat roof section with an exposed coating on the slab, turned up and over the parapets and into the drain outlet. Exposed roof waterproofing A liquid-applied membrane that stays open to sun and rain on a flat or sloped concrete roof (chhat). Use it on a new roof once the slab is 28 days old, or to refurbish a leaking roof before the monsoon. 6 steps Concrete beam with a square cut-out repair: cleaned steel bars coated, and repair mortar being trowelled in flush. Spalling concrete (chhajja, balcony, beam, column) Concrete that cracks, bulges and falls away, usually with rusty steel behind it, on chhajjas, balcony slabs, beams, columns and tank slabs. This guide follows the EN 1504 sequence: remove, protect the steel, rebuild, seal and protect. 7 steps Joint between two wall sections sealed on both faces with orange fire-rated sealant, with flames on one side Fire-rated joints Joints in fire-rated walls and floors, such as stair and lift shafts, compartment walls and plant rooms, must hold back fire and smoke for the rated time. The rating comes from a tested configuration, not from the sealant alone. 6 steps
