Warehouse and forklift flooring: specification guide
A warehouse floor is a working surface for people, pallet jacks and forklifts. The hardest wear may be a few square metres at a charging bay, a tight turn, a dock or a racking aisle rather than the whole building. Good specification starts by mapping those duties, assessing the concrete and deciding what the finished floor must do. A resin system can reduce dust and simplify cleaning, but it cannot repair a structurally failing slab or replace a traffic management plan.
Map the traffic before selecting a coating
Record the type and frequency of vehicles, loaded weights, tyre materials, wheel diameters and turning patterns. Small hard wheels and repeated steering can concentrate abrasion at local points. Note pallet drops, scraping, battery charging, leaks, washdown and sun at open doors. Include the height and condition of joints, the movement of racks, and whether a floor must support clean storage, food packaging or a specialised controlled environment. A smooth, attractive coating can be appropriate in one aisle and unsuitable for a wet dock or an oil-contaminated service corner.
Compare the ALKA pathways against the actual duty
ALKA publishes ALKA-902 as a general-purpose epoxy build over prepared concrete, with ALKA-100 primer and ALKA-110 body and finish coats. ALKA-901 uses a compatible primer and self-levelling epoxy body, and ALKA lists warehousing and industrial traffic among its intended applications. The selected thickness, substrate acceptance, finish and any aggregate need to be written into the project schedule using current product data.
| Zone or duty | Pathway to assess | Questions before specification |
|---|---|---|
| General storage and pedestrian circulation | ALKA-902 epoxy | Existing slab, cleaning, wheeled loads, desired finish and pedestrian traction. |
| Busy aisles and controlled production | ALKA-901 self-levelling epoxy | Tyre contact, turning abrasion, joint condition, profile, cleanliness and service interruptions. |
| Dock edges, tight turns and charging areas | Local design and product review | Impact, concentrated wear, battery or other chemicals, moisture and protected edges. |
| Outdoor or sun-exposed threshold | UV-suitable finish or separate build | Exposure, rain entry, thermal movement and compatibility of every layer. |
The table does not imply that an epoxy floor is resistant to every spill or that a topcoat will strengthen weak concrete. Obtain a chemical schedule for battery electrolytes, oils and cleaners where relevant. Include concentration, temperature, duration and cleanup method. The full coating system must be assessed for each exposure.
Inspect and prepare the concrete
Check for dusting, laitance, old sealers, oil penetration, soft repairs, cracks, hollow areas and moisture sources. A coating needs sound concrete with the surface profile and cleanliness specified for the selected primer. Mechanical preparation may expose more defects than a walk-through suggests. Agree which joints remain active, which spalls will be rebuilt and how transitions to adjacent floors will be made. A resin overlay follows the support beneath it; repairing visible cracks without addressing movement or contamination can simply shift the failure to the coating edge.
Joints, racks and wheels
Forklift traffic can strike raised joint arrises and poorly supported patch edges. Review joints at racking rows, dock approaches and turning circles separately. Structural and movement joints need a designed detail that allows their intended movement. The floor specification should include edges, drainage channels and penetrations as well as open-field coating. Confirm whether racks will be installed before or after coating and how anchors or later alterations will be sealed.
Moisture and timing
Use a defined substrate moisture assessment and record temperature, humidity and condensation risk before application. Old slab history matters: groundwater, washdown, wet cleaning or rain at doors may change the suitable primer or system. Agree the necessary curing stage for pedestrians, pallet jacks, forklifts, cleaning and chemical exposure. A surface feeling hard to touch is not proof that it is ready for a loaded truck.
Build floor markings into a wider traffic plan
Safe Work Australia’s warehousing traffic guide says the best way to minimise forklift injury risk is to separate pedestrians and forklifts. It discusses barriers, marked pedestrian paths, exclusion zones, speed controls, dock lines and a documented traffic management plan. Coloured resin and line markings can make routes visible, but paint alone is not a substitute for physical separation, sight lines, suitable lighting, safe procedures and worker training.
Coordinate the floor finish and markings with the actual traffic layout. Mark pedestrian routes, crossing points, keep-clear areas and charging stations only after the operator confirms their locations. Plan how markings will be maintained when aisles or racking move. Safe Work Australia’s slip and trip guidance also recommends suitable floor coverings, drainage and prompt spill cleaning. Select and, where specified, test traction for the real dry or wet use of each zone. Rougher texture can increase cleaning effort, so trial the finish with site equipment.
Specify a verifiable installation and handover
A useful quotation identifies zones and exclusions, repairs, preparation method, test results, chosen primer, body and finish, joint details, texture sample, marking layout and return-to-service stages. Agree inspection points before coating hides repairs and joints. Record batch numbers, application conditions and the agreed checks for coverage, thickness or adhesion. The operator needs the final cleaning method, spill response and an inspection plan for worn turns, dock edges and damaged sealants.
Send ALKA the floor plan, photographs, substrate age and condition, forklift and pallet-jack details, loaded weights, tyre type, annual traffic pattern, chemical list and preferred shutdown window. Request a project-specific system review and check the current verified TDS for each selected product before ordering or application.
Warehouse flooring questions
Is a thicker coating always the better warehouse floor?
No. The slab, preparation, tyre contact, turning and joint details all affect performance. Select a complete build for each zone rather than judging by nominal thickness alone.
Can epoxy line marking keep pedestrians safe from forklifts?
Markings help communicate routes, but Safe Work Australia prioritises separating people from forklifts. Barriers, exclusion zones, lighting, procedures and a traffic plan may be needed.
Can coating cover an uneven, oil-contaminated slab?
That is not a reliable starting point. Assess contamination, structural condition and levels first; prepare and repair the slab under an approved schedule. The coating does not correct a weak substrate.
When can forklifts return after installation?
Follow the selected product and system’s approved cure schedule at actual site conditions. Pedestrian readiness and loaded vehicle or chemical service can have different release points.
