Self-Levelling Epoxy
Specification-grade self-levelling epoxy delivering FF35-FF75 floor flatness for warehouses, distribution centres, large-format logistics installations.
What is Self-Levelling Epoxy?
Self-levelling epoxy is a low-viscosity, two-component resin system engineered to flow across prepared concrete substrates and cure to a seamless, optically flat monolithic surface. Under gravity and controlled application conditions, the material self-distributes to floor flatness classifications between FF35 and FF75 — tolerances that satisfy the operational demands of automated racking systems, narrow-aisle forklifts, and precision logistics conveyors.
Facility managers, structural engineers, and procurement officers at distribution centres, cold-store facilities, and large-format warehouses specify self-levelling epoxy when the substrate must perform as a precision instrument — not merely a walking surface. It is the specification of choice wherever VNA (Very Narrow Aisle) operations, AS/RS installations, or pharmaceutical cold-chain logistics set non-negotiable flatness criteria.
When to Specify Self-Levelling Epoxy
Self-levelling systems are the authoritative answer for high-bay warehouses, bonded logistics halls, and manufacturing environments where even marginal floor deviation translates into operational downtime or racking instability. Distribution centres processing high-volume throughput, food-and-beverage processing floors requiring hygienic seamless surfaces, and automotive component facilities demanding chemical-resistant walking areas all sit within the natural specification envelope of this system.
Beyond logistics, public infrastructure procurement teams — port authority warehouses, airport cargo terminals, and pharmaceutical manufacturing facilities — routinely specify FF50+ floor classifications as a minimum performance threshold. Self-levelling epoxy delivers within that envelope with documented, inspectable precision.
Methodology — The Epoxy GH Specialist Approach
-
Specification Review & Substrate Assessment. Our specialists review the structural engineer’s flatness specification and FF/FL classification targets before a single litre of material is ordered. Slab age, moisture vapour emission rate (MVER), and existing surface profile are recorded against project tolerances.
-
Surface Preparation — Mechanical Profiling. Diamond grinding or shot-blasting is executed to achieve a CSP 3–5 surface profile per ICRI Technical Guideline 310.2. Laitance, contamination, and previous coatings are fully removed to ensure substrate bond integrity.
-
Priming & Crack Remediation. A low-viscosity penetrating primer is applied by roller to seal porosity and inhibit outgassing. Active cracks are chased, filled with semi-rigid polyurethane joint compound, and allowed to cure before pour commencement.
-
Material Mixing & Pour Execution. Resin and hardener are combined at factory-set ratios under timed, variable-speed mechanical mixing. Pours are executed in calibrated bays using gauge rakes and spiked rollers to release entrapped air — maintaining continuous wet-edge contact to eliminate cold-joints.
-
Flatness Verification & Quality Sign-Off. Post-cure, FF/FL readings are taken across the slab using a digital F-number profileograph. Results are documented in a written floor flatness certificate issued to the client before practical completion is declared.
