Product Introduction

Heavy-duty epoxy mortar flooring combines epoxy resin, amine curing agent, pigment and carefully graded quartz aggregate in a dense trowel-applied screed. The aggregate-rich composition carries point loads and resists gouging more effectively than a thin coating, making it suitable beneath heavy carts, mobile equipment and repeated material transfer. A compatible grout or seal coat closes the textured mortar surface where cleanability is critical, while coves and local ramps can be formed from the same mortar family.

Key Features

Graded quartz aggregate creates a compact load-bearing matrix with high resistance to impact and abrasion.

Trowel application accommodates worn concrete, local falls and thicker transitions around equipment bases.

The mortar can be finished with a pore-closing grout and protective topcoat for controlled production areas.

Localized repairs can rebuild damaged edges and ramps without replacing an entire slab section.

Customer Product Concerns

Thin resin films can look intact yet fail quickly when concentrated wheels, dropped tools or damaged concrete impose high mechanical stress.

Small hard wheels crush or gouge a thin coating at turning points.A 3–8 mm aggregate-reinforced epoxy mortar spreads the load through a deeper wearing layer.

Pitted concrete telegraphs through a roller-applied finish.The troweled mortar rebuilds the profile before a grout and seal coat close the surface.

Equipment plinths and ramp edges chip under repeated impact.High-strength epoxy mortar can form dense edge details and bonded local transitions.

An open screed texture retains dirt in a controlled environment.A compatible epoxy grout coat fills surface pores and supports routine mechanical cleaning.

Typical Applications

Heavy cleanroom material-transfer routesEquipment maintenance baysPharmaceutical warehouse aislesProduction areas with loaded cartsPlant rooms and loading thresholds

Technical Parameters

These values represent a typical quartz-filled, trowel-applied epoxy mortar flooring system.

Core Material	Epoxy resin and amine hardener with pigment and selected graded quartz aggregate
Panel Thickness	3.0–8.0 mm troweled mortar system thickness
Effective Width	Typically 1500–3000 mm hand-trowel placement strip width
Maximum Length	Typically up to 10000 mm work section before planned day joints
Steel Facing Thickness	0 mm; the load-bearing facing is epoxy mortar rather than steel
Core Density	Approximately 2100–2200 kg/m³ for the finished quartz-filled screed
Thermal Conductivity	Typically 0.55–0.85 W/(m·K) for dense quartz-filled epoxy mortar
Surface Finish	Troweled matte texture with optional epoxy grout and satin or gloss seal coat
Joint Type	Primer-bonded mortar screed with keyed edges, sealed day joints and retained slab movement joints
Customization	Available based on the intended application and operating environment.
