Epoxy-based flexible concrete for expansion joint repair, asphalt crack sealing, and pavement defect patching. Fast-setting, high-strength, and durable solution.
●Fast curing epoxy elastic concrete for quick traffic reopening
●Superior adhesion and chemical resistance compared to polyurethane-based materials
●High flexibility with excellent tensile strength and crack resistance
●Multi-substrate bonding for concrete, asphalt, steel, and more
Product Introduction
Elastic Concrete is a high-performance, epoxy-based polymer concrete composed of three parts:
Component A: Elastic epoxy resin
Component B: Toughened epoxy hardener
Component C: Specially-graded high-performance aggregate
Unlike traditional polyurethane-based flexible concretes, this epoxy formulation offers superior adhesion, mechanical strength, and chemical durability, making it ideal for structural repairs in extreme conditions such as highways, rail tracks, bridge joints, and airport runways.
