Superior Injectable Epoxy for Oil-Soaked and Wet Crack Repair

ZDS-2002AB is a high-performance, injectable epoxy repair system designed specifically for challenging structural repairs in construction. Engineered to address oil-soaked or wet concrete cracks, this grey epoxy offers outstanding moisture and oil resistance, maintaining stability even in high-humidity environments. Its low viscosity—ranging from 8000 to 12000 cps—enables deep penetration and effective sealing of very fine cracks, down to 0.02 mm, ensuring robust reinforcement for concrete structures.

This innovative repair system delivers a rapid cure and high hardness of 80-90 Shore D, making it ideal for time-sensitive projects that demand quick turnaround and minimal downtime. ZDS-2002AB’s formulation creates a durable bond with concrete, reinforcing structural integrity while preventing further damage from moisture ingress and oil contamination.

Moisture-resistant, oil-resistant, Suitable for fine cracks, Remains stable in high humidity, Low viscosity for deep penetration

Clean the crack surface thoroughly to remove debris or contaminants. Inject ZDS-2002AB epoxy using a suitable injection system targeting the crack depth and width. Allow the product to flow and fill the crack thoroughly. Remove excess epoxy from the surface, if necessary. Allow curing for 24 hours at 25°C. After full cure, the substrate can be back in service or receive further finishing if required.

  • Repair of oil-contaminated or wet concrete cracks
  • Very fine crack injection (≥0.02 mm)
  • Permanent repairs in high-humidity or submerged environments
  • Restoring structural integrity of concrete beams, slabs, columns
