System Buildup:

High Movement Joint Repair

System Description:

This high-movement joint repair system consists of a low-viscosity polyurethane primer, which ensures deep penetration and strong adhesion on both porous and non-porous substrates. This is followed by a moisture-curing, non-sag elastomeric polyurethane sealant that provides long-term elasticity and high mechanical resistance. The system is completed with a waterproofing, carbonation-resistant acrylic coating, applied at high film thickness to bridge cracks up to 100 microns and deliver durable protection against water ingress and harsh weather conditions.

System Key Features:

  1. High-movement repair system offering durable waterproof protection for demanding applications.
  2. Superior adhesion to porous and non-porous substrates with strong bonding between old and new concrete.
  3. Flexible system that accommodates structural movement and resists carbonation, mold, and mildew for long-term protection.
