  2. 2. Requirement Of The Product For Repairs Of PQC & Expansion Joint1. Flexible enough to accommodate anticipated expansion and contraction – Extreme Climatic Conditions.2. Ultra-violet Resistance – Does Not Become brittle with time.3. Impermeable.4. Excellent bonding with existing concrete and steel.5. Resistance to Tear & Wear6. Fast setting so that repaired patch / Exp. Joint can accept traffic within one hour.7. High Impact & Fatigue Resistance.8. Resistance to all type of fuels, Acid generated from the night soil.9. Noise Reduction and smooth riding quality10. Skid resistance, non-reflective finish, colour matching with concrete, Paintable also.11. Economical – Long Term Maintenance Free Performance.
  3. 3. Delpatch - Elastomeric ConcreteDelpatch is polyurethane basedproprietary chemistry. Compounded to develop high strengthand to promote easy bonding to bothconcrete and steel for high performancepavements. Permanent repair solution Fast Curring - Accept traffic in an hour Self-leveling – Easy Workability.
