Application

  • High strength repairs to pavement concrete both thin-bed and full-depth.
  • Thin-bonded repairs 25–75 mm depth.
  • Industrial floors or failed floor slabs.
  • Parking decks and ramps.
  • Bridge deck repairs.
  • Jetty decks and slipways to coastal areas.
  • Loading bays.
  • Airport hardstandings.
  • Repairs to steps and joints.

Description

webercem pyratop is a two-part hydraulic cement based repair concrete consisting of a bag of the product and a smaller bag of special aggregate. When mixed together with the addition of water, it produces a rapid setting concrete with high early strength suitable for thin-bonded toppings or full-depth repairs up to 15 m². It is dimensionally stable and has excellent abrasion resistance due to the use of hard granite aggregate.


Features and benefits:

  • Complies with Highways Agency Specification HD27/04.
  • 25–30 minute working time at 20°C.
  • 45 minute set time at 20°C.
  • Traffickable in 6 hours at 20°C and 18 hours at 10°C.
  • Shrinkage compensated.
  • Resistant to freeze/thaw conditions.
  • Can be used for winter work down to 5°C.
  • Excellent abrasion resistance.
  • May be extended with non-reactive 10 mm granite aggregate for full depth repairs over 75 mm depth.
  • Excellent strength gain after 6 hours at low temperatures.
  • No special bonding agent required.
  • Requires only the addition of water.
