webercem spray DS
Description

A ready-to-use, polymer-modified, cement-based concrete mix. It contains inert limestone aggregates and dust suppressants. Designed for dry process spray application to give high early strength, reduced rebound and maximise application thickness.

- Uses:

  • Repairs to large areas of structural concrete.
  • Repairs of highway structures: bridge columns, piers, deck soffits, beams, abutments, parapets, retaining walls, tunnels and viaducts.
  • Repairs of marine structures: Jetties, piers, quays, seawalls, concrete offshore platforms, docks and dry docks.
  • Repairs of fire damaged concrete structures.
  • Sealing of mine roadways and tunnels.
  • Structural enhancement of mineshafts.
  • Structural encasement of steel sections, pylons, chimneys, cooling towers.
  • Rock and embankment stabilisation.

- Benefits:

  • Safe to use and handle. Relatively low dust emission, no siliceous aggregates, no caustic accelerators.
  • High-build – up to 150 mm thickness can be applied in one pass on vertical and overhead faces without any additional mesh reinforcement.
  • Rapid strength gain.
  • Low permeability to water and chlorides.
  • Low chloride ion diffusion: better protection of reinforced concrete marine structures.
  • Complies with Highways Agency specifications for repairs to highway structures.

Curing:

Weber.tec ritecure should be used immediately after application unless the surface is to be overcoated or subject to chemical impregnation, which is cured with polythene sheeting and/ or wet hessian.
