webercem spray DS

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.
