Fibre-reinforced dry spray structural repair concrete

Jump to:

+44 (0)1525 718877 Website

Application

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 drydocks.
Repairs of fire damaged concrete structures.
Sealing of mine roadways and tunnels.
Structural enhancement of mineshafts.
Structural encasement of steel sections, pylons, chimneys and cooling towers.
Rock and embankment stabilization.
Thin concrete overlays 25–50 mm on columns, beams and soffits.
Increasing cover to steel in RC structures.
webercem spray DSF has been designed for use in both thin and thick sections up to 300 mm.

Description

Fibre-reinfoced dry spray structural repair concrete designed to give high strength, low rebound, low wastage and to maxmise application thickness. Added alkali-resistant glass fibres give higher tensile strength, reduce shrinkage cracking and rebound.

Containing graded inert limestone aggregates and dust suppressants, webercem spray DSF has conformity testing to BS EN 1504-3 and meets the requirements for a Class R4 repair product.

Features and benefits:

Economical - low rebound.
No siliceous aggregates, no caustic accelerators.
High-build - up to 150 mm thickness can be applied in one pass on vertical and overhead surfaces without any additional mesh reinforcement.
Low permeability to water and chlorides.
Low chloride ion diffusion: better protection of reinforced concrete marine structures.
Complies with National Highways specifications for repairs to highway structures.
Fibres provide better strain relief and stress distribution.
Thin overlays 25-50 mm on columns piers and walls without the need for mesh, providing extra cover to steel.
Class 4 repair product meeting the requirements of BS EN 1504-3.
