R4 Dry Sprayed Micro Repair Concrete

SikaCem -133S Gunite ( formerly SikaCem -133 Gunite) is a cement based, polymer modified one component repair mortar containing silica fume and high range water-reducing agents, meeting the requirements of Class R4 of BS EN 1504-3. Formulated for machine applications using the dry process without set accelerators, repairs may be profiled and trowel finished where necessary.

One component, ready to use micro concrete
Non silica aggregates
Low rebound losses and dust formation during the spraying process
Layer thicknesses in one application overhead up to 150mm are possible without any additional mesh reinforcement
Rapid strength gain without set accelerators
Very low shrinkage
Can be finished to a high standard
Overcoatable with Sika reprofiling/levelling mortars and coatings

Usage

Large volume repairs
Bridges
Marine structures
Tunnels
Facades
For exterior and interior use
In place of R1, R2 & R3 mortars
