High Performance Class R4 Dry Sprayed Micro-Concrete for Large Volume Repairs

Sikacrete-301 Premium (formerly SikaCem-133 S Gunite) is a cement based, polymer modified, one-component repair micro-concrete containing silica fume and high range water-reducing agents, meeting the requirements of EN 1504-3 Class R4. Formulated for machine applications using the dry process without set accelerators, repairs may be profiled and trowel finished easily where necessary.

One component, ready to use.
Non-silica aggregates, so no risk of alkali silica reactivity (ASR).
Easy and quick to set up.
Low rebound losses and dust formation during the spraying process.
High build - 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 easily to a high standard.
Overcoatable with Sika reprofiling / levelling / smoothing mortars and coatings.
EN 1504-3 Class R4.
Low resistivity - can be used with cathodic protection systems.
Suitable for use in contact with potable water.

Usage

Large volume repairs.
Highways works.
Bridges (columns, piers, sofits, beams, parapets, abutments, etc.).
Marine structures (quays, piers, jetties, sea walls, docks, dry docks, marinas, offshore platforms, cofferdams, caissons, etc.).
Water facilities (reservoirs, dams, tanks, buildings, treatment works, etc.).
Tunnels.
Faςades.
For exterior and interior use.
In place of Class R1, R2 and R3 mortars.
Low resistivity - can be used with cathodic protection systems.
