Description
Hard-Wearing, Non-Shrink, Rapid Cure, Repair Mortar
Single-component, fast-setting, Portland cement-based structural mortar, used primarily for the durable repair of concrete. Ideal for roads, runways, bridges, decks, floors and footpaths.
Polymer-modified, and fibre-reinforced, HydroSeal 203-RM is physically and chemically compatible with the host concrete, quickly exhibiting high adhesive and compressive strength.
As a single component, requiring only the addition of water, the resulting mortar is rapid curing with enhanced polymeric properties and reliable strength development which is not significantly affected by low temperature use. The mortar can be used as supplied up to 100mm deep, or bulked out with clean, washed, sharp sand to form a high-performance screed or for floor or deck repairs up to a maximum depth of 300mm.
Key Benefits
- Incorporates the latest cement chemistry, fibre and styrene acrylic copolymer technology
- Reliable strength development, even at sub-zero temperatures, gives rapid return to service
- Prepackaged material only requires mixing with clean water. Can be bulked out with sand or aggregate
- High bond strength exceeds tensile strength of concrete
- Sets in 10 minutes at 20°C yielding a durable, high strength mortar
- Dense matrix resists 10 bar water pressure
- Very high diffusion resistance to acid gases and chloride ions
- Sulphate resistance to class DS-5/5m of BRE Special Digest 1 and ideally suited for sewage and wastewater applications
- Non-toxic when cured and is listed as authorised under Regulation 31 for use in the supply of potable drinking water
- Economic mortar requiring no substrate or inter-layer priming. Part bags can be mixed
