M90 CONCRETE REPAIR MORTAR Product
Specifically designed for the repair of concrete.
Jahn M90 Concrete Repair Mortar is a mineral-based, single-component mortar that was developed for the curative and preventative repair of concrete. M90 meets the requirements of the CUR-recommendation 54 – Concrete Repair with manually applied or poured cement-based mortars.
Available in coarse or fine formulations and in a range of standard and custom colours, M90 is suitable for repairing concrete constructions such as bridges, viaducts, tunnels, industrial constructions and houses.
M90 is supplied ready to mix with water and contains no acrylic or latex bonding agents or additives. Being vapour permeable protects the substrate by allowing salts, vapour and water to reach the surface preventing failure due to salt expansion or freeze thaw cycles.
By providing a healthy pH factor with a strong resistance to carbonation, M90 does not allow corrosion to begin. The mortar is able to withstand severe environmental conditions and is not damaged when heavy concentrations of salt crystallisation are present.
Benefits:- Engineered in the lab, proven in the field
- Single component mixes with water only
- Highly moisture, frost and salt resistant and salt and moisture regulating
- Vapour permeable – prevents failure due to salt expansion or freeze/thaw cycles.
- Highly resistant to carbonation
- Single layer build-up – faster and more economical
- Non-shrinking
- Scientifically controlled – no on-site chemistry resulting in product variation
- Can be manually or mechanically applied.
- Strong adhesion – requires no bonding agent
- Water Based: Environmentally and user safe – no solvent clean up or disposal problems
