Neorep – Repairing mortar

Introduce

Description

High strength, thixotropic, non-shrinking, fiber-reinforced repairing mortar

Fields of Application

• Thanks tο its special composition and remarkable mechanical properties Neorep® is suitable for easy and highly durable restoration jobs in buildings without formworks.
• Some indicative uses are repairs of damaged, cracked or broken concrete elements (e.g. columns, beams, slabs, stairs, holes of hairpin bends), doors, windows (frames, bases), cracks and joints on concrete, rigid joints used for pre-cast, industrial flooring, visible reinforcements and concrete pipes.

Properties/Advantages

• Neorep® is a non-shrinking ready to use premixed mortar of high
  thixotropy.
• Its aggregates of selected particle size and special additives prevent any cracking attributed to non-ideal curing conditions such as plastic shrinkage or vibrations (e.g. due to noise and traffic of vehicles.
• It shows quick and easy laying and finish.
• Neorep® possesses modulus of elasticity and coefficient of thermal, which grants excellent compatibility with concrete elements.
• It has great resistance to the attack of chemical agents such as chlorides (defrosting salt, sea water, etc.), sulphate, acid rain, carbon dioxide.
• Neorep® meets the requirements of Class R4 of EN 1504-3.
