MasterEmaco S 420

Rapid-setting high-strength structural repair mortar

Structural concrete repairs in areas in contact with potable water need a high-strength mortar designed for the job. In short, that means it must be Regulation 31-approved, as well as possessing all the right performance characteristics. MasterEmaco S 420 is a rapid-setting polymer-modified repair mortar designed to meet these demands exactly.

Where can MasterEmaco S 420 be used?

MasterEmaco S 420 is suitable for structural repairs of reinforced and non-reinforced concrete, especially where high compressive strengths are required. It’s ideal for repairing damage caused by:

Corrosion of reinforcement bars
Alkali aggregate reaction
Impact damage

The mortar can be applied in layers of 10-50mm.

What are the benefits of MasterEmaco S 420?

MasterEmaco S 420 removes the need for separate primers and bonding coats, saving a lot of time by enabling a complete repair in a single operation. Its rapid-setting qualities result in high production rates, reducing access and labour costs.

Delivering high performance for extreme durability and protection of embedded reinforcement, MasterEmaco S 420 is Regulation 31-approved for contact with potable water after just three days’ curing.
