Concrete restoration

Our portfolio of specialist mortars provides solutions to repair and protect concrete. BS EN 1504 Principle 3 is concerned with restoring the original concrete element of the structure to its originally specified shape and function.

Concrete restoration is normally carried out using hand-applied patch repairs, recasting with concrete or applying concrete or mortar by spraying. The scope of BS EN 1504-3 includes materials suitable for structural and non-structural repairs.

Methods of protection based upon the BS EN 1504-3 include applying mortar by hand, recasting concrete, spraying concrete, or replacing elements.
