Thoro® Structurite R4

Thoro® Structurite R4  is a blend of Portland cement, well-graded sand, specially selected fibres and a re-dispersible spray-dried polymer which, when mixed with water, forms a fast-setting, polymer-modified structural repair mortar. It cures to a concrete-grey colour. A specially incorporated Corrosion Inhibitor prevents the offset of corrosion of any embedded reinforcement.

Thoro® Structurite R4  meets the requirements of a class R4 mortar according EN1504-3.
