Available in a range of strengths for consolidation and void filling of solid masonry, Cornerstone Conservation Grout is supplied as a single component dry-bagged product, mixed with water on site to create a high stability, fluid grout that can be both pumped and gravity poured. A 12.5kg bag will produce 15-20L, depending on the water addition rate.

Cornerstone Conservation Grouts can be made to suit most historic masonry and conditions. They are factory blended using St. Astier NHL, Silica and Clays, combined with carefully selected additives to improve the grouts physical and mechanical properties. Cornerstone Conservation Grouts are free from cement.
