Cornerstone Low Strength Masonry Grout is a dry ready mixed lime grout designed for pumping, pouring, or needle injecting into solid-walled masonry to effectively fill gaps, spaces or cavities.

Engineered with precision, using 100% pure natural hydraulic lime, graded powdered mineral fillers and conservation-appropriate additives to create high-flow grout with all of the virtues of a pure Natural Hydraulic Lime grout. Available as standard with Saint-Astier® NHL2. Other binders and mix ratios are available upon request.

Well-suited for projects looking for a balanced approach between strength and breathability.

– A fine texture helps to fill the smallest of gaps
– Supports stability without excessive strength
– High-flow eliminates segregation and blockages
– Ensures a durable and resilient bond
– High porosity for improved moisture management
– Flexibility helps accommodate building movement
– Aids in combating water penetration
– Helps prevent water pooling inside masonry

Suitable for void filling and consolidation of masonry walls, where the binder strength is appropriate for the host background or surface. Not suitable as a tiling or floor grout.

Low Masonry Grout is ideal for repairing, reinforcing, and filling voids in solid masonry. Appropriate for various project types, including conservation, renovation, or sustainable construction.
