COULINEX LIANT

COULINEX LIANT is a high-performance injection grout made with natural hydraulic lime (NHL 5) from Saint-Astier, specifically designed for the consolidation and stabilisation of historic and ancient masonry. Free from cement, pozzolans, clinker or synthetic binders, it ensures full compatibility with traditional materials. With its low modulus of elasticity, excellent vapour permeability and strong sulphate resistance, COULINEX LIANT provides a durable and reversible solution for the structural restoration of heritage buildings.

‍

COULINEX LIANT can be used pure for the injection of fine cracks or mixed with sand of various grain sizes for filling larger voids. The recommended aggregates range from 0/0.5 mm for fine work to 0/4 mm for coarse cavities. The maximum sand grain size should be four times smaller than the void to be injected, ensuring proper filling, bonding and long-term stability of the masonry.
