Environmentally, the manufacture of limes or Natural Hydraulic Limes (NHLs) consumes less energy and produces less greenhouse gases than that of Portland cement per unit weight.*
Lime-based mortars offer a range of advantages from a design perspective.
Walls have improved ‘breathability’ to water and water-vapour, which reduces the likelihood of frost failure of materials and thus improves the internal living environment.
Walls have more tolerance to movement caused by thermal and moisture action.
Lime-based mortars are capable of self-healing microscopic cracks by plastic flow and diffusion and are less susceptible to sulphate attack, providing all-round consistently high-quality results.
The SMET Professional range of quality NHL-based mortars is backed up with the expertise of an on-call technical advisor.
