Lime Mortar

Lime mortar is used in traditional solid wall buildings to allow moisture to escape. Cement mortars are not used in these old buildings because they trap moisture in the wall which leads to decay and spalled bricks.

A repair specification should take into account the strength, colour and texture of the original material along with site conditions and exposure. We can advise on suitable mortars that are compatible to your building.

There are two options


Heritage Mortar

A preblended lime mortar made with local sands to produce pale yellow or off-white coloured mortars made with lime putty or as a hot mixed lime mortar.


Natural Mortar

A preblended lime mortar in a large range of colours made with natural hydraulic lime.
