Correct period and historical mortar work requires in-depth specialist knowledge. New mortar should always be the best match to the original build. Equally, it should never set/cure harder than the density of the brick itself.
Lime mortar repair and building work ceased shortly after the Second World War. Sadly, cement mortar was predominantly used thereafter, to the detriment of many beautiful properties.
Excessive cement ratios in repair mortars restricted “breathability”, causing internal damp issues. Rebuilding work encouraged strangulation, preventing the building’s natural movement and showing as large fractures through the brickwork.
Finelay Construction are experts in mortar matching. All of our repointing works are performed using type matched mortar that is as close as possible to the original build.
