LIME RE POINTING & LIME RENDERING
Many older properties were built without a damp proof course. They were
constructed in such a way that allows moisture to both enter and leave the materials
the opposite of modern construction techniques and materials that are sealed against moisture. Older properties are unable to breathe they can suffer from damp problems causing mould, fungi, dry and wet rot.
DAMAGE TO SOFT BRICKS WHEN USING
HARD DENSE CEMENT MORTAR WHEN REPOINTING.
PENETRATING RAIN SOAKS THE SOFT PORUS BRICK
AND THE CEMENT POINTING STOPS THE MOISTURE
FROM ESCAPING AND THIS IS THE RESULT
Most pre- 1930 buildings were built with lime and should therefore ideally be pointed
with lime , cement pointing is very hard and because of its lack of flexibility it will crack
over time when used in old properties , as the walls move and try to breathe
Once cement pointing cracks it allows water to get into the structure of the building
without letting it escape again or evaporate this leads to damp problems
We have plenty of experience in removing cement pointing and replacing with lime
It is a job that must be done with great care ,so the other building materials such as
brick or stone are not damaged.
