REPOINTING TRADITIONAL MASONRY
Repointing traditional masonry construction may be necessary for a variety of reasons. It is usually carried out as a measure to prevent dampness or moisture egress in a building due to the decaying of the existing lime mortar which could be hundreds of years old, or if the building has been previously been repointed with a cement based mortar which is usually unsuitable.
Repointing can therefore serve to:
- Exclude rainwater
- Reduce and prevent stone decay
- Stabilise loose masonry
- Improve aesthetic appearance
- Improve breathability within the structure
MASONRY CONSOLIDATION AND STABILISATION
Consolidation repair techniques include deep pack pointing, wall core cavity grouting, underpinning and stitching. Soft capping can be used as an effective technique in preserving ruin from further decay. Consolidation and stabilisation of walls using grouting techniques can be an essential part of a restoration strategy for a building with a deteriorated inner core- this is provided that the original cause of the deteriorated core-water infiltration through decayed joints, cracks, failed roofs/flashings has been addressed.
STONE INDENTING AND REPLACEMENT STONE
When it is necessary to replace a particular stone due to decay or damage, we can cut out the defective stone and source a replacement stone to match the original. Careful consideration will be given to the original craftsmanship, the specification of the finish on both the stone and the joints so that the character of the old masonry is matched and that the new replacement blends in unobtrusively with the existing masonry.
STONE DRESSING AND FIXING
Mid West Lime ltd. can source stone to match the stone in your existing building. We can dress the stone using traditional techniques and fix in place the stones with an appropriate lime mortar mix or in the cases of arches or bridges we can pour a hot lime mix to secure the masonry which was common practice in years gone by.
