In some instances damage to exterior walls may be more
substantial and merely grinding out cracks and filling them with sealants will not suffice. Reports from Structural Engineers or Building Surveyors often recommend (assuming the damage is not so bad
as to need underpinning) the stabilisation of external wall cracks using steel helibar fixings and/or the insertion of expansion and movement joints. This form of 'crack stitching' using steel bars
inserted in to a bonding resin, usually within the mortar joints in brickwork, has proven a very reliable and permanent solution to stubborn and larger wall cracks.
In some instances exterior wall cracks are more severe and can often run vertically from ground level to much
higher up the wall. In these cases merely filling the crack is simply not sufficient as the crack develops not only through the outer layers of render but also deeper in to the brick, stone or block
The insertion of horizontally placed 'helical' steel bars
helps to strengthen the wall and provide enhanced stability.
The 'helical' steel bars are then encased in resin and, once the resin dries, are coated over to completely
disguise the repair and leaving the wall in the chosen unblemished decorative finish.
Durcan Services are experts in the installation of such remedial systems and subsequent 'making good' of the wall surface to achieve a decoratively superb finish.
Durcan Services provide a full or partial re-pointing service. It is recommended that following re-pointing the
bricks and mortar are coated with a clear silicon coating to further protect them from on-going weathering and penetrating damp.
Please note: We always recommend the commissioning of a Structural Report in cases where severe cracks have
appeared in exterior walls.
