Structural Repair in Historical Buildings
Where the property is constructed of masonry, there may be signs of structural cracking or instability, failed lintels or ground movement and there are several methods of remedial action which may be undertaken to relieve the problem.
in particular this is using Lateral Restraints or Bespoke Anchor Systems. ‘Crack Stitching’ and ‘Mortar Bed Reinforcement’ are also common remedial measures.
With regards to cavity walls, the Romans were known to use cavity walls in some construction, so this concept is not restricted to modern buildings and should also be considered when defining the repair approach. Furthermore, the property may be of more contemporary design and/or interest. Whatever the case, some form of fixing will have been used between the inner and outer leaves of masonry these may be metallic, brick or slate fixings and a remedial measure without the need for a complete rebuild is usually available and should always be explored.
Timber Resin Repair Systems
Where a structural defect is evident within a major structural/supporting timber beam, again ‘major surgery’ may not be the only option. There are approved systems of sectional replacement of timbers which use a combination of epoxy resin and embedded steel ‘Re-Bar’ within a pre-cut hardwood timber section, which could replace a rotted section of timber (end or middle) without resorting to replacing the complete beam, but which would re-establish the structural integrity of the timber.
