Lintel failure is very common and the traditional method would be to take the arch or lintel out of situ and rebuild the arch and brick work making this an expensive and time consuming project. Instead of doing that we can come along and provide you with a specification to install a Helical masonry beam which will take the loadings away from the arch and spread them either side as long as its been installed correctly. We can then put some Helical cemties into the arch to stop further movement negating the need to take the arch down and rebuild. A small repair like a 2m wide opening would only take a morning to complete with very little preparation material needed.
This is the expansion and contraction of materials due to change in temperature. Thermal movement varies considerably through the different building materials available and there are many ways to repair such cracks, we can use Helical crack stitches to repair the cracks or if we have a long unbroken block of masonry we can install movement joints to allow the natural movement of the material.
