Many structural problems result from a change in the local environment such as damage from the roots of trees and shrubs or subsidence and heave resulting from a change in the ground conditions.
Rot is another major cause of structural faults as over time it can weaken the roof support timbers, lintels and floor joists. Occasionally a structural fault may be caused by human error such as a flaw in the architects design or the method of construction used by a builder. Materials used in a building such as lintels or steel can also occasionally be faulty and cause structural damage.
In all scenarios it pays to be covered with a structural insurance provider as repairs to the structure of a building can prove to be very expensive.
Here we look at some of the most common structural issues and their remedies.
There can be a few different causes of a crack in the wall of your home and not all of them are a cause for serious concern. Naturally after a new house is built it settles and some small surface cracks can appear in the plaster or dry lining. These types of cracks usually run vertically.
More cause for concern are cracks in the wall that run at a horizontal angle or those that run at a jagged 45-degree angle. This type of movement could indicate a more serious issue such as water ingress, corroded cavity wall ties or movement in the foundations.
It is always wise to contact a structural professional for advice if you are at all concerned.
The usual repair solution for this scenario is crack stitching – a process where reinforced steel rods are placed across the divide in the wall and chemically bonded to help tie the structure of the wall back together.
This process will ensure no further movement occurs, and the wall can be repaired back to the original finish.
Bulging or Collapsed Walls
A common cause of bulging or collapsed walls in modern homes is a failure of the cavity wall ties. As the name suggests cavity wall ties are used in-between the inner leaves of the internal and exterior wall of a building in order to tie the walls together. The ties play an important role in adding strength and providing stability to the wall, and preventing bulging or cracking.
