We have over 25 years experience in dealing with Insurers, their Loss Adjusters and other experts. Mainly these claims are for structural movement arising from the operation of an insured peril.
Most house insurance policies cover damage due to an escape of water, and again most will cover subsidence. An escape of water, e.g. from drains, is very often a cause of structural movement and cracking in the walls of buildings. Dangers to your property for which you are insured are known as Insured Perils, and once an Insured Peril has operated you can invoke the coverage of your policy. Below are the usual steps taken when initiating and resolving an Insurance Claim for structural damage due to an escape of water.
Structural movement generally occurs in a structure when the ground bearing the structure yields, under the load of the structure, and compresses to such an extent that the structure settles at the point of failure.
This settlement at the foundation line gives rise to tensile stresses in the masonry of the structure, which generally cause diagonal cracking in the walls of the building. These diagonal cracks generally occur at weak points such as window and door opes. The simple diagram at the top of the page shows a typical crack pattern that may occur as a result of subsidence.
Very often the cause of the ground yielding is erosion of the soil due to movement of water, often due to defective sewers or water mains leaking water. This erosion decreases the bearing capacity of the soil, with the result that the house sinks slightly into the weakened subsoil. This type of erosion is particularly common in the greater Cork area due mainly to the make up of the soil and the Limestone bedrock in the area. The water which has escaped from the drains will not only erode the soil by washing away fines, but will also erode the Limestone bedrock. To arrest this structural movement it is generally necessary to underpin the house. The type of underpinning required will depend on the type of soil present and the existing foundations, and should only be specified by a suitably qualified engineer.
A simple hydrostatic test carried out on the sewers will determine if they are leaking. Digging a trial hole exposing the soil at the foundation line will facilitate an assesment of the soil to determine whether it has softened or not. If it is established that there is an escape of water and that the subsoil has softened, then it is likely that the cost to repair the damage caused by the escape of water will be covered under the relevant house insurance policy.
