Definition Of Water Ingress

Water ingress is simply the process of water entering penetrating its way into the property.

There are a number of potential problems that can occur as a result of water entering the building. There is immediate damage from water entering the building in the form of damp but there are further problems that can occur in the future.

Future problems are fungal decay, damage to walls and potential health problems from mould. It is always best to deal with the issue of dampness as quickly as possible by contacting a local damp proofing specialist.

What Causes of Water Ingress?

The root cause of water ingress is ordinarily a building defect or fault. Therefore, regular property maintenance should be carried out to identify potential problem areas. The types of problems to look out for at a property include:

  • Roof damage- having broken tiles, problems with chimney such as faulty flashing around the chimney. This will need a professional to provide an inspection of the roof for any damage that is occurring.
  • Faulty or blocked gutters- if the gutters are blocked or faulty then the water will start to penetrate its way through the property.
  • Walls- blocked air bricks, damaged pipework, a missing damp proof course (DPC), faulty internal plumbing, rendering and mortar becoming porous.
  • Windows- faulty flashing around the window frames.
  • Rising damp- if there is a failure damp proof course or a missing DPC can be one of the causing of water ingress.
  • Plumbing issues- if there are leaks in the house can also cause water ingress.

Water Ingress in a Cellar or Basement

Having water ingress problems in cellars and basements is a big concern for property owners across the UK. Ordinarily, steps are taken at the design stage of a building to incorporate waterproofing of some form or another. Sometimes though, especially with older properties, this may not have been done. As a result, other forms of retrospective waterproofing may be required.

Type C waterproofing systems are a popular waterproofing system that is used to safely drain any water out of the property to a convenient drain off point. The key components of a Type C waterproofing system include cavity drain membrane, perimeter drainage channels and sump pumps. Another method that might be used is the use of tanking the cellar which involves using a waterproof slurry coating on the walls.

If you don’t have the necessary waterproofing system in place or has become damaged over time, then the property might experience water ingress problems at some point. We would always recommend contacting a waterproofing specialist who can deal with a damp basement.
