What is in your damp proof course?

A damp proof course is vital to the continued ‘health’ of your home. Aside from what it does, it is important to know what it is made of and how it is constructed– both for your peace of mind and in the event of any work which will need to be carried out in the future.

Methods and materials have changed over the years when installing a damp proof course, but the underlying idea has remained the same throughout. The basic method is to ensure that the building above ground is separated from the underlying foundations.

This is done through various materials, including flexible materials such as rubber, bitumen and plastic sheeting, semi rigid materials and rigid materials with low absorption rates. In addition to the layer being close to the ground, it must also be continuous. If this is not the case, then it can render the damp proof course ineffective.

Houses have historically been made from permeable materials such as stone and finished with breathable finishes. In the past there were some instances where the materials were not up to the task though, with one notable exception being the use of asbestos.

Some older buildings may have damp proof courses which contain asbestos, which is very damaging to your health and should not be worked on without proper training and preparation. It nearly all cases it is a legal requirement to inform local authorities of asbestos when it is found and use the services of professionals to remove such material.

It is important to use the best practices and most up to date methods when installing a damp proof course. Be sure to get the best results with our range of damp proof solutions, which all offer fantastic results.
