We are dedicated to providing our best damp proofing to this specialist industry and our customers throughout Carlisle, Cumbria and Southern Scotland. Anything less than perfection just won't do, especially when it comes to professional damp proofing.
We are experienced with all kinds of specialist damp proof treatments, from flood damage to domestic home and commercial businesses, our professional damp proofing services range from DPC injection and SovDrain cavity membrane system which is ideal for both above and below ground situations. K11 tanking systems are highly successful in waterproofing above and below ground.
We offer our expert damp proofing services in Carlisle, Cumbria and the surrounding areas whatever the size of the work required.
We are proud of our comprehensive expert service. A thorough and professional damp proof survey will be carried out before every job and an exact specification will be made for every individual job and situation. Davidson's DPR get it right first time.
Rising damp is best described as slow and upward movement of water, generally in the lower sections of walls and floor-based structures. The movement occurs by capillary action (when liquid flows in narrow spaces and gaps without the assistance of gravity, hence why it can rise). Rising damp is usually lower than 1.5 metres, however it can on rare occasions reach 5 metres in height depending on the cause and exact situation within your property.
The water travels upwards through porous materials such as brick, plaster and mortar. It is usually identified by a visible 'tide mark' on the lower section of affected walls and areas. This tide mark is caused by soluble salts contained and carried by the water as it travels - due to the process of evaporation, these salts build up at the peak height of the rising damp.
The main causes of rising damp are:
A number of expert methods are available to treat and prevent rising damp, with the most common being a new damp proof course using low pressure injection of a specialist treatment into the affected walls. Once this process is complete, we will professionally re-plaster the walls which is an essential part of the process.
Where appropriate, we can also opt for K11 tanking which is brush applied to the walls when the low pressure DPC injection treatment is not suitable. We can also offer SovDrain cavity membrane.
Penetrating damp is one of the most common damp problems in homes and buildings. It can occur for many reasons, through walls, roofing or openings such as windows and doors. It can result in visible damp and wet patches on walls and black mould on walls and ceilings. Plaster and paint may blister and overall there may be a musty smell to the affected room(s).
Water penetrates through the outside of a property to appear inside, and common defects that cause penetrating damp include:
Whilst penetrating damp is more common in areas with single-skin walls, it can also occur in cavity walls if water finds a way to track across wall ties or is rubble builds up inside the wall cavity.
The most common treatment for penetrating damp is to first address all of the reasons for the damp getting in to your property in the first place. From there we offer the K11 tanking system where the affected areas are treated with appropriate chemicals to form a water proof barrier to prevent any future penetrating damp problems returning. SovDrain cavity membrane is also a great way to stop penetrating damp every system has its place and is more suitable for certain situations which is why we offer them all.
Condensation is perhaps the most common cause of damp problems within homes and offices. It comes from water vapour within the building and common sources of this water include cooking, bathing, showering and dishwashers. Many modern homes are inadequately ventilated so humidity builds up within the property and then condenses in areas of poor air circulation when the internal house temperature naturally changes throughout the day.
As with penetrating damp, excessive condensation can result in black mould and mildew which is unsightly and can have a negative impact on your health especially for those who suffer from asthma and/or allergies.
There are three main treatments we can provide to remove and prevent the re-occurrence of condensation related damp problems in your property:
