We are highly experienced damp proofing and timber preservation specialists. Damp can manifest itself in a number of ways, upon inspection we will diagnose correctly whether damp is present, the type, the cause and of best course of remediation.
Rising Damp
Rising damp rises up from the ground and can be found in buildings where there is either no damp course present, or the damp course has become ineffective for any number of reasons. The damp course may have simply deteriorated, or it may have been bridged by the external ground level being built up, for example sandstone eroding over time and debris collecting in the wall cavity.
Rising damp can be seen as tide marks appearing on a wall normally to a height of 1m. The tide mark or stain is generally caused by the chloride and nitrate deposits, known as hygroscopic salts, which are left in the wall and plaster when the dampness in the wall evaporates. The hygroscopic salts have the ability to attract ambient moisture and will therefore remain damp until removed injected and re plastered,
Penetrating Damp
Penetrating damp is caused usually as a result of poor property maintenance for example defective and blocked guttering, defective plumbing causing overflows as well as environmental factors such as wind driven rain. Such damp can penetrate the structure of the building and can be the cause of internal adjacent timbers becoming damp and as a result degrading through dry rot and wet rot infestations.
Condensation Damp
Condensation is caused where there is a lack of airflow and ventilation in a property. Walls can become damp causing damage to the plaster and black mould and a musty smell is likely to be present.
Leaving damp problems untreated
Left untreated, dampness can and will spread throughout a property, becoming progressively worse in the form of timber decay, damage to brickwork and plaster and increasing the risk of dry rot and insect infestations.
We are specialists in our field and will always give accurate, impartial advice and will only ever specify a particular course of action if they believe it is necessary to rectify you individual situation.
Tanking
Converting a damp cellar or basement can be a surprisingly inexpensive way of increasing living space and can substantially increase the value of a property
Waterproofed cellars and basements can be converted into kitchens, bathrooms, wine cellars, living rooms, studies, or even recording studios. You are limited only by your imagination.
The Cavity Membrane System is, as the name suggests, is a polyethylene high gage studded sheet which is fixed to the walls, floor or ceiling with specially designed plugs with fitted seals.
It creates a cavity between damp masonry and a new wall surface. The base of the wall carries a drain channel which normally runs to a sump pump or manhole, thus relieving water pressure.
The system can be either dry lined or plastered directly on to to achieve a smooth plastered finish. This method of tanking:
- eliminates the risk of condensation associated with cement render tanking.
- is not affected by structural movement or vibration from traffic.
- manages the water pressure by allowing the water to drain away, eliminating the risk of pushing the water elsewhere.
