Rising Damp, common in older buildings, is probably the most asked for service we provide. Caused by moisture rising though capillary action in stone/brickwork, it can create problem dry rot/wet rot and salt contamination. In most cases it can be dealt with the injection of a chemical damp proof course and the removal and renewal of the plaster.
This system is similar to our Basement waterprofofing system. APS fix directly to the wall using proprietary fixings, the membrane damp proofing systems have many advantages over conventional systems. back
- no need to wait 6 months to carry out decoration
- deals with penetrating damp caused by high ground levels
- it indulates the wall, reducing the effects of condensation and heat loss.
Basement Waterproofing
As house prices continue to rise an alternative to moving house is to extend into areas underground the property. Making these areas habitable can be achieved by Basement Waterproofing. Cavity Drainage systems are different from previously ineffective systems. Rather than hold back the water they accept it is getting in but simply manage it. With the use of membrane and pumps the water is channelled away, ensuring a dry wall.
As you can see from the pictures these systems can be used to create rooms in otherwise forgotten spaces. The leading manufacturer of these types of systems is John Newton and Co who produce 'Newton 500' and 'Newton Newlath' - the most commonly used products for basement reclamation.
Condensation
Is caused by a lack of heating, ventilation and insulation. It is the most commonly misinterpreted as rising damp - an expensive mistake. Condensation causes mould on carpets, clothing and wall coverings, heat loss through damp walls and serious health concerns. Mechanical systems can be fitted to reduce condensation. Fitted into a roof void these mechanical systems extract moisture and create a positive air pressure drying out surfaces from moisture ingress.
Many factors can cause decay to timbers in buildings. The two most common from which all rot stems is water and timber attack. To remove it remove the moisture source and replace the timber. A leaking downpipe, gaps in windows, masonry all contribute to water penetration and timber damage.
Insect infestation is at the root of woodworm. The most common beetle is the 'Anobium Punctatum'.
It lives in three year cycles. The first six to eight weeks it is an egg emerging as lavae which go on to feed on the timber for the next three years. Eventually the' lavae purpates' and changes to an adult beetle which then eats its way through the surface to fly off and find a mate, before the process begins again.
Woodworm is treated by spraying with a water based insecticide. This coats the surface of the timbers and produces a layer of residual fluid which will remain in place to ensure that any woodworm eating their way out of the timber will become sterile and unable to breed.
Epoxy Resin
Epoxy resin repairs problems in situ and can be adapted to take on even the largest section timbers in the most confined spaces. These types of repairs are sometimes the only solution to repairing timbers such as Church roofs trusses and bressummer beams, where it is not possible to remove it without great expense.
