LOW COST RISING DAMP TREATMENT
The photos shown relate to the inspection of an internal wall in Tooting, Wandsworth London SW17 The property comprised of 2 bedrooms and was built around 1880, The external ground level was only 5 cm below the internal finished floor level inside the property. Houses today usually have a clearing of at least 15cm from the damp proof course to the external ground level.
In this case we used the 3 coat Sika 1 renderi specifaction when applying multi coats of waterproof render to hold back the effects of water ingress via hydrostatic presure. This in an excelent and proven method used for over 60 years and found used in vaults, coal cellars, vine cellars etc.
Should the basement area been totaly submerged we may have used the Oldroyd X membrane. If the basement was below the water table and had on occasions filled with water we would have used a combination of Oldroyd Xv Clear, a pump and sump system as per clients specification and Aquadrain. Even so this is just one method of waterproofing your basement.
The installed damp proof course prevents moisture continuing to rise into the walls, however, due to the effects of the ground salts, the walls will not dry out effectively unless the existing wall plaster is removed and replaced using a salt retardant rendering system, such as Vandex's premix waterproof rendering system. Where high ground levels exist, our structural waterproofing or tanking system may also be required in conjunction with the chemical damp proofing. We offer a comprehensive service to home owners and property professionals or can work with your builder to undertake the specialist damp proofing as part of their programme of works. Treatment is undertaken by our own skilled workmen. Typically, treatment involves removal of the skirting boards and wall plaster on the walls to be treated.
The wall plaster is removed to a height of approximately one metre, however depending on the salts within the masonry and several other factors, the height of the necessary replastering may be increased and will be individually specified once our surveyor has carried out an inspection of your property. Replastering above one metre high is not uncommon. The damp proof course is installed into the walls by pattern drilling the masonry at the base of the wall and injecting a specially formulated solution of siliconate injection fluid, until the entire depth of the wall is fully impregnated.
The walls are then replastered using a premix waterproof rendering system, which is purpose designed to provide a salt retardant, waterproof render to combat the effects of the ground salts in the masonry and provide a dry internal finish. Following the application of the waterproof rendering system, we will apply top coat skim plaster to provide a smooth finish. Our installations are carried out to the highest standards and are covered by the most comprehensive guarantees available
ATRUSS PRESERVATION remedial damp proof course treatment involves installing a chemical damp proof course using injection fluid or dpc cream, which is installed by pattern drilling the appropiate mortar course at the base of the wall and injecting the waterproofers under pressure into the masonry substrate. Our chemical injection process, is low odour and cures within the masonry wall to form an impervious barrier to rising dampness, which prevents moisture rising from the ground into the treated walls. Adjacent abutting walls are isolated using a vertical damp proof course. Used in conjunction with our specialist waterproof rendering system, the damp proof course system, provides a reliable, highly effective and cost effective method for the treatment of rising dampness. Specialist replastering of the walls following the damp proof course installation is essential.
Basements are fast becoming as popular as an extension. In parts of London, stamp duty can be as much as £30K, add that to moving costs and the price of a larger home, many of our clients agree it makes better financial sense to convert an existing or create a new basement than move home.
Throughout South West London SW19, Fulham SW6, Clapham SW4, Wandsworth SW18 we have been adding further living space to properties without the need to extend any further. We are the south london basement company to deal with! The great advantage with basements is that they not only add a whole new floor, it's also space that can be used in many different ways. With a loft extension, the space is so far from the living areas that it can only really be used for bedrooms, studies or bathrooms. Basements are close enough to the ground floor area to be used as playrooms, nanny bedrooms and bathrooms when a new baby arrives, living rooms, kitchens or accommodation for relatives.
With the demands of modern lifestyles, basements are increasingly being turned into leisure areas with home cinemas, pool and table tennis tables, home gyms or even swimming pools. You can also create an independent entrance or exit out into the back garden from the basement. A basement creates a lot of extra space, which can be used for absolutely anything – it also frees up the rest of the house to use in different ways. For example, many people put a utility room, shower and toilet in their basement, irrespective of what else they have planned for the space.
Whether you are converting an existing damp dark basement into extra living space or the waterproofing in your basement is failing, Our installations are carried out to the highest standards and are covered by the most comprehensive guarantees available.
