Timberwise use completely unique technique to remove damp in Brighton


Products Used: DriWise

In an area popular with families, and with Preston Park station situated less than a mile away, lies a two storey bay fronted terrace house located within this sought after location in Brighton. The client called upon Timberwise South East as they were concerned about dampness in the property.

Did you know?

 There are 24  Grade I and 70 Grade II Listed Buildings in Brighton and Hove. The oldest listed building is St Wulran’s Church, this flint-built church dates back to the 12th Century. The tower, with “Sussex Cap” spire, was added in the 13th century, and a porch was added during a 19th-century restoration. 

Following an external inspection of the property, it was revealed that the internal elevation within the second reception room was abutting an area of the high ground level. The external defects of the property included defective rainwater goods overflowing to the rear, and porous pointing.

Internally to the ground floor, the walls revealed severe decorative spoiling and de-bonding of the existing wall plaster. Timberwise South East, inspected the internal damp walls using an electronic moisture meter, where high readings were recorded.

After consideration of the instrumental readings, it was determined that the walls were of insufficient integrity to withhold the ingress of laterally penetrating moisture. The tenant also made Timberwise aware of a secondary problem with damp to one elevation of an external facing wall to the bathroom. Moisture readings taken at the time of the survey, together with the visual internal damage to wall plaster, indicated the presence of laterally penetrating damp.


Due to the nature of the works, Timberwise had a duty to draw the customer’s attention to the fact that the Party Wall Act 1996 applied. This Act requires the owner to notify their neighbours of any proposed works and obtain consent before the work could commence.

With permission granted, Timberwise could now commence the action. For the ground floor, the Timberwise’s recommended solution was to install by diffusion, a new damp proof course using the DriWise system. Completely unique to Timberwise, DriWise has been specially formulated to combat the effects of rising damp, with superior performance. The purpose of a injected damp proof course is to control the upward capillary movement of water from the ground into the wall.

The Timberwise Technicians prepared the area, taping down dust sheets within the work area, also protective polythene sheeting was placed over large pieces of furniture in the designated work area. The existing wall plaster was removed, in order to prevent possible future problems with hygroscopic salts spoiling the plasterwork and decoration. This was replaced with a dry Driwise internal finishing system.

The Timberwise Technicians installed the DriWise damp proofing system to the walls by means of a special applicator gun, and once installed it starts to migrate immediately in forming an effective damp proof course.

As part of the process, Timberwise also installed a wall/floor cementitious joint to further protect the property. Upstairs, due to the severe nature of the laterally penetrating dampness, Timberwise adopted a different approach. Once the original salt/damp affected plaster was removed, a 3mm impermeable mesh membrane was installed. This would then ensure that no further damp within the wall during the drying out process could penetrate within the property.

Once the work was complete, Timberwise advised redecoration in the form of water-based matt emulsion paint can only be applied after six weeks, providing the plaster surface is dry to the touch. On no account must vinyl silk paints or vinyl wallpaper or any other impermeable covering such as artex type finish be applied. After 12 months, it is permissible to apply wallpaper or ceramic tiles. During the drying out period, it is recommended that an adequate air flow is maintained to the newly plastered areas and that no permanent construction, which would impede such air flow, is undertaken


With minimal preparation and application time, Driwise minimised any possible disruption to the homeowners, meaning they were able to go about their day as normal. Although the customer knew Timberwise is a founder member of the Property Care Association and fully accredited for health and Safety by SAFE contractor, CHAS and Constructionline, they also had peace of mind that all specialist work undertaken by Timberwise was covered by long-term guarantees. Driwise is a GPI and BBA approved product and comes with a 20-year guarantee as a dry solution to rising damp. This gives the customer complete the peace of mind that should the solution provided by Timberwise fail, their property is covered.

Timberwise also advised a damp proof course does not prevent or reduce condensation, water penetration, leakage or damp where masonry is constructed below ground. Proper maintenance should be undertaken to ensure that roofs and flashings are watertight, rainwater goods are efficient, external window cills have drip trays, pointing and external render are sound, and that drainage arrangements are adequate to dispose of rainwater and excess ground water from the property.

 It may come as no real surprise that dampness in homes, is one of the most frequent problems homeowners can face, Thanks to our technical knowledge coupled with our dedication to providing high levels of customer service, our customer was left with a damp-free home.
