Damp Proofing Treatment in Kent


Products: Masonry Protection Cream, Cavity Drain Membrane

Settled within the rolling countryside lies Grade II Listed family house with accompanying outhouse made of brick construction with part tile hung upper elevations under a tiled roof. The owners of the property wished to transform what was an old unused barn into a home office. What concerned the owners, however, was the erosion of the exterior walls which they believed to be the result of rising and penetrating damp.

During Timberwise’s damp specialists in Kent external inspection of the property, it became apparent that there was no evidence of an original damp proof course. This was thought to be due to the age of the property and the high ground levels.

The inspection of the internal wall surfaces of the property was completed using an electronic moisture meter, where high readings were observed at full height. After consideration of the instrumental readings, soluble salt contamination, and other relevant factors, it was assessed that the elevations within the building were affected by dampness and the installation of a chemical damp proof course would need to be put into place.

Lateral moisture penetration due to porous masonry was noted to the building generally, the moisture ingress was not in the form of free-flowing water. We, therefore, recommended a vertical physical barrier to be installed in the form of a cavity drainage membrane to the damp wall surface at full height.

Water Absorption Test

During our inspection of the property, our surveyor carried out a water absorption test to the front elevation and left-hand flank wall of the property. This test indicated that the external walls of the property were particularly absorbent and would benefit from an application of WeatherTek Masonry Protection Cream. When masonry becomes wet, its temperature drops and it becomes colder, and cold walls can mean colder buildings as energy/heat escapes much more readily. WeatherTek works by providing treatment for rising damp, increasing the thermal efficiency of your masonry by up to 29%, whilst allowing the masonry to breathe. The application is designed to be applied to stable masonry with no outer decorative coating.


Masonry Protection Cream

A period of up to two weeks was required to allow the newly pointed areas and rendered areas to cure before applying WeatherTek Masonry Protection Cream. Following this, our technicians applied one coat of masonry protection cream to the external walls indicated,  protecting the door and window areas as work proceeded. Also, of great benefit to the property owner, masonry protection cream carries a Timberwise 10-year guarantee, alleviating any concern should damp issues persist.

Type C Waterproofing System

As the property was intended for domestic living accommodation, the waterproofing specification had to reflect its intended purpose. In order for the conversion to be made fully dry and habitable, Timberwise installed a cavity drain membrane lining system to the walls and floor.

The membrane terminated below the surface of the solid floor into a purpose-built drainage channel. The system was then fixed to the wall surface with sealed brick plugs. These plugs then became the fixing points for the battens to support a dry lining system. Additionally, the outlet for the drainage channel was connected to the external drainage already in place. The installed system now provides a dry internal surface, without the need for extensive damp proof hard renders.

Damp Proofing System

Following the findings, Timberwise technicians also installed a  damp proofing system onto the damp walls, which was supplemented by vertical installations as necessary to prevent filtration and to provide continuity of the system to the split-level structure.

Another beautiful day at another beautiful property. Through a combined method using the application of WeatherTek, and Cavity Drain Membrane, this property is transformed  into a habitable living space”
