Dry rot in a detached mansion apartment block
The timber specialists at Timberwise Kent were called to a detached mansion apartment block in Folkestone, to investigate problems with damp and a suspected dry rot outbreak, following a leak from a rainwater downpipe.
The apartment block also showed signs of a previous dry rot outbreak, especially within the floor timbers. The decayed timber flooring was beyond repair as it was also infested with wood boring weevil, death watch beetle and common furniture beetle.

Dry rot, in certain circumstances, can cause serious damage due to its rapid growth. Spores will germinate and grow in timber with moisture content anywhere between 20% and 30%. Our Surveyor, Robert Matthews, recommended that treatment was carried out as soon as possible.
The ground floor timber had decayed beyond repair, our trained technicians removed the infected wood in order to gain access to the area under attack. Technicians then carried out drilling, irrigation and sterilisation of the exposed masonry complemented with a surface application of a chemical treatment.
The permanent chemical deposit on the treated timbers will prevent any possibility of an attack reoccurring and will enable the structure to dry out and prevent remaining dry rot spores from germinating.
Within the basement, as the block timber flooring had been infested with wood weevil and infected with wet rot, Timberwise recommended removing the timber floor altogether and installing a cavity drain system with a mixture of sand and cement spread over the floor on top the membrane.
To combat the rising damp, Timberwise technicians used DriWisetm a unique to Timberwise water-repellent cream product. This water based product is injected directly into the walls into the first horizontal mortar joint above the internal ground floor level.
This simple and efficient installation of a damp proof course requires minimal preparation and application time minimising disruption and ensuring peace of mind.
