Example

 

Bindon House Hotel - the roof tie beams were badly affected by Death Watch Beetle, Wet Rot and Dry Rot. These were replaced with TYPE E Timber-Resin Splice Units and timbers like these should be treated with Boron Ultra 12 by spray, Boron Ultra Gel to end grain and vulnerable surfaces and Boron Ultra Paste by injection.

Dry Rot on Office Wall

Example

 

Manor House, Warwick - extensive infestation had resulted in massive areas of Dry Rot mycelium (skin) and sporophores (fruiting bodies - mushrooms) on timber and masonry. Previous treatments with conventional chemicals had failed to stop the spread of fungi. Boron Ultra 12 powder in water was applied by spray to timber, masonry and sub-sites, Boron Ultra Gel to end grain and vulnerable surfaces, Boron Ultra Paste and Boron Ultra Rods to 8-10mm holes drilled to prescribed hole pattern, to surrounding areas at least 300mm in all directions from the limits of the attack and to all timbers at or above 18% moisture content.

How to prevent Woodworm and Dry Rot

 

1. Prevent the ingress of moisture by eliminating penetrating and rising dampness

2. Treat vulnerable timbers (those above 18% moisture content) and those subject to seasonal dampness (e.g. window and door frames, wall plates) with Boron Ultra Rods, Boron Paste and Boron Gel. To prevent surface spread apply Dry Rot Paint, an emulsion that can be applied to timber and masonry. BRE testing proves that Dry Rot will not 'walk across' surfaces coated with this paint.

3. To avoid leaving timbers that are drying out vulnerable to Dry Rot, cut back wet rot damage and dry out/treat as above

 

Log House with Wet Rot

The Log House - before restoration

Example

 

The Log House, near Lymington - wet rot decay had destroyed a large number of logs on the weather side of this £1.5 million + home, facing Southampton Water. This left the damp timbers vulnerable to Dry Rot, so Boron Ultra Paste and Boron Rods were installed in the remaining sound logs to provide long term protection.
