Timber (and walls) suffering from dry and wet rot, plus insect attack can be treated effectively using a compound of Boron. This is frequently referred to by its trade name of Borax. Also known as DOT (disodium octaborate tetrahydrate), this material is highly toxic to fungi and insects. DOT dissolves in water and can be inserted into the timber in solid rod form, or applied to the surface (or injected) when dissolved with Glycols to form a paste or gel. The DOT distributes itself within the timber according to the moisture content. The environment within which provides an opportunity for insects and fungi can live is called a biosphere, DOT acts as a biostat and deprives them of the ability to use that environment.
The images above shows a boron rod inserted into a timber frame. Rods can be used to relieve and cure rots and insect attack and also as a preventative measure against such attacks. Used, even with pre-treated timber, in new joists ends underground or in barn conversions with damp walls, you can be assured of preventing rot or insect attack.
Boron treatment products are part of a huge range of products available from Property Repair Systems. These products enable repairs and prevention treatment on;
External - window frames, door frames, posts, timber frames, wall plates, rafter ends, purlin ends, facias, soffits, telegraph poles, railway sleepers.
Internal - window frames, door frames, skirting boards, staircases, joists, carrier beams, bressumers (main beam in a timber construction), lintels, arches, rafters, tie beams, purlins, ridge beams, 'A' frames, trusses (King Post and Queen Post) and lath and plaster ceilings.
Types of damage:-splits, cracks, holes, end decay, mid span decay, excessive bending or deflection, decorative, fire, water, wet rot, dry rot and insect attack.
Even floor and ceiling voids can be treated for existing or potential fungus caused by condensation or water damage, by "blowing" a water carried powder form of boron into the cavities.
For all Furniture Beetle and even Death Watch Beetle attacks a dissolved Boron powder can be used to spray or paint on timber.
Dry rot cannot survive and travel at a moisture content of less than 18% in timber. Elimination of the moisture source has always been the prime objective. The practical reality, especially with structures has been that immediate drying out to below the danger level cannot always be achieved before reinstatement.
This is the basis on which preservative treatments are justified. However, many such treatments are unnecessarily destructive and expensive because they rely on old techniques where cut back is a security for the Treatment Company and the Client.

These Boron based treatments can be supplemented with a localised preservative paint coating, to provide a NO-GO ZONE, over which Dry rot cannot travel to reach other untreated areas.

A unique powder concentrate, ready to dissolve in water, designed to treat timber by brush, spray or MicroBlower. It avoids the hazard problems of many liquid preservatives by using only water as a carrier. It can also be used in most situations to replace most other insecticides, including Permethrin. Especially useful on areas of floor in, for example, bathrooms where water is expected to splash. The diluted powder, unlike many solvent based treatments, is completely odourless, as is the gell which is used in areas already showing a manifestation.
A unique SUPER STRENGTH paste using a special blend of technical grade glycols as the carrier. It can be injected into timber, or spread on the concealed surfaces, with the advantage of supplying a highly concentrated mobile preservative which will spread even at low moisture content levels. Simple to apply with a standard skeleton gun; more effective to use because of the higher available level of active content, which allows the use of smaller (8mm, rather than 10mm, rods) and/or fewer drill holes.
A specially green pigmented preservative biocidal emulsion paint designed to prevent the surface spread of Dry rot. Ideal for timber and masonry in the treatment and adjacent areas, to provide visual lasting evidence of treatment. It prevents surface spread of strands and mycelium.
These solid rods HIGH STRENGTH Boron 173 are used to protect timbers which are constantly or occasionally damp: external joinery, wall plates, embedded beam ends, posts etc. They can also be used in conjunction with BORON ULTRA 78 paste, to act as a long term reservoir (8mm x 24mm and 8mm x 65mm).
