Timber Treatment

Dry Rot

Submit an Enquiry:

Dry Rot (Serpula lacrymans).

This is the fungus which is responsible for most of the destruction of timber in buildings. It lives on the cellulose of damp timber and requires damp, warm, stagnant conditions for its cultivation. Once established it will spread to timber that would appear to be adequately ventilated and reasonably dry. An attack which has begun will push out its strands or hyphae until drier wood is encountered.

They extract nourishment from timber reducing it to a brittle condition and finally causing it to crumble away. Strands are known to have the power of percolating through heavy brickwork and masonry following the line of damp in search of further timber to attack. The moisture is carried through the strands, which are hollow, and so another zone is rendered suitable for destruction.

When the fungus has reached a certain stage of maturity, the fruit bodies are produced. These are generally in the form of flat pancakes growing on the wood or on the brickwork and plaster near it. The fruit bodies have brick red centres which give off prodigious numbers of red rusty seeds or spores. The infestation is usually caused by faulty construction or faulty maintenance. When the source of moisture has been removed, the fungus will eventually cease spreading and will lie in a dormant state.

Our methods for timber treatment include drilling and injection with boron gel for large section timbers and low pressure spraying of roofing timbers, flooring timbers etc. We also offer treatment by fogging method to inaccessible areas such as sub-floors. Where problems of dry rot and wet rot are encountered our services include the treatment of masonry with fungicidal chemicals.

In situations where large section timbers have decayed but require to be retained, we offer a system of in-situ repair using resin based systems.

We are pleased to offer a service of visual strength grading of timbers in existing buildings and timbers for use in new buildings.

We also offer a timber resin splicing service using the Timber Resin Spilcing System (TRS) manufactured by Property Repair Systems of Devon.

TRS splicing is a system of repairing structural timbers in-situ (trusses, bressummers,tie beams, rafters, joists etc.) using timber to timber resin/bar connectors. TRS technology, backed by sound structural engineer calculated strength, enables us to repair in-situ structural timbers at the bearing end, mid span or in partial section providing the following major benefits:-

We specialise in:

The eradication& prevention of woodworm infestation
The eradication of wood-rotting fungi – both dry rot, Serpula lacrymans and wet rot, Coniophora cerebella
Timber resin splicing
Visual Strength Grading of Timbers

Minimum damage to parent timbers.
Butt jointed splices which do away with the need for further pockets in support walls.
Cosmetic appearance – can be made in matching timber, including hardwoods. No unsightly steel splices, plates etc.
Highly cost effective.
Manufacturer guaranteed for the life of the parent timber.
Using renewable materials.
