Timber Resin Repairs & Property Preservation

22nd November 2017

Categories  Timber Treatment

In this blog, we explain what a timber resin repair involves and their importance as a timber treatment method for property preservation.

 

Timber decay in properties and the expense and difficulty to replace decayed timbers can in part be blamed for the deterioration of many historical properties. A construction technique that provides a solution to this problem and one that’s gained a lot of popularity in recent years is the method of timber resin repairs.

What are timber resin repairs?

Timber resin repairs are a construction technique used to upgrade and repair old and worn structural timbers that have been damaged and weakened by problems such as wet rot due to moisture ingress, woodworm, structural movement or where old timbers have simply weakened over time.

What makes this method of timber treatment so useful is that removes only the decayed section of the timber and so avoids the need to completely remove and replace the full structural timber.  This makes it a cost effective and time efficient solution, particularly ideal for the preservation of historical buildings.

What is involved?

The general process involves the removal of the decayed or damaged section of timber and a new section built or inserted. Lengthwise slots are drilled into both the new and existing timber and reinforcing bars are then placed into these slots so connecting the repair to the healthy timber section. Resin is poured or injected into the repair which surrounds the reinforcement bars. This then hardens so the sections of timber are bonded together.

Types of timber resin repairs

Different methods are available depending on the type of decay and structural requirements. Examples are Timber Resin Splice, whereby a whole new a timber section is manufactured to replace the decayed section; the Flitch Beam System where a steel plate is sandwiched between two wood beams held together using bolts; and Timber Beam End Repair which provides a method of repair when a timber is rotten due to being in contact with wet brickwork.  A specialist timber treatment company will know the type of repair to use.

Timber resin repairs are a long-term and cost-effective timber treatment technique

Timber resin repairs offer big benefits as a form of timber treatment. It is a long-lasting solution using steel bars and resins that form a strong bond with the timber. They are extraordinarily hard wearing and resistant to damp, and fungal infestations.

Resin repairs also provides a property preservation method that will preserve as much of the original wood as possible and, where repairs need to be sympathetic to retain the look of the original features. Resins are becoming available in an ever-increasing number of finishes and characteristics which can be shaped or moulded into the timber profile which can be sanded down, grained and stained to create a finish that is close to the appearance of the surrounding parent timber as possible.  This is an important factor in the preservation of historical and period properties.
