Timber Resin Repairs
MacLennan use a timber resin repair system for structural repairs on commercial, domestic and historic buildings across the UK.
Our timber resin repair system can be applied to strengthen timber beams, replace timber ends that have decayed, and join any timbers where traditional joinery or steel work is not possible.
We find that a common installation is to upgrade the beams that need to be retained but have to support a greater load than they are able to.
MacLennan offer a full design and installation service, though calculations can be provided for your engineer where required.
All work is carried out by fully qualified carpenters with experience in all aspects of timber repairs. MacLennan guarantees for timber resin repair installations last for a period of 10 years.
Timber Resin comes in many forms but TRS (Timber Resin Splices) is the most commonly used, mainly due to the fact that they are available in several forms depending on the accessibility of the repair i.e. side slot, top slot, etc. The repairs are relatively non-destructive and in most situations there is no reasonable timber resin repair alternative. In the situations whereby there is an alternative, it is actually more destructive and costly. Another common timber resin repair method used by MacLennan is the bower beam. These metal repair plates come in several sizes to suit the timber being repaired and the amount of timber that has been affected by decay. Just like TRS, they are less destructive and more cost effective than the alternate in most situations.
This video shows a step by step method we use for repairing timber beams by splicing them using the same species of timber with reinforcement bars or GRP rods pre-attached, referred to as "shear connectors".
Method
We first remove the unhealthy section of timber before routing the chambers for resin splicing in the existing healthy timber. We then attach the new piece of timber with shear connectors installed, cover them, and fill the chambers with resin, creating a join that is stronger than the original beam.
Why do we do this?
In many cases, removing complete pieces of timber or carrying out traditional splices requires considerable opening up of the building structure. Clients may not wish to disturb the ceiling, floor or partition within their building. In some cases replacement may be impossible by traditional means without scaffolding or roof removal. A Timber resin repair is often much more economical with a lower impact on projects that require a quick turnaround with minimal disruption.

Timber Resin Repairs for Historic Buildings
MacLennan carry out all forms of timber repairs. In many situations, the timber resin system is the only method that can save decayed timbers or upgrade structural timbers.
Timber resin repairs can be used when repairing historic buildings in order to limit the amount of original timber that can be lost when joining timber beams. It's sometimes the only way to retain the original timbers and to avoid further repairs to historic finishes.
We've worked with an array of clients across the UK, saving them huge amounts of time and money, as well as saving and maintaining important elements of traditional historic buildings.
