Timber Resin Repairs
MacLennan use a timber resin 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.
A common installation is to upgrade the beams that have to be retained but need 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 timber resin installations 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 either no alternative,or the alternative would be more costly and destructive. Another common 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. Again, 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".
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 timbers or carrying out traditional splices requires considerable opening up and Clients may not wish to disturb the ceiling, floor or partition. 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.

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.
