Introduction to the Timber-Resin Splice (TRS)

What is it? It is a simple way to attach a new piece of timber to an old one, whether to an end or mid span.
Why bother? Because 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: for example, a TRS may allow the low disturbance (and therefore cheaper) repair of shop front beams, roof purlins, tie beams and beams shared between properties.

Standard Range of fitting types - A to H

A new, Boron pre-treated softwood piece, with the 'shear connectors' factory fitted, is attached to the end of the damaged piece via slots, which are filled with the Structural Epoxy Pouring Resin. This is a fast and economical repair suited to accessible timbers, particularly joists and tie beams.
