If you need any help with any type of Structural timber repair, timber splits, shakes or cracks  Property Repair Systems staff will be pleased to give you completely free, no obligation advice on 01626 331351. The information you need may be in the project below. If not, call them for expert, impartial advice.

Repair of structural timbers has always been an expensive and time consuming operation. From a timber lintel in a Georgian terrace, to a huge tie beam in a barn conversion, if a new piece could not be spliced, or bolted on, the lot had to come out. Very often, even if it were possible to bolt a new section of timber on, the overlap for the bolts was so long it was almost like replacing the entire timber anyway.

Property Repair Systems, which employs experts in all types of timber repairs and treatments, are happy to provide a free telephone help line for your queries regarding timber treatment and repair.

We are very pleased to introduce the wonderful new technology, the Timber-Resin Splice System.

[-Timber-Repairs - TRS-]

Removing complete timbers or carrying out traditional splices in joists, rafters and other structural timbers requires considerable opening up of ceilings, floors and roofs, and most people would rather not take their houses apart.  In most cases complete replacement of a timber will be impossible by traditional means without scaffolding or roof removal, but a TRS will allow the Low Disturbance (and therefore cheaper) repair of beams, roof purlins, tie beams, lintels, joists and rafters. This method can even be used for repairing flag poles!

Click Repairs to Joists and Rafters, for repairs without removing sections of the ceiling.

Click Dry Rot for treatment of fungal decay and repairs.

Click Repairing Splits and Shakes for timber filling and injection.   

Click Roof Truss Repairs for structural repairs of roof frames. 

Using the Timber-Resin Splice System a section of timber can be cut out, in situ, and a new section added. The repair will be stronger than the original. 

Timber Repair

How is this done? Obviously for the benefit of this project we have simplified the procedure...But not by much! It really is an uncomplicated breakthrough allowing new, treated timbers to be installed with the minimum of fuss and disturbance. Timbers are not all accessible from the same place. While you may be able to get to a floor joist from the top by lifting a section of the floor, it is far easier to access a rafter from underneath. Property Repair Systems has devised different ways of repairing structural timber, to allow access from all angles. We have shown the most basic here, repairing a floor joist, accessible from first floor level. The first three images show  before, during and after scenarios in a first floor bedroom with a lathe and plaster ceiling below, The images after that show the method. For further instruction and all information, click on any of the images.

REPAIRING CRACKS, SPLITS AND SHAKES IN TIMBER.

Cracks in timber beams need not affect the overall integrity of the structure. Indeed, cracks in timber beams can be taken as a positive visual feature of the timber, which, in conjunction with the timber grain, distinguish timber from the more uniform man-made materials such as steel and concrete. The integrity of the timber can be called into question when it is impaired by cracks, splits and shakes and often it has required the replacement of a beam or rafter which has formed part of the original structure. This can now be overcome in a great many cases with the use of an injected epoxy resin. We recommend seeking the advice of a structural engineer for structural repairs.

Cracks, shakes, warps and fissures are formed as a result of the timber giving up moisture and shrinking. This may occur as part of initial drying or subsequent changes, during service, in the Equilibrium Moisture Content. The EMC of timbers inside buildings can range from 9% to 14%. Fibre saturation is reached in constructional softwoods at about 28%.

For cracks and splits that are greater than 5mm wide the void can be filled with an Mouldable Epoxy Mortar, but if the crack penetrates more than 30% through the timber it will be necessary to provide dowels (Epoxy-Glass Bars) across the filled section in order to 'stitch' the two halves together. The advice of a Structural Engineer should be taken with regards to the number, diameter, length and spacing of the dowels. The dowels can be made of glass fibre, carbon fibre, steel or stainless steel. We recommend the use of epoxy/glass or epoxy coated steel, set in a Thixotropic Epoxy Injection Resin.  

Click on any of the images below for advice on how to repair splits and a free, experts help line.

Split timber 

Clean out cracks or splits with a saw blade and vacuum out all sawdust. Fill the cracks with Mouldable Epoxy Mortar.

When the Mortar has set drill small holes, about 6mm in diameter through the epoxy into the back of the crack. Blow, or vacuum out the dust. Directly inject Thixotropic Epoxy Injection resin from the cartridge into the hole, until the resin flows from the adjacent hole. Continue until all the holes have been injected and cap off each with Mouldable Epoxy Mortar.

Timber repaired and finished

Sand off any excess Mortar and colour finish to suit the timber. If stitching is required the cracked areas can now be cross drilled and epoxy-glass or steel rods fitted in Thixotropic Epoxy Injection resin.

Property Repair Systems expert staff can help you with all kinds of timber repairs and are more than happy to give further information and advice.
