Structural Timber Resin Repairs
Timber resin repairs are a cost effective way to repair timber damaged by issues such as woodworm, wet rot and dry rot. They allow for expensive or difficult to source large section timbers to be left in place, while the decayed end is replaced. This may also remove the requirement to disturb historic ceilings and other features. These problems are common when timber is embedded in masonry walls that suffer with damp problems, often caused by building defects.
Rentokil Property Care are able to assess the extent of damage to timber, and provide recommendations to prevent the damp problem, and specifications for timber resin repairs. This allows for sections of the original timbers to be retained, rather than a complete replacement installed.
Specialist timber resin splices (TRS) are used to replace the damaged section of timber, fixing the problem long term.
Rentokil Property Care have a number of CSRT and CSTDB qualified surveyors, are Property Care Association Members and have a number of branches across the United Kingdom, meaning we have qualified and experienced surveyors and technicians local to you.
Timber Resin Repairs
Timber treatments are often required in buildings with structural elements built using timber, which is subject to damage from fungal decay and woodworm.
Sometimes sections of timber can be retained, so the whole length does not need to be replaced. This is done using a technique known as a timber resin splice (TRS) system, where a new section of timber is bonded to the existing section using mechanical fixings and epoxy resins. A splice is used to surround the repair allowing the resin to bond. Because these are inserted on site, it can minimise disruption and reduce the costs of replacing the whole section of timber.
This technique is particularly popular in buildings or properties where the original appearance of timber is required, avoiding unsightly steel plates and bolts. The new timber is stained and the repairs are concealed, allowing for the repair to match the original aesthetics. In listed or historic buildings, this repair process may be the only method acceptable to gain listed building consent.
Timber Repair Surveys
In order to fully understand the extent of the damage, and source of moisture that is causing timber issues, it’s important to first have a damp and timber survey carried out by a qualified surveyor. They will fully investigate the premises in order to determine the source of the damp problem and assess the condition of timber and the extent of any damage. Timber decay is often hidden in hard to reach areas, such as sub floor voids, behind panelling or in roof spaces.
Depending on the timbers requiring replacement, the input of a structural engineer may also be required.
The surveyor will detail their findings in a survey report, laid out in an easy to understand manner, with recommendations for treatments, if required. If timber resin repairs are required they will be detailed in the survey report, along with the steps to be taken throughout the repair process.
Our surveyors are CSRT or CSTDB qualified and have extensive experience dealing with all types of properties, meaning they understand the architecture of buildings local to you, and can correctly identify damp and timber problems to strict industry standards. We can provide extensive advice and solutions for domestic home owners, commercial clients, social housing providers and for listed or historic properties across the UK.
Timber Resin Repair Installation Process
Rentokil Property Care have a number of trained and experienced technicians with experience installing timber resin splice systems, and are capable of carrying out insecticidal and fungicidal treatments where required.
Throughout the process our technicians will carry out repairs to the highest industry standards. They will talk you through the process from start to finish, while ensuring that you face minimal disruption. Our technicians are equipped with protective floor coverings, Hilti dust extraction units and vacuums in order to keep your property as clean and tidy as possible.
Preparation on Site
Replacement timber sections are made to measure for each TRS location, and often made off site, making them suitable for a range of projects. The first step is always to remove the source of damp that has been causing problems, this is done through damp proofing, ventilation improvements or fixing building defects. If these are not carried out, timber could continue to be at risk of further timber decay.
Where large sections of timber are cut back and removed they are first supported, before the decayed timber is removed. The technician will then cut slots into the existing timber for the mechanical fixings to be inserted to form the bond using resin.
Installation of the new section
The new section of timber with mechanical fixings is readied, while the beam ends are wrapped in damp proof membrane to protect them where they are in contact with masonry.
It is put in place by bringing together the new and old sections, allowing the mechanical fixings to slide into the pre-cut channels in the existing timber, to provide a weight bearing joint.
Epoxy Resin is Applied
Once the timber is in place, resin is then applied into the pre cut channels to create a seamless concealed joint. Once the resin has cured the repair will retain the original strength of the timber, and can handle compressive loads. Where required, we will reinforce weak joist with support timbers and repair stress cracks, splits and fissures.
Matching the Original Aesthetics
Once the resin has fully cured, it can then be decorated to match the original timber. This will make the repair indistinguishable, while retaining original strength long term.
Because of this these systems are useful for listed or historic properties where specifications dictate the aesthetic features of the original timber are required.
Benefits of Timber Resin Splice (TRS) Repairs
-
Minimises disturbance: - By removing the need to replace whole sections of timber, this means that existing plasterwork, ceilings and floors may not need to be removed to repair the damaged section.
-
Cost effective: - Timber resin repairs can be a more cost effective repair than replacing the full section of timber, and can be repaired quicker. Some large section timbers are almost impossible to obtain in like for like materials at economic value and therefore TRS becomes the most viable option.
-
Strong repairs: - The bonded resin and mechanical rods create a repair that retains the original strength of timber, while being able to handle compressive loads.
-
Original aesthetics: - The repair joint is concealed, creating a seamless finish. This makes it a popular choice for repairs on historic and listed properties where visible steel plates or bolts are not wanted.
-
Environmentally Friendly: - These repairs can save existing timber that would otherwise need to be completely replaced.
