Timber joists are horizontal components used in framing to carry floor loads. Unfortunately, they can suffer from damage caused by dry rot over time, leading to a loss of structural integrity.\nDry rot is a fungal growth that colonizes and consumes timber, reducing it to a brittle matter. This can compromise the safety of a building and necessitate repairs.\nBower Beams, also known as Joist End Repair Plates, are galvanized stainless steel plates that can be used to restore rotten joist ends.\nIn this article, we will explore the different aspects of Bower Beams, including their functions, applications, sizing, and the damage caused by dry rot.\n \nUnderstanding Dry Rot\nDry rot is a fungal attack that occurs when moisture levels in the timber rise above 18%. This allows the spores of the fungus to grow and colonize the wood.\nIn contrast to other wood decaying fungi, dry rot only colonizes timber that has been exposed to damp conditions for several weeks, typically caused by a plumbing leak, faulty rainwater goods, or poor ventilation.\nDry rot is a destructive force that consumes the timber, leaving it in a brittle and structurally unsound state.\n \n \nDamage Caused by Dry Rot to Timber Joists\nIf timber joists within a building suffer from dry rot, they will begin to decay from the inside out. This process significantly reduces the timber's structural integrity and can lead to significant safety concerns.\nDry rot can cause the timber to crack, split, and crumble, leaving it unable to bear the load it was designed to support.\nA joist with dry rot damage should not go unaddressed as it can lead to building collapse or other forms of structural destabilization. Therefore, prompt repair action is necessary.\n\n \nUsing Bower Beams for Joist End Repairs\nIf a joist has suffered dry rot damage, it is necessary to address the matter as soon as possible to prevent further damage.\nThe first step of the repair process is to cut away the damaged portion of the joist. This could significantly reduce the length of the joist, leading to further problems with structural integrity.\nIn situations where cutting back of the joist has been necessary, Joist End Repair Plates, such as Bower Beams, are utilized to restore the structural strength.\nTo use Bower Beams for a joist end repair, the following steps are taken:\n\n\nThe size of the Bower Beam needed to repair the joist is determined.\n\n\nThe damaged portion of the joist is cut away, and the remaining portion is measured to determine the length of the L-shaped plate required.\n\n\nA Bower Beam is placed onto the timber joist, which serves as the replacement end for the cut-out portion.\n\n\nThe Bower Beam is then secured to the timber joist with the use of the included coach screws provided.\n\n\nThis repair process ensures the joist is structurally sound and restores its original integrity.\n\n\n\n \nSizing your Bower Beams: BM6, BM9, and BM17\nBower Beams are available in three different sizes, each of which can be used for different degrees of structural damage:\n\n\nBM6 Bower Beams: BM6 Bower Beams are suitable for use with joist ends that have been cut back to a maximum of 6 inches. They are the ideal solution for minor repair jobs, where limited damage has occurred.\n\n\nBM9 Bower Beams: BM9 Bower Beams are intended for use with joist ends that have been cut back to a length of up to 9 inches. This size is suitable for more moderate repair jobs, where more substantial damage has occurred.\n\n\nBM17 Bower Beams: BM17 Bower Beams are the largest of the three options, recommended for use in structural repair tasks where the joist end has been cut back to a length of up to 17 inches. This is an extensive repair solution, appropriate for severe cases of dry rot damage.\n\n\nBy providing these various sizing options, Bower Beams enable the best solutions for different degrees of damage.\n \nCarrying Out The Job In Hand\nThe repair process of damaged joists using Bower Beams consists of the following chronological steps:\n\n\nInspection: A comprehensive inspection of the timbers and joists in the building will determine the extent of rot damage and the overall repair work that will be required.\n\n\nCutting Back: The size and placement of the area of dry rot is identified, and the damaged portion of the joist is cut back to an appropriate length.\n\n\nPositioning: The Bower Beams are placed onto either side of the cut joist to provide a stable support system for the joist.\n\n\nFastening: Coach screws are used to attach the Bower Beams to the joist, ensuring that the L-shaped plates are seated appropriately and attached securely.\n\n\nRe-Inspection: The final step is a comprehensive checking process to ensure that the Bower Beams are secured correctly, and that the repaired joist is structurally sound.\n\n\n \n\nConclusion\n\nDry rot is a serious problem that can compromise the structural integrity of timber joists in buildings.\nBower Beams provide an efficient and long-lasting solution for repairing damaged joist ends. No matter the degree of rot damage, these galvanized stainless-steel L-shaped plates are available in three different sizes to suit a wide variety of repair needs.\nBy using the correct size of Bower Beam and following the chronological order of repair, homeowners and building owners can be confident in the stability and safety of their properties.\n \nCopyright Infringement Of Images\nPlease be aware that all images displayed on our website are protected by copyright laws, including any images acquired through licenses from stock photo providers.
