Platinum Building Chemicals Ltd | Timber Joist Repair
Any joist or beam end in direct contact with a wet wall will eventually succumb to fungal attack and decay (rot) thus losing its strength, it may even break. Should this happen the problem of replacement is expensive and time-consuming.
Bower Beams Joist Repair Plates can be used to effect a quick, cheap and easy but secure and long lasting replacement.
Independent tests have shown that the Bower Beam Joist Repair Plates are capable of withstanding loads in excess of the design loads of the wooden joists they are supporting which will in turn, be isolated from the source of the dampness and further risk.
All of these joist repair plates can be used as timber splicing plates by fastening an equal number of coach screws either side of the splice.
Bower Beams Joist Repair Plates are supplied in pairs, available in 4 Sizes:
BM6 - (W) 100mm x (L) 600mm (Cut back to 6")
BM9 - (W) 100mm x (L) 700mm (Cut back to 9")
BM17 - (W) 100mm x (L) 1000mm (Cut back to 17")
BM17W - (W) 150mm x (L) 1000mm (Cut back to 17")
Coach Screws supplied with each pair.
1. Cut away the affected timber up to the required length from the joist end.
2. Offer up the two halves of the Bower Beam to the joist and slide forward into the socket. Secure with nails.
3. Drill the required number of pilot holes for the coach screws (not opposite each other).
4. Tighten down the coach screws. Note: a blocking piece will be necessary on large cut backs to fasten down the floor boards. Joist widths from 2 inches (50mm) up to 6 inches (150mm) can be replaced by this method. Normal treatment to dispel further fungal attack should be carried out.
