BIOKIL. Bower Beams – galvanised steel joist-end replacement

The Bower Beam method makes joist-end replacement quick and simple: cut the decayed joist end back to sound timber, treat it with preservative, then fix a Bower Beam to the joist and into the existing wall socket. The joist stays as strong as before and is held clear of the damp wall.

Key benefits

No new wall pockets or joist hangers – uses the existing joist pocket
Replace joist ends one at a time without supporting the whole floor
Fits joists 50–152mm (2–6") wide; all fixings included
2mm KHR steel with a supergalv finish for durability in damp conditions
Compact – easy to handle in confined sub-floor spaces

Sizes

6" (BM6) – for joists cut back up to 150mm; 4 pilot holes per joist end
9" (BM9) – for joists cut back up to 230mm; 6 pilot holes per joist end
17" (BM17) – for joists cut back up to 430mm; 10 pilot holes per joist end

Fitting in brief

Support the floor if replacing more than one joist end at a time, and cut back to sound timber.
Clean and level the joist pocket, wire-brush the cut end and treat with preservative (e.g. Ecobor 20).
Place the two "L" sections either side of the joist, sliding the ends at least 100mm into the pocket, and locate with the galvanised pins.
Drill 5mm pilot holes 30mm deep through the large holes and fix with the galvanised coach screws (14mm spanner).
