Barn, Somerset - overloaded tie beams in a barn now carrying heavy clay tiles on the roof (had been a thatch and then galvanised sheeting).

Loft Conversion, Newton Abbot - maximum ridge board to be 12" x 4" (300mm x 100mm), not strong enough to meet Engineers specification.

Upgrade the Beam or Joist - cut a slot, or slots, along the length to within about 40mm of the base and bond in BS4449 High Tensile Rebar with Structural Epoxy Pouring Resin. This is know as a 'modified flitch' design and approximately doubles the stiffness of a typical timber, in bend.

Independent Engineering calculation service available, £300 per beam, Indemnified.

New timber component in place - note bars in slots

Farmhouse, Crediton - under strength timber joists for proposed use as a first floor bedroom. These were slotted from above and Rebar bonded in using Structural Epoxy Pouring Grout.

Cut out the decay and either:

1. Cut off the end completely and fit a Timber-Resin Splice, priced and manufactured to fit the exact size and timber type.

2. Build a box around the missing part, fit Rebars to extend into the sound part and fill with Structural Epoxy Pouring Grout.
