The reinforcement of timber elements using fibre reinforced polymer (FRP) plates or rods is widely accepted as an effective method of increasing the strength and stiffness of members, while at the same time reducing the inherent variability in properties. There are many options to choose from in relation to the FRP material and one of the least documented is basalt fibre reinforced polymer (BFRP). BFRP is the reinforcement chosen in this project due to its superior properties over more commonly used FRPs. Twenty low-grade Irish glued laminated beams are reinforced with two near surface mounted BFRP rods. They are tested in four-point bending in both their unreinforced and reinforced state and the percentage increase in bending stiffness is calculated. The average increase in local bending stiffness is 16.30% with a standard deviation of 1.65%. In addition, the variability in the bending stiffness of the beams is reduced after reinforcement.
