Lime mortar cuts time and costs

MATERIALS

BRICKIES could boost productivity and cut costs by binning sand and cement mortar in favour of more traditional lime mortar.

Research by materials giant Tarmac with members of industry bodies the Guild of Bricklayers and Brick Subcontractors Association has shown that lime mortars can offer greater productivity than sand and cement mortars.

Yield can be raised by up to 35 per cent, and trials demonstrated that the improved workability of lime mor tar can boost productivity by up to 29 per cent, saving 2.5 hours in an average eight-hour day.

Over the course of two trials brickies laying using lime mortar managed to set 32 per cent more bricks than their sand cement mortar counterparts, a difference which rose to 35 per cent du r ing the second t r ial.

Darren Waters, Tarmac mortar director, said these savings were just the tip of the iceberg.

He said: 'Switching to using lime mortar as standard could provide cost savings of up to 35 per cent and that is before potential maintenance cost savings are taken into account.' Malcolm Thorpe, trustee from the Guild of Bricklayers said: 'The benefits of lime mortar are well known.

'Due to its durability, cost savings could continue to be appreciated via reduced maintenance costs.'
