AMR-X Masonry Reinforcement
Site trials by Carillion and Reussir demonstrate that AMR-X is a simple, cost-effective way to ensure reinforcement is fully surrounded by mortar.
Unlike standard ladder-type reinforcement, AMR-X features shaped cross wires which elevate the outer longitudinal wires to ensure they are located in the desired location at the centre of a bed joint.
Although good site practice is to bed masonry reinforcement in a layer of fresh mortar, Paul Walmsley, a Masonry Advisor at Carillion, found that ’whether laid post or pre mortar, AMR-X ensures adequate mortar coverage is attained which provides a significant aid to ensuring structural compliance on sites’.
Aware of the time taken to supervise installation of bed joint reinforcement, Alan Phillips, Carillion’s Technical Services Manager says ’using Ancon AMR–X will ensure bed joint reinforcement is accurately installed without compromising on build time’
Alex Cross, a Project Manager for Reussir Ltd (Brickwork Contractors) with over thirty year’s experience, said, ’We built walls using the product in two ways. In the first trial, we applied best practice and pushed AMR-X into a bed of mortar.
On the second occasion we placed AMR-X on dry masonry with mortar applied above, as this is the most common site shortcut which concerns us.
When we took the masonry back down to see the results we found the outer tram wires were located near the centre of a bed joint in both cases.
I am very impressed with the AMR-X brick reinforcement. Ancon has made what appears to be a simple change to the product structure that really delivers results on site.
I have recommended that we use this product as it can eliminate the risk of inadequate mortar bond around bed joint reinforcement’.
Steel reinforcement is located in bed joints to improve the structural performance of a masonry wall.
It is important that the outer steel wires are surrounded by mortar to ensure the designed performance is achieved on site - this guidance is confirmed in PD6697: 2010: Recommendations for the design of masonry structures to Eurocode 6.
The unique design of AMR-X can improve build quality, reduce the requirement for site supervision and accelerate the speed of construction.
It is manufactured from stainless steel wire which is suitable for internal and external walls, and is available in widths to suit brickwork and blockwork.
The cross wires have been designed so the product can be installed either way up.
