Stabilise cracked walls effectively, ensuring strength and controlled movement for lasting results
When a wall cracks, it is no longer structurally one wall. It is two walls close to each other, able to move independently, but unable to share loads across the crack. Bar Flex can be used to stitch across a crack to reconnect the two sides.Â
A common mistake with cracked walls is to only fill the cracks. While this is an aesthetic solution, the wall is only held together by the often inadequate bonding strength of the filler and will likely crack again in the future. Furthermore, in cases of seasonal movement, filling the crack can exacerbate the issue as it prevents the crack from closing naturally and will ratchet the crack further open in the future.
Another mistake is to use a rigid material like rebar to stitch a crack. This stops natural building movement and will move the crack to another location.Â
By contrast, Bar Flex works with the building rather than against it by allowing some controlled Movement.Â
Crack stitching on its own solves a common, but relatively minor, issue and only once the cause of the movement has separately been identified and repaired.
Solid crack repair starts with good advice! During our first visit, we will assess the cause of the cracks in your façade together with you. Based on our findings, we will create a non-binding repair plan with an associated quote, detailing what needs to be done and how we will proceed.
Target Fixings has over 20 years of experience in developing, producing, and installing crack repair systems. Our Bar Flex and Bond Flex system offers the flexibility needed to accommodate any movement in the masonry.
Before installation, some horizontal joints are grooved, after which the Bar Flex bars are fixed using the Bond Flex anchoring mortar. After a few days, the joints can be sealed with any desired mortar, making your wall almost invisible after repair.
This month, our Warsaw team had the privilege of undertaking a significant structural project on a stunning historic property near the city. This case study highlights our expertise in historic building repair and preserving the architectural heritage construction of Poland.
