Materials, products and services define how our world is built and is why Leviat is gearing up to sponsor and showcase an incredible line-up of innovative solutions from its world leading range of connecting, fixing and anchoring products at Futurebuild 2023. Walls that are prone to tensile forces are needed to be reinforced, and both horizontal and vertical reinforcement is required. Reinforcement mesh is a flat product made of either stainless or galvanised steel. Unlike ladders, the mesh features a lattice crossing of thin steel wires, creating a mesh. The longitudinal steel wires are flattened to ensure good mortar cover even when lapped or used with wall ties. Cross wires are welded in the same plane as the main wires at 450mm centres. Having the right reinforcement is crucial for any masonry construction. There are many options available, but the most common are ladders or mesh.

Bed joint reinforcement can also be used near the top of the structural walls abutting concrete roofs and to provide additional strength to parapet walls. Whether your job needs a reinforcement ladder or mesh should be specified by the architect or a structural engineer. With so many positives, it’s no surprise they remain the number one choice for external walls to this day. Ladders should be used at no more then 300mm centres. For standard walls, this usually means every course.

It plays an important role in the earthquake resistance as compared to the reinforced cement concrete. Ladders can sometimes be preferred due to their shape, which allows additional masonry reinforcement - such as vertical bars - to be inserted. LABC Warranty also recommends ladders over mesh for openings greater than 1.5m in width, such as above and below large windows.

A common form of masonry reinforcement for large builds is vertical steel bars which fit inside the wall. However, many builds will also have one of these included: However, both products do similar jobs, so there are many circumstances where either could be used. As mentioned before, the architect or structural engineer should specify which is required. Available in both grade 304 and 316 stainless steel, Ancon masonry reinforcement provides the greatest corrosion resistance and life-cycle costing benefits. LengthThe vast majority of masonry construction will require reinforcement due to the height of the walls and the potential impact of factors such as wind over time. We will endeavour to deliver on the day specified, but cannot be held responsible should delays occur due to circumstances beyond our control. Please try and avoid arranging for tradesmen to begin work before the materials have arrived as D W Nye Ltd will not be held liable for any costs incurred as a result of not meeting a delivery date.

Standard AMR is available in three widths - 60, 100 and 150mm - and can be used in wall widths from 90mm to 190mm. Galvanised steel mesh should not be used on external wall leaves. Here, stainless steel should be used. It is necessary to provide horizontal reinforcement at your every three to four-course, which consists of the Steel mesh. In walls which have door and window openings, bed joint reinforcement can reduce the frequency of control joints. Reinforcement should be provided in the first and second courses above and below all openings and should extend no less than 600mm either side of the opening. How to Building Construction Process Step by Step – Follow 26 Step for Building Construction ProcessThe Reinforcement should be effectively surrounded by the mortar cover of 15 cm to 25 cm. It will help to protect the Reinforcement against corrosion. Position the mesh within the masonrybed joints, providing a minimum of 25 mm cover to external faces. Position the mesh within the masonrybed joints, providing a minimum of 25mm cover to external faces. The use of Ancon reinforcement referenced AMR/S/D3.5/W60 is normally recommended at vertical centres no greater than 300mm, usually every course or every other course depending on the height of the masonry unit. The illustration below uses a 215mm unit height.
