Bedding mortar typically has high-performance characteristics, setting very fast and gaining rapid strength. This makes it ideal for use on roads and motorways, where maintenance work needs to be completed quickly with minimal disruption to traffic. Fortunately, there are a number of ways that bedding mortar can be used to restore the strength and stability of ironwork.
Securing ironwork
Ironwork, such as manholes and road gullies, are constantly exposed to the impact of traffic. Whilst designed to be load-bearing, it is not uncommon for the concrete around the ironwork to crack. This results in the ironwork being able to move, which can significantly increase road noise when in contact with traffic. If poorly maintained, this can lead to the concrete breaking, causing failure of the ironwork.
By using a high-performance bedding mortar mix, such as the UltraCrete M45, emergency works can be carried out to secure the ironwork. With this product, roads can be reopened to traffic in just 45 minutes, minimising disruption.
Repairing collapsed brickwork
Over time, the brickwork chamber of a manhole can degrade and collapse. This is particularly common where ironwork is exposed to high levels of traffic, such as the motorway. If repair work is not quickly completed, this can lead to further cracking and breaking, creating an uneven and unsafe surface for traffic.
Reinstating brickwork around a manhole requires a rapid strength bedding mortar, such as the UltraCrete M60, which is suitable for use with all access covers.
Replacing sand/cement mix
Whilst not commonly used anymore, sand and cement mixes were previously a popular choice for ironwork installations. However, sand and cement mixes have typically low tensile strength and are not considered a durable solution for ironworks. When the sand and cement mix inevitably cracks, it can cause the ironwork to become loose and create a traffic hazard.
When replacing sand and cement, use a fibre-reinforced bedding mortar such as UltraCrete M60F, for durability and longevity.
