Precast concrete padstones are an integral part of today’s building practices. The purpose of a padstone is to form a sound base or pad for a lintel or steel beam (RSJ, Universal Beam, Universal Column, Parallel Flange Channel) to distribute the load onto the surrounding block or brick structure (which would not commonly cope with the high loads imposed).
Generally, precast concrete padstones are manufactured to a 50 N/mm2 compressive strength and they are suitable for the majority of applications where high-strength bearing pads are required.
Our range of concrete padstone sizes are designed to fit most block and pier dimensions. These precast padstones are made from a measured amount of aggregates, cement and water which is premixed and poured into a mould. Ad-mixtures may be added to improve padstone production techniques or the properties of the finished product. Protective clothing, particularly gloves and safety footwear must be worn when handling concrete padstones.
It is recognised within the building industry that it is much faster to use precast concrete padstones than shuttering up and casting your own padstones on site. Pouring padstones in-situ is not a consistent, reliable process due to variations in site conditions and therefore is not covered under the CE regulations for structural products on site. Using a precast concrete padstone manufactured under quality controlled conditions ensures that the load imposed by the steel beam is evenly distributed into the bearing wall, ensuring a safe and sound construction. Loadings should not be imposed upon a concrete pad until it has had a minimum of 7 days to cure. Full compressive strength is reached at 30 days.
Your Structural Engineer should be able to recommend the sizes of the concrete padstones required for your project. SNS is recognised to be a leading provider of precast concrete padstones to the UK building industry with over 30 different padstone sizes normally available from stock. Our range of padstones has been specifically selected to meet the requirements of the trade.
