What are Padstones and why should I be using them?.

Padstones, are specialised high-density concrete blocks. 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).

Without padstones, this weight would apply a damaging, crushing force to the blocks directly contacted by the lintel. Padstones however are made of stronger denser stuff than normal blockwork. Padstones are manufactured with 50kn/m2 concrete creating a block that will take a considerable weight from above and effectively distribute it across the blockwork below preventing cracks and structural damage.

What size Padstone do I need?

The size of the padstone will ideally be specified in the engineer’s specification and blueprints.

You cannot cut a pre-made padstone down to size, as this could change the compressive strength of the block.

Our technical team will provide the necessary advice when it comes to padstone design and specification.

Your Structural Engineer should be able to recommend the sizes of the concrete padstones required for your project

Our range of concrete padstone sizes are designed to fit most block and pier dimensions.

These standard sizes are available ex-stock and of course, we are always happy to discuss custom requirements.

Frequently Asked Questions

How strong are padstones?

Padstones are designed to take a substantial amount of weight. This is measured in Newtons and is defined as the amount of force required to move 1 kilogram at the rate of 1 metre per second squared.

Newtons are used to measure a substance’s compressive strength, the amount of force that can be pushed onto an object before it fails. When the force gets too great, the substance could buckle, crack or shatter. Regular concrete mix starts with a rating of about 20.

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.

It takes about 28 days for a padstone to dry, which is what gives it such compressive strength.


How are padstones made?

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.


Can I make my own 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.
