Concrete Crusher Hire in Orpington | Using Aggregates to Make Concrete

Concrete is one of the most versatile and, therefore, widely used building materials in the world. From laying property foundations and sub-bases for driveways or patios, to building multi-storey car parks and office blocks, construction companies use it for almost any project. So, whether you’re engaged in demolition works or remodelling your garden landscape, the chances are that you will require concrete removal as part of a professional rubbish clearance service.

As a grab hire company, we collect concrete around Orpington and take it back to our plant in Tunbridge Wells for processing.

Using our concrete crusher hire machinery, we recycle waste concrete into crushed concrete. This is a secondary aggregate, suitable for a wide range of uses. And, as with many aggregates, it is perfect for making fresh concrete.

Whether recycled, manufactured or natural, aggregates play an integral role in the production of concrete. From sand and gravel to slag and crushed stone from rubbish clearances, aggregates make up roughly 75-80% of concrete’s weight and around 60-80% of its volume. While some believe this just serves as filler, many of the properties of concrete are due to the presence of aggregates.

Some of these properties include:


While cement is the most expensive element of a concrete mixture, aggregate is the cheapest. Therefore, the more aggregate you use, the more you lower the cost of concrete production. Furthermore, by using concrete crusher hire machinery to recycle building materials like concrete into secondary aggregates, you can lower the cost even more.

Relying on materials taken from rubbish clearances, and concrete removals on demolition sites around Orpington, also reduces the environmental impact of mining for primary aggregates.


WHW Services Ltd is not just a grab hire company. We are also an aggregate supplier, specialising in the supply and delivery of a wide range of building materials. We therefore understand that using different shapes and textures of aggregate will affect the workability of a concrete mixture.

Materials processed by our concrete crusher hire machinery will be more angular and inconsistent than natural materials like sand and gravel. Recycled aggregates from concrete removals, and demolition sites around Orpington, tend to require more cement to create a workable mixture than when using natural, smooth alternatives. However, they result in a more impressive surface-to-volume ratio and have desirable bonding attributes.

Visual Appeal

Certain construction projects require aesthetic appeal as well as practicality. In such cases, builders will usually opt for exposed-aggregate concrete. They create this mixture by implementing aggregates that possess the right shape, colour or texture to capture the perfect appearance. Natural stones like marble, granite, limestone, basalt and quartz are the best options for this type of concrete mixture.

However, natural stone is far more expensive than using recycled materials gathered from demolition and rubbish clearances, by our grab hire company.

Volume Stability

Aggregates improve the volume stability of a hardened concrete mixture. In recognition of this fact, many construction companies in the Orpington area come to us for concrete crusher hire in tandem with concrete removal. This is so that they can process concrete and other building materials into a secondary aggregate onsite. Recycling such materials saves them from having to order and pay for aggregates to make fresh concrete.  

Whether you are looking for primary or secondary aggregates to produce concrete mixtures, WHW Services Ltd is the only company you need.
