What types of crushed concrete do you stock?

We sell lots of types of hardcore materials.

Crushed concrete is one of the most popular materials that we sell. Recycled Type 1 MOT and 6F2 Recycled Aggregates are perfect for environmentally-conscious contractors. The materials come from demolition sites. 

Contractors can also depend on us for crushed granite and limestone. These materials are often found in MOT products. MOT stands for Ministry of Transport. Materials that have this phrase in the title are approved for use in sub bases.

MOT Type 1 near me

So, what is MOT Type 1?

MOT Type 1 hardcore contains limestone and granite. We collect the materials from a local quarry. Our drivers grind the pieces of limestone and granite together to create 40mm pieces. The batch contains chunks that range from dust to 40mm. 

Like all other products that have MOT in the title, Type 1 is perfect for sub bases. The combination of big and small chunks of limestone and granite creates strong bases. Once the sub base has been set, contractors can build heavy formations. MOT Type 1 sub bases can carry heavy loads.

Recycled Type 1 MOT

This is the only type of MOT that we sell that comes from demolition sites. The materials that we collect would otherwise be thrown away. We use industrial machines to collect crushed concrete. The machines might also scoop up materials such as brick and wood. 

Once we have the materials we grind them together. Each batch contains materials that range from dust to 40mm. 

We recommend Recycled Type 1 MOT for sub bases. Sub bases hold heavy formations such as buildings, pavements, and motorways.

MOT Type 2 Clean

What is MOT Type 2?

It contains limestone and granite. We use industrial machines to collect the materials from quarries and grind the pieces down to 40mm chunks. 

Some contractors refer to this product as Clean MOT. We filter all the fine pieces of dust out. Each batch only contains 40mm chunks. 

Contractors can use MOT Type 2 for sub bases and drainage systems.

6F5 and 6F2 Recycled Aggregates 75mm

6F5 Recycled Aggregates are affordable and strong.

We source the materials from demolition sites. There is a range of hardcore materials in each batch. Contractors can expect to find crushed concrete, brick, wood, and any other building site materials in their batch. 

The materials in this batch range from dust to 75mm chunks. 

These materials are sometimes called 6F2 Recycled Aggregates. We recommend them for bulk-fill construction tasks. 

Screened Crushed Concrete Type 1 40mm

Screened concrete has undergone extra manufacturing processes. We collect the concrete from quarries and grind the pieces together. This type of concrete floor screening contains 40mm chunks. Afterwards, we take all the pieces of dust out of the batch.

Once the screening process is complete, this product can be used in a range of construction tasks. Screened concrete is mostly used to create floors for patios and paths.

Screened Crushed Concrete 75mm

This type of screening is a lot like 40mm screening. The only difference is that the pieces are 75mms. 

Likewise, this concrete floor screening does not contain pieces of dust. It is ideal for flooring tasks. 75mm pieces of concrete are good for larger construction tasks that require hardcore materials.

What can I use crushed concrete for?

Contractors use crushed concrete for lots of construction tasks. 

Here are just a few of the ways that contractors use our crushed materials. 

20mm crushed concrete usually supports other batches of concrete that contain larger pieces. By combining big and small pieces of crushed materials, contractors can create strong sub bases. 

MOT Type 1 is designed for sub bases. Once the sub base has been placed and rolled it can support a range of heavy structures. Contractors build driveways, car parks, and even motorways on top of Type 1 sub bases.

Recycled Type 1 MOT is also good for sub bases. It is the only type of MOT we sell that contains recycled materials. 

MOT Type 2 sub bases are strong and durable. We filter fine particles of dust out of the mixture, which makes it perfect for drainage systems. 

6F5 Recycled Aggregates are made for bulk-fill construction tasks. They contain a mixture of hardcore materials. This affordable product is a popular choice for contractors all over Knebworth.  

Will crushed concrete compact?

Crushed concrete will compact under the right circumstances. 

Contractors use our crushed materials for a range of purposes. If contractors use our concrete batches for loose-fill building tasks they will not compact. 

If contractors use crushed concrete for sub bases the materials will compact. Sub bases are a necessary part of lots of formations. Contractors have to lay sub bases for car parks, patios, driveways, and even motorways. The weight of the structure forces the materials in the sub base to compact. 

Some sub bases compact so much that they lose height. Contractors have to add new layers of concrete every year to maintain the required height. 

Do granite and limestone make good sub bases?

As well as crushed concrete, we also sell limestone and granite. 

We sell batches of Type 1 MOT and Type 2 MOT. Both these products contain limestone and granite. We source the materials from quarries and grind them down to size. Type 1 batches range from dust to 40mm. Type 2 batches only contain 40mm chunks. 

Both these products make good sub bases. They contain hardcore materials that create robust structures. They can hold heavy loads such as motorways, car parks, and pavements. 

Type 1 MOT sub bases are especially strong because they contain a range of materials. The small pieces of concrete fill in the crevices that the large pieces of concrete create. 

Does crushed concrete drain?

Crushed concrete, limestone, granite, and other aggregates drain at different rates depending on the circumstances. The ‘flow rate’  tells us how quickly liquids drain through a batch of materials. 

This type of material can be used in a range of construction projects. Contractors often buy it for loose-fill construction tasks or sub bases. MOT Type 2 is used in a lot of drainage systems because it does not contain dust particles. It has a high flow rate.

Products such as MOT Type 1 have lower flow rates. This kind of MOT contains pieces of limestone and granite that range from 40mm to dust. When liquids pass through the batch small pieces of concrete will become dislodged.

Call our team on 01992 635454 for more information.

Will crushed concrete harden?

Most contractors buy our crushed materials for sub bases. As part of the installation process, sub base materials must be rolled. This, along with the weight of the formations that sit on top of the sub bases, forces the materials to harden.

Concrete is already a hardcore material. Once concrete sub bases have settled they have excellent load-bearing qualities. Lots of contractors put motorways and even buildings on top of sub bases. 

Unfortunately, crushed concrete will never be as hard or as smooth as ready mix concrete.

Is crushed concrete toxic?

It is important to understand the health hazards surrounding concrete. It is dangerous to inhale airborne concrete particles. 

We collect concrete from demolition sites. When pieces of concrete break away, particles become airborne. Our machine operators wear protective equipment to minimise the likelihood that they will inhale dust particles. 

Once the materials are on your site there is far less chance that the dust particles will become airborne. However, some particles might be displaced during the installation process. Anyone who works on construction tasks should wear masks and other protective equipment.
