Sub Base & Hardcore

At Willis & Ainsworth we pride ourselves in supplying all types of Sub Base and Hardcore materials for any job. We have access to both primary sub-base such as Limestone and Granite based materials and Recycled materials such as crushed concrete (6F5) or Type 1 Recycled. 

Primary vs. Recycled

There is always the question of Primary Sub Base vs. Recycled Hardcore.

Some differences should be mentioned in the product description but the main point for most products is the price. This has the most impact on larger 20 tonne loads or big jobs that need 100s-1000s of tonnes. We would suggest sticking to primary materials or the material specified by the surveyor, unless you or your groundworker / builder really know what to expect with Recycled products. Every producer has different standards when producing recycled materials and only products that are tested comply to a certain standard.

Sustainable Urban Drainage Systems (SUDS)

Materials that comply to "SUDS" are a more recent product within the aggregate industry. These are the materials that conform to Marshalls, Formpave, AquaPave and AquaSlab paving solutions laying guidleines. There is also MOT Type 3 (DOT or MOT type 1 X) this material is what is the suggested base material to all new drives. We also offer 2-6mm & 20-4mm limestone for laying these paving slabs.
