Frequently Asked Questions
How much area does one MOT Type 1 bulk bag cover?
One bulk bag of MOT Type 1 (approximately 1 tonne) covers about 10 square metres at 50mm depth after compaction. For deeper sub-bases of 100mm, one bag will cover approximately 5 square metres.
What's the difference between MOT Type 1 and MOT Type 2?
MOT Type 1 is a crushed aggregate ranging from dust to 40mm stones, providing excellent compaction and load-bearing strength for sub-bases. MOT Type 2 contains larger stones up to 63mm and is typically used for drainage layers rather than structural foundations.
Can I use MOT Type 1 directly under block paving?
No, MOT Type 1 should be used as the sub-base foundation layer. You'll need to add a sharp sand screed layer (typically 25-40mm) directly under block paving for proper levelling and bedding.
How do I compact MOT Type 1 properly?
Spread MOT Type 1 in 100mm layers maximum and compact using a vibrating plate compactor or roller. Add water sparingly if the material is too dry, then compact until no further settlement occurs under the compactor.
Is MOT Type 1 suitable for heavy vehicle access?
Yes, when properly laid and compacted to 150-200mm depth, MOT Type 1 provides excellent load-bearing capacity suitable for driveways with regular car use and occasional heavy vehicle access. For constant heavy traffic, consider deeper applications.
