‘Dipping’ the sub-base ensures you’ve got no humps or hollows in your MOT type 1 sub-base….. When the sub-base is levelled to the correct gradient and compacted, this allows an even depth of mortar bed of approximately 40mm which allows even compaction of the mortar bed, even compaction with no weak points. #landscapers #landscapingdesign #landscaping #landscapeindustryspecialists #LandscapersOfInstagram #paving #sitetraining #landscapingtraining | Gareth Wilson Garden & Landscaping Consultant
