Simply Paving Building Materials MOT Type 1
MOT Type 1 provides the perfect sub-base for all driveway and patio projects. The MOT Type 1 we offer is delivered in large bulk bags. One bulk bag will cover approximately 8 square metres (coverage is calculated assuming a depth of 50mm).
How deep should MOT Type 1 be?
It is usual to lay MOT Type 1 at a compacted depth of 100mm for most patio projects and at a compacted depth of 150mm for most domestic driveways. Compaction should be achieved using a wacka plate. MOT Type 1 is used to stabilise the ground prior to laying paving and also allows for drainage.

How much ballast and cement do I need calculator?
ballast calculator for concrete:-quantity of ballast for 1m3 concrete is calculated as follows, ballast quantity = 5/6 × 1m3 = 0.833 m3, we know weight of ballast = volume × density, so weight of ballast in kg = 0.833m3 × 1750kg/m3 = 1458kg, if weight of ballast bag is 25kg, then number of bags of 25kg ballast as 1458/
