Bedding Mortar Consumption Calculation
The calculation for bedding mortar is straightforward and may be assessed on the basis of a conversion factor of 1.8 (if not applying a factor for waste) or 2.0 (if allowing nominal 10% waste).
Using a Conversion Factor of 1.8 - 2.0 the following simple rule can be applied:
30 mm deep bedding requires 56 - 60 kg / m²
40 mm deep bedding requires 72 - 80 kg / m²
other depths pro rata.
A useful method, if assuming 10% waste, is to multiply the depth of the bedding mortar in millimetres by 2, to arrive at the consumption in kg/m²
