Cement 40kg

Cement for use with Builders Mix. Recommended 6 parts Builders Mix to One Part Cement as a minimum of dry Mix. Approximately 6 x 40kg Bags cement to 1m³ of Builders Mix. Allow approximately 1/3 more of dry mix for cubic area you wish to concrete. Remove any soft material and replace with Base Course and compact first. Important concrete doesn't make the soft material underneath go hard. This material will stay soft and likely to lead to cracked concrete later.
