Lowstrength concrete (cement sand and stone mixed by volume in the ratio 1 4 4) is suitable for most garden buildings and it was this mixture that was used. The National Building Regulations state that a straightforward foundation like this one should be constructed using concrete that has a compressive strength at 28 days of at least 10 MPa
More water cement or sand can be added if the mixture is too wet or dry. Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer. Concrete 1 part cement 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar 1 part cement 4 to 5 parts building sand.
