How to lay paving slabs on sand?
An alternate way of laying paving slabs is to use a sand and gravel sub-base. Sand is affordable and easier to use than concrete while still making a secure base.
Building sand is not used for the laying of block paving or paving slabs unless it is combined with cement and even this mixture can be too soft to lay paving slabs upon. This is because of the fine nature of the sand. If you use soft building sand to lay block paving upon it will eventually lead to the paving sinking.
Differences between sharp sand and building sand
Also known as 'grit sand' or 'concrete sand', sharp sand is coarser than builders sand thanks to its larger particles. Having a larger grain size means sharp sand is slightly heavier, giving the mortar more strength yet making it less flexible to work with.
