For optimal stability and durability, it’s best to lay slabs on a sand and cement mix or a concrete base rather than just sand alone.

Why use sharp sand for laying slabs?

Sharp sand is used for laying slabs because of its angular particles, which interlock to provide better stability and prevent settling.

Do you lay slabs on sharp sand or building sand?

Sharp sand is preferred for laying slabs due to its better interlocking properties compared to building sand.

Should I mix cement with paving sand?
