Pad: Concrete Or Crushed Stone?

It's a shame you can't do it yourself. We just got some crushed stone to put under our concrete pad as well as to do a patio around it and it was only $133.00 for the crushed stone and the sand we need for the pavers as well. The concrete we did ourselves as well, borrowed a friends concrete mixer.

Crushed Stone

It serves as a stable base material for construction projects like roadways and building foundations, enhances concrete and asphalt durability, and aids in landscaping for pathways and drainage. Additionally, crushed stone is crucial in railroad construction as ballast and in erosion control to stabilize slopes and prevent soil movement.
