Total novice at this so bear with me.
Have an area measuring 10m x 3.7m that i want to use for a workshop base (75mm deep).
On the ground is already a a mix of 30-40mm mix of what looks like flint chippings which has
a depth of between 40-50mm, so hopefully ok to lay the concrete on top of.
My questions are (having been quoted over £400 for a ready mix delivery!)
1. What quantity of sand and gravel would i need for the area in question?
2. What type of sand?
3. What type of gravel?
4. Would it need any steel mesh?
Thanks in anticipation
