Frequently asked questions

How do I calculate concrete volume?

Volume = Length × Width × Thickness. Convert to cubic yards: divide by 27 (since 1 cu yd = 27 cu ft). Add 10% for waste.

How many bags of concrete do I need?

A 60-lb bag yields ~0.45 cu ft. Divide your total cubic feet by 0.45 to get the number of bags needed.

How do I convert my estimate to a client quote?

Use Tregovia's estimates module to enter materials, labor, and markup — then send the quote as a professional PDF and convert to invoice on approval.
