Weight A 1 Â½ inch thick countertop made of standard concrete has an approximate weight of 18.75 pounds per square foot. (Granite is approximately 18 pounds per square foot.) Standard cabinetry will typically support this weight because itâs distributed over a large area.
Thickness can vary between 3/4 or 1-1/4. This roughs out to slightly over 39 SF per slab. Due to the fact that the slab is rough edged the width is important. At 4 1/2 feet wide, figure if you are lucky that you can get two 24 widths out of it for a 24 deep counter.Length too is rough. So figure 8 feet for length. Based on this, you are looking at 32 square feet of flat countertop with no backsplash from it. The thing to remember is that granite slabs vary.ue to the fact that the slab is rough edged the width is important. At 4 1/2 feet wide, figure if you are lucky that you can get two 24 widths out of it for a 24 deep counter.
