Concrete Layouts

Concrete Pad Layout Tool for Concrete Contractors

A concrete pad drawing answers the three questions every slab quote needs: how big, how thick, and where. SiteBuildHub Draft lets you draw the pad outline at true size, mark control joints, note thickness and reinforcement, and export a dimensioned concrete pad layout with the quote.

Draw the pad layout

The concrete pad template loads a 36' × 26' pad with control joints, a thickness note, and two dimension lines. Resize the outline to the job, drag the joint lines to your spacing, and update the note — '4" slab, rebar at 24" on center' or whatever the job calls for.

For patios and pads that meet a structure, add the house or garage wall as a line so the placement is unambiguous. L-shaped and notched pads are quick work for the polygon tool.

  • Pad outline with true dimensions
  • Control joint layout
  • Thickness and reinforcement notes
  • Adjacent structures for placement context
  • Square footage for volume calculations

From area to yardage

Select the pad shape to read its square footage, multiply by thickness for cubic feet, divide by 27 for yards — the drawing gives you the area number that starts the math, documented where the crew and the supplier can both see it.

Joint spacing drawn to scale also keeps the finishing plan honest: everyone sees where the cuts land before the pour, not after.

Site checks before the pour

Slabs and pads can trigger permit requirements, setback rules, and frost-depth specs depending on size and use. Verify local code, and arrange utility locates before any excavation or grading. SiteBuildHub Draft documents the plan; licensed professionals and local authorities govern what's buildable.

Frequently Asked Questions

Can I calculate concrete volume from the drawing?

The drawing gives you exact square footage from the pad shape. Multiply by your slab thickness to get volume — the area number is the part worth documenting, and it's on the drawing.

Can I show control joints?

Yes. The template includes joint lines you can move, and you can add more with the line tool so the cut layout is agreed before the pour.

Does it handle L-shaped pads?

Yes. Use the polygon tool for L-shapes, notches, and angled pads. Area calculation works on any closed shape.

Do small pads need permits?

It varies — many municipalities exempt small pads but regulate larger slabs, garages, and anything with footings. Check locally before you dig, and always get utility locates.
