How to Build a Deck on an Existing Cement Slab

Having a deck adds a finished look to any landscaped area. If you have an existing patio, don't let that hold you back from getting the deck you always wanted. In this article you will learn step by step how to deck over an existing concrete slab to add a more natural look to your yard or garden.

Things You'll Need

• Drill Tape measure Saw Screw tip bit for drill Concrete drill bits Concrete anchor screws Lumber (2 by 4 and 2 by 6 is ideal) 2 or 2.5 inch deck screws

Instructions

1. Measure the length and width of the existing patio to determine how much lumber will be required.

2. Cut enough 2 x 4 pieces to run the width of the porch from top to bottom with a spacing of 2 feet between each run of boards.

3. Drill the concrete with the concrete bit where your support boards will lie. Drill every 16 inches to ensure a good hold to the preexisting patio.

4. Screw the support boards down with the concrete anchors into the holes that have been drilled.

5. Measure for 2 by 6 deck boards running in the opposite direction of the support beams.

6. Cut the 2 by 6 boards to length, staggering them in size if you wish.

7. Screw deck boards to support beams using the deck screws until the entire deck has been completed.

Tips & Warnings

• Be sure that when cutting deck boards, that they are either long enough to complete the entire length or that they fall end to end on a cross brace to ensure support. Sealing your deck will help it last through the years.
