Materials you will need: burlap, cardstock, ruler, X-Acto knife, computer, inkjet printer. 1  Measure out your piece of burlap to 8.5 by 11. Use the X-Acto knife to cut it. 2  Repeat with the card stock. 3  Use the masking tape to affix the burlap to the card stock. 4  Make sure your printer settings are set to Heavy Duty.
Ideally, concrete should be poured when the air temperature is between 50 and 90 degrees Fahrenheit. Cold temperatures slow the concrete-setting process, and when temperatures dip below freezing, the delay allows the water in the mix to freeze before the concrete hardens.
If you decide to pour concrete, I would pour the apron a minimum of seven-inches thick. In my opinion, the concrete mix should be ordered at a design strength of 4,500 pounds per square inch which is slightly stronger than the industry minimum strength standard. It would be very wise to include a grid of half-inch diameter reinforcing steel in the concrete apron.
