How to set out string lines for a carport
How to set out string lines for a carport
Overview
When you're building a carport it's important to make sure that the measurements are correct and the string lines are square. Just follow this step-by-step guide and we'll show you how easy it is to do yourself.
Steps
Set up the hurdles
Follow the measurements on the approved plan for your carport. Use the nail gun to attach the first hurdle to the sleeper. The height of the carport slab should be the same as the pavers, so make sure that the posts sit a little bit higher than the slab.
Set your first string line
You need to take two measurements off your wall, from your approved plan, to make sure the string line runs parallel to your home. After marking the first measurement, use the hammer to drive in a piece of timber that you can tie the string line around. Measure the same distance out from your wall and hammer in a nail. Run the string line beyond the required length of the carport but don't tie it off.
Install the second hurdle
Hammer two hurdles into the ground. Use the nail gun to secure a piece of timber to the hurdles. Pull the string line tight so that it touches the nail you hammered in for your string line. Mark that spot on the piece of timber and hammer in a nail. Tie the string line off around the nail.
Mark-off the height of the carport
Use two pieces of wood as a base and a piece of timber to measure the correct height for the carport. Mark this off with a pencil against the fence. Use the nail gun to secure a piece on the fence to mark the correct height.
Check the carport is square
To make sure the carport is square, measure the distance, so that it's parallel to the paving. Mark that distance and hammer in a nail. Run and tie off the string line.
Check your measurements
Measure the distance between the string lines at each end to make sure that they're square.
Run two more parallel string lines
Once the string lines are square, repeat the process to run two more parallel string lines.
Use fluorescent spray paint to mark any possible trip hazards, like the string lines.

Health & Safety
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
