How to Use Concrete Form Tubes: 14 Steps
Step 1: Choose the Right Size Concrete Form Tube
Before starting your project, it’s essential to choose the correct size of concrete form tube. These tubes come in different diameters and lengths, so pick one according to your specific needs.
Step 2: Mark the Location and Measure
Before you start with the form tubes, mark the location where you’ll install them. Next, measure the length of the tube required for each location.
Step 3: Cut the Concrete Form Tubes
Using a handsaw or circular saw, carefully cut the tubes according to the measurements taken in step 2.
Step 4: Prepare the Ground
Ensure that there is a level surface ready for placing the tubes. Remove any debris or rocks that may interfere with proper tube placement.
Step 5: Dig Holes for Tube Placement
Dig holes with a diameter larger than that of your form tubes. The depth of each hole should be a few inches deeper than half the length of the tube.
Step 6: Place Gravel in the Hole
Pour gravel into each hole up to approximately 3 inches deep. This provides drainage and stability for your concrete form tubes.
Step 7: Set up Wooden Stakes
Place wooden stakes around the periphery of each hole at regular intervals. Hammer them into place and make sure they’re secure. The stakes will be used for aligning and securing your concrete form tubes.
Step 8: Position Your Concrete Form Tubes
Place your concrete form tubes within each hole, centering them on top of the gravel base. Make sure they are level and plumb before moving on to step 9.
Step 9: Secure Your Tubes With Wooden Stakes
Using screws, nails, or brackets, attach your concrete form tubes to their corresponding wooden stakes. This ensures proper alignment during pouring and prevents shifting.
Step 10: Double-Check Alignment
Before pouring the concrete, double-check that your tubes are level and aligned properly. Adjust the tubes if necessary using the wooden stakes.
Step 11: Create Braces With Lumber
Cut pieces of lumber long enough to serve as braces for your tubes. Attach one end to the top of each tube and the other end to a stake driven into the ground at a 45-degree angle. The braces provide extra support during the pouring process.
Step 12: Pour Concrete
Pour the prepared concrete mix into each form tube slowly and evenly. Make sure to shake the forms or tap them with a rubber mallet to ensure there are no air bubbles trapped inside.
Step 13: Cure the Concrete
Allow the concrete to cure for at least 24 to 48 hours, or according to the manufacturer’s recommendations. Do not remove any braces or stakes during this time.
Step 14: Remove Form Tubes
Once your concrete has fully cured and hardened, detach the wooden stakes and carefully remove each concrete form tube by cutting vertically along its seams with a utility knife.
And there you have it! Now that you know how to use concrete form tubes, you can complete your projects with ease and confidence. Always remember to practice safety precautions while working with concrete, including wearing appropriate protective gear and taking breaks when needed.
