Step-by-Step Guide to Installing Concrete Spurs

Step 1: Assess the Damaged Fence Post

Inspect the loose fence post to determine the cause of the problem. Typically, loose posts are caused by rot at the base or insufficient anchorage in the ground. Concrete spurs are ideal for posts with rot at the base, as they provide additional support and stability.

Step 2: Choose the Correct Concrete Spur

Concrete spurs are available in different heights, usually between 3ft (0.9m) and 6ft (1.8m). Choose a spur that is slightly taller than the fence post to ensure adequate

support. Consider the thickness of the spur as well – generally, a 3.5-inch (90mm) or 4-inch (100mm) wide spur is suitable for most residential fencing projects.

Step 3: Dig the Hole for the Concrete Spur

Using a shovel or post hole digger, excavate a hole adjacent to the loose fence post. The hole should be at least 18-24 inches (45-60 cm) deep and approximately 10 inches (25 cm) wide. This depth will provide a secure anchor for the spur, while the width will allow room for the concrete mix.

Step 4: Position the Concrete Spur

Place the concrete spur in the hole, making sure it’s vertically aligned using a spirit level. Position the spur so that it’s approximately 2 inches (5 cm) away from the damaged fence post. This will allow room to fix the spur to the post later.

Step 5: Mix and Pour Concrete

Following the instructions on the concrete mix packaging, combine the required amount of water and mix in a bucket or wheelbarrow. The consistency should be similar to that of a thick milkshake. Pour the concrete mixture into the hole around the concrete spur, filling the hole to ground level.

Step 6: Check the Alignment

Use the spirit level to ensure that the concrete spur remains vertically aligned as the concrete sets. Adjust the spur as needed to maintain proper alignment. Allow the concrete to cure for at least 24 hours, or as recommended on the concrete mix packaging.

Step 7: Attach the Fence Post to the Concrete Spur

Drill pilot holes through the fence post and the concrete spur using a masonry bit. Align the holes and secure the post to the spur with coach screws or bolts, using an adjustable spanner or wrench. Ensure the fence post is straight and securely attached to the spur.

Step 8: Final Inspection

Inspect the fence post and concrete spur to ensure they are properly secured and aligned. The fence post should now be stable, with the concrete spur providing the necessary support to prevent future issues.

Costings for Materials

Here’s a general breakdown of the materials’ costs (prices may vary depending on the supplier and location):

Concrete spur: $15-$40 each, depending on height and thickness
Concrete mix: $5-$10 per 50lb (22.7 kg) bag
Coach screws or bolts: $1-$3 each

Installing concrete spurs to secure loose fence posts is a practical and effective solution for maintaining the stability and longevity of your fencing. By following this step-by-step guide, you can ensure a successful installation while also boosting the SEO of your fencing contractor website.

Bonus Tip: Using a Concrete Breaker for Efficient Installation

If you are working with harder ground or need to break up existing concrete in the area where you’re installing a concrete spur, a concrete breaker can be an invaluable tool. Concrete breakers are powerful machines designed to demolish concrete and other hard materials, making your installation process more efficient and less labor-intensive.

Here’s how to use a concrete breaker to assist in the installation of concrete spurs:

Safety First: Before using a concrete breaker, ensure you are wearing appropriate safety gear, such as safety goggles, gloves, ear protection, and closed-toe shoes. Read the manufacturer’s guidelines and follow any specific safety precautions.

Choose the Right Breaker: Select a concrete breaker that is suitable for the size of your project. Smaller, electric-powered breakers are suitable for residential jobs, while larger, hydraulic breakers may be necessary for more extensive projects.

Prepare the Work Area: Mark the area where you need to break the ground or existing concrete, ensuring that there are no underground utilities or other hazards in the vicinity.

Position the Breaker: Place the concrete breaker’s chisel or point at the marked area, holding the breaker at a slight angle. This will help to direct the force of the impact downward, breaking the ground more effectively.

Break the Ground: Turn on the concrete breaker and apply steady pressure, allowing the machine to do the work. As the ground or concrete breaks, reposition the breaker and continue the process until the desired depth is reached.

Clean Up: Remove the broken concrete or ground material and proceed with the installation of the concrete spur, as detailed in the previous step-by-step guide.

Using a concrete breaker can save you time and effort when installing concrete spurs in challenging conditions, making your fencing project more efficient and professional.

Bonus Tip #2: Using Postcrete for a Quick and Easy Alternative to Mixing Concrete

For those looking for a faster and more convenient alternative to traditional concrete mix when installing concrete spurs, Postcrete is an excellent option. Postcrete is a pre-mixed, rapid-setting concrete specifically designed for securing fence posts, making it ideal for this type of project.

Here’s how to use Postcrete when installing concrete spurs:

Safety First: Always wear appropriate safety gear, such as gloves and safety goggles, when working with Postcrete. Ensure that you follow the manufacturer’s guidelines and any specific safety precautions.

Purchase Postcrete: Postcrete is available in 20 kg (44 lb) bags, which can be found at most hardware stores or online. One bag of Postcrete is typically sufficient for setting one concrete spur.

Prepare the Hole: Dig the hole for the concrete spur as described in the step-by-step guide. The hole should be 18-24 inches (45-60 cm) deep and approximately 10 inches (25 cm) wide.

Position the Concrete Spur: Place the concrete spur in the hole and use a spirit level to ensure it is vertically aligned. Maintain a 2-inch (5 cm) distance from the damaged fence post for later attachment.

Add Water: Following the manufacturer’s instructions, pour the required amount of water into the hole. The water level should be about 2 inches (5 cm) below the top of the hole.

Pour Postcrete: Open the bag of Postcrete and slowly pour the dry mix evenly around the base of the concrete spur, filling the hole. The Postcrete will absorb the water and begin to set.

Adjust AlignmentAdjust Alignment: Use the spirit level to check the vertical alignment of the concrete spur, making any necessary adjustments before the Postcrete sets. Allow the Postcrete to cure for at least 20 minutes, or as recommended by the manufacturer, before attaching the fence post to the concrete spur.
