How to Install Interlocking Brick Edging: A Step-by-Step Guide

Installing interlocking brick edging can greatly enhance the aesthetic appeal of your outdoor space while providing practical benefits such as containing soil, defining boundaries, and preventing weed growth. This versatile and durable landscaping element can be seamlessly integrated into any garden design, giving it a polished and professional finish. With careful planning and attention to detail, you can successfully undertake the installation process, transforming your garden into a visually stunning and organized haven.

How to Do Sawtooth Brick Edging?

Sawtooth brick edging adds a charming and decorative touch to any garden or landscape. To begin, dig a trench along the desired edge where you want to install the edging. The depth of the trench should be enough to accommodate the bricks, usually around 3 to 4 inches is sufficient. Once the trench is dug, lay the first brick at a 45-degree angle from the edge, ensuring it’s placed securely in the trench.

Next, continue laying the bricks in a row, buttressing them tightly against each other. It’s essential to use a stringline as a guide to maintain a straight and even edge. Make sure to adjust the height of the bricks as needed to keep them level. As you progress, remember to haunch the ends of each brick, which means filling in the gaps between the brick and the trench walls with mortar. This will provide stability and prevent the bricks from shifting over time.

Allow the mortar to set and dry completely before proceeding with the next row. Repeat the process, placing the subsequent bricks in line with the previous row, at a 45-degree angle. The sawtooth pattern is created by aligning the bricks in an alternating fashion, with the points of each brick interlocking with the previous row. This creates a distinct and visually pleasing edge.

Continue laying the bricks row by row until you reach the desired height for your edging. Take care to maintain the consistency of the sawtooth pattern throughout. Allow each row to set before moving on to the next, as this will ensure the integrity and stability of the edging.

How to Properly Measure and Mark the Trench for Sawtooth Brick Edging

  • Start by measuring the length of the area where you want to install the sawtooth brick edging.
  • Mark the starting point of the trench using a stake or flag to indicate the edge of the brick edging.
  • Using a measuring tape or string, mark the desired width of the trench. This will determine the distance between the edge of the trench and the brick edging.
  • Continue placing stakes or flags along the length of the trench, at regular intervals, to establish the positioning of the brick edging.
  • Using a shovel or trenching tool, dig a trench along the marked path. The depth of the trench will depend on the thickness of the brick edging you’re using.
  • Ensure that the trench has a consistent depth along it’s length. Check the depth with a measuring tool or by placing a straight edge across the trench.
  • Remove any rocks, roots, or debris from the bottom of the trench to ensure a level base for the brick edging.
  • Once the trench is prepared, lay the sawtooth brick edging into the trench, following the marked path.
  • Make sure the bricks fit tightly together and are level with the surrounding ground.
  • Backfill the trench with soil, compacting it gently to secure the brick edging in place.
  • Finally, water the area to settle the soil and allow the brick edging to settle into it’s position.

Continue this process for each stake along the desired path of the brick edging. By stretching and securing the Mason’s line, you create a guide to follow when placing and securing the bricks. This ensures that the edging remains straight and level, providing a professional and polished look to your landscaping project.

How Do You Hold Brick Edging in Place?

Repeat this process for each stake along the edge of the area where you want to install the brick edging. Make sure the line is taut and straight as you go. This will serve as a guide when placing the bricks.

To keep the brick edging securely in place, you’ll need to dig a trench along the edge of the area. The depth and width of the trench should be slightly larger than the dimensions of the bricks you’re using. This will allow room for the bricks to sit securely.

After digging the trench, place a layer of sand or gravel at the bottom. This will help with drainage and provide a stable base for the bricks. Make sure the sand or gravel is evenly distributed and compacted.

Next, begin placing the bricks in the trench, following the guide of the Masons line. Press each brick firmly into the sand or gravel, making sure it’s level with the ground. Use a rubber mallet to tap the bricks into place if needed.

As you lay each brick, check that it’s aligned with the Masons line and level with the neighboring bricks. Adjust as necessary. It’s important to maintain a consistent level and alignment as you go.

Once all the bricks are in place, fill in any gaps between them with additional sand or gravel. This will help stabilize the bricks further. Use a broom to sweep off any excess sand or gravel from the surface of the bricks.

Following these steps will ensure that your brick edging stays in place and looks neat and professional.

Now that you’ve marked the layout and dug the trench for the edging stones, the next step is to add a base for the stones. This will provide stability and prevent shifting over time. Once the base is in place, you can begin placing the edging stones and filling in any gaps between them.

How Do You Install Stone Block Edging?

To install stone block edging, you’ll need a few tools and materials. First, you must mark the layout of your edging by measuring and marking your project area. This will help guide you when digging the trench for the edging stones. Using a shovel, dig a trench along the marked area, ensuring that it’s deep enough to accommodate the stone blocks.

Once the trench is dug, it’s time to add a base for the stones. This can be done by creating a layer of sand or gravel at the bottom of the trench. This base will provide stability and prevent shifting of the stones over time. Make sure to compact the sand or gravel before proceeding to the next step.

Now it’s time to add the edging stones. Carefully place the stone blocks vertically in the trench, ensuring that they’re snugly fit together. Use a rubber mallet to gently tap the stones into place and make any adjustments as needed. It’s important to maintain a consistent height and alignment throughout the entire installation.

Once all the stones are in place, the next step is to fill in the gaps. This can be done by adding a layer of sand or a polymeric jointing sand between the stones. This will help stabilize the edging and prevent weed growth. Make sure to brush off any excess sand or jointing material and wet the area to activate the jointing sand.

Finally, take a step back and admire your newly installed stone block edging. It not only enhances the overall appearance of your landscaping, but it also serves as a functional border, keeping your garden or flower beds separate from the surrounding areas. Regular maintenance, such as weeding and cleaning, will help keep your stone block edging looking great for years to come.
