Step 1: Gather the Materials
Before starting any construction project, gathering the necessary materials is crucial. Here is a list of the items you will need:
- Bricks (preferably fire bricks)
- Mortar mix
- Trowel
- Masonry saw
- String
- Level
- Measuring tape
- Bucket for mixing mortar
Step 2: Prepare the Foundation
Start by preparing a solid foundation for your arch. Ensure the ground is level and remove any debris. Lay a layer of mortar on the ground, slightly wider than the planned base of the arch. This mortar bed will provide stability.
Step 3: Set the Center Line
Take a string and stretch it across the width of the foundation. This string will serve as a guide for setting the center line of the arch. Ensure it is level and securely anchored on each side.
Step 4: Lay the Initial Course
Begin building the arch by laying the initial course of bricks. Apply mortar to the underside of each brick and position them along the center line. Use a level to ensure the bricks are perfectly aligned and levelled.
Step 5: Construct the Arch
Continuing from the initial course, lay additional courses of bricks, making sure to slightly angle each brick towards the center. This angling will create the curved shape of the arch. Apply mortar generously between each brick to ensure a secure bond.
Step 6: Trim the Bricks
As you reach the top of the arch, you may need to trim some bricks to fit the desired shape. Use a masonry saw to carefully cut the bricks, ensuring a precise fit. Always wear protective gear when using power tools.
Step 7: Complete the Arch
Continue adding courses of bricks until you reach the desired height for your arch. Remember to alternate the placement of bricks to maintain stability and strength. Use a level frequently to ensure the arch remains levelled throughout the construction process.
Step 8: Add the Keystone
Finish off your masonry arch by adding the keystone – the center brick at the top of the arch. Apply mortar to the keystone and carefully position it to complete the arch’s shape. The keystone is essential for distributing the arch’s weight evenly.
Step 9: Cure and Maintain
Allow the mortar to dry and cure according to the manufacturer’s instructions. Once the arch is fully cured, periodically inspect it for any cracks or signs of damage. Perform regular maintenance to ensure the long-lasting beauty and stability of your masonry arch.
Now that you are equipped with the knowledge of building a masonry arch from scratch, don’t hesitate to embark on this rewarding construction project. With careful planning and attention to detail, you too can create a stunning masonry arch that will stand the test of time.
