Building a simple brick wall may seem daunting at first, but with the right tools and techniques, it's a task well within reach for the average homeowner. Not only is it a cost-effective way to enhance your property's aesthetics, but it's also a great way to gain a sense of accomplishment. So, let's dive into how you can build a simple brick wall that will last for years.
Before we begin, it's crucial to ensure that you have all the necessary tools and materials. You'll need bricks, mortar, a trowel, a level, a tape measure, goggles, and work gloves. Safety is paramount when working with bricks and mortar, so ensure you have appropriate attire, including a sturdy hat to protect your head from falling debris.
Prepare Your Workspace & Materials
Start by clearing the area where you'll be building the wall. Ensure the ground is level and stable. If not, consider laying a concrete base to provide a solid foundation.
Next, inspect your bricks. Each brick should be uniform in size and shape. If you find any that are damaged or irregular, remove them from your work area to avoid compromising the integrity of your wall.
Calculate the Number of Bricks Needed
Before you begin, it's essential to know how many bricks you'll need. Measure the length and height of the wall you plan to build. Most bricks are 215mm long and 65mm high, but the thickness can vary. Multiplying the wall's dimensions by the mortar joint thickness (typically 10mm) will give you the approximate number of bricks needed.
Remember, it's better to have a few extra bricks than to run short during construction. Also, factor in wastage due to damaged or broken bricks during the building process.
Prepare the Mortar
Mixing mortar is a crucial step in building a brick wall. The mixture should be one part cement to six parts sand. You can adjust this ratio depending on the strength required, but for a basic garden wall, this ratio is sufficient.
In a wheelbarrow, mix three shovels of dry cement with 18 shovels of dry sand. Gradually add water while mixing until you achieve a stiff, cohesive mixture. The consistency should be similar to peanut butter.
Lay the First Course of Bricks
The first course, or layer, of bricks is the most critical. It dictates the alignment of subsequent courses, so it must be perfectly level. Start by laying bricks along both ends of the wall, ensuring they are perfectly plumb (vertical) and level.
Use a spirit level or a laser level for precise measurements. Adjust the bricks as needed, adding or removing mortar beneath them until they are level. Once both ends are set, lay bricks along the length of the wall, maintaining a consistent joint thickness.
Continue Laying bricks in Bond Pattern
For a simple brick wall, the stretcher bond pattern is commonly used. In this pattern, each course of bricks is laid with its end resting on the stretchers (the longest side) of the course below. This creates a strong, interlocking structure.
Begin by laying the second course, staggering the bricks so that they rest on the central portion of the brick below, not the joints. This forms what's known as a soldier course. Continue laying courses in this alternating pattern, ensuring each course is level and plumb.
Adding Recessed Bricks for Strength
Every fifth or sixth course, include a header course - where bricks are laid on their ends, with their shortest side facing out. This adds strength and stability to your wall. Recess these bricks slightly to create a flush finish.
To recess a brick, lay it on its side, then cut out a small section of the mortar joint above it. Plant the brick in this space, tapping it gently to ensure it's level. Fill any gaps with mortar and smooth the outer face to create a flush finish.
Finished? Consider These Post-Construction Tips
Once your wall is built, allow the mortar to cure properly. This usually takes around 28 days. During this time, avoid extreme temperatures and rainfall to ensure the mortar sets correctly.
After the curing period, apply a layer of brick sealer to protect your wall from moisture and stains. This will also enhance the wall's color and give it a lustrous finish. Regularly inspect your wall for any signs of damage, and repair or replace bricks as needed to maintain its longevity.
Building a simple brick wall is a rewarding task that requires patience, precision, and the right techniques. With this guide, you're well on your way to creating a wall that's both functional and beautiful. Happy building!
