Concrete block walls are easy to build, durable and offer a range of textures, colors and finishes. They can help you solve a drainage problem, level a slope or create an attractive garden wall. These walls can also be used as a foundation for a garage, shed or other structure. However, they must be built on a footing that meets your local building code requirements. In addition, you must know how to properly prepare the site for the wall and install the proper drainage system.
Before you begin construction, you must prepare the site for your concrete block wall by marking out its dimensions with stakes and masonry string. This helps ensure that your wall is the correct length and height. In addition, you must dig a footer that is the correct depth to support your wall. Depending on your project, you may need to install drainage pipes and a foundation drain to control water runoff and prevent erosion.
Once you have the necessary materials, you can begin construction. It is important to take frequent breaks and stay hydrated while working with masonry materials. Additionally, you should wear heavy-duty gloves to protect your hands and a dust mask when pouring mortar or working with masonry. Moreover, you must be careful to avoid back strain by working in an upright position and using your legs when lifting blocks.
Cinder block walls are less expensive than poured concrete, and they’re useful for non-loadbearing garden walls or retaining walls. However, they are also less strong than concrete block walls, and they can be affected by the weather. Consequently, these walls may not be suitable for projects that require an extensive amount of structural strength.
A concrete block wall is a sturdy, long-lasting structure that’s suitable for both residential and commercial applications. These blocks are manufactured in a factory, so they’re more consistent than cast-in-place concrete. In addition, they’re better insulators than poured concrete and can reduce your energy bills.
Manufacturers of concrete blocks make a variety of different designs for their products, including single- and double-cornered units to accommodate windows and doors. You can even find blocks with slotted holes to allow for piping or wiring.
Most types of concrete blocks are made with a solid core and are designed for load-bearing structures. However, some manufacturers produce hollow blocks that have holes that occupy one-quarter to half of their cross-sectional area. These blocks are lighter than solid concrete blocks and can be more easily used for electrical and plumbing work because you can run wires through them.
When you’re building a concrete block wall, it’s important to butter each block before laying it. This will help the mortar bond with the block, ensuring a stronger and more stable structure. In addition, it’s essential to use a mason’s line and spacers between each row of blocks. When you’re ready to start the next course, be sure to put the spacers in place before you lay a new block. This will prevent the blocks from being pulled away from each other due to gravity.
