Laying the Foundation
The concrete retaining wall in the back of our yard was poured last year and is now ready for the bricks. Bricks from the removal of two chimneys that are over 100 years old are being used for most of the wall.
The first step was to clear out the area in front of the retaining wall. There is a cement footing that the bricks will start on. Concrete Bricks were used for the first three layers. The main reason for concrete bricks as a foundation was the weather resistance, these layers will be under the dirt. Concrete bricks have constant sizes and strength that make for a better foundation. Concrete bricks are also less expensive and I was not sure that I would have enough old clay bricks.
Bricks are versatile construction materials that can be used to make walls. Based on their composition, size, shape, and intended use, they come in a variety of styles.
Types of Bricks
Clay bricks: The most common type are kiln-fired clay bricks. Clay bricks come in a variety of colors, are strong, and offer high thermal insulation. Weathering and aging will change the appearance of clay brick often making the wall more interesting.
Concrete Bricks: Cement, sand, and aggregates are combined to create concrete bricks. They are frequently used for load-bearing walls because they are sturdy and weatherproof.
Sand-Lime Bricks: Sand, fly ash, and lime are combined to create these bricks, which are then steam-cured. They are frequently used for non-load-bearing walls and have a smooth finish.
Engineering Bricks: These have a low water absorption rate and are solid and sturdy. They are generally utilized in circumstances that call for exceptional strength and endurance, including underground construction or regions that are vulnerable to chemical attacks.
Fire Bricks: Refractory ceramics are used to make fire bricks, which can endure high temperatures. They are employed in the construction of kilns, fireplaces, and other heated spaces.
Hollow Bricks: Bricks with cavities or holes are lighter and provide better thermal insulation. They are useful for non-load-bearing walls and also provide better sound insulation.
Perforated Bricks: Small holes are scattered throughout the body of perforated bricks, which improves their capacity for thermal insulation. They are frequently employed in regions with harsh temperatures.
Bullnose Bricks: Bricks with bullnose edges have rounded edges on one or both ends. They are used to make curved walls or windowsills that have smooth edges or for ornamental purposes.
Clinker Bricks: Clay used to make clinker bricks is burnt at a higher temperature, producing a brick that is denser and darker. They are frequently used for facing walls and provide improved strength and durability.
Concrete Blocks: Although not technically bricks, concrete blocks are large precast rectangular units made from concrete. They are easily constructed and frequently used for load-bearing walls.
