For post holes, dig holes with a diameter of 450 mm to the same depth with a concrete cover of at least 100 mm under the pole. Dig two 550mm deep holes for the end posts, pour concrete 600mm from the top, use a spirit level to check the plumb in both directions, and then check that the pole is at the correct height. Sleeper retaining walls go one step further by incorporating additional materials to form the structure, with their name derived from wood or concrete planks, usually built for railways. Sunset Sleepers is an established manufacturer of concrete sleepers from the southeastern suburbs of Melbourne with more than 10 years of experience in the industry.
When constructing a retaining wall, it is important to choose the right type of concrete. The most common type of concrete used for retaining wall poles is reinforced concrete. Reinforced concrete is a mixture of cement, sand, and gravel that has been reinforced with steel bars or mesh. This type of concrete is strong and durable, making it ideal for retaining wall poles.
To begin construction, place the joint posts and then dig holes 550 mm deep and put them into position using a spirit level to plumb, aligning them with the rope and letting them dry. Place and concrete the corner posts, using a construction square to install the sleepers at 90° from the wall. When pouring concrete, it is important to use a vibrator to ensure that all air bubbles are removed from the mixture. This will help to ensure that your retaining wall poles are strong and secure.
Additionally, it is important to use a trowel to smooth out any rough edges on the surface of the concrete. Finally, it is important to use a sealant on your retaining wall poles after they have been installed. This will help to protect them from moisture and other elements that could cause damage over time. By following these steps and using reinforced concrete, you can ensure that your retaining wall poles are strong and secure for years to come.
With proper installation and maintenance, your retaining wall poles will be able to withstand any weather conditions.
