However, poured concrete walls can be seen almost everywhere today apart from the massive use of concrete sleeper retaining wall in Brisbane.
However, it requires a pro-skill to form a perfect wall, and there are chances that a few things may go wrong in case of residential landscape retaining walls. And, if you want to build a strong concrete retaining wall that will do more than reshaping the soil, you should consider pouring the wall, instead of using the concrete blocks.
Here are a few steps a pro in retaining wall builder takes:
- Measure and mark footing locations: Plan for a retaining wall by marking the area with paint and measuring tape, and chalk out the location for footings. Professional make proper measure and re-measure it before creating the paint marks on the ground.
- Dig the Footing: When it comes to raising the retaining walls up to a certain height, the first thing professionals do is dig the footing area for retaining wall. Before they start, they consult with a local building inspector to determine how deep the footing is required according to the retaining wall height.
- Form Building: Before pouring the retaining wall, experts build the forms. To do this, they drive the stakes into the ground across the area, where footings are needed to install. The thickness of retaining walls you need will determine how much spacing you need between the stakes.
If you are pouring a retaining wall that will be 12 inches thick, the wooden plank used for form should be 1-1/2 inches thick. Builders also need to make sure that the stakes are long enough to support the form for the height of retaining wall. Next to it, the wooden planks are screwed from the inside that goes out to the stake.
- Place the Rebar: Rebar is used as a tension device that strengthens the concrete or masonry structures. The pattern you see on the steel bar itself is meant to create a superior bond with the concrete, which is strong in compression and creates tension over the long run.
- Mix Concrete: Following the instructions on the bag of cement, experts mix the materials accordingly, dump it into the wheelbarrow.
- Pour the Retaining Wall: The mixture is rolled on in the wheelbarrow, and the cement mixture is poured into the footing and form area. As soon as the forms are full, builders smooth the top of the wall and let the cement fully cure.
Lastly, before you begin, ask your contractors to check with the local building inspector’s office to find out how much rebar is required in retaining walls, how it should be laid and spaced.
