Retainer walls are another term for concrete columns. While they may look simple, they are also quite complicated, requiring many steps to be taken before they are ever installed.
First, a foundation is required to provide an adequate base for the piers. The width of the piers will depend on the depth of the excavated area.
Retainer walls can be installed using either in-place or floating piers. In-place piers are anchored into the ground below and pre-drilled for the wall installation. Float piers are not drilled in the ground but simply stand on the surface.
Concrete piers are cemented into the ground above the excavation to provide a strong, stable structure that is secure from erosion and moisture. The thickness of the material necessary to support the piers will depend on the depth of the excavated area.
Before the concrete columns can be poured, the column must be excavated to the proper depth. It is necessary to have the column drain well so it does not dry out during excavation.
Once the column has been exposed, the next step is to clear away the loose soil and compact it. This is accomplished by scooping the loose soil out from underneath the column.
After the excavation has been completed, the piers must be installed. This is where the crew's skill comes into play.
Contractors may utilize various methods to set the piers and keep them secured. Depending on the method used, this task can take hours or days.
The best way to locate a contractor with expertise is to perform a Google search on contractors in your area with references to their company's reputation. Another method would be to ask friends and family members for recommendations.
The techniques a contractor can use to install retainer walls in Melbourne vary depending on the type of service they provide. The reason for this varies, but typically, the contractor will use piers that have been drilled and welded together to ensure that the columns are held firmly into place.
Sturdier columns will typically require more time to complete, but the cost is usually less expensive than going with a less effective method. Most companies will provide a quote for a wide variety of services and will be able to provide you with options that will fit your budget.
