An introduction to choosing the right wall

When septic system designed and installed for building a retaining wall, there are a variety of factors to consider, regardless of whether it’s intended for residential or commercial use. The same standard of care should be applied to walls as a bridge since they are both structures. Depending on the application and our experience, we may wonder what style of wall will work best for the site, how deep the footing needs to be buried, if it needs reinforced, or even what material is best for the location.

The purpose of all residential retaining walls designed and installed is to hold soil behind them. However, the specific needs will vary depending on the project. Walls can range from small landscape stone walls to surround a garden to enormous soil-retaining projects along a highway. Below we look at four of them.

ü Location: When choosing a location for our wall, make sure you have a detailed understanding of property lines and both above ground and underground utilities including stormwater management systems and irrigation.

ü Soil: The soil that creates the foundation, or base, needs to be examined to ensure it meets the strength required to support the wall. We should determine the type, bearing capacity (the capacity of soil to support a load), stress parameters, and friction angle (resistance to movement) of the soil used for the foundation and reinforced zone along with the retained soil zone.

ü Design: To begin the design, we must calculate the corresponding wall heights, footprint sizes, slopes, and the setback angle which are dependent on the site elevation and grade.
