Retaining Walls Christchurch Wide

In simple terms, retaining walls are built for the purpose of holding soil behind them. Many residential and commercial real estate projects require the construction of retaining walls, for a variety of purposes outlined below:

  • When a property has a surrounding garden or lawn, building a stone retaining wall around the area helps to reinforce the boundaries on the property, hold the soil and increase the appeal of the place.
  • Construction projects on highways often require large-scale reinforced walls to retain the soil.
  • Both commercial and residential retaining walls can help to reduce and restrict erosion caused by nature such as wind and rain.
  • Retaining walls are often built around terraced yards to minimise maintenance.
  • Hillside construction projects need extra reinforcements like strong retaining walls to keep loose soil in place.

Building a retaining wall is a complicated process because there are more than ten different types of retaining walls. In order to ensure you get the most suitable retaining wall for your project, it’s important to consult with a professional to determine which retaining wall your project requires.

The retaining wall process involves a number of technical steps like land surveying, identifying soil type, establishing a natural drainage pattern etc. For the best possible outcome long-term, hire an experienced professional contractor to build your retaining walls in Christchurch.
