Why Retaining Walls are Important


Retaining walls are more than just an aesthetic addition to your landscape; they play a crucial role in maintaining the integrity and usability of your property. In Wollongong, where varying terrains are common, Bennett's Environmental designs and constructs retaining walls that provide essential benefits:


  • Soil Erosion Prevention: They effectively hold soil in place, preventing erosion caused by wind and water.
  • Flood Control: Properly constructed walls help manage water flow during heavy rains, reducing the risk of flooding.
  • Expanded Usable Space: Retaining walls can create flat areas on sloped land, increasing the usable space for gardening, patios, or other landscape features.
  • Structural Support: They provide necessary support to keep the surrounding earth stable, which is especially important for properties on uneven terrain or near water bodies.


Investing in a high-quality retaining wall not only secures your land but also enhances the overall value and functionality of your property. Trust Bennett's Environmental to deliver robust and effective retaining solutions tailored to the unique challenges of the Wollongong environment.

Frequently Asked Questions


  • What maintenance is required for retaining walls to ensure their longevity?

    Maintaining retaining walls involves regular checks for drainage issues, ensuring weep holes are not blocked and vegetation near the wall is controlled to prevent root damage. Seasonal inspections are recommended to address any potential issues early.

  • What is the typical lifespan of a galvanised water tank, and how can it be extended?

    Galvanised water tanks generally last between 10-20 years, depending on the water quality and maintenance practices. Lifespan can be extended by regular cleaning, periodic inspection for corrosion and immediate repair of minor damages to prevent worsening.

  • What factors determine the size and type of water tank suitable for my property?

    The size and type of water tank suitable for your property depend on your water usage, available space and specific water storage needs. Factors like roof catchment area and intended use of collected water (e.g., garden irrigation, household use) also play a crucial role. Our team provides personalised advice based on these factors.
