Frequently Asked Questions


  • What are the signs that indicate the need for upgrading or replacing a concrete product?

    Indicators that a concrete product needs upgrading or replacement include visible cracks that compromise structural integrity, signs of wear such as pitting or scaling and efficiency issues like improper drainage in concrete channels or basins.

  • What should I consider when choosing the placement of a water tank on my property?

    Considerations should include proximity to roof downspouts for rainwater collection, ease of access for maintenance, the stability of the ground to support the tank's weight and exposure to environmental elements that could influence wear and durability, such as direct sunlight or tree cover.

  • Can retaining walls be environmentally beneficial?

    Yes, retaining walls can have environmental benefits by preventing soil erosion, managing stormwater runoff and creating terracing, which can reduce the environmental impact of landscaping by minimising the need for extensive grading and vegetation removal.
