Frequently Asked Questions

Modernstone Retaining Wall Blocks are versatile blocks available in shades of Charcoal, Beach, and Light Sand. They are commonly used for retaining walls, raised garden beds, tiered garden areas, creating level areas on sloping properties, landscape edging, and feature walls.

Their modern design and clean finish make them a popular choice for both residential and commercial landscaping projects.

Modernstone Retaining Wall Blocks are suitable for walls up to 2 metres high. Walls over 1 metre require specific engineering and certification.

The suitable height for your project will also depend on factors such as soil conditions, drainage requirements, site conditions, and the design of the retaining wall.

Note: Always follow the manufacturer's specifications for your specific project and check with your local council regarding retaining wall requirements.

Proper preparation is essential when installing Modernstone Retaining Wall Blocks to create a stable and durable retaining wall.

The general installation process includes:

  1. Preparing and levelling the foundation area.
  2. Creating a compacted base for the first course of blocks.
  3. Installing the first row carefully to ensure it is level.
  4. Stacking additional blocks while maintaining correct alignment.
  5. Installing drainage material behind the wall where required.
  6. Backfilling and compacting behind the wall.

Note: We recommend following the manufacturer's installation instructions for the specific requirements of your project. The guide above provides a general overview of the installation process.

The number of Modernstone Retaining Wall Blocks required depends on the length and height of your retaining wall. Each block measures 440 × 280 × 165mm, providing approximately 13.8 blocks per face square metre.

To calculate the quantity required, measure the total length and height of your retaining wall to determine the wall's face area in square metres. Multiply the total face area by 13.8 blocks per square metre to estimate the number of blocks required.

For example, a wall measuring 5m long × 0.66m high has a face area of 3.3m² and would require approximately 46 blocks before allowing for wastage.

Note: We recommend allowing approximately 5–10% extra blocks for cuts, corners, breakages, installation adjustments, and future replacements.
