Sand dam road crossings

At Excellent Development we believe incorporating the principles of sand dam technology with low volume road crossing designs will deliver a more robust and cost-effective rural roads infrastructure.

Sand dam road crossings will:

Minimise costs of repair and reconstruction.
Improve reliable access to markets and services.
Reduce local flooding and erosion.
Recharge groundwater.
Supply millions of litres of safe water for multiple use.
Contribute to climate change resilience.
