Spillways

EARTHLOK™ delivers reliable, high-performance erosion protection for spillways, combining flexible installation with long-term stability under extreme flow conditions.

Why EarthLok™ is used for Spillways

EARTHLOK™ is highly effective for spillway protection, offering a durable and flexible erosion control solution in areas subjected to high-velocity flows and frequent overtopping. Its interlocking concrete blocks conform to the spillway profile, providing immediate armouring while allowing water to pass through in a controlled manner. This prevents soil erosion, scouring, and structural damage during storm events or dam releases.

Suitable for auxiliary, emergency, and chute spillways, EARTHLOK™ provides a permanent, low-maintenance alternative to rock rip rap or concrete slabs. It can be installed quickly with standard construction equipment and accommodates complex geometries and transitions. For extreme flow conditions and steep grades, EARTHLOK™ systems can be customised with integrated earth anchors to enhance stability and ensure long-term performance in demanding environments.
