Erosion Protection & Concrete Retaining Walls

Busck Prestressed Concrete is the sole licensed manufacturer and supplier of West Lock Concrete Solutions, an innovative three-pronged interlocking concrete block system designed to stop shoreline erosion on New Zealand’s coasts and riverbanks. Unlike rock walls, sandbanks and other temporary ocean erosion control measures, West Lock Concrete Solutions is a sustainable, lasting solution that is driving positive change in the way New Zealand preserves its coastline. Although designed specifically for ocean erosion protection, the applications of West Lock Concrete Solutions are limitless. West Lock Concrete Solutions’ interlocking concrete blocks have been used for a variety of civil engineering constructions including bridge approaches and concrete block retaining walls.

Kassel Kerb®

Busck Prestressed Concrete is the sole licensed manufacturer of the Kassel Kerb® range in New Zealand and Australia.

The design philosophy behind all Kassel Kerb® products is to improve the Public Transport experience by creating barrier free bus and tram travel for all passengers.

The special raised curb provides a smooth surface for bus and tram tyres that automatically guides them to a safe stop. The raised platform and controlled positioning of the vehicle significantly reduces the gap between a stop and a vehicle making it safer and easier for all passengers to board, including wheelchair and pram users, and passengers with limited mobility. The smooth surface provides self-steering effect, is easy on tyres and reduces long-term wear and tear, while the tactile passenger platform provides a clear boundary and helps visually impaired passengers to navigate their way safely.

Primarily the Type 1.16 kerb unit is in use in Auckland for Bus stops and stations. Please contact Busck regarding project specific curves, transitions and any other Kassel Kerb® profile you may require.
