The Rocklok® segmental concrete block retaining wall system has been proudly developed in New Zealand in conjunction with engineers to meet the demands found in this highly active seismic region.

Rocklok provides superior strength and performance, with a stronger pin-block connection and trench system, allowing a positive connection between the geogrid and steel reinforcement. This system also allows near vertical walls to be constructed and for high load environments.

This fully engineered system is ideal for bridge abutments, wing walls and large retaining walls. The positive connection system provides extra performance and safety when critical loads are present while still providing an aesthetically attractive finish.

The Rocklok system is designed to work in conjunction with the StrataGrid® high performance PET geogrids. Together Rocklok and StrataGrid products provide a positive connection using the unique locking trench and bar system. The Rocklok is also designed in conjunction with Cirtex® steel ladder systems for applications where inextensible reinforcement is required such as bridge abutment applications and similar.

Important information

• Please consult with your local council for site requirements and regulations before the construction of your wall.
• For retaining walls exceeding 900mm, or supporting additional loads, slopes, etc., engineering advice should be sought.
