SEGMENTAL BLOCK RETAINING SYSTEM

The Allan Block success began three decades ago with the introduction of their patented segmental retaining wall product – the original Allan Block.

 

The success story continues with the development of creative and innovative construction products, aiming to revolutionise the way the world builds.

PATTERNED RETAINING WALL SYSTEM

Give your landscape a dramatic effect with patterned walls. Add a whole new dimension to your landscape! Blend the different sized blocks together into your wall and capture the look of hand-laid stone. Patterned walls resemble hand-laid stone walls,

and will require a certain level of detail and craftsmanship to construct. Some custome fitting of blocks will be required. Plan on taking a little extra time to build, particularly when building one for the first time.

Engineering advice should be sought for walls exceeding 900mm, or for retaining
walls supporting an additional load, eg. driveways, buildings or slopes etc.

With the combination these four blocks create
stunning patterned retaining walls that resemble
the aesthetic beauty of hand laid stone.

ROCKLOK

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.
