The Advantages of the retained earth CellWall™ Gravity Retaining Wall System

The retained earth CellWall™ system is a mass-gravity type retaining wall array that is comprised of cast reinforced concrete units, formed to specific size and dimension, which are then combined by utilising our proprietary construction methods.

By controlling design, manufacturing and installation, retained earth focus the ‘bulk density’ approach to the retaining and stabilisation of slopes and embankments. Our system, in its unique composition, performs specifically for high deflection situations as required for sea walls, rail bridges and road-side retaining structures such as bridge abutments and grade separations.

The CellWall™ system is perfect for sites with soft soils, rock foundations and sites with limited access.

Walls such as crib walls and gabions (see pictures below), which also are designed and constructed utilising the mass-gravity method, perform very well in their functions but still allow scour to occur. The retained earth CellWall™ system, eliminates the risk of scour by adding density to our design block.

This simple solution reduces voids in the block and therefore is also very effective at controlling the establishment of vegetation in the face of the wall structure. This, when it occurs on similar mass-gravity structures, can cause further costs for private and public assets.

With no large root masses invading the wall structure, the CellWall™ system will outperform alternative gravity wall systems.

Fix Faulty Expansion Joints | New Zealand | Joint Systems Expansion Joints

As a custom solution provider, joint system the expansion joint division of retained earth, through years of product development and project experience, can deliver retrofit expansion joint products for the repair and replacement of defective joint seals and sometimes as a result, dangerous situations for your patrons and employees.

Through cyclic fatigue, it is inevitable that the seals positioned in walls and floors will deteriorate, albeit, some quicker than others.

Have a wall that is leaning forward? Repair Your Retaining Wall

Modes of failure vary when looking at repairing a retaining wall. Depending on the type of retaining wall, the approach to repair is best decided by either an experinced geotechnical engineer or an experienced retaining wall specialist.

The beginning of failure. This retaining wall, although small, is not capable of retaining the soil behind. This is made worse by having to also hold up the fence above.

As most retaining walls in Auckland are made from timber, they are typically a cantilever system which utilises vertically-placed posts or sleepers to hold the retained embankment. There are mainly three types of failure with timber sleeper retaining walls; rotation, corrosion (rot and termite damage) and tree roots.

Rotation, in this case due to tree roots, also affects concrete block retaining walls.

Following is a before and after repair job that we carried out. The original retainer, although built with treated pine, was termite ridden and rotten from moisture/ dampness. This was removed and replaced with a smooth, off form grey concrete sleeper wall which uses galvanised steel beams.

The replacement retained earth sleeper wall also featured our heavy duty fence brackets to allow for rapid fence installation.

Want to maximise your usable land? Try a retained earth retaining wall

When working with an earthmoving company, you may hear the terminology “cut & fill”. This basically means as it sounds; some areas of work are to be excavated which is indicated by the word ‘cut’ and other areas that are to be filled, and well, you know the rest.

By doing this in a certain way, you can maximize the amount of usable, and more possibly, load bearing land in which an extension or another structure can be built on to increase the overall value of your block. This is even more critical for older blocks that have matured but nonetheless it is also a widely occurring function when building on a new block.

Concrete retaining walls by retained earth help to provide a long lasting and aesthetically appealing option when considering the various types of retaining systems on the market. Our systems utilise both cantilever anchorage and gravity itself as a means to secure an area of fill. In saying this, we also have cut zone ready retaining systems.
