REpairing Retaining Walls, Arches, Bridges and Homes| North and South Islands | New Zealand

Our REpair department serves to rectify common issues with ageing bridge & retaining wall structures, bridge expansion joints and deck seals, buried arches, culverts and pipes. And as the worlds’ infrastructure ages, there is an integral need for a company that can deal with the complexities surrounding remedial works on retaining structures, bridges, tunnels & water services on all scales, large or small.

REpair of ageing civil and residential structures is something that separates us from other contractors.

The difference between the traditional geo-contractor and the operational capacity of retained earth is that we operate in both small-scale residential and large scale commercial. We are content in bringing superior levels of service across the board.

A bridge is just as important as your home. Therefore, we apply the same level of expertise across all projects — regardless of the size of the job or contract value.

We remedy critical failures such as overturning or sliding, rupture, cyclic fatigue, mechanical disturbance, water-ingress issues such as concrete cancer & scour (soil loss through weather/ water), subsidence, concrete panel structural or connection-point failure, general cleaning and maintenance including anti-graffiti treatments, acid sulfate reactivity, sealing and general surface treatments.

REpair of civil structures is of utmost importance. retained earth have the know-how to complete technical remediation of existing structures.

retained earth are qualified to also carry out underpinning and rectification of structural defects through methods of remediation & prevention; extending intended design life and reinstating structural integrity to existing bridge abutments & components, grade separations, arches, culverts, and other systems of retention and slope stabilisation.

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.

soil stabilisation

retained earth also provides in-depth construction management, guided by years of practical experience in Geotechnical Construction. 

retained earth offer many techniques and proprietory products for structural remediation and protection from seismic activity and subsidence.

For all of your soil, foundation and embankment stabilisation requirements, contact retained earth for further information.

Global Stability : The Retained Earth Philosophy | Systems Development

When speaking in a Geotechnical Engineering sense, “global stability” relates to the overall stability of a structure. This extends outside the typical design considerations such as structural adequacy or “internal stability” and relates to preexisting site conditions such as seismicity or acceleration and general soil types and how they affect the internal design.

Retained Earth, as a business philosophy, have adapted this engineering consideration into our general business methodology and approach. We endeavour to encompass all components of seismic effects on buildings and general soil structures.

This is reflected in our approach in creating various cutting-edge systems in the retaining of soil and the buildings that are supported above and also the protection of the structure itself as it experiences the cycles of expansion encountered through thermal and seismic movement.
