Wigram is unusual because much of it was developed on land with a known history. Former airfield and defence land gets characterised carefully before it becomes housing, which means the ground conditions on a Wigram site are often better documented than on an older suburb.
Documented ground is an advantage on Wigram retaining walls
Where a subdivision has been through a full geotechnical assessment and the platforms were formed as engineered fill with testing, that information exists and it can be used.
We ask for it at the start. A wall designed against real site data rather than conservative assumptions is often a smaller and cheaper wall, and on new subdivisions that data usually exists somewhere.
Engineered fill and what it means for your retaining wall
Fill placed in specified layers and tested behaves predictably, which is the whole point of doing it that way. It also means a wall retaining that fill can be designed with confidence rather than caution.
The contrast with older parts of the city, where fill was often placed without engineering, is stark, and it is one of the main reasons newer suburbs have far less retaining wall trouble than the Port Hills.
What we build for retaining walls in Wigram Skies
Mostly boundary walls in concrete sleeper or timber, low landscape walls and driveway edges. Heights are modest because the land is flat and the platforms were formed to sensible levels.
Which makes finish and neatness the differentiator rather than engineering. On a new build the wall is part of the first impression of the house.

Retaining walls in Wigram: common questions
Is the ground in Wigram well documented?
Often yes, because the subdivisions went through full geotechnical assessment. We ask for that data because it can make the wall smaller and cheaper.
What is engineered fill?
Fill placed in specified layers and tested, so it behaves predictably. It is why newer suburbs have far less retaining trouble than older ones.
Is there existing ground information for Wigram sites?
Often yes, because the subdivisions went through full geotechnical assessment and the platforms were formed as engineered fill with testing. We ask for it, because a wall designed against real site data rather than conservative assumptions is frequently a smaller and cheaper wall.
Why do newer suburbs have fewer retaining wall problems?
Engineered fill. Material placed in specified layers and tested behaves predictably, which is the whole point of doing it that way. Older parts of the city, where fill was often placed without engineering, are where the failures concentrate.
