Retaining Walls Hills District

About Our Retaining Walls Work in the Hills District

We have been doing retaining walls across the Hills District long enough to know which streets throw up surprises. The one that catches people out most often is clay that moves seasonally enough to matter for any retained face.

Retaining Walls in the Hills District is as much about access and set-out as it is about materials. On rolling ridge country with acreage in the north and dense estates in the west, getting the sequence right is what keeps a job to program.

Owners in the Hills District tend to call us at the point where patching has stopped working. By then the underlying issue is usually water weeping through the face because there is no drainage behind it, and a repair only postpones it.

If you want a straight answer about what your the Hills District site actually needs, call 0492 879 796 and we will come and look at it.

When Retaining Walls Needs Replacing

There is a pattern to retaining walls jobs in the Hills District, where the housing is largely everything from 1970s brick on quarter acres to brand new estate housing. A whole street tends to reach the same point at the same time.

• A wall built without allowance for the driveway sitting above it
• A wall that has begun to lean or bulge in the middle
• Timber sleepers that have rotted at the base course
• A level change that was filled rather than retained

What The Hills Shire Council Controls

Where a job needs approval we say so at quote stage rather than after the deposit. It is one of the few parts of a the Hills District project that cannot be fixed later.

We can tell you what usually applies around the Hills District, and we will always recommend confirming the current position with The Hills Shire Council before you commit. Controls change, and a wrong assumption is expensive to unwind.

The the Hills District Ground Conditions We Design For

Nothing about the Hills District is standard once you get past the front gate. We measure the whole site rather than the section you called about, because a canopy of established trees that keeps timber damp through winter has a habit of turning up mid-job otherwise.

Drainage is the quiet issue on Wianamatta shale clay grading to sandstone along the northern ridges. Water that cannot get away sits against footings and behind retained faces, and that is where most premature failures in the Hills District begin.

The practical constraint on most the Hills District jobs is long boundaries that need setting out properly before anything is ordered. We work the materials route out before quoting, because a barrow run instead of a truck changes the program substantially.

Retaining Walls Configurations We Install

What Happens After You Call

Services are located before excavation, every time. Around the Hills District the older streets carry runs that are not where the plans say they are, and a strike is expensive for everyone.

We set out the whole run first, mark the levels, and agree the approach on site before anything is ordered. Once material is cut for a the Hills District job it is committed.

• Engineered walls with certification
• Concrete sleeper walls with steel posts
• Repairs to failed and leaning walls
• Timber sleeper walls
• Agricultural drainage behind every wall
• Stepped and terraced designs
