Castle Hill and Glenhaven
Suburban Castle Hill on one side of the Old Northern Road, large Glenhaven blocks on the ridge beside it.
From market gardens to suburbs
Castle Hill is about 34 km north-west of the Sydney CBD, at about 142 m, on Old Northern Road and Showground Road. It was once market gardens and orchards and is now mostly low-to-medium-density housing. Glenhaven, on the Great North Road route, has large homes on large blocks, with a ridge at 180 to 200 m.

Which council is your street in?
Castle Hill is split between The Hills Shire and Hornsby Shire, while Glenhaven is in The Hills. The council that owns your road sets the rules for the driveway crossing. In the Hornsby part, council says crossings may only be built by contractors it has authorised. We check before we quote.
Driveways on a tight suburban block
On smaller blocks the driveway is the front garden. We keep finishes, joints and edges tidy, and plan the break-out so you still have access to the garage for as much of the job as possible.

What we build here
Driveways and the crossing at the road, carport, garage and granny flat slabs, patios and alfresco areas, pool surrounds, paths and stairs, and decorative finishes.
Excavation included
We do our own cut, fill and base, so one crew handles the job from breaking out the old driveway to the final finish, and one price covers it.
Complete jobs, not patch-ups
Whole driveways, whole patios, whole pool surrounds — where we control preparation, pour and finish rather than patching someone else’s work.
What’s under a Castle Hill driveway?
Castle Hill is established Hills District housing on Cumberland Plain shale country, where what sits under an old driveway is usually the reason the new one needs more work than expected.
What the base has to do
The base under a slab is what the finished job stands or falls on, and on established blocks it is usually where the surprises are: old fill, a previous driveway’s broken-up sub-base, or tree roots that have lifted what was there. Council’s specification sets the minimum for the crossing at the road; past your boundary it is a design question, not a compliance one.
Assessed on site when we quote, not assumed from the street.
Reactive ground moves
Reactive clay swells when it takes up moisture and shrinks as it dries. AS 2870, the Australian Standard for residential slabs and footings, classifies sites by how much that movement is expected: Class A and S are stable to slightly reactive, M moderately, H1 and H2 highly, and E extremely. The more reactive the ground, the more the slab design has to allow for it.

What that means for your block
A site classification under AS 2870 comes from a geotechnical soil test on your property, not from a suburb map, and no honest quote assigns one without it. What we can do is look at the ground when we quote, and tell you where the preparation is going to matter.
Every block is different. A classification for your property comes from a soil test.
Which council is your Castle Hill block in?
The Hills Shire and Hornsby Shire both name this suburb in their locality lists. It changes the application, the crossing, and who is allowed to build it.
Both lists name it
The NSW Electoral Commission lists Castle Hill among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in Hornsby Shire. Your rates notice, or a section 10.7 planning certificate, names the council that assesses your block.

Under The Hills
A Vehicular Crossing Request lodged online, paid before residential work commences. The applicant supplies the contractor’s details and a copy of their public liability policy, to a $10 million minimum, and council requires them to be appropriately skilled and experienced. Two inspections — one before any concrete is poured, one at completion — on 24 hours notice.

Under Hornsby
No work may start without written permission, and levels are normally issued within five working days. A vehicular crossing in Hornsby Shire may only be constructed by one of council’s approved Authorised Contractors, carrying public liability insurance of at least $20 million held for six months. Standard residential is 125 mm with one layer of SL62 mesh, at 25 MPa, with a maximum gradient of 1 in 4. Three inspections, 48 hours notice on the formwork.

Driveway approvals in Castle Hill
A new driveway almost always includes the crossing between the road and your boundary. In Castle Hill, the first question is not how it gets built — it is which council assesses it.
First, find out whose it is
The NSW Electoral Commission lists this suburb among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in Hornsby Shire. Your rates notice or section 10.7 planning certificate settles it for your block.

Local FAQs
Anything else, call 0468 491 882.
Do you do concreting in Castle Hill?
Yes. We build driveways and crossings, carport, garage and granny flat slabs, patios, pool surrounds, paths, stairs and decorative concrete for homes in Castle Hill and nearby suburbs, including Baulkham Hills, Glenhaven, Cherrybrook and West Pennant Hills.
Can I still use my garage while you replace the driveway in Castle Hill?
For most of the job, no, but we keep that time short. We break out and pour as quickly as the curing allows and tell you in advance which days the driveway will be out of use.
Do you also cover Glenhaven?
Yes. We treat Glenhaven as part of the Castle Hill area and work across both with the same crew, the same site preparation and the same free on-site quote.
Do I need council approval for a driveway crossing in Castle Hill?
Yes — and the first question is which council. The NSW Electoral Commission lists Castle Hill among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in Hornsby Shire, so the boundary runs through the suburb. Your rates notice or your section 10.7 planning certificate names the council that assesses your block.
What are the two specifications?
Under The Hills: A Vehicular Crossing Request lodged online with payment before residential work commences, the contractor’s details and a copy of their public liability policy to a $10 million minimum, and two inspections — one before any concrete is poured and one at completion — on 24 hours notice. Under Hornsby: Written permission before any work, levels normally issued within five working days, and a crossing built only by one of council’s approved Authorised Contractors carrying at least $20 million public liability held for six months. Standard residential is 125 mm with one layer of SL62 mesh at a minimum 25 MPa, width 3.5 to 4.5 metres at the kerbline, maximum gradient 1 in 4, and three inspections with 48 hours notice on the formwork.
Why does it matter which one I am in?
Because Hornsby restricts who is allowed to build the crossing at all — only its approved Authorised Contractors — and The Hills does not. Hornsby also wants a thicker crossing, a higher insurance threshold held for longer, and an extra inspection. Same street in places, different job.
How much does a concrete driveway cost in Castle Hill?
It depends on the size, how much excavation and base preparation the ground needs, whether an old driveway comes out, the crossing at the road, and the finish you choose. On an established block, what is under the old surface is usually the variable. The accurate number comes from seeing the site, and quotes are free.
What kind of ground is a Castle Hill driveway built on?
The Hills District sits on the Wianamatta Group shales of the Cumberland Plain, and reactive clay swells and shrinks with moisture, so base preparation and reinforcement matter more than they would on stable ground. Your block’s actual site classification under AS 2870 comes from a geotechnical soil test, not from a suburb map. On an established block the bigger unknown is usually what is under the old driveway — fill, a broken-up sub-base, or tree roots.
Which council covers Castle Hill?
Mostly The Hills Shire, but not entirely. The NSW Electoral Commission lists Castle Hill among the localities included wholly or partly in The Hills Shire, and also among those included wholly or partly in Hornsby Shire — the boundary clips the eastern side. It matters, because Hornsby permits only its approved Authorised Contractors to build a vehicular crossing and The Hills does not.
Are you licensed and insured?
Yes. Southo Concrete holds NSW contractor licence 398552C and a general construction induction white card, and carries $20 million public and product liability cover plus workers insurance. Certificates of currency are available on request, along with SWMS where a site needs them, and we can complete site inductions as required.
How long will the concrete last, and will it crack?
We use high-quality materials and proven construction methods to help ensure our work lasts for 25 years or more. We also use appropriate materials and techniques to control cracking in our slabs, helping to keep it very limited, if not eliminate it altogether. Please note that cracking can be affected by factors outside our control, including ground movement, weather and site conditions.
Do you do small concrete repairs in Castle Hill?
No. We take on complete jobs — driveways, carport and garage slabs, patios, pool surrounds and paths — where we control the work from preparation through to finish. We don’t do small patch-up repairs.
