Concreters Bilpin

Yes. We build driveways and crossings, shed slabs, hardstand, retaining walls, pool surrounds and outdoor areas for properties in Bilpin and the surrounding district, including Kurrajong Heights, Kurrajong Hills, Blaxlands Ridge and Kurrajong.

Yes. We excavate, form and pour shed and cool-room slabs on orchard properties, including thickened edges and set-downs where the engineer calls for them. Tell us what will drive on it and how the building will be used, and we’ll quote the slab, base and hardstand together.

Yes. Bilpin is in the Hawkesbury local government area. Before any work starts on the crossing between the road and your boundary, the owner or contractor has to lodge Hawkesbury City Council’s Agreement Form for Driveways with the required fee. Council also requires the contractor to carry public risk insurance with a minimum cover of $20 million and to show evidence of it before starting.

Council’s driveway specification sets a minimum compressive strength of 25 MPa at 28 days in accordance with AS 3600. A residential crossing is a minimum 100 mm of concrete with a single layer of SL72 mesh; heavy duty is a minimum 150 mm with two layers. Reinforcement sits on bar chairs at a maximum of one metre spacing, about 25 mm below the finished level, and council inspects once with the formwork and steel in place, on 24 hours notice.

It depends on the length, how much excavation and base preparation the ground needs, whether an old surface comes out, the crossing at the road, and the finish. Acreage driveways vary far more than suburban ones, so the accurate number comes from seeing the site. Quotes are free.

Council’s specification is the floor: where the subgrade material is unsatisfactory it has to be removed and replaced with a minimum of 150 mm of approved sandstone or road base, and on a non-granular subgrade the slab is placed on a 25 mm layer of sand. Beyond that, a site classification under AS 2870 comes from a geotechnical soil test on your block, not from a suburb map.

Usually, and where we can’t, a pump or a staged pour does it instead. What decides it is width, the surface of the existing track, overhanging branches and how tight the turns are. We check access before quoting rather than on the morning of the pour, because a truck that can’t reach the site is a wasted load and a wasted day.

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.

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.

No. We take on complete jobs — driveways, shed slabs, hardstand, retaining walls, pool surrounds and outdoor areas — where we control the work from excavation through to finish. We don’t do small patch-up repairs.
