CIVIL

PTC Civil specialises in multiple shoring and stabilisation works, namely piling, ground anchoring, shotcreting and slope stabilisation. We provide highly experienced, dedicated engineering and labour professionals focussing on efficiency, productivity, and delivering a high standard of service.

We are leaders in providing cost effective and innovative solutions. Over time, PTC Civil has built a portfolio of successfully completed high quality works, on time and under budget. At PTC Civil, we assure attention to detail to all of our clients irrespective of the size of the project or scope of works, and always produce the results that our clients desire.

Shotcrete

The PTC Civil Shotcrete team are reliable and committed to a quality finish. Our hand-picked team is comprised of experienced concrete pump operators to ensure the quality of service is always in accordance to our strict standard and in compliance with our OH&S AS4801.

Our team of renderers offer a wide range of concrete surface finishes and colours required by our clients.

Surface finish types;

• Float Finish
• Steel Trowel Finish
• Gun Finish

Anchoring

The PTC Group’s expansion lead us into investing in cutting edge machinery and technology to provide the best in anchoring systems.

Temporary and Permanent Strand Anchoring: This system works in the same way as a typical post tensioned member. The anchors transfer forces into the ground and provide stability for the shoring wall through the prestressed tendons. The designed Anchor can vary in length depending on ground conditions and loads. The strands are de-stressed when temporary anchoring is required.

Soil Nails: Soil Nails increase the load bearing capacity of a soil through a passive anchoring mechanism and are suitable for slope or embankment stabilisation and construction pit walls. They are installed in a pattern and grouted to obtain a stable soil section.

Rock Bolts: Rock Bolts are used to stabilise unstable rock cuts and inside tunnels. They provide a compressive force to support to an unstable rock exterior.

Drill Hollow Bar System: This anchoring system works as a load bearing Soil Nail with the combined mechanism of a micropile. It is an effective method for slope stabilisation and basic excavations. Drilling and grouting can be achieved in a single procedure therefore installation is efficient and available for a variety of soil types.

Piling

CFA Piling: Continuous Flight Auger Piling works by drilling to the design level, and in that same continuous sequence of operation, concrete is pumped through the stem of the auger as it is removed. Finally a reinforcement cage is inserted into the liquid concrete. This technology is efficient and also suitable for installation below the ground water table.

Sheet Piling: Sheet Piles are thin steel sheets which are embedded in sequence, interlocking to construct a retaining structure that transfers back fill pressure into the foundation below. Soil conditions determine whether they are driven or vibrated into the ground.

Bored piles: Bored Piles are essential in building foundation works where it is necessary to manage large vertical loads and bending moments. They are constructed by drilling, inserting a temporary casing, installing a reinforcement cage and then placing concrete.

Capping beams: Capping beams function to transfer vertical loads into constructed piles, in addition functioning as pile caps, therefore inhibiting pile lateral displacement.
Steel Fixing – supply and install of steel reinforcement
Shoring wall reinforcement such as Mesh, Dowel Bars, Horizontal Bars and Vertical bars are installed in conjunction with shotcrete to provide additional retaining force. Strip Drains are also secured in order to release sub soil water.
