Sand Ground Engineering is a privately owned Australian company providing specialist excavation in sand. We provide many services including:

Bulk Excavation

Sand Ground Engineering provides bulk excavation services using the latest equipment and experienced engineers. We offer bulk excavation for commercial site preparation. Bulk excavations can be quoted as per cubic metre (pm3), per tonne (p/tone), or as a fixed price rate. We offer both sand excavation and shoring and rock excavation services. • All size […]

Detailed Excavation

The precise nature of detailed excavation, such as drainage and footings excavations, calls for our smaller sized excavators. From 680mm wide, they allow access to limited areas and are perfect for the smaller, more detailed scale of works. When your project requires skill and precision in tight or delicate areas, we have the expertise and […]

CFA Piling

The Continuous Flight Auger / CFA pile is a non-displacement pile used where fast, vibration free installation is required in difficult ground conditions. The drilling process is suitable for penetrating dense layers and is unaffected by ground water or collapsing soil conditions. The pile is formed by first drilling into the ground with a hollow-stemmed […]

Diamond Rock Sawing

The new diamond tipped rock saws cut through rock at a greater rate with less force required by the excavator. The diamond saws are a lot safer than conventional methods, with the dust free cover enclosing the blade whilst cutting. We have diamond rock saws available for excavators 1 – 14t. They are suited for […]

Bored Piling

Large diameter bored piles are non displacement piles which are commonly used where large vertical loads or bending moments must be carried by a single unit. Bored piles founded in rock provide an effective means of minimising foundation settlements and a small number of high capacity bored piles can often provide significant savings in pile […]

Sheet Piling

Sheet piling is a form of driven piling using thin interlocking sheets of steel to obtain a continuous barrier in the ground. Sheet piling is commonly used to retain boundary walls during construction in situations where the adjacent buildings are intolerant to the vibration that will occur during the installation process. Normally, vibrating hammer, t-crane […]

Secant Piling

Secant pile walls are formed by constructing intersecting reinforced concrete piles. The secant piles are reinforced with either steel rebar or with steel beams and are constructed by either drilling under mud or augering. Primary piles are installed first with secondary piles constructed in between primary piles once the latter gain sufficient strength. Pile overlap […]

CSM Piling

Cutter Soil Mix (CSM) technology is the latest generation of soil mixing techniques which injects and mixes binding agents (generally cement) with the aid of water and air with in-situ soils to produce a final hardened product. Once cured, these mixed soils are capable of retaining soils and water for deep excavations, environmental cut-off walls […]

Ground Anchors

Ground Anchors are used a variety of applications for both vertical and lateral restraint. Ground Anchors (distinct from Rock Anchors) are anchors where the load-carrying bond length of the anchor is installed into soil or soft rock and in which anchor bond stresses are significantly lower that those applicable to hard rock. Sand Ground Engineering […]

Rock Anchors

Earth or rock anchors generally consist of steel elements (bars or strands) grouted in a drilled hole. The bars or strands are subsequently tensioned. This provides lateral or vertical force to resist movement of a retaining structure. Anchors are often used for excavation support, or as a part of permanent retaining walls, or to resist […]


Construction dewatering, unwatering, or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson or mine shaft by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. […]
