Geopractica undertakes foundation investigations through the profiling and sampling of subsoils by descending deep large diameter auger holes.  Geopractica employs engineering geologists for fieldwork using in house equipment supplied by Geopractica Contracting.  Safety in large diameter trial holes is of paramount importance and the engineering geologist is equipped with precautionary safety harness and breathing equipment. Borehole core logging from core drilling, done in house by Geopractica Contracting, is used for site investigations for buildings, bridges, mine developments, dams, roads and railways.    

Geopractica makes extensive use of Tractor mounted TLB excavators, owned by the company, for excavating test pits to depths of 3m to 4m for the purposes of profiling and sampling subsoils for site investigation for - Foundation Investigation, Road Centre Line investigation and Borrow Pit Location.

  Geopractica provides geotechnical consulting services throughout the engineering industry for Mine infrastructure development, Oil and Gas related developments, Commercial developments, Rail, Roads and Earthworks, Dams, Bridges and Harbour developments.  Using in house facilities Geopractica provides it's clients a full range of geotechnical services from the planning stage to drilling and probing to field data acquisition to laboratory testing and final report preparation and presentation.

Geopractica used magnetic survey together with core drilling to delineate the Ogies Dolerite dyke at the new Tweefontein Coal development for Xstrata.

LATERAL SUPPORT, GROUTING, CORE DRILLING, WORKSHOP   Geopractica Contracting has completed many piling contracts in saturated soils requiring the use of temporary casings. Geopractica Contracting installs CFA piles for the new Foschini Head Office in Cape Town. Pile integrity testing using the Cross Hole Sonic logging technique.   Geopractica Contracting installs a piled anchored retaining wall for the Voorspoed Diamond Mine Primary Crusher pit. Geopractica Contracting successfully completed the access ramp for an entrance to the Benmore Shopping Centre underground parking garage by progressively excavating, soil nailing and shotcreting the vertical faces.     Rock wall stabilization to provide lateral support for the Ennerdale Pump Station south of Johannesburg. Shotcrete application of a sloping face for erosion protection of Voorspoed Primary Crusher wing walls.   Geopractica Contracting has completed many grouting contracts for the infill of dolomite cavities, curtain grouting and injection grouting.   Centre line of Kayelakera dam in Malawi, ready for drilling and curtain cut off grouting.  Geopractica was required to undertake core drilling, Lugeon water acceptance testing followed by stage grout injection to depths of 30m below the dam foundation level.     Click on the pdf icon to the left, to download our Site Investigation printable brochure. [column size=half position=first ] Geopractica Contracting runs a fleet of 10 core drilling rigs capable of geotechnical core drilling to depths of 100m. Geopractica Contracting moves a drill rig onto a scaffold platform erected over water for the investigation for a bridge widening on the N14 outside Delareyville.    Geopractica Contracting core drilling for site investigation for onshore gas refinery in Northern Mozambique. Geotechnical core drilling from a jack up barge in Durban Harbour for the site investigation for extensions to the new container terminal. Core drilling off Geopractica Contracting's floating platform.    

Geopractica Contracting has in house engineering facilities and is able to design and engineer most parts needed to service its fleet of equipment. Maintenance and repair of Geopractica Contracting's 40 ton piling rigs is done in house at the Diepsloot yard.   Geopractica Contracting employs qualified mechanics and runs a fully equipped workshop from its Diepsloot yard to repair vehicles and equipment. Geopractica Contracting's 500 m2 covered workshop space, eqquipped and manned to handle all manner of mechanical breakdowns and maintenance requirements.
