Project Description
EngeoLabCC conducted a comprehensive geotechnical investigation for the proposed replacement area of the decommissioned North Plant at Tubatse Alloys, located near Burgersfort, South Africa. The project focused on assessing soil stability and foundation conditions for the construction of a crushing and screening plant, conveyors, daybins, a master control centre, a furnace, a water tower, and coolers.
The investigation involved a detailed site assessment, including a walk-over survey, a borehole census, and the excavation of 10 test pits using a 65KW tractor-loader-backhoe. In situ tests, including dynamic penetration tests (DPSH) and a single Marchetti Dilatometer test (DMT), were conducted to gather data on soil consistency and bearing capacity. Soil samples were collected and analysed by SGS Matrolab in Pretoria for precise classification and structural assessments.

The project assessed soil stability and foundation conditions for the construction of a crushing and screening plant, daybins, conveyors, a master control centre, furnace, water tower, and coolers.
No groundwater seepage was recorded during the investigation, with borehole tests indicating static water levels between 18m and 24m below ground level. The recommended foundation strategy involved the use of competent bedrock to support heavy structures while lighter structures could be safely founded in the cover soils with proper compaction.
The investigation concluded with detailed recommendations for site preparation, including the compaction of disturbed soil layers to at least 93% Modified AASTHO density, and further testing of the contact zone above bedrock using shallow diamond core drilling to ensure settlement risks were mitigated. This project ensured a thorough understanding of the subsurface conditions, contributing to the safe and efficient development of the Tubatse Alloys facility.
