What Geosure (pty) Ltd does

Geosure (Pty) Ltd is a South African specialist geotechnical engineering consultancy founded in 1992 and headquartered in Durban. It delivers integrated services across six core modules: geotechnical investigations (borehole drilling, penetrometer and plate load testing, slope stability assessments), geotechnical design (settlement, bearing capacity, mechanically stabilized earth, lateral support, pile design), geohydrological/groundwater investigations (borehole drilling, contamination assessment, groundwater modelling, water use licensing), pile integrity testing, SANAS-accredited specialised geotechnical testing, and on-site laboratories. Operations are structured through four wholly-owned subsidiaries — Geosure Gauteng (Pty) Ltd, Geosure Groundwater (Pty) Ltd, Geosure Laboratory (Pty) Ltd, and Geosure Site Laboratories (Pty) Ltd — with offices in Durban (headquarters and two permanent laboratories), Johannesburg (Sandton), and Richards Bay, plus mobile on-site labs deployed at project locations.

The firm's technical stack combines specialized instrumentation for pile integrity testing — a Diagnostic Pile Analyser and Pile Echo Tester (PET) using Frequency Response and Sonic Echo methods, sonic logging/tomography with CHUM software, supported by a technology and training partnership with NDT Technology (UK) — with numerical analysis tools (Settle 3D settlement software, Phase 2D finite element analysis), groundwater numerical modelling, and a SANAS-accredited laboratory operating under ISO 17025 covering triaxial, consolidation, permeability, point load, and UCS/UCM tests to ASTM, British Standards, and ISRM methods. The company holds a Level 1 B-BBEE rating (100% previously-disadvantaged ownership, maintained 15+ years) and has won two SAICE Branch Awards for Technical Excellence in Durban.

Geosure generates revenue through project-based professional services engagements, priced per scope of investigation, testing requirements, and complexity, with no publicly disclosed standard pricing tiers. Its customer base spans infrastructure developers, government and municipal authorities (Ethekwini Municipality, Umgeni Water), engineering consultants, piling contractors, and environmental clients, with named enterprise references including Gautrain, Old Mutual, Franki, and AECI. The firm has completed projects across 16 African countries (Botswana, Mozambique, Swaziland, Tanzania, Mauritius, Angola, Malawi, Namibia) and operates a direct-to-client GTM motion from its three South African regional offices without intermediary channels.
