Waste dump stabilisation systems improve the stability of overburden and waste rock dumps by reinforcing soil masses, controlling erosion, and managing surface and subsurface water. They provide safe, durable, and economical solutions for mining operations where steep dump slopes, weak foundation conditions, and long-term environmental performance are critical. TechFab Waste Dump Stabilisation Systems are engineered to deliver reliable slope stability throughout the operational and post-closure life of the mine.
Overview
Available Systems
Products
Waste dump stabilization systems are engineered geotechnical solutions designed to improve the stability and performance of mine waste dumps, overburden dumps, and waste rock stockpiles. Their performance is achieved through the integration of reinforcement, confinement, drainage, and erosion control systems to enhance both internal and surface stability.
These systems are designed using established geotechnical engineering principles and incorporate effective drainage measures to reduce pore water pressure, minimise erosion, and maintain long-term slope stability under varying environmental and loading conditions. They are widely adopted in mining projects for waste dump stabilization, overburden dump construction, dump expansion works, rehabilitation of existing dump slopes, mine closure projects, and erosion protection.
TechFab offers integrated waste dump stabilization solutions incorporating high-performance geogrids, geocells, drainage composites, erosion control systems, and geotextiles. The TechFab engineering team provides complete technical support, including slope stability assessment, reinforcement design, drainage planning, erosion control design, material optimization, and construction guidance.

Waste dump stabilisation refers to engineered geotechnical solutions that improve the stability and performance of mine waste dumps, overburden dumps, and waste rock stockpiles. It integrates reinforcement, confinement, drainage, and erosion control systems to ensure both internal and surface stability.
Mining waste dumps often face challenges such as steep slopes, weak foundations, erosion, and settlement. Stabilisation systems:
