Specialist process cleaning and industrial services company Bongela Mining & Industrial Services is redefining how operations approach maintenance, safety, and efficiency across South Africa’s platinum, gold and increasingly industrial sectors. Established in 2009, Bongela has evolved from a niche silo cleaning operation into a multi-service provider supporting critical plant infrastructure across both mining and heavy industry.
Today, the company partners with leading mining houses as well as clients in the cement and industrial processing sectors, delivering high-risk cleaning, inspection, and rehabilitation services that reduce downtime and improve operational performance. “At its core, Bongela is about solving real operational challenges on-site,” says CEO Raymond Graham.
“We saw early on that downtime in processing plants, especially around silos and material handling systems, was a major bottleneck. By developing safer, faster cleaning methods, we have been able to significantly reduce turnaround times while improving safety outcomes.”
From niche service to cross-sector solutions provider
Bongela’s origins lie in addressing one of the mining industry’s most persistent challenges: the safe and efficient cleaning of silos and processing infrastructure. Traditional methods were labour-intensive, slow, and often hazardous, exposing workers to risks such as engulfment and structural collapse.
By introducing specialised techniques and systems, Bongela reduced cleaning times from a week to as little as one to two days, while minimising risk. This ability to accelerate maintenance cycles without compromising safety has become a defining feature of the company’s value proposition.
From this foundation, Bongela has evolved into a provider of integrated process cleaning and maintenance solutions, with capabilities that extend across both dry and wet sections on mines and a wide range of processing environments.
This includes the cleaning of bunkers, transfer bins, and thickeners, where material build-up can severely impact throughput, as well as the deep cleaning of flotation cells and associated systems to support optimal recovery performance.
Hydro-mining and material recovery
The company has also developed strong capabilities in hydro-mining and material recovery, using high-pressure and ultra-high-pressure water jetting systems to reprocess accumulated material in process control dams and all wet circuits, often returning valuable resources back into production. This approach not only enhances efficiency but also aligns with more resource-conscious and sustainable operating practices.
Complementing these services is a growing focus on structural integrity and long-term asset performance. Bongela conducts detailed Structural Inspection & Maintenance Management (SIMM) inspections, provides defect reporting, and undertakes concrete rehabilitation work, including high-strength linings and specialised repair applications, helping clients extend asset life and improve maintenance planning.
Importantly, these capabilities are not limited to mining. Bongela’s expertise in confined spaces, high-risk environments and process infrastructure has enabled the company to expand into industrial, cement and petrochemical sectors, where similar operational challenges exist.
Safety and compliance at the core
Operating in high-risk environments, Bongela places safety and compliance at the centre of its offering. The company’s methods not only reduce operational downtime but also align with stringent regulatory requirements, including mandatory inspections and safety standards.
“Our approach is always safety-first,” says Graham. “We design our methods to eliminate unnecessary exposure, reduce manpower in confined spaces, and ensure that every job is executed with the highest level of control.”
In addition to cleaning and maintenance, Bongela supports clients with inspection reporting, working-at-heights safety systems, and access solutions, enabling more proactive, compliant and efficient asset management.
Diversifying for sustainable growth
Bongela’s expansion into industrial, cement and petrochemical sectors reflects a deliberate strategy to diversify its client base while applying its specialised expertise in new environments. These sectors face many of the same challenges as mining, including confined space risks, material build-up, and the need to minimise downtime, making Bongela’s solutions directly transferable.
The company has already established a footprint in the cement industry and is advancing opportunities in large-scale industrial operations, including petrochemical facilities, where safety, efficiency and reliability are critical.
“At the same time, we are investing in the future,” adds Graham. “We are exploring robotics and advanced technologies that can further enhance safety and efficiency, particularly in hazardous environments. Diversification is a natural progression for us as we look to grow the business in a sustainable and controlled way.”
Rope access technicians and process cleaning specialists
Bongela employs a highly specialised workforce, including rope access technicians and process cleaning specialists. Wherever possible, the company sources talent from local communities around its operational sites, contributing to skills development and employment.
“Our people are our greatest asset,” says Graham. “This is not a commoditised service. It requires experience, training, and trust. We invest heavily in our teams training and skill development to ensure that we deliver consistently high-quality work.”
With a strong track record, established client base, and a growing presence across both mining and industrial sectors, Bongela is positioning itself as a leading provider of specialised process cleaning and maintenance solutions in Southern Africa.
“Our vision is to grow the business sustainably,” concludes Graham. “We want to be recognised as a trusted partner across mining and industry for safe, innovative, and efficient process solutions.”
