A geosynthetic systems business with engineering depth.
Kontain provides lining supply, application-specific material specifications, liner optimisation and design input. Our Kontainer™ Geobags service connects civil specifications, drawings, layout and stack planning with supply. The business also develops custom-manufactured and standard geosynthetic systems for Australian and international projects. Commercial geotechnical investigations are offered separately across Adelaide and South Australia.
Why Kontain exists
Make technical geosynthetic supply clearer and more efficient.
Kontain was founded by Ben Lewis, MIEAust CPEng NER APEC Engineer IntPE(Aus), a Chartered Professional Engineer in Geotechnical Engineering with more than 14 years across geotechnical engineering, geosynthetics, technical sales and business development in Australian mining, civil, water and waste markets.
The core model is straightforward: develop systems around actual project conditions, work with capable manufacturing partners, coordinate technical documentation and deliver efficiently without carrying overhead that does not improve the outcome.
For Kontainer™ Geobags, the agreed civil specification, drawings, pad and drainage layout, bag sizing and stack planning are included when Kontain supplies the geobags, liner and associated materials. That technical input is intended to reduce avoidable risk; it is not a guarantee of dewatering performance, which remains dependent on feed conditions, conditioning, pumping and operator control.
Geotechnical investigations are a separate South Australian service. They are independently scoped around the proposed development, field evidence and reporting requirements. Where ground improvement or reinforcement is genuinely justified, that background can support a more informed solution—but it does not make product supply the default answer.
Australia remains our home market. International clients can engage Kontain for product supply, custom development, specifications, design support and testing coordination, working with their appointed engineers and local project team. Explore global project support →
Engineering credentials
A qualified engineer behind the technical advice.
Ben Lewis
MIEAust CPEng NER APEC Engineer IntPE(Aus)
Founder and geotechnical engineer. Australian professional credentials and international register recognition support Kontain’s work with owners, contractors and consulting engineers.
Chartered Professional Engineer
Engineers Australia’s assessment of competence for independent engineering practice. Ben’s Chartered area of practice is Geotechnical Engineering.
National Engineering Register
Registration in Geotechnical Engineering on Engineers Australia’s public register of engineering professionals who meet its competency requirements.
Asia-Pacific engineering recognition
Registration recognising substantial equivalence of professional engineering competence under the APEC Engineer framework, supporting mobility between participating economies.
International Professional Engineer
Australian registration under the International Professional Engineers Agreement (IPEA), supporting recognition of professional competence across participating jurisdictions.
What this means for your project
Technical advice comes from an engineer whose competence has been professionally assessed, with ongoing ethical and professional development obligations. Our work connects material requirements, test evidence, design assumptions and construction interfaces within an agreed scope.
These are Ben’s individual professional credentials. Engineering services, design certification and statutory approvals remain subject to the project scope and the registration requirements of the relevant Australian state, territory or overseas jurisdiction. International register recognition does not automatically grant a local licence to practise.
