Engineering for the process industries
HAW engineers, builds, protects and erects plant for the chemical, power, fertilizer, rail, water, mining, hydrogen, petrochemical, oil & gas and pharmaceutical industries. From Bockenem, Germany, as part of the Jasmino Group.
Where we work
Every industry below draws on the same engineering and manufacturing, EPC and site services, and surface protection. Tell us the process, the duty and the deadline, and we will tell you what we would build and how we would deliver it.

Rail & Tank Wagons
Bockenem is Europe's largest rail-connected centre for lining tank wagons. Wagons arrive on our own siding, are blasted, lined, vulcanised and tested in the workshop, and leave by rail. We also carry out main inspections and special tests on rail tank wagons and road tankers.
- Rail-Connected Workshop
- Wagons come straight into the Bockenem workshop by rail, with no road transport
- Surface Protection
- Interior blasting, rubber lining and vulcanisation in our autoclave
- Inspection & Testing
- Main inspections and special tests on rail tank wagons and road tankers
- Testing & Return
- Spark testing, thickness checks and documentation before the wagon returns to service
Water Treatment & Desalination
Filter vessels, clarifiers, tanks and piping for effluent treatment, sewage treatment and desalination plants. Linings chosen for the water chemistry, from brine to treated effluent.
- Equipment Manufacturing
- Filter vessels, clarifiers, aeration tanks and piping
- Onsite Erection & Commissioning
- Installation, commissioning support and maintenance
- Surface Protection
- Epoxy, vinyl ester and rubber linings for water and brine
- Repair & Re-lining
- On-site repair and re-lining of filters and tanks in service
Mining & Metals
Leach tanks, digestion and settling tanks, autoclaves, electrolysis cells and slurry piping for ore processing, and pickling lines, electroplating tanks and regeneration plants for metal processing. Abrasion-resistant and acid-resistant linings for both.
- Equipment Manufacturing
- Leach tanks, autoclaves, thickeners and slurry piping
