Inspection, repair, testing and shell replacement of fabric firefighting buckets — brand-independent, carried out in the Netherlands.

Helicopter firefighting buckets work long days under harsh conditions: dipping in rivers and lakes, abrasion on rough riverbeds, UV, foam concentrate and thousands of fill-and-dump cycles. The fabric of the bucket — the shell — is the wear part, while head, cables and valve last much longer. Tears longer than 76 mm, broken top loops or separated welds mean, according to the manufacturer's repair criteria: immediately out of service.

Buitink Technology offers European operators an alternative to long return shipments to North America: inspection, repair, testing and complete shell replacement — carried out in our workshop in Duiven (the Netherlands) by specialists in high-performance technical textiles.

Buitink has developed and manufactured flexible structures from coated technical fabrics since 1948: from inflatable structures and lifting bags to flexible reservoirs of hundreds of thousands of litres. All relevant techniques are in-house: HF and hot-air welding, heavy-fabric manufacturing, webbing and cable work, and materials testing. We are ISO 9001 certified.

All brands

We work brand-independently: Bambi Bucket® and Bambi MAX®, but also Cloudburst, FAST, Monsoon-type and other fabric buckets. We are also happy to help with older or no longer supported models.

Inspection and mechanics

We inspect the complete bucket — fabric and mechanical parts:

Fabric and seams (shell)

• Full visual inspection of shell, panels and welded seams
• Check of top loops, webbing loops and wear strips against the manufacturer's repair criteria
• Assessment of coating (wear, UV damage, pinholes) and previous repairs
• Dimensional check of critical interfaces (valve opening, batten pockets, bracket positions)

Mechanical parts

• Suspension cables: fraying, kinks, swage fittings
• Chains, shackles and M-strap attachments
• IDS hub and spokes, shell brackets, restrainer cables
• Dump valve: function, sealing, purse lines, tripline
• Electrical: solenoid, wiring and connector (function test)

Every inspection results in a report with findings per component, classified by urgency, with a fixed quotation for the repair.

Repair and shell replacement

Repair

• Permanent patch repairs: hot-air welding (preferred method) or bonding, matched to the fabric type (PVC- or PU/TPU-coated)
• Repair of welded seams, batten pockets and wear strips
• Replacement of webbing, top loops, purse lines and small hardware
• Every repair is concluded with a tensile test on a co-welded test sample

Complete shell replacement

• Fabric worn out but head, cables and valve still good? Then a new shell is the economical choice.
• We measure your bucket and manufacture a replacement shell from modern TPU-coated fabric
• Your existing valve, head and hardware are transferred and adjusted
• Considerably more economical than a complete new bucket

Testing and quality control

Every bucket leaves our workshop with a test report. Depending on the assignment we perform:

• Tensile tests on fabric samples and welds on our own test benches (2.5 up to 300 kN)
• Breaking-strength checks of webbing, loops and attachments
• Leak and function test of the dump valve and seals
• Electrical function test of solenoid and controls
• Dimensional report of the critical dimensions after repair or replacement

All results are recorded per serial number, so the maintenance history of every bucket is traceable — including for your own quality and aviation records.

How it works

• Delivery by pallet or in our transport bag; we can arrange transport within Europe.
• Priority service during the fire season can be discussed.
• Inspection and report at a fixed price; repairs only after your approval of the quotation.
