Decontamination of Mechanical Equipment at a Construction Materials Factory (Factory Flooding, Decontamination, and Rust Prevention)

A construction materials manufacturing factory located in Okayama Prefecture suffered submersion damage due to an overflow of local waterways caused by torrential rain. This case study highlights how RecoveryPro successfully achieved a massive reduction in downtime for factory restoration and business continuity by performing on-site precision disassembly cleaning, specialized decontamination, and rust prevention mapping on custom-made production machinery.

1.Overview

  • Location: Building materials manufacturing plant
  • Equipment Affected:Six custom bending machines , Control panels ,Pits ,Other production equipment
  • Type of Damage: Flood damage (approx. 50 cm inundation due to heavy rain and waterway overflow)

2. Project Timeline

  • Inspection & Quotation: 4 days after the disaster
  • Work Duration: Total of 10 days(Full recovery completed approximately 2 weeks after the incident)

3. Details

RecoveryPro mobilized to the site four days after the flood, conducting damage assessment and preparing a quotation.
A rapid recovery plan was proposed to perform all restoration work—from the building to the equipment—on-site, and decontamination work began immediately.

  1. ① Pit Drainage and Initial Response
    A thorough drainage operation was carried out to remove the large volume of muddy water accumulated in the pits beneath the machinery and on the floors, ensuring a safe and workable environment.
  2. Precision Disassembly, Cleaning, and Decontamination of Machinery
    The submerged bending machines and surrounding equipment were carefully disassembled into individual components and thoroughly cleaned to remove mud and sludge.
    Early-stage microscopic corrosion (rust) was eliminated using proprietary technologies (decontamination process).

③Cleaning of Precision and Electrical Equipment

  • Complete Drying and Anti-Corrosion Treatment of Electrical Components:
    Highly sensitive electrical systems, such as control panels, were disassembled and cleaned.
    This was followed by a complete drying process to fully remove all moisture, and specialized anti-corrosion and restoration treatments were applied.

④Final Adjustment with Manufacturer Support

  • After completing restoration work, final operational checks and precise adjustments were carried out in cooperation with the equipment manufacturer, enabling safe resumption of factory operations.

4. Strengths of RecoveryPro

nitially, the equipment manufacturer informed the client that, due to congestion caused by widespread disaster impacts, it would take three months just to conduct an inspection visit, leaving the client in a difficult situation.
Had they waited for the manufacturer’s response, the factory would likely have faced months of downtime and significant business interruption losses.
However, by performing rapid on-site disassembly, decontamination, and anti-corrosion treatments, RecoveryPro achieved a complete restoration in just 10 working days (approximately two weeks after the disaster)—an exceptionally short timeframe.
As a result, delivery delays to customers were minimized, and the client expressed a high level of satisfaction.
