Waterproofing & Leak Prevention

Protect Your Building from Water Damage

Factories and warehouses without exception develop roof and wall leaks
after 10+ years. Causes hide throughout the building — rusted roofing, worn hook bolts,
gaps around skylights and vents, cracked walls, and deteriorated sealant.
Left unaddressed, this can lead to equipment failure,
a shortened building lifespan, and even major repair costs.
To solve these problems, we offer a range of leak-prevention
and waterproofing solutions tailored to your building's condition and budget.

Protect Your Building from Water Damage
  • Heat-Reflective Waterproof
    Roof Coating

    Heat-Reflective Waterproof Roof Coating

    Two benefits in one:
    Waterproofing & Heat Reflection

    This method achieves heat reflection, waterproofing,
    and protection in coatings. It suppresses roof surface
    temperature rise while forming a waterproof layer to prevent leaks.

    Features
    • 3-in-1 function: heat reflection, waterproofing, and protection
    • Up to a 10-year warranty with our proprietary paint and high-quality installation
    • Lower cost than full re-roofing —
      applied directly over the existing roof
    • Ideal for a 10-year maintenance cycle
  • Spot Repair for Roof Leaks

    Spot Repair for Roof Leaks

    Low-Cost, Fast Emergency Response

    This method pinpoints and repairs the exact source of a leak — rust holes,
    loose hook bolts, gaps around skylights and vents. It's faster
    and cheaper than a full roof job, so it responds quickly to urgent leaks too.

    Features
    • Waterproofing based on structural understanding,
      not just silicone sealant
    • Lower cost and shorter lead time than
      full-scale work — fast emergency response
    • Focused on preventing recurrence, not just patching the surface
  • Roof Overlay

    Roof Overlay

    Long-Term Solution
    with No Impact on Production

    This method overlays new roofing material without removing
    the existing roof. Since there's no demolition, it can be installed
    without stopping production lines, and waste disposal costs
    are avoided. It's faster than a full replacement while securing
    long-term waterproofing and heat-reflection performance.

    Features
    • No removal of existing roof — minimal impact on production lines
    • No demolition or waste disposal costs
    • Choosing heat-reflective roofing material also
      achieves heat protection at the same time
  • Roof Replacement

    Roof Replacement

    Long-Term Leak Prevention

    When rust and deterioration have spread across the entire roof
    and spot repair is no longer enough, full replacement is the answer.
    It costs the most upfront, but it eliminates leak risk at the root
    and delivers long-term peace of mind.

    Features
    • Recommended for buildings 20+ years old
      with widespread rust or leaks
    • Lowers long-term costs compared
      to repeated spot repairs
    • Skylights, gutters, and other fittings
      can be renewed at the same time
    • Works even with hard-to-walk roofing materials
      like corrugated cement tiles
  • Rooftop Waterproofing

    Rooftop Waterproofing

    Stop Water Intrusion
    at the Rooftop's Root Cause

    Concrete rooftops require specialized waterproofing. Without
    re-waterproofing within about 10 years, water intrusion becomes
    unavoidable, causing indoor leaks and shortening the building's lifespan.
    By selecting the right waterproofing material and repairing
    the substrate properly, we build a maintenance plan
    matched to your required warranty period.

    Features
    • Waterproofing material selected
      to match the concrete deck structure
    • Careful substrate repair to bring out
      the material's full performance
    • Choose the method based on
      warranty period,
      for a long-term maintenance plan
    • Also suitable for buildings other than
      metal-roofed factories,
      such as office buildings
  • Exterior Wall
    Waterproof Coating

    Exterior Wall Waterproof Coating

    Wall Leak Prevention
    That's Easy to Overlook

    Leaks can also come from wall cracks and deteriorated sealant
    around windows. By repairing cracks and replacing the sealant
    before painting,
    we prevent this often-overlooked source of water intrusion at the root.

    Features
    • Elastic repair material for cracks
      prevents recurrence and discoloration
    • Sealant around windows is replaced
      before painting to improve durability
    • Early detection and repair of concrete spalling
      extends building lifespan
    • Low-dirt-pickup paint keeps the building looking good
      while preventing leaks
