Urban underground comprehensive utility tunnels are typical closed dark and humid environments with perennial water seepage, mold and microbial reproduction. The internal steel supports, cable bridges and equipment shells face long-term damp corrosion and microbial erosion. Ordinary paint is prone to mildew, blistering and rusting, which affects the safe operation of power and communication pipelines.

FLDC customized three-layer long-term moisture-proof and anti-microbial anti-corrosion system for underground pipe gallery steel facilities:

1. Deep penetrating moisture-locking primer: Block underground capillary water infiltration

2. Dense waterproof barrier intermediate coat: Isolate damp and mold medium

3. Anti-mold anti-corrosion weatherable topcoat: Inhibit microbial growth and long-term anti-rust

Core Advantages:

✅ Special adaptation to closed underground high-humidity dark environment

✅ Effectively resist underground water seepage and damp persistent erosion

✅ Long-term anti-mold and anti-microbial performance, no mildew breeding

✅ No peeling or blistering after long-term underground operation

✅ Extend service life of urban underground pipe gallery infrastructure

Widely used in municipal underground pipe gallery new construction and renovation projects. Contact us for engineering bidding documents.
