Waterproofing for Roads (YNM-124) is a liquid-applied waterproofing system manufactured by YNM Safety for bridge decks, culverts, box drains, retaining structures and concrete pavements. Water ingress is the single largest cause of premature deterioration in road structures — it carries chlorides to embedded reinforcement, drives corrosion, and leads to spalling, delamination and eventual structural repair at many times the cost of the original waterproofing.
The system is applied as a seamless, cold-applied membrane that cures to a flexible film with crack-bridging capability, accommodating the thermal movement and live-load deflection that rigid coatings cannot tolerate. Because it is liquid-applied, it seals around drainage outlets, kerb junctions, expansion joints and service penetrations where sheet membranes are most likely to fail.
YNM-124 is specified on highway and expressway bridge decks, ROB and RUB structures, culverts and box drains, subway and underpass slabs, retaining walls and reservoir-adjacent pavements where long-term protection of the concrete substrate is required.

Road & Bridge Deck Waterproofing Market
Bridge asset management, ROB/RUB programmes and rising lifecycle-cost awareness are driving structural waterproofing demand in India and export markets.
Road waterproofing manufacture focuses on polymer selection, elongation testing and water-tightness verification on every batch.
Acrylic and PU polymer dispersions tested for solids, pH and particle size.
Graded fillers and extenders selected for film build and crack-bridging.
Pigments and fillers dispersed under high shear to a uniform paste.
Polymer added under controlled agitation to avoid shear coagulation.
Thickeners dosed so the film holds thickness on slopes without sagging.
Cured film tested for elongation at break and crack-bridging performance.
Batch samples tested under head of water for specified duration.
Filled into lined pails and drums with tamper-evident seal.

Answers about this product from YNM Safety—manufacturing, standards, supply, and support.
Water entering a deck carries chlorides to the embedded reinforcement, which drives corrosion, spalling and delamination. Waterproofing the deck before the wearing course is laid protects the structure and defers major repair that costs many times more than the original membrane.
YNM Safety supplies a cold liquid-applied membrane. Because it is liquid-applied it forms a seamless film with no laps, and it seals reliably around drainage outlets, kerb junctions and service penetrations where sheet membranes most often fail.
Yes. The system is designed to be overlaid with a bituminous wearing course once fully cured. Share your deck build-up and paving schedule so the correct grade and cure window are confirmed.
The cured film is flexible and crack-bridging, so it accommodates thermal movement and live-load deflection that rigid coatings cannot tolerate. Moving joints are detailed separately with reinforcing fabric.
The substrate must be sound, clean and free of laitance, curing compound and standing water. Blowholes and honeycombing are filled, and a primer coat is applied where the concrete is highly absorbent.
