PB-II Polymer Modified Asphalt Waterproof Coating

Black, 50kg Drum Pack

Caberry PB‑II polymer modified asphalt waterproof coating is an upgraded rubber-crosslinked bridge deck waterproofing variant of the PB series. The rubber phase inside modified asphalt forms a continuous, interpenetrating and crosslinked network to achieve high polymer performance. It is engineered for highway and municipal bridge decks, capable of enduring long-term vehicle loads and compressive stress, preventing water-induced structural damage and extending bridge service life.

• Non-toxic, odorless, eco-friendly, cold construction without heating.
• Rubber forms continuous interpenetrating crosslinked network in modified asphalt for superior polymer performance.
• Cured film retains rubber elasticity and excellent low-temperature flexibility.
• High shear strength, withstands long-term compression and dynamic load on bridge decks; stops water penetration damage and prolongs highway bridge lifespan.

Workflow: Base cleaning → Detail reinforcement → 1st waterproof layer → 2nd waterproof layer → 3rd waterproof layer → Curing & maintenance → Asphalt concrete paving

1. Thoroughly clean the bridge slab, remove dust, laitance, loose particles and oil stains.
2. Apply reinforcing coats on critical zones: drain outlets, expansion joints, inner and outer corners.
3. Apply coating evenly by spraying machine, brush or roller in three separate coats.
4. Allow full curing of each coat before applying the next layer.
5. Complete curing period must be finished before paving hot asphalt overlay.

Q: What is the difference between PB‑I and PB‑II?
A: PB‑I is formulated for higher shear performance for heavy-load bridges; PB‑II is the mainstream standard grade with stable comprehensive performance, more cost-effective for general highway and municipal bridge projects.

Q: Is PB‑II cold-applied?
A: Yes, no heating required, safer and easier for field construction.

Q: Can PB‑II replace FYT‑1 / AMP‑100?
A: It can be selected according to tender specification; all are compatible with hot asphalt overlay.

Q: Can you provide official test reports for bidding?
A: Yes, complete inspection documents are supplied for road and bridge tender submission.

Q: Can you provide English TDS and MSDS?
A: Yes, complete English technical documents ready for customs clearance.
