Polyurea Waterproofing Systems
Polyurea waterproofing systems use rapidly curing two-component pure polyurea (PETROUREA 300–800 family) sprayed with plural equipment to form seamless, abrasion-resistant coatings. Applications include industrial containment, selected tank linings, and specialty waterproofing where the designer specifies polyurea. Chemical media and immersion limits must be confirmed per project.

FAQ
- Is polyurea suitable for swimming pools?
- Only when the full system is designed for pool service and finishes. Many tiled pools use cementitious systems under tiles instead.
