Vertical-Grade Aromatic PU Coating
(High-Build Thixotropic & Zero-Slump Specification)
Product Overview
The definitive labor-saving liquid membrane for steep-slope and vertical sub-grade waterproofing. Formulated from a premium aromatic polyurethane matrix, this single-component system utilizes advanced Thixotropic Rheology. It remains highly workable during trowel or airless spray application but instantly locks into place upon contact with the substrate. Designed specifically for concealed environments, it delivers a monolithic, heavy-duty elastomeric barrier without the relentless sagging common in standard liquid applied membranes.
Core Advantages
▪ High-Build “One-Pass” Productivity: Engineered for massive labor reduction on vertical applications. The extreme anti-sag formulation allows contractors to achieve a massive Dry Film Thickness (DFT) of >0.8 mm (30+ mils) in a single pass. This eliminates the need for multi-coat staging, significantly accelerating the critical-path construction schedule.
▪ Advanced Thixotropic Shear-Thinning: The intelligent chemical matrix provides effortless flow through spray equipment or under a trowel, yet exhibits Zero-Slump behavior on vertical and inverted surfaces. It ensures absolute uniform thickness across foundation walls without material pooling at the base.
▪ Cold-Climate Elastomeric Memory: Once cured, the aromatic matrix maintains profound flexibility even in freezing, subterranean conditions. It actively bridges structural settlement cracks in foundation walls, preventing groundwater intrusion under dynamic hydrostatic pressure.
▪ 1K Rapid Deployment: The moisture-curing, single-component formulation requires no complex on-site mixing, no plural-component heating rigs, and no open flames. It provides immediate, out-of-the-pail readiness for fast-paced trench and retaining wall projects
Engineered Applications
▪ Vertical foundation walls, retaining walls, and blind-side concrete forms.
▪ Concealed waterproofing for pitched roofs and complex architectural domes.
▪ Subterranean planter boxes and deep-excavation elevator pits.
▪ Any non-exposed structural waterproofing requiring high-build vertical application.
System Integration: The Vertical Sub-Grade Defense Matrix
To guarantee absolute watertight integrity on vertical foundation walls and deep-excavation pits, relying solely on a high-build coating is a fatal engineering miscalculation. Earth backfill, structural settlement, and inherent concrete pouring defects will aggressively compromise an unsupported liquid barrier. Eliminate hydrostatic vulnerabilities, secure form-tie penetrations, and guarantee continuous adhesion under gravity by integrating these mandatory sub-grade components:
Wall-to-Footer Cold Joint Fortification:
Must pair with: Industrial Ultra-Rapid Setting Hydraulic Cement
Why it’s critical: The 90-degree cold joint where the vertical foundation wall meets the horizontal footer is the absolute highest-risk zone for hydrostatic water intrusion. A liquid membrane, even a high-build thixotropic one, will thin out and tear at this dynamic junction. This ultra-rapid hydraulic matrix must be deployed to construct a rigid 45-degree cant strip (fillet) along the entire wall base, redirecting water pressure and providing a seamless transition for the liquid coating.
Form-Tie & Utility Penetration Sealing:
Must pair with: Architectural High-Performance PU Sealant
Why it’s critical: Poured concrete foundation walls are inherently riddled with snapped form-tie holes, honeycombing, and utility pipe penetrations. Applying a liquid coating directly over these deep voids creates hollow air pockets that will instantly burst under the pressure of soil backfill. This Class 25 F dynamic polyurethane sealant must be heavily injected into every form-tie cavity and around all pipe boots, creating a flush, elastomeric plug before the main vertical coating is sprayed.
Anti-Sag Capillary Anchoring & Vapor-Lock:
Must pair with: Elite Vapor-Lock & Pore-Sealing Epoxy Matrix
Why it’s critical: Applying a massive 30+ mil thickness of liquid polyurethane onto a vertical wall generates significant gravitational pull on the coating-to-concrete interface. Furthermore, newly poured foundation walls actively out-gas, which causes large blisters in the waterproof membrane. This specialized epoxy primer penetrates the vertical capillary network, neutralizing out-gassing and creating a brutal molecular anchor that permanently secures the heavy-duty PU layer against gravity and negative vapor drive.
