Advanced Waterborne Bitumen Emulsion
(Sub-Grade Damp-Proofing & Liquid Detailing Specification)
Product Overview
The engineered liquid-applied membrane designed for rigorous subterranean environments and complex structural geometries. Formulated from a proprietary polymer-modified emulsified asphalt, this 100% waterborne system delivers elite elastomeric performance with exceptionally low vapor permeability. It serves as both a formidable standalone damp-proofing barrier for below-grade structures and the ultimate “Liquid Detailing” companion for SBS/APP composite membrane systems.
Core Advantages
Rapid “Tack-Free” Curing Technology: Engineered to accelerate critical-path construction.
The advanced formulation dries rapidly to a durable, tack-free finish. This prevents job-site contamination (no tracking of bitumen), resists foot traffic adhesion, and allows for immediate backfilling or subsequent assembly applications. Seamless Complex Detailing (Liquid Flashing): The flowable, high-build rheology perfectly conforms to irregular architectural shapes, pipe penetrations, and critical junctions. It eliminates the vulnerabilities of cutting and folding sheet membranes at complex corners, providing a foolproof, monolithic seal. Sub-Grade Hydrostatic & Vapor Defense: Creates a continuous, highly elastic barrier that actively bridges dynamic substrate micro-cracks. Its exceptionally low vapor permeability provides impenetrable protection for basements, retaining walls, and deep-foundation footings against aggressive ground moisture. Damp-Tolerant & Eco-Compliant: The zero-VOC, water-based chemistry is environmentally benign and entirely non-flammable. It aggressively bonds directly to damp “green” concrete surfaces without blistering, drastically reducing surface preparation wait times.
Engineered Applications
▪ Deep subterranean damp-proofing for basements, retaining walls, and foundation columns.
▪ Critical liquid detailing and flashing for pipe penetrations, internal/external corners, and structural joints.
▪ High-performance composite primer and integration layer for SBS/APP bituminous sheet membrane systems.
▪ Concealed structural repair works requiring high-elasticity crack bridging.
System Integration: The Subterranean Detailing & Damp-Proofing Matrix
To fully exploit the “Liquid Detailing” capabilities of this advanced bitumen emulsion, you must respect the physical limits of a liquid-applied film. While it conforms perfectly to complex geometries, a liquid membrane cannot bridge gaping structural voids, adhere to oxidizing metals, or form molecular bonds with smooth plastics. Attempting to use liquid bitumen as a standalone cure-all for complex pipe penetrations and 90-degree cold joints guarantees capillary failure. Secure your subterranean envelope by integrating these mandatory detailing components:
Cold-Joint Profiling & Hydrostatic Void Elimination:
Must pair with: Industrial Ultra-Rapid Setting Hydraulic Cement
Why it’s critical: Subterranean foundation walls meet footers at a sharp 90-degree angle—the highest risk zone for structural settlement. Brushing a liquid emulsion directly into this sharp internal corner guarantees micro-tearing as the coating cures and the building shifts. This ultra-rapid hydraulic matrix must be deployed to construct rigid 45-degree cant strips (fillets) at all wall-to-floor junctions, providing a flush, crush-proof transition that neutralizes shrinkage and structural stress before the liquid bitumen is applied.
Dissimilar Material & PVC Penetration Gas-Lock:
Must pair with: Architectural High-Performance PU Sealant
Why it’s critical: The most vulnerable points in any subterranean damp-proofing system are the PVC utility pipes and drain penetrations. Bitumen emulsion physically cannot form a permanent chemical bond with smooth, rigid plastics. Brushing the emulsion directly against a PVC pipe guarantees water tracking and gas migration. This dynamic polyurethane sealant must be heavily extruded around all pipe boots to create an elastomeric, watertight, and gas-tight gasket that the bitumen emulsion can seamlessly overlap.
Dynamic Crack Reinforcement (The Skeletal Detailing Matrix):
Must pair with: High-Tenacity Elastomeric Flash-Bond Matrix
Why it’s critical: When using this emulsion to repair structural micro-cracks or seal joints between concrete panels, the high elasticity of the bitumen is insufficient if the crack widens under active settlement. Applying this cold-applied, non-woven butyl tape directly over the cracks acts as a high-tensile structural “skeleton.” The liquid emulsion seamlessly absorbs into the tape’s fleece surface, creating a reinforced, tear-proof composite over the building’s moving parts.
