Product Description
Non‑curing Rubber Bituminous Waterproof Coating with Strong Self‑healing Property
Product Introduction
This product is refined by high-temperature mixing with base bitumen as the raw material, added with polymer rubber modifiers, anti-aging additives and high viscoelastic components. It is a flexible waterproof sealing material that permanently maintains viscoelastic paste form. It never cures or hardens at ambient temperature and features continuous creep self-healing performance. It can be tightly compounded with SBS/APP waterproofing membranes and cement substrates. Constructed via hot scraping and high-pressure spraying, it fills tiny cracks and voids on the base to form a seamless integrated waterproof sealing layer, which thoroughly solves leakage problems caused by substrate deformation and cracking of buildings. It is widely applied to various waterproof projects for underground structures, roofs and tunnels.
Product Features
-
Permanently non-curing with excellent self-healing performance It keeps thick viscoplastic state permanently without hardening or cracking. When tiny cracks appear on the substrate, the material can flow and fill gaps automatically to eliminate water seepage paths fundamentally.
-
Outstanding adhesion and sealing performance It bonds tightly with various substrates including bitumen membranes, concrete, color steel plates and geomembranes, without delamination or hollowing. It provides tight sealing at lap joints with no hidden risk of water channeling.
Application Scope
-
This product is suitable for various non‑exposed waterproofing projects. It can be used in composite systems with waterproof membranes, and also for renovation & repair of existing waterproof layers.
- Roofs and side walls of industrial & civil buildings, green roofs;
- Underground projects including basement slabs, side walls, roof slabs, subways, tunnels and utility tunnels;
- Municipal traffic projects such as roads, bridges and railways;
- Hydraulic facilities including dams and pools;
- Sealing & joint filling for details: expansion joints, settlement joints, internal/external corners and pipe penetrations;
- Ideal for substrates with large deformation and cracking risks. Acceptable for construction on wet substrates.
