BEIJING URBAN-RENEWAL SOLUTIONS CO., LTD

Beijing Urban-Renewal Solutions is an innovation enterprise integrating materials R&D/production and construction services in the field of trenchless rehabilitation. We are committed to helping cities become safer, lower-carbon, and healthier.

• Sprayed and cured directly onto the prepared pipe wall to form continuous adhesion with the substrate — unlike many pre-fabricated liners that are primarily expanded/pressed against the host pipe.
• Improves interface integrity and load transfer, and helps reduce the risk of under-film pathways for leakage/corrosion.

• Sprayed in place to conform to bends, variable diameters, offsets, and irregular geometry.
• Eliminates seams and joints typical of prefabricated liner methods.

• Adaptable process parameters and equipment configurations for challenging sites, including inverted siphons, trench/river crossings, reducer (transition) sections, and single-entry (limited access) pipelines.
• Proven performance in extreme conditions: sub-zero temperatures (-21°C), high-temperature industrial applications (95°C+), and continuous-flow scenarios.

• Bonded-to-substrate lining is a key requirement for pressure-bearing systems — helping resist debonding, leakage pathways, and interface movement under internal pressure and external loads/groundwater pressure.
• Designed around the reliability and performance requirements of pressure-bearing systems.

• Trenchless, precision application that minimizes disruption to traffic and surrounding environments.
• Faster turnaround with reduced excavation, restoration, and overall project footprint.

• Proven deployment: Across major cities including Beijing and Guangzhou, spanning 10+ provinces and 25+ complex rehabilitation projects
• National recognition: Listed in a national advanced applicable technology/product directory
• Standards leadership: Active participation in compiling technical standards and related specifications for polymer spray lining trenchless rehabilitation
• Long-term performance: First domestic SIPP application (2005) continues stable operation after 20+ years
