Our Core Advantages
Material innovation. Technical excellence. Delivered by experts.
Proprietary Materials
Leveraging KXD Group's R&D capabilities, Xianghu utilizes proprietary waterproofing materials designed specifically for common aging building issues — roof leaks, wall seepage, and basement dampness. These advanced materials deliver high flexural strength and long-term durability, solving the traditional problems of membrane aging and frequent repairs.
End-to-End Service
From inspection and assessment through design, estimating, construction, and post-service follow-up — clients work with a single, accountable team from start to finish. This integrated approach eliminates subcontractor complexity, streamlines communication, and ensures quality control from diagnosis through delivery.
Extensive Experience
Our portfolio covers public infrastructure, aging commercial properties, and residential community repairs. We specialize in complex leakage issues caused by structural settlement and aging cracks, with proven success across multiple public and commercial projects.
Professional Technical Team
Our team of building restoration engineers and waterproofing project managers brings 3–5+ years of field experience, with deep knowledge of building structures, construction methods, and industry standards — capable of independent site assessment, technical proposal development, estimating, and construction management.
Compliant Industry Qualifications
As a KXD Group brand, Xianghu operates under the Group's construction enterprise qualifications, enabling us to undertake waterproofing, anti-corrosion, and thermal insulation projects in full compliance with national and industry standards.
Long-Term Warranty
We maintain a comprehensive follow-up and warranty program, proactively identifying potential issues after project completion. Our rapid response team addresses client concerns within committed timeframes — from material quality and workmanship to process control and after-sales support, ensuring every project stands the test of time.
Core Material of the 3rd-Generation Waterproofing System
Non-Oil Creep Rubber Waterproof Coating
A rubber-based coating made from modified SBR, butyl, and specialty rubbers, combined with DTI nanoparticles and grafted with high-viscosity polymers to form a paste-like flexible material that never releases oil. DTI nanoparticles (under 50nm) lock in oils for zero migration — delivering environmental safety, superior adhesion, and reliable waterproofing.
Our oil-control technology ensures zero oil migration up to 100°C — the material never cures, maintains tack, self-heals, bonds on contact, and resists peeling.
The material complies with T/CECS 534-2018 Technical Specification for Application of Non-Oil Creep Rubber Waterproofing Coating.
- Never leaks oil
- Never cures
- Superior elongation
- Self-healing
Waterproofing & Restoration Process
How We Deliver Waterproofing & Restoration Projects
Step 1:
Site Inspection & Design
Every waterproofing project begins with on-site inspection and problem diagnosis. Our team conducts comprehensive assessments of building structures, leakage causes, site conditions, and moisture risks — ensuring every solution is grounded in accurate, reliable data that provides precise technical support for construction.
Step 2:
Targeted Application
For different types of leakage (roof leaks, wall seepage, basement dampness, bathroom leaks, etc.), our team applies proprietary materials with targeted construction methods. Every process strictly adheres to industry standards, ensuring long-lasting and reliable results.
Step 3:
Quality Control
Upon completion, we maintain a comprehensive follow-up and warranty program, conducting regular inspections to verify long-term performance. Our rapid response protocol ensures continuous technical support and client assurance.
FAQ
Q1: Why do traditional waterproofing repairs often fail repeatedly?
Traditional repairs rely on grouting — injecting polyurethane or epoxy resins into concrete cracks. However, grout only temporarily fills gaps. When structural movement causes new cracks, the grout fails. Xianghu’s proprietary non-grouting process addresses the root cause, eliminating recurring leaks.
Q2: What is Xianghu's core technology?
Xianghu’s core technology combines our non-grouting repair process with the 3rd-generation waterproofing system — Non-Oil Creep Rubber Waterproof Coating. The material uses DTI nanoparticles to fully lock in oils, delivering eco-friendly, high-adhesion, and reliable waterproofing performance. With superior elongation and self-healing properties, the coating self-repairs immediately even when punctured under hydrostatic pressure — fundamentally solving water channeling issues.
Q3: How does Non-Oil Creep Rubber Waterproof Coating differ from traditional waterproofing materials?
Traditional bitumen-based materials such as non-curing asphalt leach solvent oils at high temperatures, corroding insulation boards and becoming brittle over time. Non-Oil Creep Rubber Waterproof Coating, however, remains stable at up to 130°C without corroding insulation. It never cures, maintains strong tack, self-heals, bonds on contact, resists peeling, and delivers significantly longer service life.
Q4: How long does the restoration take? Will it disrupt daily operations?
Xianghu uses advanced spray application methods, reducing project timelines by one-third compared to traditional membrane systems. Typical projects take 3–15 days depending on the scale and complexity. Phased work minimizes disruption to daily activities.
Q5: What is the warranty period?
With Xianghu’s 3rd-generation waterproofing system, warranty coverage ranges from 10 to 25 years. Standard waterproofing projects offer 5–10 years, depending on the project type and system used.
Q6: What are some representative projects?
Xianghu has extensive experience on complex projects, including roof restoration for 200 residential communities in Shanghai Fengxian, comprehensive restoration at China Railway West City, restoration at Shenzhen-Shantou Cooperation Zone Shenzhen Middle School, villa leak restoration at Zhongshan Huafa Eco-Garden, roof restoration at Zhongshan Creative Harbor, and roof restoration at Zhongshan Jiananhui. Project types span residential communities, schools, industrial parks, villas, and office buildings.
Q7: What industry credentials does Xianghu hold?
Xianghu is a drafter of China’s existing residential building renovation standards and holds a Class II qualification for waterproofing, anti-corrosion, and thermal insulation engineering — along with multiple product and process invention patents.
