Daisin Partners with Leju to Host Construction Forum Focusing on Waterproofing Quality and Information Transparency in New Developments

As consumer standards for housing quality significantly increase, location and price are no longer the sole criteria for homebuyers. Building durability, living comfort, and long-term maintenance costs are now key decision-making factors.

To examine the invisible core affecting building lifespan and brand trust—"waterproofing work"—Daisin Waterproofing partnered with Leju Technology to host a construction forum. Daisin General Manager Kang Yongxin and Leju Technology Founder Li Yinong jointly discussed causes of leaks, protective mechanisms in construction methods, and a homebuyer’s leak-prevention guide, and announced plans to advance waterproofing information transparency.

### The Core of Seepage Risks: Detail Workmanship and Standardized Management

Regarding the main causes of leaks in new developments, Daisin General Manager Kang Yongxin pointed out that seepage problems mostly stem from inadequate implementation of standard operating procedures in detailed construction, rather than defects in individual materials. High-risk areas include joints between window frames and exterior walls, bathroom corners, around pipes, and drain outlets—locations where different trades intersect. If these areas are damaged by subsequent electrical or tiling work after waterproofing is completed, hidden risks are created.

In response, Daisin advocates integrating four core elements—materials, methods, details, and management—to enforce full-process quality control from substrate preparation and node construction to inspection and handover.

### Waterproofing Performance and Information Transparency

On waterproofing durability and seismic resistance, Daisin stated that waterproofing systems cannot be evaluated solely by fixed timeframes or earthquake magnitudes. The key lies in using materials with high elasticity and crack resistance, capable of maintaining protection even when micro-cracks form in the structure.

Moving forward, Daisin plans to collaborate with Leju’s platform to publicly disclose project information for buildings using Daisin’s waterproofing solutions, enabling buyers to compare and reference data when purchasing homes.

### Homebuyer Leak-Prevention Guide: See, Ask, Trust, Verify

To help homebuyers avoid leaking pitfalls, Daisin recommends evaluating through four aspects: "See the Method, Ask about Warranty, Trust Reputation, Verify Testing."

Before purchase, buyers should clarify the waterproofing method used, application scope, warranty terms, and the contractor’s market reputation. Prior to handover, they must confirm whether water testing was conducted post-construction and inspect high-risk areas such as window frames, exterior walls, balconies, bathrooms, and rooftops during property inspection.

Daisin emphasizes that waterproofing should be based on proactive quality management rather than reactive repairs. By advancing information transparency, the company aims to transform this invisible engineering into a verifiable architectural value, effectively safeguarding homebuyers’ rights.
