The Great Wall, as an anti-seepage barrier across mountains and rivers, is a solid barrier built over thousands of years to withstand wind and rain, waterproof and consolidate territory. It has remained flawless and leak-proof despite the passage of time.
And Yigu, which is a benchmark for ingenuity in the field of home decoration waterproof accessories, has now launched the “Great Wall Tiangong” waterproof series, integrating Great Wall’s core spirit of being leak-proof and durable.

This series is equipped with the Great Wall homologous upgraded formula, innovatively developed three major anti-leakage black technologies imitating the Great Wall, and created a long-term anti-seepage system for the whole house that is complementary in rigidity and softness. It can reduce problems such as home decoration water seepage, wall moisture return, and base cracking from the source, and build a solid barrier for thousands of families to prevent moisture and leakage at home.
The first is “Great Wall Tiangong·Solid Defense”, which is a special rigid waterproofing for walls and is suitable for waterproofing the whole house wall.
The core of the product is equipped with the Great Wall’s dense anti-leak technology, which replicates the Great Wall’s layered, compacted and airtight construction principles to create an all-round dense solid waterproof protective layer and build a hard and stable wall waterproof base.
It has three core properties: dense impermeability, super aging resistance, and healthy and environmentally friendly.
The rigid structure is dense and gap-free, which can effectively block the penetration of water vapor and the return of moisture and mold on the wall. It has strong adhesion, provides a solid base for tiles, effectively avoids water seepage and hollowing, and maintains the first line of defense for wall waterproofing with long-term rigid protection.
Then there is “Great Wall Tiangong·Tough Defense”, which is a flexible waterproofing for the ground, specially developed for scenes where the home decoration floor is prone to deformation and cracking.
It is equipped with Great Wall-like modified anti-cracking black technology, which reshapes the waterproof membrane structure through a special modification process to create a highly elastic and flexible protective system that can adapt to various working conditions such as thermal expansion and contraction of the ground base, fine settlement, and tensile deformation.
The product has the core advantages of flexibility, crack resistance, beautiful color, and long-term waterproofing, effectively solving the industry pain points of traditional floor waterproofing that is prone to cracking, peeling, deformation, and leakage.
The high-elastic membrane layer can freely expand and contract with the deformation of the ground, is non-cracked, non-permeable, water-resistant and corrosion-resistant. It has a unique color scheme with high recognition and convenient construction, and can build a strong waterproof safety barrier for home decoration floors in all aspects.

The last is “Great Wall Tiangong·Jiu Defense”, which is a universal rigid and flexible waterproof for walls and floors, suitable for waterproofing in whole house decoration.
Equipped with the Great Wall’s rammed fiber anti-leakage black technology, it draws on the core principles of layered ramming and three-dimensional protection of the ancient Great Wall method, and integrates fiber composite proportioning technology to create a multi-level three-dimensional anti-leakage structure of “rigid anti-seepage + flexible anti-cracking” to achieve extremely tight waterproof protection.
The product combines the three core features of multi-level leakage resistance, super strong bonding and efficient construction, and is perfectly compatible with all-scenario construction on walls and floors. It can not only continue the dense and impermeable advantages of rigid waterproofing and block water vapor penetration in the wall, but also have the high elastic and crack-resistant performance of flexible waterproofing, and is suitable for ground deformation protection.
It is suitable for a variety of base materials, and the construction is simple and efficient. It can complete the whole house waterproofing construction in one step, saying goodbye to the problems of zoning material selection and cumbersome construction.
“Great Wall Spirit·Yigu Quality” is Yigu’s original intention to deeply explore the field of waterproofing, and it is also the core core of the “Great Wall·Tiangong” waterproof series.
Relying on three anti-leakage technologies and three professional waterproof products, Yigu integrates Great Wall’s thousand-year waterproofing and soil-fixing construction wisdom into every product and every home decoration protection.
Yigu’s “Great Wall Tiangong” waterproof series combines rigidity and softness to prevent leakage, providing full-house protection without blind spots. It takes into account the needs of various waterproofing scenarios in home decoration and engineering. It reshapes the industry’s waterproof quality benchmark with Great Wall-level stringent protection standards, making the home space permanently dry and clean, and safe and leak-free year after year.
