Mortar Waterproofing Agent

Traditional mortar is naturally porous, but with our mortar waterproofing agent, you can transform standard cement mixes into high-performance, water-repellent barriers. We founded our company in 2003 with the mission to solve common construction failures like moisture seepage through masonry joints and renders. This mortar waterproofing agent is the result of 20 years of research into crystalline and hydrophobic technologies. It works at the microscopic level, filling capillary pores and creating an internal waterproof structure that won't wear off or peel away. Holding 60+ national patents, we have developed a formula that provides comprehensive protection while actually improving the workability and strength of the mortar mix.

As the earliest-established specialized manufacturer of mortar additives in Zhejiang, we understand the practical needs of the construction site. Our mortar waterproofing agent is highly concentrated and easy to dose, making it an efficient choice for large-scale projects where bulk material performance is critical. We have seen this agent used in everything from dam repairs to basement construction in the humid regions of East China, proving its reliability under extreme conditions. For our overseas clients, this additive represents a cost-effective way to upgrade local cement materials to meet international waterproofing standards. When you use our technology, you are benefiting from two decades of R&D and a factory-backed quality guarantee that middlemen simply cannot provide.

This agent is primarily used as an additive for masonry mortars, external wall renders, and basement screeds. It is the ideal solution for building "self-waterproofing" structures such as retaining walls, underground tunnels, and roof screeds. It is also widely used in jointing mortars and repair mortars to prevent moisture migration and the resulting damage to interior finishes.

Our factory is a National High-Tech Enterprise and a recognized industry leader in Zhejiang Province. We possess the largest and most advanced production lines for specialized mortar additives in the region, ensuring that we can meet the high-volume demands of international markets without sacrificing quality. Our 20-year history is marked by a consistent focus on innovation and solving the industry's most persistent waterproof challenges. By partnering with us, you are accessing a manufacturing legacy that values technical integrity and long-term partnership above all else.

Our Factory

As a technology-led manufacturer, we offer deep customization of the agent's concentration and chemical properties. Depending on the type of local cement and aggregates you use, our R&D center can fine-tune the formula to ensure optimal compatibility and performance. We can also provide the agent in various forms-liquid or powder-to suit your local construction preferences. Our OEM services allow you to package this high-performance additive under your own brand, backed by our 20 years of technical expertise.

Beyond standard masonry, this agent is essential for creating high-performance renders in coastal areas where salt spray and high humidity are constant threats. It is also heavily utilized in civil engineering projects, such as irrigation canals and sewage treatment tanks, where the durability of the concrete/mortar interface is vital. By reducing the permeability of the mortar, it also provides significant protection against freeze-thaw cycles, making it a valuable tool for construction in both tropical and temperate climates.
