Cement based permeable crystalline waterproofing

Send Inquiry
Product Introduction

Cement based permeable crystalline waterproof coating is a powdery rigid waterproof material made from special cement, quartz sand, etc. as the base material, infiltrated with various active chemical substances. After interacting with water, the active chemical substances contained in the material penetrate into the interior of the concrete through the carrier water, forming insoluble crystals in the concrete, blocking capillary pores, and making the concrete dense and waterproof.


Product number: LD-2601

Product specifications: 18KG


Product features

1. A waterproof system with inorganic materials that never lose their effectiveness.

2. Can withstand high water pressure for a long time up to a water head of up to 00 meters.

3. The self-healing performance can self heal 0.4mm suspected soil cracks.

4. Excellent construction performance on the back surface solves the problem of a large number of basement flattening

5. Non toxic, environmentally friendly, anti-corrosion, alkali resistant, can improve the strength of mixed soil.

6. The leveling layer and protective layer are needed to save construction time, accelerate construction progress, and significantly reduce overall construction costs.

7. A waterproof system that never fails can continue to function when other waterproof systems fail.

8. It has a transparent shoulder and can draw the fine pores of the main shadow of the person who is suspected to have formed a structure inside the concrete through chemical reactions


Widely used with high cost-effectiveness

1. Waterproofing for the project

2. Roof waterproofing

3. Window sills

4. External wall waterproofing

5. Waterproofing of the bathroom

6. Waterproofing of the pool


Construction technology 

01 Clean the base surface to ensure it is intact, free of dirt and water

02 Moisturizing the base surface to ensure it is moist, but there should be no visible water present

03 Mix with water, add an appropriate amount of water, and stir evenly

04 Apply thinly and evenly for the first time, not too thick

05 Apply the second coat vertically after the surface dries

06 Spray a small amount of water for maintenance when the surface is too dry


Matters needing attention

1. Base treatment: The base treatment process is an important factor in determining the success of waterproof construction. It should be ensured that the base surface is free of floating dust, grease, holes, cracks, non-standard construction joints, and mesh cracks. High pressure water guns can be used to clean and remove surface attachments, honeycombs, and loose parts.

2. Before construction, the base surface should be fully wetted to facilitate the infiltration of crystalline active components into the interior with the help of water. But it should be noted that there should be no visible water on the base surface.

3. Leakage points, seams, and surfaces should be treated first before proceeding with large-scale construction. The key waterproof areas should be reinforced or crack resistant by increasing the amount of materials used.

4. Ensure the integrity of the construction coating and ensure the required amount of construction.

5. Pay attention to the construction temperature and do not carry out construction in an ambient temperature below 5 ° C.

6. If decoration or other surface layers are required on the outer side of the waterproof structure, scraping construction can be used to improve the density and cohesion of the waterproof coating of the permeable structure, ensuring that the decorative surface layer is firmly bonded and free of voids or delamination.

7. Construction maintenance is a crucial factor in ensuring that waterproof structures meet standards. After the construction of the waterproof coating for permeable structures is completed, water should be sprinkled for curing as soon as the coating starts to dry. The curing period is 2-3 days, with a water spraying interval of about 4 hours. Wet burlap or grass cover can also be used for curing.

8. In long-term immersion environments, the waterproof layer should be cured for at least 14 days before it can store water.
