Aquaculture Pond Concrete Blanket

Our Aquaculture Pond Concrete Blanket is equipped with a self-sealing structure, anti-erosion, anti-frosting and anti-cracking properties. Compared with traditional poured concrete and brick and stone retaining walls, the construction speed can be increased by more than 70%. It generates no construction waste and requires no post-construction maintenance. It is a new generation of highly efficient protective material for water conservancy retaining walls, ditch lining, slope protection, and emergency rescue.

Field Engineering Case Basic Information

• Project Location

Renhe Farmland Irrigation Canal Renovation Project in Shandong Province

• Construction Period

June 2022

• Project Scale

A total length of 2,300 meters trapezoidal farmland water diversion channel. The original earthen ditch suffered severe soil erosion, with frequent water leakage, seepage, and collapse during rainy seasons.

• Selected Products

10mm national standard thick Aquaculture Pond Concrete Blanket

• Project Conditions

Outdoor open-air construction, with significant temperature differences throughout the year. During summer, concentrated rainfall causes strong water flow erosion, while in winter, there is obvious freezing expansion. The requirements are for quick construction, zero maintenance in the later stage, while also combining seepage prevention with slope protection.

Usage Effect

• Efficient and time-saving construction: No need for mixing concrete or building brick scaffolding throughout the process. Workers simply lay the blanket and water it directly. Compared to traditional concrete construction, the overall project duration is shortened by two-thirds, significantly reducing labor costs.

• Completely solve leakage and collapse problems: After curing, the entire ditch becomes seamless and integrated. It completely eliminates the problems of water seepage and water loss from the ditch body. The slope is stable and firm. Even after three consecutive years of heavy rain during the flood season, there is no collapse, no hollowing out, or cracking and falling off.

• Strong weather resistance and durability: After three years of temperature differences between winter and summer, rain, snow, freezing and thawing cycles, the surface layer of the cement blanket remains intact without weathering or damage. The strength always meets standards. No need for annual manual repair of the ditch.

• Extremely low operation and maintenance costs: Once the construction is completed, there is no need for maintenance or cleaning in the future. The water channel's water delivery efficiency is significantly improved, and the water utilization rate for farmland irrigation is greatly enhanced.

Customer's Genuine Feedback

Previously, the earthen water channels suffered from continuous leakage and frequent collapses during the rainy season. Every year, it was necessary to spend money on manual dredging and repair work, which was both time-consuming and costly. After switching to the Aquaculture Pond Concrete Blanket, the channel could harden by simply being watered. The construction process was extremely convenient. After three years of use, the channel remained intact without any damage or collapse. No maintenance was required throughout the process. It was much cheaper than brick masonry and cast-in-place concrete, and was highly suitable for the slope protection project of farmland water channels.

FAQ

Q1: Will the concrete cement mats used in fish ponds release harmful substances that could affect the survival of fish, shrimp, and crabs?

No. This product is formed by a special ratio of dry cement aggregate and three-dimensional fibers. It contains no toxic admixtures or heavy metal additives. After curing, the structure is stable and no free alkaline substances are released. It will not change the pH value and ammonia nitrogen index of the fish pond water, nor will it cause stress or death to aquatic animals. It is fully suitable for freshwater aquaculture and pond water storage conditions, and is a special protective building material for ecological aquaculture.

Q2: How to accurately select the thickness specifications of the fish pond cement blanket to adapt to different fish ponds?

For shallow water rearing ponds, small reserve fish ponds, and temporary fish breeding enclosures, the recommended specifications are 6mm and 8mm; for regular adult fish breeding ponds, standardized farmland fish irrigation channels, and ordinary pond slopes, the preferred main flow common specifications are 10mm and 12mm; for deep water breeding ponds, main drainage and water intake channels, and ponds with perennial high water flow erosion, the recommended specifications are 15mm and 18mm thickened models; in areas with severe cold and large temperature differences, the anti-freezing enhanced version can be directly selected.

Q3: The temperature in the aquatic pond varies greatly throughout the year and there are frequent freeze-thaw cycles in winter. Will the cement blanket crack, powder off or fall off?

After the proper selection and construction, there will be no damage problems. The standard breeding model can withstand a wide temperature range of -30℃ to 70℃, with excellent resistance to ultraviolet rays, aging, and freeze-thaw; ordinary conventional ponds can survive the winter stably. In cold and high freeze-thaw areas, it can be used in combination with the anti-freeze enhanced model, effectively resisting winter expansion and summer high-temperature exposure. The outdoor aquatic pond can last for over 30 years without powdering, cracking or falling off.

Q4: There are many irregular curved surfaces at the bottom of the fishpond and on the arc-shaped pond slope. Can the cement blanket fit perfectly and not become loose or peel off?

Aquaculture Pond Concrete Blanket can perfectly adapt to various irregular base surfaces of fishponds. The product has extremely strong flexibility in the dry state and can be bent and cut at will. It can closely fit the arc-shaped edges of the fishpond, the corners at the bottom of the fishpond, and uneven base surfaces with irregularities. No extensive secondary cutting and patching is required. Combined with the standard laying and watering process, the formed product has strong overall integration, without any suspension, no emptying, and no peeling or detachment. It is suitable for all standardized and irregularly modified fishponds.

Q5: Compared to geotextiles and cast-in-place concrete, what are the advantages of the fishpond-specific cement blanket in terms of long-term operation and maintenance?

The advantages over traditional materials are significant: Compared to geotextiles, this product becomes hard and wear-resistant after curing, is resistant to fish and shrimp punctures, and is less prone to damage and aging; compared to cast-in-place concrete, the construction speed is increased by more than 70%, and there is no need for formwork and mixing, and no construction waste. Once laid, it does not require annual dredging and repair, nor frequent maintenance. It can resist water flow erosion and soil erosion for a long time, significantly reducing the labor and renovation costs for the later operation and maintenance of aquatic farming.
