Zheng Sai Technology - Geological disaster prevention has been verified once again

In 2022, Zhengsai Technology, in collaboration with Professor Qie Zhihong's team from Hebei Agricultural University, conducted an integrated experimental section of redundant resilient ecological sustainable slope reinforcement and greening at the Chinese Academy of Sciences Soil and Water Conservation Base in Yixian County, Hebei Province. To verify the anti-scouring performance, anti-frost heaving performance and durability of Zhengsai redundant resilient sustainable technology under extreme conditions of heavy rain, thereby providing a new solution to the problem of soil erosion.

In late July and early August 2023, Yi County, Hebei Province, was hit by an extremely heavy rainstorm. From 5:00 on July 28, 2023 to 13:00 on August 1, 2023, the cumulative precipitation was 540mm.

After the heavy rain, an assessment was conducted and it was found that apart from local damage to the planting surface layer, no landslides or soil erosion occurred on the slope

In September 2023, it was found that moss had naturally grown on the base surface of the damaged area.

This torrential rain verified the correctness of Zheng Sai's redundant protection concept: grass doesn't run away in heavy rain. The miraculous effect of the extremely heavy rain slope is not destroyed.

In July 2025, Yi County, Hebei Province, was once again hit by an extremely heavy rainstorm. This rainfall is the most intense one since the Chongling Observation Field in Yi County began its observations. It lasted for a short time but was very heavy. The meteorological field installed a rain gauge for observation from 18:35 on July 24, 2025 to 09:25 on July 25, 2025. The cumulative rainfall was 311.8mm, lasting for 890 minutes, with the maximum rainfall intensity reaching 81.6mm/h

Observe the Zhengsai Technical Slope after the rain：

After observation, it was found that no landslides or soil erosion occurred on the Zhengsai Slope during the torrential rain in Yi County, Hebei Province in July 2025.

In other areas, the slopes that were not treated by Zhengsai technology were severely damaged：

Time and practice have proved that Zheng Sai's redundant protection technology has a magical effect in soil and water conservation, flood and drought relief rescue, and geological disaster prevention. In the face of irresistible natural forces, losses can be significantly reduced, people's property safety can be protected, and thus sustainable economic and environmental development can be achieved
