Geosynthetic Clay Liner Tips: Types and Swelling Index
According to the international standard ASTM D5890 and the Chinese construction industry standard JG/T193-2006, high-quality bentonite used in GCLs should have a swelling index of ≥ 24 mL/2g. However, not all bentonite-based waterproof blankets can achieve this swelling index...

How to Maintain HDPE Geomembrane?
The geomembrane (such as HDPE, LDPE, PVC…) can be a "great contributor" to engineering anti-seepage. But if it is not properly maintained, the lifespan and performance can be greatly reduced. This guideline talks about how to take care of it and let it "live longer".

Geosynthetic Clay Liner Construction Guideline
In construction projects, waterproofing is always a key step. Geosynthetic Clay Liner (also named GCL orBentonite waterproof blankets), which is known for their self-healing ability and reliable performance, are becoming more and more popular in modern engineering. This guideline will break down what this material is all about and how to install it properly.

HDPE Geomembrane: The Hidden Shield for Autumn Aquaculture
Autumn isn’t just harvest season—it’s a stress test for pond water quality. If the water can’t stay clean and stable, disease risks spike and crops or aquatic life suffer. Chemical disinfectants like chlorine may help for a while, but they can also damage plants and the soil’s natural microbes. The smarter, eco-friendly move is to keep pond water and soil from touching in the first place.

How to ensure anti-seepage safety during typhoon weather?
In recent days, the eastern coastal regions of Asia have been affected by Super Typhoon Ragasa, which has brought a large amount of rain and strong winds. Such extreme conditions pose serious risks to infrastructure projects, weaknesses in waterproofing&seepage control and drainage systems. Structures like dams, reservoirs, landfills, tailings ponds and tunnels are facing high pressure and seepage risks, while roadbed often get trouble in insufficient drainage capacity.
Can Waterproofing Materials Prevent Fly Ash Pollution?
Fly ash is not ordinary dust visible to the naked eye. It is a pollutant generated during chemical processes, characterized by high corrosiveness and strong permeability, primarily originating from waste incineration. This substance can gradually disperse through water sources, thereby contaminating the surrounding environment...
