Geomembrane Design Part 1: How Gas Bubbles Form
Many geomembrane lining systems fail in wastewater treatment ponds and in ponds in the plantation and livestock sectors. Geomembrane gas bubbles that form beneath a lining system are usually caused by a chain of events: the lining system leaks, liquid collects under the geomembrane, methane gas forms, and the trapped gas gradually lifts the geomembrane.

How to Increase Salt Pond Yield with HDPE Geomembrane
One of the largest salt-producing regions in Indonesia lies along the coast of Java, particularly in East Java province. Its long dry seasons make the region well suited to salt production, and farmers are always looking for ways to increase salt pond yield. Conventional methods produce very low yields. Salt farmers channel seawater into holding […]
Expansive Soil Treatment Methods
Expansive soil treatment is needed because expansive soil has a high potential to swell and shrink. This behavior generally results from changes in water content that alter the soil volume. Infrastructure built on expansive soil often suffers damage from ground movement. This movement occurs when changes in soil water content during the dry and rainy […]
