Designing With Geosynthetic Clay Liners
In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design barriers to liquids and gases using three types of GCL: single liners, composite liners, and composite covers. How...
DN 1200 Vitrified Clay Jacking Pipes with Intermediate Jacking Pit
The city of Peine in Lower Saxony lies in a sandy heathland between Hanover and Braunschweig.

Due to space limitations – the entire length of pipeline runs through a landscape conservation area, parallel to a trench – it was decided to install the vitrified clay pipes by...
Hydraulic capacity of ancient water conveyance systems to Ephesus
Ephesus was supplied by several long-distance water conveyance systems in ancient times. The 8 km long Şirince water conveyance system consists of baked clay pipes, and had a hydraulic capacity of around 10 l/s. The 7 km long Derbentdere water conveyance system consists also of baked clay pipes; and its hydraulic capacity was around 20 l/s. The 36 km long Değirmendere water conveyance system is a masonry conduit; its hydraulic capacity was around 200 l/s. The 42 km long Kayapınar water...
The Langer Connection
The call came from a Kennedy township homeowner that the smell of raw sewage was in the air and they were tired of the smell. Dave Gasparovich went out and started walking the very hilly area (15% grade or more) in search of the culprit. What he found was incredible, incredibly bad. The 12 manholes he discovered in the woods had been installed in the late 70’s and were connected with clay pipe. The smell was coming from these structures, some of which that had been almost totally destroyed by Hydrogen Sulfide...
