Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can

Counting the Drops

Leaks are never good, whether it’s a leaky boat or a leaky pipe system. Even advanced water utility systems can experience water loses ranging from 10 to 40%, with these losses being proportional to the population of the urban area serviced by the water distribution system. Large cities like New York,
