Lining Pipes – Taking advantage of new technology, we are adding liners to the inside of aging sewer pipes to extend their life. The pipes to be repaired have bottoms that have eroded or rusted away. Pipe failures may occur at these locations which would result in more substantial repair costs. Little to no digging is involved in the lining process making for a less disruptive method than traditional "dig and replace" pipe repair methods.
Major Maintenance – A regular program of proactive vs. reactive maintenance fixes things before they worsen, saving money and minimizing disruption.
