If your decades-old cast iron pipes are leaking in a few joints or have a few holes and crack here and there, it is a serious sign that the system is not going to last long. You might do some patchwork. But these temporary solutions are only for a few months or a year or two at...
All three pipes under test exhibited leaking before bursting, indicating that the concept of leak-before-break (LBB) could be used for pipe failure prevention. In addition, LBB provides valuable information that could be added to the pipe asset database to make better management decisions on ...
outlet choke points and poor directional flow transitions lead to flow inefficiencies and clogging. Inefficient flow or clogging of a downspout boot increases cause the leaking of water near the building foundation. Most downspout boots on the market are designed for ease of production, J.R. Hoe ...
The Two-layer lining method is a method of preventing cracking and breaking of grey cast iron pipes. Using a spray lining system which consists of an in-pipe spray gun, a flat angle spray nozzle and a resin supply system, a resin membrane of about 4 mm in thickness consisting of two ki...
