Underground Services Existing properties tend to be more difficult than new homes. This is due to other services like water, communication and drainage running where proposed stormwater drains will go, paving and concrete paths already laid, soil has roots or has become very difficult to excavate.
Traffic If the piping or leach drains are being put in an area where traffic is likely to park on top of them, more sturdy products are likely to be used that can handle the weight of vehichles.
Why stormwater can block up The most common reasons for stormwater to block up are; Incorrect piping grades, meaning the fall of the pipe is not steep enough for water to run down. A broken pipes, undersized pipes, pipes filled with sand or leaves and lastly your leech drains being full.
What to do if your stormwater is blocked Blocked stormwater is usually handled the same way as a general sewerage blockage on your propery. If your system is holding water, we first put down our High pressure water jetter machine. If there's an obstruction or its full of sand and leaves, this will sort it. If the issue persists or we cannot unblock it. A pipe camera and locator will be needed to locate the cause of the issue and then that segment of pipe will likely get dug up and replaced.
