Many storm water pipes from houses lead to a soakaway instead of being connected to a combined or a storm water mains. If your storm water from your house is going to a soakaway effectively the water from the roof of your house will be soaking away somewhere nearby your house under the ground.
If a storm water pipe is showing signs that it is not taking water away it would be wise to call us before the water causes a host of other more serious problems such as internal damp or structural issues at the foundation level of your house.
We can use the jetter to check whether the soakaway is blocked or whether it has reached the end of its useful lifetime. If it has reached the end of its lifetime we can give the best advice whether to re-route, alter the existing guttering or whether to take the plunge and install a new soakaway. If the only solution is a new soakaway we can help design and install a future proof soakaway which will keep the storm water away from your house for many years to come.
Soakaways can come in many different forms and we see the good bad and the ugly on a frequent basis. Examples of a bad soakaway would be a storm water downpipe going into the ground and going into earth where it goes into the ground. An OK soakaway would have a pipe underground leading at least 5 metres away from the building and heading into a pit of stone. A good soakaway would have had a percolation test done and then be designed so that it can take a large storm and not become saturated and back up. The soakaway area would be made from storm crates and it would be at least 5 metres away from the building.
Soakaways have an expiry date and depending on how well they are made and designed depends on how long they will last. As in life the better the soakaway is designed and installed the more it will cost to install BUT the longer it will last without any problems.
We would perform a percolation test to calculate the size of the soakaway required. Based on the percolation rate, the size of area taking the storm water and the historic 10 year storm data we can come up with an optimised size of soakaway that is required. This is the graph which is created from all the calculations. From the graph we can tell how large the soakaway needs to be to take any kind of storm based on the 10 year historic storm data:
We have designed many soakaways for schools, commercial buildings and domestic houses for roof water, ground water and even pool cleaning pump cycles. We have helped domestic customers claim for their new soakaways on their insurance where possible (see drainage insurance claims page) and all our installations are working well and are problem free to this day.
