Nature abhors a vacuum, and it loves a water source. Tree roots are remarkably resourceful. If there is a tiny gap in the membrane or a crack in the pipework leading to the soakaway, roots will invade. Once inside, they create a net that catches debris, leading to rapid blockages. In severe cases, large roots can physically crush the soakaway crates or pipes, causing the ground above to subside.
Geology is destiny when it comes to drainage. Many soakaway failures are not the fault of the installation, but the soil itself. Heavy clay soils are notorious for poor percolation. If a soakaway is installed in clay without proper calculations or depth, it functions like a sealed bathtub. soakaway problems
The consequences of soakaway problems can be severe and far-reaching, including: Nature abhors a vacuum, and it loves a water source
Soakaways, also known as soak pits or drainage pits, are a popular solution for managing surface water runoff from roofs, driveways, and other impermeable surfaces. They work by allowing water to slowly infiltrate into the ground, reducing the burden on stormwater drains and minimizing the risk of flooding. However, like any other drainage system, soakaways can experience problems that can lead to a range of issues, from waterlogging and flooding to contamination and structural damage. Once inside, they create a net that catches
A 5-year-old soakaway serving a 150m² roof began flooding the lawn after moderate rain. Water remained in the inspection chamber for 4 days.
Soakaway problems can have significant consequences, from waterlogging and flooding to contamination and structural damage. However, by understanding the common causes of soakaway problems and implementing proper design, installation, and maintenance practices, homeowners, builders, and engineers can minimize the risk of soakaway failure and ensure that these drainage systems function effectively. By following best practices for soakaway maintenance and considering alternative drainage solutions, we can reduce the risk of soakaway problems and create more sustainable and resilient drainage systems.
