Drainage and Moisture Control in Kyle Bay
This customer in Kyle Bay called us about a chronically wet concrete slab along the side of their house. This was causing a significant mould problem inside their home and bedrooms as well as making their carpets wet. In addition to this, there were also some underlying issues with the existing stormwater and sewer systems, including blockages, poor pipework and tree root intrusion.
For this project, our team used excavation, drainage and moisture control techniques to protect this home's concrete slab and walls from long-term water damage.
Why Does This Happen?
This type of drainage issue is common in Sydney properties that are built on dense clay soils. Clay naturally holds onto water rather than letting it drain away. When combined with a poorly designed drainage system or old infrastructure, excess water becomes trapped in and around the building.
How We Diagnosed It
Our plumbers assessed the water flow, checked the performance of the drains and identified faults in the existing system.
On jobs like these, we typically use CCTV Drain Inspection techniques and testing to locate blockages, tree root intrusion and structural pipe issues.
Our Drainage Strategy
Our strategy was to install a subsoil and surface drain at the back and western side of the home to prevent further damage to the structural integrity of this Kyle Bay property.
This system was designed to:
- Move water away from the foundation quickly
- Allow the concrete slab and walls to breathe and stay dry
- Prevent excess water damage and stagnation during heavy rain and storms
- Separate the stormwater and subsoil drainage systems
Our Work
This drainage project in Kyle Bay included:
- Excavating trenches and removing the dense clay soil
- Installing a breathable drainage cell against the walls and slabs of the home to allow for airflow
- Installing a subsoil drainage system (aggi drain, syphonic pipe system) and a dedicated PVC line for new surface drains
- Backfilling the trenches with a mixture of sand and gravel for fast-acting drainage
- Repairing stormwater and sewer issues, including root removal
- Removed troublesome tree and replaced pavers with concrete paths to reduce water penetration
The Results
This new drainage system keeps this Kyle Bay home safe and dry, effectively draining away surface water while preventing future blockages from occurring.
