French Drain Solutions in Shellharbour for Effective Runoff Management

Addressing Water Ingress Challenges in Shellharbour

A homeowner in Shellharbour experienced a severe and worsening problem with water ingress. Rainwater from two neighbouring properties, which are positioned at a higher elevation, started to flow into the yard and seep beneath the foundation of the house. This unwelcome influx caused damage to the flooring, promoted rising damp, and resulted in mould growth within the property, jeopardising the integrity of recent renovations.

What Signs Indicate the Source of Water Ingress?

The issue originated from both surface runoff and subterranean water flowing downhill from the rear and side yards of adjacent properties. Without a proper drainage system to intercept this water flow, it was forced to accumulate beneath the house.

Implementing an Effective Drainage Solution

CS Plumbing engineered and installed a gravity-fed French drain system specifically designed to collect and redirect water before it could reach the foundation of the home.

The project comprised several crucial elements:

A meticulously designed French drain system to gather surface and subsurface water from neighbouring properties, channeling it through gravity to a concrete pit.
A 100mm PVC pipe extending from the pit to the curb, featuring strategically placed drilled holes in the curb to guarantee efficient water discharge.
Three newly installed, larger-diameter Colorbond metal downpipes to replace the original smaller pipes, connected to new 100mm PVC piping that leads to the curb.
A retaining wall system constructed along the boundary, employing concrete sleepers and galvanised steel posts, with auger holes drilled using an excavator to create a robust barrier that holds back the adjacent yard.
Efficient on-site soil removal, facilitated by a dumper for streamlined site management.

What Measures Should You Take for Efficient Water Management?

The newly installed drainage system now effectively captures both surface and subsurface water at the property boundary, ensuring that it is redirected away from the home. This solution provides the homeowner with a durable, low-maintenance option that protects their foundation, flooring, and the investments made in renovations.
