Drain Repair · Part 2 — Preparing the drain repair
By Greg the Geeza · 9 October 2026
After the rain came the repair job. Soil washed away from behind our retaining wall, so now we need to sort out the drainage before replacing it.
Sorting out the next step
The last update showed the damage. This one is about tackling the drainage and preparing to put geotextile in place, rather than just replacing the lost soil and hoping for the best.
I’ve bought the 150 g/m² geotextile for the job. The aim is to help keep the soil separate from the drainage material while allowing water through.
One job at a time
It’s another job on the list before we can get back to the rest of the garden. We’re working through it with the budget we’ve got, and I’ll share how it goes as the repair progresses.
This is an update on our own project, rather than a finished how-to. We’ll see how the repair holds up when the rain returns.
