Signs you have a drainage problem in Woolston
Drainage faults rarely announce themselves. These are the ones worth calling about before they turn into a dig.
- Spouting sagging or overflowing Leaking at the joins, or spilling over in heavy rain.
- Water running down the house Instead of into a downpipe, or pooling at the foundations.
- Slow or backing-up gully trap Especially after a downpour.
- A blockage that keeps coming back Clears, then returns a few months later.
Any of these are worth a look. Call us on 03 379 0711 and we will CCTV the line before quoting anything.
What the ground is like in Woolston
Woolston is one of the more straightforward suburbs in Christchurch to dig in, which keeps the cost of most drainage work down.
The ground here is flat and easy to dig. That sounds like a small thing, but it is the single biggest factor in what a drainage job costs. The same work on a Mount Pleasant or Redcliffs hillside takes longer, needs more care with backfill, and often means getting through rock first. In Woolston we can usually get in, do the work and get out in a fraction of the time.
The garage stormwater problem
A lot of Woolston garages were built with no stormwater connection at all, just a soak hole. That works until it does not. A soak hole relies on the ground absorbing the water, and when the volume is too high or the ground is already saturated, it backs up and you get water where you do not want it. If you are not sure which your place has, it is worth finding out before a heavy rain event tells you.
Old clay and the earthquakes
Old clay drainage is common across Woolston, and a lot of it sat through the earthquakes. Some of it was assessed and repaired afterwards. Some of it was missed, and the damage is still down there working away quietly. A drain that is slow now may have been slowly failing since 2011 without anyone looking at it.
It is worth having checked, particularly if you have never had the drains inspected and you have noticed anything gradually getting worse. We CCTV the line so you can see exactly what is there rather than guessing.

Underground
What is probably under your Woolston property
Drainage is the one part of a house nobody ever sees. Here is what we usually find under Woolston properties, and what it means.
-
Older house
Old clay drainage, laid in short lengths A lot of joins, and some may still carry unrepaired earthquake damage.
-
The garage
Often a soak hole rather than a stormwater connection Fine until the ground is saturated, then it backs up.
-
Work since 2011
PVC where sections were replaced after the earthquakes Repaired runs sit alongside original clay, so faults cluster at the joins.
-
Timber floors
Accessible connections under the house Alterations and inspections are easier and cheaper than on a concrete slab.
Our process
How we find the problem before we dig
Digging blind is expensive. We work out exactly what is wrong and where it sits, then quote the fix.
Check above ground first
In Aranui a surprising number of drainage complaints start with worn spouting or downpipes. We look there before assuming the problem is buried.
CCTV the line
If it is underground, we run a camera through the drain and see exactly what is happening and where it sits. No guesswork and no exploratory digging.
Quote the real fix
Once we know what is going on we quote it properly. On flat ground most Aranui alterations come in quicker and cheaper than people expect.

Stormwater unblocked on Maunsell Street
Cleared a blocked stormwater system at an engineering business on Maunsell Street. We handle commercial drainage as well as residential, and the same CCTV and water blasting gear comes out either way.
Ben leads our drainage work and knows the area well. We send whoever is closest and best suited on the day though, so you are not waiting on one person.

Frequently Asked Questions
Woolston drainage questions
Does my Woolston garage have stormwater connected, or just a soak hole?
A good number of Woolston garages were built with just a soak hole rather than a stormwater connection. If you are not sure which you have, we can check it as part of any drainlaying job, and it is worth knowing before a heavy rain event finds out for you.
Could my drains still have earthquake damage nobody has looked at?
It is possible. Old clay drainage is common in Woolston and some of it was missed during damage assessments after the earthquakes. A drain that has got gradually slower over the years may have been failing since 2011. A CCTV inspection shows you exactly what is there.
Why is drainage work cheaper in Woolston than on the hill?
Flat ground and easy digging. The same job in Mount Pleasant or Redcliffs means getting through rock and packing proper backfill to hold the pipe on a slope. In Woolston there is less of both, so most jobs take less time.
My soak hole keeps backing up. Can it be connected to stormwater?
Usually yes, depending on what is available at the property and where the connection point sits. We would look at it on site and quote the work, including whether council consent is needed for the alteration.
