Drainage problems are common on lifestyle blocks, especially where clay subsoils, springs, or altered landforms redirect surface water. Spotting issues early can save thousands.
Warning signs
- **Persistent wet patches** in paddocks or near buildings, especially after rain
- **Water pooling against foundations, tracks, or fence lines**
- **Erosion or gullying** on slopes or tracks
- **Spongy or boggy ground** that does not dry out between rain events
- **Cracking or movement** in building foundations, drives, or paths near wet areas
Common causes
- Blocked or collapsed field tiles or cut-off drains
- Springs or seeps activated by heavy rain or earthworks
- Changed runoff patterns after land clearing or building work
- Inadequate or missing surface drains on hill properties
- Compacted soil in stock races or gateways
What you can do
- Walk the property after heavy rain and note where water ponds or flows.
- Keep existing drains and culverts clear of debris.
- Avoid building or planting over known drain lines.
- If you are planning earthworks, talk to a drainage or earthworks contractor about managing runoff.
When to call a professional
- You see persistent wet ground near buildings or infrastructure
- A track or driveway is washing out
- Water is entering a building or shed
- You are planning land clearing or earthworks and need drainage advice
- Existing drains are not coping with runoff
Questions to ask a drainage contractor
- What size machinery do you operate, and will it suit my access?
- Do you handle drainage as well as earthworks?
- Can you advise on council consent for drainage works?
- What is your minimum charge-out or mobilisation fee?
- Do you provide a written quote?
