Yes, even very shallow timber walls require an effective drainage system. Without this, water could build up behind the wall, creating pressure and eventually leading to the wall leaning or collapsing. Poor drainage is the most common cause of retaining wall failure. Proper drainage, using gravel backfill, perforated pipes, and geotextile fabric, helps relieve water pressure and extend the wall's lifespan.

Using treated wood for your retaining wall can help ensure its resistance to rot and pests. A suitable weather-resistant finish can further enhance durability.

With quality, treated timber and proper installation—including drainage—timber retaining walls can last 10 to 25 years, or even longer. Regular maintenance like resealing and inspection can extend their lifespan.

You generally don’t need a building consent if the wall retains no more than 1.5 m of ground, supports no extra loads (like driveways or buildings), and includes suitable drainage. However, if the wall is taller than 1.5 m, supports additional loads, or is near significant features, you will need consent. Auckland Council provides an online tool to help you check whether you need a building or resource consent.

We guide you through consent, design, and construction, tailored to Auckland’s council requirements. We ensure long-term stability with correct drainage, engineered supports, and local code compliance. We draw on deep familiarity with Auckland soils, slopes, and council standards, delivering durable, compliant, and aesthetically pleasing results.
