Building a new home?
We work closely with builders throughout Southland and Otago to install drainage systems before foundations are poured, ensuring your project stays on schedule.
Our team coordinates with other trades to complete drainage efficiently while maintaining the highest workmanship standards.
Stormwater & Surface Water Drainage
Southland weather can bring heavy rainfall, making effective stormwater drainage essential. We install drainage systems designed to move water safely away from your home, helping reduce the risk of flooding, erosion and water damage. Proper stormwater management also helps protect driveways, landscaping and building foundations.

Septic Tank & Rural Drainage
Many rural properties rely on septic systems and effluent disposal.
We install drainage solutions that provide reliable wastewater management while meeting environmental and council requirements. Whether you're building a lifestyle block or upgrading an existing system, we can recommend the right drainage solution for your property.

Drain Repairs & Upgrades
Older drainage systems can become damaged by tree roots, ground movement or age.
If you're experiencing slow drainage, recurring blockages or damaged pipes, we can assess your drainage system and recommend the most cost-effective repair or replacement option.
Replacing ageing drains can help prevent expensive emergency repairs in the future.
