Drainspec is a family-run drainlaying business based in Whangarei, providing drainage, septic and water tank services to homeowners, builders, lifestyle block owners and bach owners right across Northland. With more than 25 years in the trade, the team knows how local conditions affect a drainage job, from heavy clay soils and sloping sections to the different requirements of Northland’s councils, and every job is planned with those in mind.
Whether you’re building a new home, replacing an old septic tank, setting up a water supply on a rural block or dealing with a wet section, Drainspec can take care of it. Because they cover drainage, septic systems, water tanks, pumps and waterproofing, most property owners can get their drainage and water systems sorted with one local team, rather than coordinating several different trades.
Drainage
Drainspec lays new build drainage, extensions and repairs for residential properties, along with stormwater systems that move water safely away from homes and driveways. Subsoil drainage helps with wet sections, soggy lawns and water sitting against retaining walls or foundations. They also clear and repair blocked drains.
Septic Tanks and Wastewater
For properties not connected to town sewerage, Drainspec supplies and installs new and replacement septic systems, including concrete septic tanks and secondary treatment systems. As a certified Hynds and Duracrete installer, they fit tanks and treatment systems to the manufacturer’s requirements, sourcing from Northland suppliers Duracrete and Wade. They also design septic solutions for baches and holiday homes, where use is occasional and sites can be harder to reach, a speciality many drainlayers don’t offer.
Water Tanks and Pumps
Drainspec supplies and installs concrete and poly water tanks, taking care of everything from preparing the pad through to connecting the supply to the house. They also supply, install and replace water pumps and septic pumps.
Basement Waterproofing
Damp basement walls are a common problem on Northland’s sloping sites. Drainspec carries out exterior basement waterproofing combined with the drainage needed to keep water away from the wall long term.
Quotes and Service
Every job is quoted individually at a fixed price, and quotes are free in Whangarei and the surrounding area. For remote properties, a drainage report ($499 + GST) sets out what work is needed before a special trip is made. Drainspec replies to every enquiry within one working day, and if there is ever a problem with their work, they’ll come back and put it right.
