Need a retaining wall engineered in Northland? Gumboots Consulting Engineers provides retaining wall design combining geotechnical and structural engineering expertise — for building consent-compliant retaining walls in Kerikeri, Paihia, Bay of Islands, Whangarei, and across the Far North.
In New Zealand, retaining walls over 1.5m high (or any height if surcharges like vehicles or buildings apply) require building consent and an engineer's design. Northland's hilly terrain means retaining walls are one of our most common projects.
Cutting into a slope to create a flat area for a house or garage nearly always requires engineered retaining. We design the wall and provide the geotechnical report for consent.
Steep driveways in Paihia, Bay of Islands, and Kerikeri often require retaining on the cut side. Vehicle surcharge increases the engineering requirement.
Old timber or block walls that are leaning, cracking, or failing need a proper assessment before repair or replacement — to avoid rebuilding the same problem.
Retaining walls are common in subdivision development to maximise useable land area on sloping sites. We design these as part of the full subdivision engineering package.
Full structural engineering design for timber, concrete block, concrete, and steel retaining walls. We produce consent-ready drawings and calculations accepted by FNDC and WDC.
Every retaining wall design needs geotechnical parameters — soil bearing capacity, lateral earth pressures, and backfill specifications. Our geotechnical reports provide this as part of the design process.
Drainage failure is the leading cause of retaining wall collapse. We design sub-surface drainage systems behind retaining walls to manage water and extend wall life.
We prepare the full consent package for your retaining wall — engineering drawings, calculations, specifications, and producer statement — to streamline your FNDC or WDC building consent.
Based in Kerikeri, we design retaining walls throughout Northland with fast turnaround and full consent documentation. Get in touch for a quote.
