Retaining wall design for residential sections, lifestyle blocks and commercial developments across Northland. Core Engineering's geotech and structural teams work together for smarter, more cost-effective solutions.
Enquire TodayRetaining structures are a critical element of any building site that requires cut or fill to create a usable building platform. Core Engineering's structural team specialises in the design of a full range of retaining solutions — from small residential walls to large commercial earth retention systems.
We design timber pole, crib block, masonry block, reinforced concrete and Mechanically Stabilised Earth (MSE) walls. Our structural engineers work closely with our geotechnical team to ensure wall designs are based on accurate soil parameters from site investigations — not generic assumptions. This integrated approach reduces risk and often results in more cost-effective designs than when geotech and structural are handled separately.
We provide full design documentation, Producer Statements (PS1) and can carry out construction inspections and issue PS4s on completion, giving you a complete, consent-ready package from one team.
Cost-effective for moderate heights. Commonly used on residential sections throughout Northland.
Precast crib and concrete block systems suited to a range of residential and commercial applications.
Cantilever and counterfort walls for higher-load applications and commercial developments.
Mechanically Stabilised Earth walls for large retaining requirements — cost-effective at scale.
Rock-filled gabion systems for erosion control and informal retaining in rural and coastal settings.
Stabilisation of steep cut faces and existing failing slopes requiring immediate engineering intervention.
Founded in Whangarei in 2020 by David Leslie, Core Engineering Solutions Limited was built around a simple idea: bring genuinely qualified, multi-discipline engineers under one roof and deliver real value to every client — not just a report, but a solution.
Our engineers hold Chartered Professional Engineer (CPEng) status — the highest professional credential in New Zealand engineering. You get qualified expertise, not junior sign-offs.
Our engineering team brings over 30 years of combined experience across civil, structural and geotechnical disciplines — spanning residential, commercial, infrastructure and rural projects throughout Northland.
Civil, structural and geotechnical under one roof. No coordinating between firms, no conflicting reports — your project is handled start to finish by a team that works together.
We focus on practical solutions that work for your project and your budget — not over-engineered complexity. Clear communication, straightforward advice, and documentation that gets your consent through.
Based in Whangarei with a Waipu office, we are a genuinely local firm — we know Northland ground conditions, councils and communities from the ground up.
