complex foundations
At A-Class Builders, we thrive on the projects that others shy away from. Our experience includes a wide range of challenging foundation systems, from steep sites and multi-level concrete foundations to complex excavations and structural retaining solutions.
One of our most challenging projects involved constructing a three-storey split-level home with multiple concrete and blockwork foundation levels on a difficult sloping site. The project required careful coordination, precise set-out, and strict quality control to ensure every stage was completed to engineering specifications.
Our Simple 4-Step Method
01
Plan and Consult
We thoroughly review your plans to ensure they meet New Zealand Building Code requirements and consented documentation. By identifying potential issues early, we create a clear roadmap for a smooth and stress-free construction process."
02
Groundwork and Prep
After excavation is completed, we carefully check site levels, dimensions, and ground conditions against the approved plans. Our detailed QA checklists ensure everything is correct before foundation work begins.
03
Steel and Concrete
We install the foundation boxing, DPM, and reinforcing steel to the highest standard, followed by a detailed QA inspection before concrete placement. Our thorough process ensures a strong, durable foundation built to last."
04
Sign-off and Handover
We perform a thorough quality check to confirm everything is perfect before you move to framing. You receive a solid foundation and total confidence for the next phase.
