Foundations Built by Keen Builders Ltd
At Keen Builders Ltd, we provide professional foundation construction for residential projects, including slab foundations and timber pile systems. A strong, well-built foundation is essential to the long-term performance of any structure, and our team has extensive hands-on experience building a wide range of foundation types.
We carry out this work in-house with our own team, ensuring quality control from the ground up and maintaining consistent standards throughout the build process.
Repiling and Structural Foundation Repairs
Older homes can often suffer from failing piles, uneven floors, or structural movement caused by age, moisture, or ground movement. Keen Builders provides repiling services to restore the structural integrity of your home.
Our team can safely lift and support existing structures while replacing damaged or deteriorated piles. This process helps level floors, strengthen the building structure, and extend the lifespan of the home.
Basement Excavation and Underground Construction
For properties where additional space is needed, we can carry out underground excavation for basement construction. This process involves carefully digging beneath or beside an existing structure to create new usable space below ground level.
Our team works through the stages of excavation, structural support, and foundation preparation to ensure the building remains stable while construction takes place. Basement construction can provide valuable extra space for storage, living areas, or utility rooms, while maintaining the footprint of the home.
Foundation Types We Build
Tiny Home Foundations
We construct foundations suitable for tiny homes that are relocated onto site, ensuring the base is level, structurally sound, and ready for installation.
Garage Slabs (Slab-on-Grade)
Concrete slab foundations are ideal for garages and outbuildings. We prepare the site, install reinforcing, and pour slabs that are durable and built for long-term performance.
Rib Raft Slabs
Rib raft foundations are a modern engineered slab system commonly used in new home construction. These foundations provide excellent strength and distribute loads evenly across the building platform.
Timber Pile Foundations
For homes requiring elevated structures, we build timber pile foundations, including piles, bearers, and joists constructed to meet New Zealand building requirements.
