Repiling Christchurch Homes
Repiling a house in Christchurch is a common earthquake-related foundation repair. The process is reasonably simple, but it does mean that your house will be out of action for approximately 2-4 weeks. Firstly, all of the floor coverings need to be removed, including carpets and underlays, and then we'll secure the house structure in place to control stability and relevel the floor if required. Once completed, we'll install new piles as per the engineering designs.
House Repiling & Insurance
House repiling doesn't have to be earthquake-related; it can simply have deteriorated over time. Insurance companies often make this a requirement to reinsure the house if you are looking at buying an existing home. In some areas, it's a mandatory requirement by insurance companies to have your foundations upgraded - restrengthened, especially in earthquake-prone areas, such as Christchurch & Wellington.
Repiling A House
Old-style piles were made from concrete, and over time, or if the house moves, these tend to deteriorate and crumble. Nowadays, repiling a house occurs with new-style piles that are made from treated timber that is load-tested and designed to last at least 100 years. Wrightway only uses the latest technology, ensuring your home will remain stable and can endure nature's unpredictable surprises as best as possible.
The House Repiling Process
Connect With Us
Initially, customers usually email or call about repiling Christchurch homes. We’ll set a time for our senior-level staff to visit and undergo a free inspection of everything related to repiling a house.
Structural Engineering Design
First, we’ll need to obtain a structural engineering design, drawn up for the piles that require replacement during your house repiling project.
We then need to apply for consent after the structural design. This can take 2-4 weeks for the design, and then exemption consent can take 1-2 weeks.
Once consent has been approved, we start the construction phase of house repiling. Works can take up to 4 weeks, depending on the size of the project.
When repiling a house, you’ll need to find alternative accommodation during this period, and if this is an earthquake or insurance-related requirement. You’ll find that this may be paid for in your claim.
Once the process is finished, you’ll be walked through your property with a level tool, and explained how the house repiling process went. We’ll ask you to measure and sign-off that you’re 100% happy with our workmanship.
Frequently Asked Questions
Repiling a house is reestablishing the foundation of the house. It's reconnecting the house to the bearer to the pile, to the ground.
The cost to repile a home in New Zealand is approximately $350 per pile. This includes the excavation for the pile, the installation of the pile and the connections from the pile to the bearer.
You may notice loose or damaged piles, even piles that are cracked or leaning. We use a zip level to take the levels of the floor; we set the datum level to zero, and then we check each room, usually one in the middle of the room and one in each corner of the room. If there are levels higher or lower than the MBIE guidelines. If the levels were outside of tolerance, then we would carry out a sub floor inspection to understand exactly what is happening and what the next action is. Jacking and packing the piles may be the option, or re piling may be required.
You may notice loose or damaged piles, even piles that are cracked or leaning. We dig out the foundation for the pile; we pour concrete and we put the pile in place, ensuring a minimum of 100mm of concrete is below the pile and on top of the ground, and then pour concrete around the base of the pile ensuring it is plum. We then connect to the bearer. You need to be, or be supervised by a licensed building practitioner.
