Types of services that house lifters and piling specialists provide in New Zealand

House lifting 

House lifting involves raising and elevating existing homes to repair foundations, prevent flood damage, create basement space, or elevate structures according to regulatory requirements. House lifting contractors use hydraulic jacks, airbags, cribbing towers, and other specialised equipment to slowly lift a home off its foundations. They detach any additions like porches or garages and may temporarily detach utilities before the lift. Once raised, the existing foundations can be repaired or replaced. The home is then lowered onto a new or refurbished foundation and reconnected to any additions and utilities.

Piling and foundation work 

Piling and deep foundation contractors in New Zealand install load-bearing piles, piers, caissons, or helical screws to provide structural support and stability. Common pile types include wooden piles, steel beams, precast concrete, and helical screws. Contractors conduct soil tests and analyses to determine the appropriate piles and capacities required. Piles are driven into the ground or excavated shafts are drilled, then filled with concrete or rebar cages. Contractors sometimes load test sample piles to validate capacity. Deep foundation elements like piles secure the structure against settling or shifting and transfer weight through unstable soil to load-bearing strata.

Site preparation and excavation 

Prior to major foundation work, contractors first prepare the site which may include demolishing existing structures or land clearing. They conduct surveys to mark utilities and property boundaries. Excavation equipment is brought in for digging, trenching, grading, or soil removal to reach the desired elevation and contours. Soil testing helps determine the appropriate ground improvement techniques like compaction, injection, or reinforcement. During foundation construction, contractors implement erosion control measures to reduce environmental impacts. They will often work with earthworks contractors during this process. 

Underpinning and foundation strengthening

Underpinning refers to reinforcing and stabilising existing foundations by installing supplemental supports. Common underpinning methods include new pilings installed next to sagging foundation walls and steel beams added under concrete floor slabs. Contractors may also inject structural epoxy resins into cracked foundation elements or deteriorating masonry and concrete. Damaged sections get rebuilt while adjacent areas are shored up temporarily. Underpinning helps level settled structures, provides additional load-bearing capacity, and better integrates additions with existing construction. This may also involve the expertise of foundation specialists.

The advantages of hiring an experienced house lifter and piling specialist

Hiring an experienced house lifting and piling contractor in New Zealand has four key advantages over doing the work yourself or hiring a general contractor. First, specialists have the specialised equipment these projects require, like hydraulic jacks and pile rigs. Second, they have the technical expertise that comes from advanced training and working on myriad foundation projects. Mistakes in determining methods or capacities can prove disastrous. Third, specialists follow strict safety protocols when executing high-risk techniques like lifting homes or pile driving. Finally, they develop optimised plans to efficiently modernise foundations within time and budget constraints. The wrong approach often leads to delays and cost overruns.

How to choose the best house lifter and piling specialist for your project

When selecting the best house lifter and piling specialist for your project in New Zealand, a thorough evaluation is essential. Begin by assessing their relevant experience to ensure they have successfully managed projects akin to yours. Verify their licensing and credentials, confirming professionalism and compliance with local standards. It's critical for a specialist to conduct a detailed, first-hand assessment of your site, enabling accurate planning and anticipation of potential challenges. Discussing their health and safety procedures and methodologies in depth is vital for the project's safety and success. Additionally, ensure they have access to all necessary specialised equipment, crucial for efficient and effective work. Review client references and past work to gain insights into their work quality, reliability, adherence to schedules, and budget management. Lastly, confirming comprehensive insurance coverage, including liability and worker's compensation, is important for financial protection against potential issues or accidents during the project.
