2023 NZ Storms Expose Weaknesses in Home Foundations

New Zealand has always been a beautiful country, with scenic landscapes and a thriving economy. However, the country has also had to face several natural disasters, with the recent 2023 storms being the latest example. These storms have caused significant damage to properties across the country, and many homeowners are now realising that their homes’ foundations were not as strong as they thought.

In this article, we will discuss the impact of the 2023 storms on home foundations in New Zealand and what homeowners can do to ensure their homes are safe and secure.

The Impact of the 2023 Storms on Home Foundations

The 2023 storms that hit New Zealand were among the worst in the country’s history. The heavy rains, strong winds, and flooding that accompanied the storms caused significant damage to homes and properties across the country. The impact on home foundations, in particular, was significant, with many homes suffering from foundation damage due to the storms.

One of the primary reasons for the foundation damage caused by the storms was the soil. New Zealand’s soil is naturally soft and prone to erosion, and the heavy rains caused the soil to become saturated and unstable. This instability resulted in homes with weak foundations sinking and shifting, causing structural damage.

In addition to soil instability, the storms also caused damage to homes’ drainage systems. Blocked or damaged drainage systems can cause water to pool around the foundation, leading to further erosion and weakening of the foundation. Water can also seep into the foundation, causing it to become weaker and more susceptible to damage.

According to reports from various construction and repair companies, the number of inquiries for foundation repairs has increased significantly in the aftermath of the storms. This suggests that a large number of homes have been impacted, with homeowners seeking solutions for their damaged foundations.

It is important to note that the impact of the storms varied depending on the location of the property, the type of soil, and the quality of the construction. Properties located in areas prone to flooding or erosion were at a higher risk of foundation damage, as the soil around the foundation can become unstable due to excessive water exposure. Similarly, properties built on poor-quality soil, such as clay or sand, were more susceptible to foundation issues.

While it is difficult to determine the exact percentage of homes with damaged foundations, it is estimated that a significant number of homes have been affected by the storms.

If you suspect that your home’s foundation has been damaged by the storms, it is essential to seek professional help immediately.

Level Up: The Importance of Residential Foundation Relevelling

Why is it important? Well, when your foundation is uneven or sinking, it can cause structural damage to your home. Doors and windows may not open or close properly, walls may crack, and floors may warp. In addition, an uneven foundation can cause water to pool around the house, leading to moisture problems and potential mould growth.

Furthermore, a damaged foundation can have serious implications on your home’s resale value. Prospective buyers are likely to have the property inspected before making a purchase, and a faulty foundation can be a major red flag.

Residential foundation revelling is not a DIY project, and it’s not something you should entrust to just any contractor. It requires a team of experienced professionals who have the necessary equipment, skills, and knowledge to get the job done right.

Sinking Feeling? Here’s What to Do When Your Piles Have Sunken

Discovering that the piles supporting your home or building have sunk can be a sinking feeling indeed. Not only can it cause cosmetic issues, such as cracks in walls and uneven floors, but it can also put the structural integrity of the building at risk. However, it is essential to know that sinking piles can be fixed.

The first step is to identify the cause of the sinking. Common causes include poor soil conditions, water damage, and improper installation. Once the cause is determined, a solution can be implemented. This could involve underpinning, which is the process of installing additional support beneath the existing foundation, or pile replacement.

Underpinning involves installing piers or beams beneath the existing foundation to provide additional support. This can be done using a variety of techniques, such as helical piers, push piers, or micro-piles, depending on the specific conditions of the site. Pile replacement, on the other hand, involves removing the existing piles and replacing them with new ones.

It is crucial to work with a reputable and experienced contractor for pile sinking issues. CCS can provide an accurate assessment of the situation and recommend the most appropriate solution for the specific conditions of the site. Ignoring the problem can lead to more significant structural issues and potential safety hazards so don’t delay if this is an issue your property is having.

The Hidden Danger Under Your Home: Void Filling Solutions

Void filling is a crucial process in the construction and maintenance of homes. Essentially, voids are empty spaces that exist beneath a structure’s foundation, which can cause significant problems. The number of homes experiencing this issue after the storms earlier this year is huge, with one of the most common issues being voids created underneath the foundation.

When left unaddressed, voids can cause damage to your home’s foundation, leading to expensive repairs and a decrease in your property’s value.

Another method for addressing voids is through the use of grout injection. Grout is a mixture of cement, water, and sand that is pumped into the voids under your home. This material is also highly effective in filling the gaps and creating a stable foundation.

It is important to note that void filling should be done by a professional. A trained technician can identify the root cause of the voids and choose the appropriate solution to address the problem. By investing in void filling, you can ensure the longevity and stability of your home’s foundation, and avoid costly repairs down the line.


In conclusion, the 2023 storms in New Zealand have exposed the weaknesses in home foundations and highlighted the importance of regular inspections, maintenance, and repairs to prevent costly damages. Void filling solutions and foundation revelling can provide effective solutions for homeowners facing sinking or damaged piles, or voids under their homes.

It is essential to seek the assistance of a reputable and experienced contractor, such as CCS, to ensure that the job is done correctly and safely. Neglecting foundation repairs can lead to a variety of serious problems, including structural damage, water infiltration, and even health hazards. Homeowners should prioritise maintaining the structural integrity of their homes and seek professional help at the first signs of any issues with their foundations.

By taking proactive measures and working with trusted professionals, homeowners can protect their investments and ensure that their homes are safe, secure, and comfortable places to live.
