What Is A Retaining Wall?

An indispensable construction meant to “retain” or hold soil behind it is a retaining wall. These walls are an essential component of building and landscaping, particularly in areas with sloping or uneven terrain. A retaining wall is essentially a strong wall that allows soil to be held at varying levels on both sides by supporting it laterally. Let’s examine retaining walls, their functions, and typical applications in New Zealand in more detail.

Definition and Purpose

Retaining walls are a flexible solution for both residential and commercial landscapes since they fulfill several functions. Fundamentally, the purpose of a retaining wall is to stop soil erosion, which is the natural process of soil erosion brought on by wind, water, or other environmental elements. Serious problems may result from this erosion, especially in places with heavy rainfall or close to bodies of water. Retaining walls safeguard property and stabilize the landscape by keeping the soil in place.

Retaining walls are essential for controlling water flow in addition to preventing soil erosion. It takes proper water management to stop flooding and other water-related problems. Water flow can be diverted away from certain locations by designing retaining walls with drainage systems, safeguarding building foundations and lowering the possibility of water damage.

The production of usable flat space in otherwise difficult terrain is a significant function of retaining walls. Retaining walls have the ability to level down sloped areas on properties with hillsides or uneven terrain, making them suitable for parking lots, patios, gardens, and other construction projects. This raises a property’s usefulness and value in addition to improving its visual appeal.

Common Uses in New Zealand

New Zealand’s varied and frequently rough terrain makes retaining walls a prevalent feature in a variety of settings. The following are some common uses for retaining walls that are very advantageous:

1. Sloping Properties: Many properties in New Zealand are located on hillsides or have uneven ground. In such cases, retaining walls are essential for creating level areas for gardening, outdoor living spaces, or additional structures. They help maximize the usable space in properties that would otherwise be considered too steep for development.

One of the most frequent mistakes people make in construction projects is underestimating the costs involved. This doesn’t just mean the cost of materials or labor; it encompasses everything from the initial planning stages to the final touches. Many people fail to account for hidden costs such as permits, inspections, design changes, and unexpected delays. 

Why is this a problem?  

When costs are underestimated, projects often run out of money before completion, leading to either a rush to finish with subpar materials or the need to seek additional funding. This not only delays the project but can also significantly increase the final budget. It’s crucial to create a comprehensive budget that considers all aspects of the project, including a contingency fund for unforeseen expenses. Conducting thorough research, consulting with professionals, and planning for the unexpected can prevent the unpleasant surprise of a budget shortfall.

How to avoid this mistake:  

To avoid underestimating costs, start by creating a detailed list of all the materials and services required. Get multiple quotes for each to understand the price range and allow room for any price increases or extra costs. Additionally, include a contingency of about 10-20% of the total budget to cover unexpected expenses. Regularly review your budget and expenditures as the project progresses to stay on track.

2. Ignoring Local Regulations

Another common oversight in construction is failing to comply with local regulations and building codes. Every region has its own set of rules and regulations governing construction, which may include zoning laws, environmental guidelines, and safety standards. Not adhering to these regulations can result in severe penalties, including fines, forced modifications, or even demolition of the non-compliant structure.

Why is this important?  

Ignoring local regulations can halt your project in its tracks. For instance, building without the necessary permits can lead to legal trouble or safety issues that could have been avoided. The process of obtaining permits and approvals can be lengthy and complicated, but it is essential to ensure that your project meets all legal and safety requirements. Additionally, failure to comply with local regulations can have long-term consequences, such as difficulty selling the property or facing legal action.

How to avoid this mistake:  

Before starting any construction project, thoroughly research the local building codes and regulations. Contact your local council or building authority to understand the necessary permits and approvals required for your project. It is also beneficial to work with a professional who is familiar with local laws and can guide you through the permitting process. Make sure all necessary permits are in place before commencing work, and keep documentation on hand in case of inspections.

3. Poor Drainage Planning

Effective drainage is often overlooked in the planning stages, but it is one of the most critical aspects of a successful construction project. Poor drainage planning can lead to water damage, mold growth, and even structural damage over time. If water is not properly directed away from the building, it can cause foundations to shift, erode landscaping, and create a host of other problems that are costly to fix.

Why is proper drainage crucial?  

Without proper drainage, water can accumulate around the foundation, seep into basements or crawl spaces, and create a damp environment conducive to mold and mildew. This not only poses a health risk to occupants but can also lead to expensive repairs. Additionally, water pooling can damage landscaping, erode soil, and affect the stability of the structure.

How to avoid this mistake:  

Invest time in planning a robust drainage system that suits the topography of the land. Consider installing gutters, downspouts, French drains, and grading the land to direct water away from the building. Work with a qualified professional to design a drainage system that prevents water accumulation near the foundation. Regularly inspect and maintain the drainage system to ensure it remains effective over time.

Avoiding these common mistakes in construction projects can save you time, money, and a lot of headaches. By thoroughly planning your budget, ensuring compliance with local regulations, and prioritizing proper drainage, you set the foundation for a successful project. Remember, attention to detail in the early stages can prevent significant issues down the line, leading to a smooth and successful construction experience.
