A retaining wall is crucial to properties on sloped landscapes. These structures support the soil laterally and safeguard it against erosion and instability, both significant threats to the building.
While retaining walls can help protect your residential property, you also need to keep these walls safe from harmful elements to maintain their integrity and functionality. That is why waterproofing retaining walls is essential.
To help you understand how retaining walls work, read this blog, where we’ve outlined a comprehensive guide.
Understanding the Importance of Waterproofing
The primary function of a retaining wall is to hold back soil, which inherently contains moisture. Over time, this moisture may seep into the wall, causing damage like cracks and leaks, eventually leading the walls to collapse.
Therefore, waterproofing these walls is not just a preventative measure but a necessary step to ensure the longevity and functionality of the wall. Here are other reasons why you need retaining wall waterproofing:
Stability Enhancement
In the world we live in, the weather can change from time to time. You can’t expect the days to always be sunny. That is why you must prepare for rainy days and ensure that your property stands still despite the changing environment and water pressure.
Remember, water can exert pressure on the retaining walls, especially during heavy rainfall or in areas with high groundwater levels. Waterproofing reduces the risk of water pressure buildup, protecting the wall’s stability.
Longevity
The best retaining wall waterproofing helps prolong the life of a retaining wall by preventing damage caused by water or moisture. Think of it as a shield for the retaining wall. Without waterproofing, water can seep into the wall’s materials, causing damage over time.
Reducing Maintenance Needs
When water pressure compromises your retaining wall’s structural integrity, you will pay high repair or restructuring costs. As such, waterproofing these walls guarantees they can withstand environmental factors and remain strong without much maintenance.
Moreover, retaining walls must be properly constructed and waterproofed to prevent soil collapse or sudden land movements. Remember, it is imperative for the safety of the property’s occupants.
Aesthetic Preservation
Aside from its practical benefits, concrete retaining wall waterproofing or waterproofing your retaining walls also helps with its aesthetic preservation. Waterproofed surfaces prevent moss growth, allowing you to maintain these walls’ look.
Several waterproofing materials also come in various finishes or colours, contributing to the overall aesthetics of the retaining wall while providing protection against water damage.
Crucial Steps to Waterproofing Retaining Walls
The process of retaining wall waterproofing may vary from one service provider to another. The wall’s current condition and climate may also affect the waterproofing procedure.
Regardless, effective waterproofing isn’t just about applying a protective layer on the wall’s surface. It involves a series of steps to ensure the retaining wall’s protection.
These steps include the following:
1. Inspect and Prepare the Wall
Before doing anything else, inspecting the retaining wall for any cracks or damage is essential. Also, remove any debris, dirt, or loose material from the wall. This step may involve brushing, washing, and possibly sandblasting for thorough cleaning.
If the wall has any cracks or gaps, make sure to fill these and repair any existing damages.
2. Apply Waterproofing Membrane
For this step, remember that it is crucial that you choose the right waterproofing retaining walls products. Different types of waterproofing membranes are available in the stores, including liquid membranes, sheet membranes, and cementitious coatings. Liquid membranes are popular because they’re easier to apply.
Always follow the manufacturer’s instructions if you decide to do the project and apply the membrane yourself. You will usually need a brush, roller, or sprayer for this process.
3. Optional Steps
There are two optional steps after applying the waterproofing membrane:
1. Coating: In some cases, you can apply a waterproof coating or sealant over the membrane for additional protection.
2. Insulation: You may also add insulating materials for thermal protection. This step is beneficial for properties settled in colder climates.
4. Regular Maintenance
After the application, inspect the wall to ensure complete coverage.
Additionally, you must note that the tasks don’t end there. To avoid water accumulation and the rising retaining wall waterproofing cost for repairs, ensure that your property has drainage systems. You must also regularly inspect the wall and surrounding area for signs of water pooling or leaks.
Tips from a Waterproofing Professional
1. Consider Proper Drainage
According to a waterproofing expert, a properly installed drainage system is crucial for preventing water buildup behind the retaining wall. This reduces hydrostatic pressure, which can otherwise push against the wall and cause structural issues.
You may install drainage systems like weep holes, gravel backfill, or French drains to manage water flow and reduce pressure efficiently. However, you must consider the space available and the proper placement of the system.
2. Use Climate-Appropriate Materials
As previously mentioned, you need to choose the right materials for your project—and one of the factors you need to consider when purchasing materials is the climate of the place your property is in.
Choose materials with the ability to withstand temperature changes and specific moisture conditions.
If you’re unsure which ones will work best in your area, it is best to consult a professional to not waste your money.
3. Invest in High-Quality Materials
In relation to the tip mentioned above, you must also invest in high-quality waterproofing retaining walls products for your waterproofing project. Trying to cut costs on materials can compromise the effectiveness of the waterproofing. If you do so, you’ll only end up paying more because your walls will be prone to damage.
4. Inspect the Walls Regularly
Bear in mind that perioding inspections are still crucial, even with waterproofing. So, check for any signs of water seepage, cracks, or damage.
Addressing issues earlier can prevent minor problems from escalating into more significant concerns. Routine maintenance, such as cleaning drainage systems and repairing damaged waterproofing materials, helps maintain the wall’s integrity over time.
5. Consult a Professional
While some DIY waterproofing solutions exist, hiring waterproofing experts ensures proper installation and effectiveness. These professional waterproofing specialists have the experience and knowledge to assess the unique needs of your retaining wall, select the right materials, and execute the waterproofing process correctly.
More importantly, these experts help you save time, minimise errors, and ensure long-term protection for the wall.
