Bentonite clay is a versatile substance employed for ages to seal and waterproof a wide range of constructions. Today, it is still a well-liked option for homeowners seeking to prevent water damage to their foundation walls. Applying bentonite clay to the exterior of the foundation forms a barrier that keeps water from penetrating. It provides various upsides, including simplicity of application and durability, but certain drawbacks must also be considered. In this article, you can find out about using bentonite against a foundation wall, its details, and the pros and cons of the process so that you can decide if this technique is appropriate for your project.
What is Bentonite Waterproofing?
Using bentonite against a foundation wall is a type of waterproofing using bentonite clay as the crucial substance. To learn more about this process, its advantages and disadvantages, and its alternatives, it is vital to find out about bentonite clay and waterproofing using this clay.
Bentonite clay is a naturally occurring substance made of volcanic ash, renowned for its distinct qualities. It works well as a waterproofing material since it may expand up to many times its original size when exposed to water. There are several types of bentonite clay, including calcium and sodium bentonite. The most used bentonite for waterproofing is sodium bentonite, which has a high swelling capacity and can swell up to 15 times its original volume when in contact with water. Waterproofing can also be accomplished with calcium bentonite; however, this material is more frequently employed in industrial settings and has a lesser swelling capacity than sodium bentonite.
Bentonite waterproofing is a standard approach for preventing water intrusion in various spots, including basements and foundation walls. Bentonite is commonly used as a waterproofing membrane, which entails covering the surface of the wall or basement floor with a layer of bentonite clay. Bentonite reacts with water to create a gel-like substance that seals the surface and keeps water from permeating it. Because it is a natural, non-toxic substance that does not deteriorate with time, bentonite waterproofing is a popular option for avoiding water penetration in structures. Yet, the success of bentonite waterproofing is dependent on correct installation and preparation.
Using Bentonite Against a Foundation Wall; How Does It Work?
When put against a foundation wall, bentonite can be a very efficient waterproofing substance. Using this method, a coating of bentonite clay is applied to the exterior of the foundation; the clay expands to form a barrier that keeps water from entering the wall when it comes into touch with moisture. The bentonite layer is frequently coated with a protective layer of soil or other materials and is typically placed on the foundation in thin sheets or by spraying. This technique is commonly employed in both residential and commercial construction, and it is particularly successful in preventing water infiltration in below-grade structures like basements.
The foundation wall must be cleaned and ready before applying bentonite for waterproofing. The surface should be clean, smooth, and free of any irregularities after debris or loose material has been cleared. Following the preparation of the wall, a coating of bentonite is usually sprayed using a spray or trowel. The clay is frequently combined with water to create a slurry that can quickly be put to the wall. As the bentonite dries, it solidifies into a coating that sticks to the wall’s surface and creates an airtight seal.
The Advantages and Disadvantages of Using Bentonite Against a Foundation Wall
Bentonite can aid in preventing water infiltration and safeguarding the building foundation from moisture damage by establishing a barrier between wet soil and the foundation. This method turned out to be a famous way of waterproofing due to its various advantages. They include its capacity to form a watertight seal and its inherent healing qualities. However, as with any waterproofing solution, there are drawbacks to using bentonite against a foundation wall, such as its sensitivity to temperature and moisture and the necessity for excavation during installation. To decide if bentonite is the best option for your particular foundation and waterproofing needs, it’s crucial to consider these considerations and speak with an expert thoroughly.

The Pros of Using Bentonite Against a Foundation Wall
One of bentonite’s main advantages is the high impermeable qualities of clay, which enable it to establish a barrier against water infiltration effectively. Furthermore, bentonite is an excellent choice for difficult waterproofing situations since it can tolerate hydrostatic pressure up to seven levels of atm. The clay’s capacity for self-healing is another benefit of employing it for waterproofing foundations. Bentonite expands significantly in volume when moistened in a small area, efficiently filling any fractures or gaps in the foundation. The waterproofing barrier will remain intact even if little fractures appear over time because the bentonite will expand to fill them.
Additionally, using bentonite against a foundation wall is renowned for its long-lasting effects due to its consistent material qualities. The clay is a durable alternative to conventional waterproofing techniques that can weaken or deteriorate over time. Last but not least, compared to traditional waterproofing methods, installing bentonite waterproofing is easy and quick and requires little work and specialist knowledge. Bentonite is an affordable and efficient approach for waterproofing foundations since it requires only 20% as much installation work as conventional techniques.
The Cons of Using Bentonite Against a Foundation Wall
Bentonite waterproofing has its own restrictions and drawbacks that you should consider before using this method. One of the major disadvantages of utilizing bentonite on a foundation wall is incomplete coverage. Groundwater can enter the basement through overlooked areas, tiny cracks, or insufficient coverage during application. It is especially true when bentonite is administered as an injection into the soil instead of a sheet application. As a result, it’s critical to ensure the application is done precisely to block water incursion effectively. The need for outside excavation is another disadvantage of bentonite waterproofing. Your foundation must be excavated entirely before applying bentonite for complete coverage. It requires bringing heavy equipment into your property that can damage your lawn and landscaping and turn it into a large construction site. So, Avoiding damaging the foundation throughout the excavation procedure is critical.
Finally, applying bentonite to foundation walls will not prevent water from entering your basement through the specific leak point: the crack between the concrete slab floor and the basement wall. When it’s rainy outside, water can readily be forced through basement floor cracks and along the floor-to-wall junction by high hydrostatic pressure. In this case, interior drain and sump pump systems may provide better waterproofing protection since they reduce water pressure rather than increase it. As a result, it is critical to explore various waterproofing measures in addition to bentonite to offer an entire defense against water penetration.
