Looking to protect your home or commercial building against water leaks or flooding issues, there are two main waterproofing methods. They are known as bentonite and injection waterproofing. While both of these methods are similar in many ways, they have some distinct differences.

Let’s break into the benefits of each of these waterproofing methods.

Bentonite Waterproofing

Bentonite clay is a type of waterproofing clay that is used with different materials to create a waterproofing membrane around the foundation of buildings. Sodium bentonite—the element found in bentonite clay that absorbs water—is capable of expanding 15x it’s regular volume as it comes in contact with water. Each pound of bentonite clay can absorb up to two gallons of water.

Waterproofing with clay has long been a popular practice, as it was one of the first known methods for waterproofing homes. Today bentonite clay waterproofing has become an industry standard. Sodium bentonite and bentonite clay are both widely accepted as waterproofing materials.

Bentonite Installation

Bentonite waterproofing is almost always installed as a membrane rather than its raw clay form. These membranes are most often installed on the foundation of a structure as it’s being built. The membranes create a water and vapor seal protecting the structure from the organic elements below grade around the home. Installing a bentonite waterproofing membrane prior to backfilling the foundation of a structure is key to incorporating a successful waterproofing system in your construction project.

Advantages of Using Bentonite

Bentonite, no matter the form it comes in, has plenty of advantages. While its biggest downfall is the need to place it around the entirety of the foundation, that doesn’t stop business owners from seeing the advantages.

It can be easily installed in any climate or temperature. That means there’s no need to wait till warmer months roll around. It can bridge cracks in the concrete up to 1/4 inch, has little to no restrictions, adapts to complex geographical shapes, and provides easy leak detection if the system begins to fail.

Injection Waterproofing

Within the niche of waterproofing injection, there are several variations. Bentonite injection is one of those variations that’s another popular solution for waterproofing. The injection technique of waterproofing is used most often when a building has begun to leak. In most cases, injection is used because installing a membrane wouldn’t be possible after the building project has been completed.

Injection Waterproofing Process

The process of injecting waterproofing material into the foundation of the building can be tedious. Small holes are drilled along the foundation or near cracks in the concrete. Then, these holes are fitted with injection fittings. Finally, an expanded solution is pushed into the holes. The solution travels through the holes and to the outside of the building, where it grows and creates a waterproof barrier.

If the process is done correctly by an experienced and professional waterproofing company, the next time rain hits, you won’t have any water inside your building. It’ll stay dry no matter how wet the conditions become.

Advantages of Injection Waterproofing

One of the primary advantages of using injection waterproofing is the minimally invasive nature of the product. In most cases, the area around the exterior foundation of the building will only be slightly disturbed. Because of this, you’ll be able to waterproof your structure without disrupting any of the operations while leaving any landscaping intact.

The Best Waterproofing Solution

If you’re going to find the best waterproofing solution, you need to work with the best waterproofing and water mitigation company in your area. Moreover, you need to make sure that you start a conversation with them before there’s water in your basement. Waiting until you’re wet isn’t an active solution to mitigate water damage. Instead, form an action plan so that you’re able to get a bentonite membrane or other form of water mitigation installed to ensure that no matter the conditions, your building stays dry.

The installation of a membrane or bentonite clay system is an extensive process. It should be started during the construction project in order to ensure that there aren’t any water issues before the project is even completed.
