Bentonite clay is a natural material that has been used for many hundreds of years to prevent water intrusion in basements and foundations. It expands when wet, filling up gaps and cracks to form a barrier against moisture that is dense and impermeable.
One of the biggest benefits of bentonite clay is that it is eco-friendly. In contrast to chemical sealants, it is non-toxic and safe for the environment. When used around exterior basement walls, the clay creates a self-sealing layer that will continuously conform to movement in the soil, ensuring that it remains a protective layer even as there is the slightest movement of the foundation over time.
Bentonite may be used in panels, sheets or loose layers, often used in combination with drainage systems for greater effectiveness. Its expansion capability ensures that tiny cracks or voids are automatically sealed lowering the risk of leaks and water damage.
Maintenance is minimal. Once in place, bentonite clay is able to deliver decades of protection with relatively little intervention, which makes it an effective and affordable choice for basement waterproofing solutions.
Conclusion
Bentonite clay is a natural, consistent solution to basement waterproofing. Its self-sealing properties, durability and eco-friendly nature make it an excellent choice for any renovation where moisture protection is a priority. Using bentonite means basement walls are dry, safe and resilient for years to come.
