What is Tanking Slurry

Tanking Slurry – What is It and how is it used?

Tanking slurry is a type of semifluid mixture that is used as a waterproofing sealant in basement tanking. It is often used on basement walls and floors to prevent water infiltration. Tanking slurry is also used on above-grade walls to prevent water seepage. In this blog post, we will discuss what tanking slurry is, how it works, and some of its advantages and disadvantages.

What is Tanking Slurry?

Tanking slurry is a type of waterproofing sealant that consists of cement, sand, and water. It can be applied to concrete, brick, stone, and other masonry surfaces. When tanking slurry dries, it forms a waterproof barrier that prevents water from seeping through cracks and pores in the masonry surface.

How does Tanking Slurry Work?

Tanking slurry is a type of waterproofing sealant that consists of cement, sand, and water. It can be applied to concrete, brick, stone, and other masonry surfaces. When tanking slurry dries, it forms a waterproof barrier that prevents water from seeping through cracks and pores in the masonry surface.

Advantages of Tanking Slurry

One of the main advantages of tanking slurry is that it is relatively inexpensive. Tanking slurry can also be applied to a variety of different surfaces, including concrete, brick, stone, and other masonry surfaces. Additionally, tanking slurry dries quickly and forms a durable waterproof barrier.

Disadvantages of Tanking Slurry

One downside of tanking slurry is that it can be difficult to apply evenly. Tanking slurry can also be difficult to remove if it needs to be repaired or replaced. Additionally, tanking slurry may not be effective on surfaces that are porous or have large cracks.

Conclusion

Overall, tanking slurry is an effective way to waterproof basement walls and floors. It is also relatively inexpensive and dries quickly. However, tanking slurry can be difficult to apply evenly and may not be effective on surfaces that are porous or have large cracks.
