Specialising In The Construction &  Sealing Of Dams, Ponds And Streams

Dam Sealers is a South African supplier and installer of high-quality Sodium Bentonite Clay.

Bentonite, often called “The Miracle Clay” is a pure, organic, natural product mined and produced in South Africa that has a wide range of uses, however here we will focus on using it mainly for the sealing of dams, ponds, streams, and other waterways.

An on-site consultation will be a great investment of your time and money in understanding the pros and cons of sealing your dam, pond or streams with bentonite. We will spend as much time as you need to walk you through the design & construction process, giving you our professional insight from having constructed and sealed thousands of square meters.

At the end of this consultation and at your request, we will prepare a detailed quote giving you all the information you need to make an informed decision on your project, on approval we will review available dates for your project and when you are ready, sign a contract to begin development on your future waterscape.
