Aquablok is a composite-aggregate technology resembling small stones with a dense aggregate core, clay-sized materials and polymers. For most applications, Aquablok’s clay sealant is composed mainly of Bentonite clay. However, other materials may be used to meet project needs, including use in saltwater environments. Aquablok particles expand with hydration and will act as a barrier for water and chemicals. In addition to providing a lining solution, Aquablok is also capable of facilitating wetland restoration by transferring plant seeds to a targeted area.
