With typical formulations ranging in size from ¼” to ¾” (in diameter), AquaBlok looks, feels, and handles – at least before it gets wet, that is – much like any crushed stone that would be used to bed a pipe. The difference lies in AquaBlok’s unique veneer of bentonite that wraps each individual stone. Working together, the stone and the clay offer a pourable fill that “self-compacts” when exposed to water. The resulting body of material never sets firm like concrete, but instead has a consistency often described to be like “very crunchy peanut butter.”
When placed in a trench perpendicular to a sewer line or other conduit (as pictured at left), product can be wetted to produce a durable, structurally stable barrier that maintains a very low permeability. The coating of individual particles swells against the exterior sidewalls of the pipe and “self-keys” into surrounding soil without the need for benching, installation in lifts, or manual re-compaction. The result: an economical and technically superior barrier.
