A waterstop is a material embedded in the concrete, with the singular purpose to obstruct the passage of water through the joint. In other words, it is not an elastomeric sealant adhered to the exposed surface of a joint.
Where is waterstop used?
Most varieties are manufactured exclusively for use in cast-in-place concrete construction joints, while some types can also be used with expansion joints.
What is bentonite used for?
The main uses of bentonite are in drilling mud and as a binder, purifier, absorbent, and carrier for fertilizers or pesticides. As of around 1990, almost half of the US production of bentonite was used as drilling mud. Minor uses include filler, sealant, and catalyst in petroleum refining.
