Typically hydrophilic (water swelling) waterstops are not recommended for expansion joints.  However in certain cases and under the right conditions ADEKA WATERSTOPS make the job of sealing expansion joints easier and more secure.

The choice of product depends on expected expansion and joint width. Either ADEKA KM-3030M or ADEKA P-201 is an appropriate product to use depending on conditions.

Use KM-3030M in new construction where joint width is 1/2? and expansion will be 1/2? or less (approximately).  This design is excellent for shear movement as well.  See Detail 1. (Check hydrostatic head tests at this link)
