ADEKA P-201 is an excellent choice to stop leaks if the existing expansion joint material or center bulb waterstop has failed. This method involves removal of existing material down to a depth of approximately 3? or more. If the remaining material is in good condition, apply 1/2? layer of P-201 and compress with one or more oversized closed cell backer rods as shown in details below.  Backer rods should be about 25% bigger in diameter compared to the joint width.  This is to insure a tight fit   If necessary insert oversized backer rod first then P-201 then more backer rod as necessary to fill void to near top.  Complete joint repair with your choice of joint sealant.
