P-201 or KBA hydrophilic waterstops are appropriate for precast segment joints in manhole applications. P-201 or KBA waterstops must be compressed when segments or in their final position. Do not assume "swelling" to fill the gap.
Example of precast joint with P-201. KBA may be used in place of P-201.
