Hydrophilic waterstops are joint sealing profiles typically made of bentonite or thermoplastic elastomer (TPE) hydrophilic materials. They have a rectangular cross-section and come in rolls of varying lengths depending on the profile size. The hydrophilic material has a molecular structure that attracts water molecules and absorbs liquid through hydrogen bonding.
