Certificate type
Hydrophilic 'donut' for the external sealing of tie bolt sleeves with an external diameter between 24–30 mm.
Hydroswell TBSD24 consists of hydrophilic water swellable synthetic rubber. It expands in contact with water to form an external watertight seal for tie bolt sleeves.
Designed to seal tie bolt sleeves by preventing water tracking along the outside of sleeves. Penetrating water in contact with TSBD24 will be stopped by the expansion of the hydrophilic material.
