Specification of Sika Hydrotite Waterstop
DESCRIPTION
Sika® Hydrotite is a hydrophilic rubber sealing strip used to seal site formed construction joints.
Note: Sika® Hydrotite is not a sealing material for expansion joints and should not be used as such
CHARACTERISTICS / ADVANTAGES
▪ In addition to the packing effect which conventional sealing materials have, Sika® Hydrotite expands as it absorbs water and fills up concrete joint gaps conforming to the gap variations and thus ensuring excellent sealing
▪ In the case of conventional waterstops, air tends to be trapped at Point A (Figure 1) after their application, thus adversely affecting the sealing effect. In contrast, Sika® Hydrotite is free from protrusions which could have an adverse effect on placement (Figures 1 & 2)
▪ Sika® Hydrotite is easy to handle as it is lightweight
▪ Sika® Hydrotite is treated with an expansion delay coating to preserve it from the influence of water from freshly poured concrete and prevent expansion taking place before curing of concrete
