HYDROPHILIC STRIP FOR SEALING SITE FORMED CONCRETE JOINTS
Description
Sika HydrotiteCJ-0725-3K is a hydrophilic rubber sealing strip used to seal site formed construction joints.
Note: Sika Hydrotite CJ-0725-3K 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 CJ-0725-3K 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 CJ-0725-3K is free from protrusions which could have an adverse effecton 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
