Use it as a standalone triangular bead or to bond SikaSwell A and P Profiles to prepared concrete.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"positioning-section\" aria-labelledby=\"positioning-heading\"\u003e\n    \u003ch3 id=\"positioning-heading\"\u003eWhy this product exists\u003c\/h3\u003e\n    \u003cp\u003eConstruction joints and penetrations create potential paths for water through concrete. SikaSwell S-2 is placed within the concrete structure so contact with water causes the sealant to swell and seal these details.\u003c\/p\u003e\n    \u003cp\u003eThe expansion is reversible. In a totally dry state the sealant shrinks towards its original dimensions, then expands again when exposed to water. It is permanently water resistant through wet and dry cycles.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"specs-section\" aria-labelledby=\"specs-heading\"\u003e\n    \u003ch3 id=\"specs-heading\"\u003eThe numbers that matter\u003c\/h3\u003e\n    \u003cp\u003eIn tap water, volume change is less than 25% after 1 day and less than 100% after 7 days. This controlled swelling is the mechanism used to seal the joint when water reaches the installed sealant.\u003c\/p\u003e\n    \u003cp\u003eSikaSwell S-2 is recommended for sealing against water pressures up to 2 bar. Above 2 bar it may only be used as a supplementary joint sealing solution.\u003c\/p\u003e\n    \u003cp\u003eAt +23 °C and 50% relative humidity, curing is approximately 2 mm after 1 day and 10 mm after 10 days.
