Solutions with Sika Systems
SikaSwell -P Profiles
Water Swellable Sealing Profiles for Construction Joints and Penetrations
s Swells in contact with water s Easy and secure application s Double swelling action: seals in two phases
SikaSwell -P Profiles
The new Sika Solution for Watertight Construction Joints
Typical Applications for SikaSwell -P Profiles
s Sealing of daywork joints (wall/wall, wall/floor, floor/floor) s Connecting new to existing construction
s Sealing of precast concrete culverts and manhole rings s Sealing of penetrations pipe entries, utility services etc.
Construction Joints
Penetrations
Function
Joint sealing profiles which swell in contact with water
After contact with water the profile swells. The resultant volume greatly increases the length of path, and acts as a barrier for any possible water penetration.
SikaSwell -2003 Before water exposure
After water exposure
Advantages
s Swells in contact with water s Permanently water resistant s Highly elastic s Easy, secure application s Needs no curing time s Pretreated to avoid premature swelling on site
Limitations
s Not suitable for movement joints s Cannot be injected s Although SikaSwell-P has been tested to water pressures above 3.5 bar, due to the limited sealing distance, it is not normally recommended to water pressure higher than 0.3 bar. s In case of a rapidly rising ground water table, no instant or immediate waterproofing or sealing is possible due to the time required for the profile to swell.

Installation / Fixing Detail
Adhesive Selection Substrate The substrate should be surface dry, with no standing water, free of dust and loose particles, cement laitance, voids and protruding coarse aggregate. Dependent on substrate type and condition: Smooth dry substrate Use Sika Contact Adhesive Rough, dry or surface dry substrate Use SikaSwell -S extrudable, swelling sealant/adhesive

s Storage/Shelf life s Packaging
> 150 % The profiles have a volume increase of minimum 150% if stored in tap water at 23 C for 14 days. In salty or contaminated water the swelling properties may be reduced and / or delayed. Stored in cool and dry conditions, shelf life is at least 12 months from date of supply. Rolls packed in cardboard boxes, quantity depending on type of profile, consult technical data and price list.
