Product Description:
SikaSwell® S-2 is a 1-part, hydrophilic polyurethane sealant that expands upon contact with water, effectively sealing construction joints and penetrations in concrete structures. It is used to adhere SikaSwell® A and SikaSwell® P profiles to the concrete structure.
Usage:
Used to seal:
- Construction joints
- Pipe and steel work penetrations through walls and floor slabs
- Around all types of penetrations and construction joints
- Construction joints in cable ducts
SikaSwell® S-2 is used for fixing and adhering the following swellable profiles:
- SikaSwell® A
- SikaSwell® P
Please note:
- Do not use SikaSwell® S-2 for movement joints.
- SikaSwell® S-2 is suitable for sealing against water pressures up to 2 bar.
- For pressures above 2 bar, use an alternative or supplementary Sika® joint sealing solution.
Features / Advantages:
- 1-part, easy and fast to apply
- Highly economical joint sealing solution
- Versatile solution for joints and details

Shelf Life:
- 12 months from the date of production
Storage:
- The Product must be stored in original, unopened and undamaged packaging in dry conditions at temperatures between +5 °C and +25 °C.
Application Steps:
Step 1 : Pre-Application
Ensure substrate is sound, clean, dry or matt damp and free from all surface contaminants that could impair the adhesion of the sealant.
Prior to applying SikaSwell® S-2 and the SikaSwell® A or SikaSwell® P profile, smooth the area with a suitable Sika® leveling mortar or through mechanical means.
Step 2 :
Apply SikaSwell® S-2 adhesive in a narrow bed onto the prepared substrate, extruded in a triangular section ~12 mm wide and ~12 mm deep.
Note: Extrude enough material to level the roughness of the substrate.
Step 3 :
Press SikaSwell® profile firmly into the freshly applied SikaSwell® S-2.
Note: Place the SikaSwell® profile within a maximum of 30 minutes (+23 °C / 50 % r.h.). Ensure that full and continuous contact between the SikaSwell® S-2 adhesive and both the SikaSwell® profile and the substrate is achieved.
Step 4 :
Allow SikaSwell® S-2 to harden for at least 12 hours before placing concrete. For pouring height > 50 cm, allow SikaSwell® S-2 to harden for at least 24 hours before placing concrete.
Step 5 :
Protect the SikaSwell® S-2 and the SikaSwell® profile against water – for example, rain – until the concrete is placed.
Step 6 :
When placing concrete, compact the fresh concrete well around the SikaSwell® profile to achieve dense concrete without any honeycombing or voids.
