SikaSwell® S-2

• Conforms to LEED v2009 IEQc 4.1 Low Emitting Materials-Adhesives and Sealants (VOC content requirement: < 420g/l less water)

1-part polyurethane, moisture curing

9 months from the date of production

The product must be stored in original, unopened and undamaged packaging in dry conditions at temperatures between +5 °C and +25 °C.
Always refer to packaging.

Stand-alone solution:

With a SikaSwell® profile:

Note: In a totally dry state, the Product shrinks to its original dimensions. The product then expands again upon further contact with water.

The pressure developed by the material depends on the stiffness of the surrounding concrete structure, which is influenced by the concrete quality, voids, gaps and other weaknesses.

In an ideal concrete structure the material can develop a swelling pressure up to > 10 bar.

Dry or matt damp. Do not apply in construction joints with standing water.

Consumption depends on the roughness and absorbency of the substrate.

Note: These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

The substrate must be sound, clean, dry or matt damp and free from all surface contaminants that could impair the adhesion of the sealant.

EXISTING CONCRETE

Rough surfaces are susceptible to leaking. If the surface roughness cannot be leveled with SikaSwell® S-2 the roughness need to be removed. Use an appropriate Sika leveling mortar or mechanical treatment before the SikaSwell® S-2 and SikaSwell® A profile or SikaSwell® P profile is applied.

FRESHLY CAST CONCRETE

Freshly cast concrete can be smoothed with a batten where SikaSwell® S-2 is to be placed.

Clean all tools and application equipment immediately after use with Sika® Colma Cleaner. Hardened material can only be removed mechanically.
