SikaSwell® P Type H
SikaSwell® P Type H is a hybrid profile with superabsorbents and a rubber core. It swells in contact with water to seal all types of construction joints and penetrations in concrete structures.
- Mechanical stability due to rubber core
- Highly economical joint sealing solution
- Versatile solution for joints and details
- Protective layer prevents premature swelling
- Permanently water resistant (wet & dry cycles)
- Resistant to many chemicals
- Fast and easy to apply
- Good adhesion to various substrates
Usage
The Product is used for the following waterproofing applications:- Construction joints
- Pipe and steel work penetrations through walls and floor slabs
- Around all types of penetrations and connection joints
- Construction joints in cable ducts
- With pre-cast element structures

Change of Volume
| Time | Demineralised water | 5 % saline solution |
| 1 day | > 100 % | > 10 % |
| 7 days | > 300 % | > 25 % |
Note: Swelling properties in saline water will be reduced and delayed. Use SikaSwell® A Maritim version.
Note: In a totally dry state, SikaSwell® P Type H shrinks to the original dimensions. The profile then expands again upon further contact with water.
Swelling Pressure
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.
Note: In an ideal concrete structure the material can develop a swelling pressure up to > 10 bar.
Service Temperature
Minimum | -20 °C |
Maximum | +50 °C |
Application
Substrate Moisture Content
Dry or matt damp. Do not apply in construction joints with existing standing water.
Ambient Air Temperature
Minimum | +5 °C |
Maximum | +35 °C |
Substrate Temperature
Minimum | +5 °C |
Maximum | +35 °C |
SUBSTRATE QUALITY
The substrate must be sound, clean, dry or matt damp, free from all surface contaminants that could impair the adhesion.
SUBSTRATE PREPARATION
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 by an appropriate Sika leveling mortar or mechanical treatment before the SikaSwell® S-2 and SikaSwell profile is applied.
FRESHLY CAST CONCRETE
Freshly cast concrete can be smoothed with a batten where SikaSwell® S-2 is to be placed.
APPLICATION
IMPORTANT
Concrete cover
Insufficient concrete cover, low density concrete or voids will prevent the SikaSwell® profile from developing its waterproofing function.
- Place the SikaSwell® profile in the centre of the concrete structure.
- In reinforced concrete maintain a minimum cover of 8 cm on both sides.
- In unreinforced concrete maintain a minimum cover of 15 cm on both sides.
SEALANT WITH A SIKASWELL® PROFILE
- Apply SikaSwell® S-2 adhesive in a narrow bed (size of triangular section ~12 mm tall and ~12 mm wide ) onto the prepared substrate. Extrude enough material to level the roughness of the substrate.
- Press the SikaSwell® profile firmly into the fresh applied SikaSwell® S-2. Place the SikaSwell® profile within a maximum of 30 minutes (+23 °C / 50 % r.h.).
- Ensure full and continuous contact between the SikaSwell® S-2 and both the SikaSwell® profile and the substrate is achieved.
- Allow SikaSwell® S-2 to harden minimum 12 hours before placing concrete. For pouring height > 50 cm, SikaSwell® S-2 must harden for at least 24 hours before placing concrete.
- Protect the SikaSwell® S-2 and the SikaSwell® profile against water (for example, rain) until the concrete is placed.
- During placement compact the fresh concrete well around the SikaSwell® profile to achieve dense concrete without any honeycombing or voids.
CLEANING OF TOOLS
Clean all tools and application equipment immediately after use with Sika® Colma Cleaner. Hardened material can only be removed mechanically.
