AKILA® sealing system
Sheet pile accessories
Technical information
The AKILA® sealants MSP-1 (for single piles) and MSP-2 (for double piles) belong to the family of silane modified polymers (MS-Polymers). Both products resist humidity and weathering. Their main characteristics are:
- single component elastic sealants with a density of 1.41 g/cm3 for MSP-1 and 1.48 g/cm3 for MSP-2
- UV-stable
- excellent adhesion to steel
- resist temperatures between -40°C and +90°C (up to 120°C for short periods)
- elongation at break > 380%
- Shore A hardness after complete polymerization 58 for MSP-1 and 44 for MSP-2 (after 14 days)
- durable in contact with freshwater, seawater, as well as various hydrocarbons, bases, and acids
Environmentally certified sealant
AKILA® is a brand new environmentally friendly, high performance sealing system for ArcelorMittal steel sheet piles. It is based on three sealing "lips" made of silane modified polymers (MS-Polymers) mechanically extruded into the free interlocks. These single component elastic sealants are resistant to humidity, weathering, and extreme temperatures, are UV-stable and offer excellent adhesion to steel.
The AKILA® sealing system is environmentally certified and suitable for contact with ground water. MS-Polymers are considered environmentally friendly as they are solvent free and do not contain isocyanates.

Paper abstract
Vehicle traffic and lack of parking space is one of the main challenges for big cities. Especially in city centres, land is very expensive and the trend to increase parking capacity is to build underground structures. In this article, an innovative, economical, and environmentally-friendly solution for underground car parks built with steel sheet piles is described. Several aspects like fire safety, impervious walls, vertical bearing capacity, environmental impacts, and reduction of traffic due to construction vehicles are discussed.
