Tugboat Platform, Ashkelon
The project included disassembling existing concrete in the platform and casting a new water front beam descending to a depth of half a meter beneath sea level in order to serve as defense to the existing structure.
The cast was implemented using slag cement, strong non-contractible concrete, chloride impermeable and which does not crack. Due to the concrete being especially liquid a completely impermeable mold was required so that concrete or cement will not flow into the sea.
Likewise we implemented platform shields, sentries and platform ladders.
This platform is used by fuel tank tugboats.

In this project we were required to implement an underwater cast.
The underwater adapted cast mold was to be completely sealed from all sides so that concrete will not flow into the sea. Molds as such are usually made of metal, require complex prolonged preparation, and the underwater sealing may not be sufficient. Moreover, the preparation cost is high.
The solution we presented in order to execute high quality, accurate implementation whilst preventing the flow of concrete into the sea entirely and at reduced cost was, casting prefabricated element to be used as a bottom lost mold.
The element was attached by divers to the existing platform wall, sealed by a designated material suitable for underwater sea procedures.
Since the concrete prefabricated element is rigid and thick, complete sealing was achieved and any possible flow of concrete into the sea was prevented.
After constructing the elements and sealing them, the panel-composed wall mold was constructed upon the prefabricated elements and was pressed onto them to achieve complete sealing and the prevention of concrete flow into the sea.
