A Fibermax Composites innovative, rather simple way to utilize a freshwater spring under a building
construction site. The spring flows out of a well, at the bottom of a car elevator pit, in the underground parking space of the 6 storey building. No available open space on the plot, has made moving the pumping well out of the building perimeter impossible. The bottom of the elevator pit is the lowest level of the building. An attempt to close the well with fast setting cement has failed, because of water pressure. Fibermax Composites has worked out this solution to avoid the traditional costly injection techniques, and at the same time save the freshwater spring for later use.
The innovative solution comprises a prefabricated frame with screw sockets. This frame (in blue color) is carefully consolidated on the concrete floor with an epoxy adhesive system and some plugs. 100% watertightness between the frame and the concrete floor has to be reassured. After consolidation, the prefabricated (white) lid with a silicone flange is screwed on to suppress the water. This act of removing the pumps and screwing on the lid is made in a fast, well organized move so to avoid flooding. The lid has a small curve or arch, so just a few screws on top of this arch has made it rapidly watertight with ease. A pout on the lid will allow easy water extraction later on.

No freedom from any patent owned by Fibermax Composites or others is to be inferred.
