Project: Sealing transformer wells
Many transformer wells alongside to the runways of Schiphol Airport were leaking. These wells are partly below ground and neaded to be sealed from inside out.
Liquid Rubber was used to seal all the connection joints inside the wells. Liquid Rubber is resistant against a negative water pressure of 1,5 bar that makes it perfectly suited for a job like this.
The connections where pre-treated with the Liquid Rubber JointFiller. Afterwards the Liquid Rubber HB S-200 combined with Geotextile was applied to seal the entire joint.
By now, many wells are done and Schiphol Airport is very happy with the work so far.
