Waterproofing Drytech Italia, Montano Lucino Como
EX-POST WHITE TANK, ITALY / Due to an incorrect evaluation of the water table, waterproofing of the underground structure in this high quality residential complex was not envisaged.
Unfortunately, when construction was completed a seasonal peak in the water table flooded the level -2, making the garages unusable.
At this point, Drytech was involved to restore the underground structure.
The analysis of the structural and environmental situation by Drytech Engineering identified the best solution creating the ex-post Drytech Tank. The industrial floor was therefore demolished built above the gravel fill-in. The water table was controlled with a well-point system.
The crack inducers were then installed in the foundation bed and the foundation bed/wall joints and foundation bed columns were prepared with DRYset Channel. The numerous penetrations produced by the well-points were also appropriately prepared for waterproofing injections at the end of the concrete’s curing period.
The foundation bed was then cast using waterproof concrete based on the Drytech mix design. Based on the characteristics of the plant chosen by the construction firm, Drytech Engineering develops a mix design to create concrete which guarantees excellent workability. In order to guarantee the upper position, it was necessary to create the sealed foundation bed and the industrial floor as a single elicotterato cast wet-on-wet. For this system a special version of the Drytech waterproof concrete mix design was developed.
At the end of the concrete’s curing period, Drytech completed the injection of the planned cracks, the joints and the penetrations with the DRYflex expanding resin.
Due to the resin’s elastic quality, injections can be repeated over time ensuring the system can be maintained.
The creation of the Drytech ex-post foundation bed ensured the underground structure was made waterproof and enabled the garages to be handed back to the owners perfectly useable.
