Renovation with Ex-Post Drytech Tank, Italy

Due to an underestimation of the water table, the waterproofing of the underground in this prestigious residential complex was not planned.

Unfortunately, after the construction was completed, a peak of the seasonal water table flooded the -2 level, making the garages unusable.

At this point Drytech was involved to restore the underground.

The analysis of the structural and environmental situation by the Engineering has identified the best solution in the construction of an ex-post Drytech Tank.

The industrial floor built above the gravel filling was therefore demolished. The water table was brought under control with a well-point system.

We then proceeded to lay the cracking elements in the stalls and prepare the stalls / walls and stalls / columns joints with the DRYset Channel.

The numerous crossings produced by the well-points have also been suitably prepared for the waterproofing injection, once the concrete has matured.

The new waterproof concrete slab based on the Drytech recipe was then cast.

To ensure the height of the extrados, it was necessary to create the sealed platform and the industrial floor in a single fresh-on-fresh helicopter jet.

When the concrete has matured, Drytech has perfected the injection of programmed cracks, joints and crossings with DRYflex expansive resin.

Due to its elastic quality, the resin is re-injectable, so it guarantees the possibility of maintaining the system over the years.

The construction of the ex-post Drytech platform made it possible to waterproof the basements and to deliver the properties with the usable garages.

Drytech Ex-Post tank for oil plant, Italy

A valve park sorts the crude oil unloaded from tankers to storage tanks.

In the specific case of the plant’s leaks in the ground, it was necessary and urgent to restore it, but without the possibility of interrupting its activity.

It was therefore decided to create an impermeable tank below the system of valves, which had been placed in contact with the ground.

With an almost archaeological approach, the ground beneath the plant was excavated by gradually inserting supports to the pipelines.

Then we proceeded to the casting of the drytech waterproof concrete slab and walls and, when the casting was ripe, the waterproofing injection of DRYflex resin in the programmed cracks, in the construction joints and in the crossings, including the pipe supports, which were left in place.

The intervention, designed and coordinated by Drytech Engineering, restored the system to safety and made it definitively accessible for maintenance.
