Hotel Il Sereno, Torno

by

The symbiosis between Il Sereno di Torno and Lake Como began right from the laying of the first stone. The design hotel has literally risen from the waters of the Lario.

The charming country road that leads to the hotel is in fact not passable by heavy vehicles, so all the material for the construction arrived by lake on board barges.

The dominus of this complex construction site was the architect Fabio Curcio Valentini, construction manager and coordinator of the architectural project of Patricia Urquiola, who also created the contemporary interior design of the Luxury Hotel.

The construction was consolidated with poles placed in the water, and the area dedicated to the technical systems was obtained by digging into the granite rock without using explosives, up to a depth of seven meters below the level of the lake and creating the waterproof structures with the Drytech Tank system.

The old dock was incorporated into the new building of four floors above ground and two underground floors.

The lake-front wing towards Como hosted the underground garage and the heated outdoor swimming pool, also a Drytech tank and covered in Brazilian karst stone.

Double waterproof pump wells, Copenhagen

by

Drytech has designed a special waterproof pump shaft that allows companies to create pumping points inside the bed.

The wells are made in the Bedano workshop, in Switzerland, and shipped to the construction site, wherever it is in the world, where they are prepared by the Drytech technician.

This is the case of the construction site opened directly in the North Sea, where 36 pump wells were installed, subsequently sealed and incorporated into the bed.

Once its function is exhausted, the Drytech pump well is waterproofed both externally and internally.

Once the casting is complete, the joint between the well and the bed is injected with DRYflex expansive resin, which seals the element by pressure, wrapping around the entire thickness of the bed.

Any water flows inside the well are instead rendered harmless by the lid sealed with gaskets both on the circumference of the well and on each of the sealing bolts.

The use of the Drytech System resulted in a saving of several weeks on the time required for the construction of the waterproof basement.

Algiers subway restoration

ytech restored the waterproofing of 5 tunnels and 5 stations of the Algiers metro, sealing over 4 km of underground tunnels.

Drytech restored the waterproofing of 5 tunnels and 5 stations of the Algiers metro, sealing over 4 km of underground tunnels.

The proximity to the sea exposes the structure to a water table of 6-8 meters.

During the construction phase, various systems were used to waterproof tunnels and stations, but none of these managed to guarantee 100% waterproofness.

Hence the need for definitive reorganization. The Algerian Ministry of Transport has commissioned the Eurometro company – London consultants specialized in the subway sector – to identify a solution to the problem of infiltrations.

After a worldwide survey, Eurometro proposed the Drytech Restoration System, based on injections from the inside of the DRYflex acrylic resin structure.

The Line 1 tunnel is made up of 10 meters long waterproof concrete segments, connected by 2 recovery joints interspersed with an anti-seismic movement joint.

Waterstop tapes were inserted into the joints, which only worked in 45% of the joints.

The joints of the adjacent structures, of the stations, of the ventilation ducts etc., were instead waterproofed with bentonite expansive profiles, the expansion of which however proved to be limited compared to the shrinkage of the concrete.

Even the jet shots at the air intakes showed infiltrations.

The thermal changes to which they are naturally exposed produce structural movements that split the polyurethane used to waterproof them.

Polyurethane, in fact, being semi-rigid and adhesive, undergoes the movements of the structure and, when they are particularly large, it cracks or loses adhesion.

Finally, shrinkage cracks were produced in the concrete which represented as many points of permeability of the structure.

The Drytech rehabilitation intervention for the waterproofing of the Algiers Metro was cataloged with the REAL system of Sir of Turin.

The application creates a virtual reconstruction of the structure, with all the information relating to the remediation intervention.

An X-ray that allows a quick and interactive consultation of images and data relating to the individual interventions performed.

Vetropack water tower, Corsico

by

Drytech restored the water tower of the Vetropack plant in Corsico with injections of waterproofing resin carried out from the outside, without having to empty the barrel.

The fire-fighting water reserve was thus guaranteed to the continuous-cycle industrial plants and the company did not have to rent a tanker for the fire brigade.

With the Drytech system it is no longer necessary to dive into the barrels, with all the related logistical and safety implications.

For the intervention, Drytech technicians exploited a scaffolding already set up by a company to restore the external surface of the tower.

Normally the Drytech Rehabilitation System allows the practical use of aerial platforms, with a consequent saving on costs and time for setting up the scaffold.

Private house, Gelterkinden

by

Designed with the expressive power of a sculpture, the Chienbergreben private house in Gelterkinden follows the slope of the land, on the border between the town and the agricultural area.

The underground structures were built with the Drytech Tank System, which made them impermeable to both groundwater and slope water.

The adoption of the Drytech System, which provides for a single waterproof concrete structure, has allowed the project to respect the figure that defines it architecturally even in the underground part.

The entire structure of the building is in fact made of exposed concrete with disposable horizontal formwork: inside as well as outside.
