Drytech Ex-Post tank for oil plant, Italy

by
To protect the ground from leaks in an oil valve park, Drytech built a watertight tank underneath the plant without interrupting its operations.

To protect the ground from leaks in an oil valve park, Drytech built a watertight tank underneath the plant without interrupting its operations.

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.

Gioia Garden, Milan

by
Architect Diego Fumagalli designed the Gioia Garden residences starting from the classic Milanese palace.

More than a dialogue, a hug. Architect Diego Fumagalli designed the Gioia Garden 1 and 2 residences starting from the stylistic features of the classic Milanese palace with which they border.

He created an architectural continuity made up of citations and references, which harmonizes the relationship between the two buildings, enhancing their formal differences.

Starting from this connection, the buildings in via Melchiorre Gioia 177/179 develop their own architectural identity, fitting perfectly into the context.

At the point of contact between the two buildings, the height of the volumes was respected and, in Gioia Garden 1 and 2, the string courses of the residential levels are barely mentioned, to conceal the slight differences in the height of the floors compared to the historic building.

Once continuity with the existing one has been established, the architecture of the new building unfolds all its character: with the articulation of the facade through the volumes of the terraces and the deep recesses of the winter gardens; with the hanging gardens dotting the building at different levels; with the three additional floors, progressively set back from the main facade.

The tallest volume itself contains a further reference, taking up the horizontal shutters that characterize nineteenth-century architecture.

Due to the presence of the aquifer and the proximity to the Naviglio della Martesana, all the underground structures, including garages, were built with a 2,753 m2 Drytech Tank.

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

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.

Allianz Isozaki Tower, Milan

by
The Isozaki Tower in the CityLife district, inspired by Costantin Brancusi's endless column, has become one of the symbols of the city of Milan.

The Isozaki Tower, inspired by Constantin Brancusi’s endless column, has become one of the symbols of the city. Designed by the Japanese architect Arada Isozaki together with the Italian architect Andrea Maffei, the skyscraper is the headquarters of Allianz in Italy.

The building, which can accommodate up to 3,800 people, is the tallest skyscraper in Italy by number of floors (50) and according to the highest occupied floor criterion (with its 207 m).

Drytech has designed the waterproofing of all the structures below the project ground level. The fire-fighting tanks, the system tunnels, the multi-lancet windows and the lower sections were therefore built with the Drytech Tank technology.

Hotel Il Sereno, Torno

by
The symbiosis between the Hotel 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 symbiosis between the Hotel 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.

Giusti Wine Cellar, Nervesa

by
The Giusti Wine cellar in Nervesa della Battaglia designed by architect Armando Guizzo

The new Giusti Wine cellar in Nervesa della Battaglia was designed by architect Armando Guizzo to tell a story of ties with the territory and harmony with nature.

Ermenegildo Giusti is a convinced supporter of viticulture that respects the environment and people. Giusti wanted a winery that plastically expressed the values of sustainability and integration.

The cellar is two thirds underground, while the emerged part integrates with the territory, not only architecturally but actually: the undulating roof with its rows is not an aesthetic exercise, but rather an authentic wine-growing area, structured to support the weight of the agricultural vehicles and which produces bunches exactly like the surrounding rows.

Particular attention was paid to the roofing, with an in-depth study of the materials used for growing the vines. First of all, the natural soil that covered the area before the construction site was excavated was restored on the roof.

Below this original soil, several layers of different natural materials were laid, including expanded clay, which in addition to ensuring the growth of the vines, make an important contribution to the energy saving of the building.

The entire hypogeum was created with a single waterproof Drytech Tank.

Harbour parking, Loano

by
The Marina di Loano underground car park has 400 parking spaces below sea level. It was built with the waterproof structure Drytech Tank.

The new car park of Marina of Loano has 400 parking spaces below sea level.

Loano is one of the most interesting tourist ports in Italy and the Mediterranean for pleasure boating.

The expansion of the Marina involved a surface area of 358,000 m2 and involves the construction of over 1,200 berths, with the possibility of mooring boats up to 50 meters in length.

The port and city are served by a car park with 1000 parking spaces, of which 400 are underground. Or rather, submarines.

The underground car park of the Marina di Loano, created with the Drytech Tank System, drops 4 meters below sea level.

Prefabricated waterproof tanks, Loano

by
The fuel tanks of the service station of the new tourist port of Loano were built ashore by the company PB Lavori Marittimi of Ancona with the Drytech Tank technology

The fuel tanks of the service station of the new tourist port of Loano were built ashore by the company PB Lavori Marittimi of Ancona with the Drytech Tank technology.

The construction of prefabricated tanks has the advantage of a more practical processing and with a higher quality standard, since the jet in water often produces gravel nests, regardless of the expertise and care of the diving technicians.

Where transport does not constitute an obstacle, the prefabricated tank is therefore preferred.

The tanks were built on the dock of the shipyard area of ​​the new port of Loano and Drytech Engineering collaborated with the designer already in the design phase, for the aspects related to waterproofing and the problems of transporting the tanks.

Made of XS2 exposure class waterproof concrete (submerged constructions in a marine environment), the tanks were again injected on the ground with DRYflex acrylic resin, which waterproofed the joints and shrinkage cracks by pressure. We then proceeded to lift and launch by sinking.

The 4 tanks were then welded with a crowning casting. Also this joint, prepared with the DRYset injection channel, was waterproofed for its entire thickness with DRYflex resin. After emptying it was therefore possible to carry out the final testing.

The Drytech Tank as a whole, and the DRYflex resin in particular, must ensure impermeability from aggressive elements such as sea water.

Sant’Ambrogio car park, Milan

by
In Piazza Sant'Ambrogio in Milan, the company Borio Mangiarotti S.p.A. built a five-storey underground car park.

In Piazza Sant’Ambrogio, in Milan, the construction company Borio Mangiarotti S.p.A. built a five-storey underground car park.

Drytech has designed a waterproofing system for the diaphragm, based on Injectable Waterstop Tapes.

By making the diaphragm waterproof directly, it was not necessary to create the lining wall, thus increasing both the internal volume to comply with the legal limits, and the surface, or the parking spaces available.

The Injectable Waterstop Tape for the joints between the partitions of the diaphragms is a Drytech patent that makes it possible to maintain the joint with ex-post injections of resin, performed in the event of any infiltrations.

The Drytech tape is laid with a special sheet piling which acts as a formwork of the diaphragm wall.

The diaphragm of the parking lot that flanks the Milanese basilica drops to a depth of 22.70 meters and the laying of a sheet pile of this size required special care by the company’s technicians, to ensure perfect alignment of the joints.

At the end of the casting, the sheet pile is extracted, equipped with a new belt and repositioned for the casting of the next septum.

The re-injectability of the DRYflex resin guarantees the possibility of carrying out maintenance on the diaphragm at any time, by intervening from inside the structure, without excavation or demolition and, above all, without having to close the car park.
