Overlooking Lake Maggiore, immersed in the woods above Ascona, the house with a hanging pool designed and designed by engineer Bonalumi for himself.
The pool occupies part of the top floor and, from the water, the view sweeps across the entire lake.
The bottom of the pool is the slab of the master bedroom.
The structure is a Drytech Tank in exposed waterproof concrete, with the edge of the pool completely covered with the Drycoat waterproof covering.

An industrial clarifier receives wastewater laden with metals, hydrocarbons and other pollutants.
It separates these elements from water through mechanical and chemical processes.
It then conveys the clarified water to the sewage systems and retains the residual sludge from the purification.
The walls of a clarifier are therefore exposed to a series of more or less aggressive agents. Conversely, they must not release any material into the water, much less polluting.
The DRYflex resin – used to seal joints, crossings and cracks in the Drytech Tank – has this dual ability to resist aggressive agents (starting with salinity) and even be compatible with use in drinking water facilities.
It is important to emphasize that the resin saturates joints, cracks and crossings for the entire thickness of the structure.
In the case of the Genoa clarifier, the barrier opposite the water has a variable thickness from 30 to 120 cm, coinciding precisely with that of the structure.
On the other hand, the characteristic single structure of the Drytech tank allows direct and non-invasive access for any maintenance interventions, which are simple and immediately verifiable.
Moreover, without particular limitations on the use of the system.
As part of the construction of the Genoa plant, Drytech Engineering collaborated with the structural engineer already in the design phase, proposing solutions for waterproofing the critical points of the structure. Engineering also contributed to the definition of the recipe for controlled shrinkage waterproof concrete, based on the characteristics of the plant chosen by the client.

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.

There are only two ways to build a waterproof structure directly in water: either the classic double tank, or the single tank of the Drytech Tank technology.
The undergrounds of the Villa Branca Residence in Melide, on the banks of the Ceresio, were built with this system.
A luxurious crescent consisting of 16 apartments and 5 penthouses, with terraces, roof gardens, whirlpools and parking below the lake level.
In addition to allowing underwater installation, the Drytech tank ensured compliance with the internal volumes envisaged in the project, being a single waterproof concrete structure.
Drytech Engineering has defined the recipe for waterproof underwater concrete. As the casting matured, the construction details were waterproofed with the injection of DRYflex resin, effective despite the presence of water outside the new tanks.

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.

Hilton Lake is the largest hotel on Como Lake.
Opened in 2018, it has 170 rooms, two restaurants, a spa with indoor pool, a state-of-the-art fitness center open 24 hours a day and a conference area divided into 6 modular spaces and a total capacity of 300 seats.
On the elegant rooftop on the top floor of the building, guests can enjoy the breathtaking view of the lake directly from an infinity pool – created by Drytech in a single waterproof concrete structure -, from the adjacent lounge bar with terrace overlooking the city gulf. or, on the opposite side, from the solarium with hydromassage.
The project by architects Dario Pietro Cazzaniga and Monica Limonta started with the redevelopment and renovation of two existing buildings: a former brick weaving house, which houses the entrance, reception and lounge bar Taffeta, and a rear body that has been completely redesigned on the large floor-to-ceiling windows of the rooms.
The two main bodies are connected by a modern glass structure that houses the lobby and reinterprets the lakeside tradition of greenhouses and winter gardens.
The whole structure, including the 21 suites, was furnished by the architects Cazzaniga and Limonta.
A global approach that is reflected in the elegant architectural and functional unity of the project and which places the structure at the top of the Lake Como hôtellerie.

The Bresso Niguarda treatment plant was equipped with a new denitrification basin of 10,800 m³.
Wastewater denitrification is a process for the removal of nitrogenous compounds present in solution by optionally heterotrophic bacteria.
The part of the plant where the process takes place is a rectangular tank divided into two chambers of equal size, connected only superficially, which allow the continuity of the treatment, even when one of them needs to be emptied for maintenance.
Being a single waterproof concrete structure, the Drytech tank has the advantage of allowing maintenance interventions carried out from inside the tanks and immediately verifiable.

The architecture of Villa Poiana frames different views of the panorama offered by this corner of the Ceresio, transforming them into as many spectacular views.
In particular with the exposed concrete beams that define the patios on the first and second levels of the villa.
The building designed by the architect Mischa Groh is composed of two superimposed bodies, rotated by 30 degrees relative to each other.
The slabs are connected to each other alternately on the right and left side, drawing the facade as a schematic Z.
The large à jour windows are set back from the front of the facade. In addition to guaranteeing comfortable shade to the interiors at the zenith hours, this solution enhances the powerful design of the villa through the contrast between light and dark.
The façade is in exposed concrete, made with formworks composed of narrow boards that ripple the surface, producing a warm material effect.
The roof of the lower body is the base of the lawn of the upper villa, in which the scenographic hanging swimming pool built with the Drytech tank is immersed.
For swimming pool structures in contact with chlorine or salt water, Drytech has developed a specific concrete recipe that resists aggressive agents.
The structure of Villa Poiana follows the slope in which it is set, so all the walls of the shafts on the side of the rock were made with Drytech Waterproof Concrete and with the waterproofing of the details with Drycoat flaps, the elastic and continuous waterproof covering that adheres and adapts to the structure like a second skin.

Water treatment tanks represent a double challenge for waterproofing systems.
This type of structure must in fact guarantee double impermeability: to the external water table and, obviously, to the water treated inside the tank.
The Rozzano Purification Plant is also located on a narrow strip of land between the southern course of the Lambro river on one side and a canal on the other, in the south-east area of the Smeraldino Oasis.
So the theme of the watertightness of the work is, if possible, even more sensitive due to the environmental implications.
Made by the Intesa Costruzioni company in collaboration with Drytech, the new purification tank was built in just 120 days with the Drytech Tank system.
The waterproof concrete was formulated by Drytech Engineering based on the characteristics of the system chosen by the construction company, with the aim of ensuring, in addition to watertightness, chemical resistance to urban waste.
Similar resistance is obviously required for DRYflex resin, which, being expanding, waterproofs joints, cracks and crossings by pressure.
The resin is injected along the entire thickness of the structure, so it opposes the water with a corresponding barrier.
Furthermore, the compatibility of DRYflex with drinking water – certified by compliance with BS 6920-1: 2000 – allows for guaranteed use in structures in contact with drinking water.
The new tank of the Rozzano Purification Plant, which came into operation in February 2019, has a capacity of 1,700 m³ and treats a maximum flow rate of 360 m³ / h.
