Waterproofing rooftop swimming pool

The hanging pool and the lawn on the waterproof concrete slab of the Drytech White Tank

The waterproofing of a rooftop swimming pool can result in the bottom of the pool coinciding with the floor slab underneath.

This is the case of the scenic swimming pool at Villa Poiana on Lake Ceresio, built with the Drytech Tank waterproof structure.

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.

Waterproofing of tanks in wastewater treatment plants

by
The Rozzano wastewater treatment tanks of the Rozzano wastewater treatment plant are made of the waterproof structure Drytech White Tank.

The waterproofing of tanks in wastewater treatment plants presents a double challenge for watertight 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.

The waterproofing of the iconic fair-faced concrete roof pool, with its glass wall overlooking Lake Lugano, is the emblem of the Drytech Tank system.

Form and function coincide, just as the waterproof concrete structure corresponds exactly to the purity of lines of architect Edy Quaglia’s design.

The edges of the pool and the walkable areas are waterproofed with the continuous Drycoat, which adapts like a second skin to the surface.

Drytech realised the waterproofing of a rooftop swimming pool with the Drytech Tank waterproof concrete structure.

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.

Waterproofing of a residential complex in contact with the sea

by
The conversion of the industrial port area, west of the Genoa airport, also involves the construction of the Borgo alla Marina residential complex.

The Drytech Tank was chosen for the waterproofing of a large residential complex in direct contact with the sea.

When construction was complete, the waterproofing of the underwater level was tested by flooding the site perimeter.

After checking the watertightness of the Drytech Tank, the structure was launched by removing the sheet piling.

The conversion of the industrial port area, west of the Genoa airport, also involves the construction of the Borgo alla Marina residential complex.

200 prestigious apartments, with relative berths and garage, overlooking a new tourist port.

Below the buildings and the square, in direct contact with the sea water, is the covered parking area for residents.

Waterproofing the thermal plant

by
The residential center La Città sul Mare in Savona, in fact, heats up in winter and cools down in summer by exploiting the sea temperature.

The Drytech Tank waterproofing system was used for the sea inlet of the Città del Mare’s thermal plant, as well as for the two floors of the underground car park, which is exposed to a 5-metre water table, as can be seen from the jet pressure coming out of the pump shaft in the third picture.

The residential center La Città sul Mare in Savona, in fact, heats up in winter and cools down in summer by exploiting the sea temperature.

Excellent news for the sky arrives from the sea.

The plant is zero-emission and, using a renewable and free resource, provides a definitive solution to the problems of atmospheric pollution and the soaring costs of fossil energy sources.

The Savonate housing complex was built by Meraviglia Spa of Bulgarogrosso (CO) and was designed by the Technion Srl and Ellevi di Lecco design studios.

The 120 apartments are served by a heating system connected to a sea outlet, built on the boulder pier facing the complex.

The basic principle of the system is the substantially constant temperature of the sea water (about 18 ° in this stretch of coast).

The pipes of the heating and air conditioning system from the building run underground to the sea intake, where the heat pump is located, which uses sea water as a source or as a heat sink.

The transport of thermal energy takes place through the same water. Water that is sucked from the sea, brought up to the heat exchanger and, therefore, released.

The system has a positive energy balance: it supplies more energy (heat) than electricity needed for its operation (the ratio is at least 1 to 4 or higher, up to 1 to 6).
