Waterproof structure garage and cellars

by
The entrance to Residenza 27

Residenza 27 has two basement levels, built with the Drytech Tank waterproof structure in recycled waterproof concrete, which house the garage, technical rooms and cellars.

The Residenza 27 project was created to convert an obsolete residential area into a new energy-sustainable building, certified Minergie-P and built entirely with recycled concrete, offering apartments with a high level of living comfort.

Drytech also waterproofed the ramp and car park slabs, as well as the perimeter flashings of the house, with Drycoat waterproof architectural coating.

Waterproofing of surfaces

by
Exposed concrete villa

Waterproofing of surfaces with Drycoat architectural coating, which adheres like a second skin to the design of the pool and threshold along the entire façade.

The iconic villa designed by architect Mauro Galfetti stands out first and foremost for its perfect brutalist profile. Underneath the entire property is a waterproofed basement level with a complete Drytech Tank – floor, elevations and slab – which houses the underground floor of the first apartment, lit by a large patio parallel to the street, as well as the garage and technical rooms.

The Drytech waterproof concrete slab is the base of the garden.

The waterproof structure of the swimming pools is also a Drytech White Tank, whose above-ground surfaces have been coated with the continuous, waterproof Drycoat membrane which, with its 3 millimetres thickness, adapts like a second skin to the architectural lines.

In fact, it was also used to seamlessly waterproof the entire porch threshold and French window frames.

The granite flooring of the porch and the edge of the swimming pools was laid directly on the Drycoat membrane.

Waterproofing hypogeum and swimming pool

by
The swimming pool with sculpture.

The waterproofing of the inhabited hypogeum and swimming pool of a villa bordering a vineyard, set in terraces that continue seamlessly across the property. To adhere to this movement, the emerging volumes are staggered by half a floor: two transparent pavilions on which the living area is developed.

The basement, on the other hand, is the most private part of the villa, with rooms arranged around a large, spectacular courtyard, confirming the fusion between indoor and outdoor spaces.

Both the level of the bedrooms and the level below, which houses the main entrance and garage, are supported by the hillside. The soil, which is particularly impermeable, does not filter the water that presses directly against the basement. Therefore, the uncompromising impermeability of the Drytech tank was chosen for its construction, as well as for the swimming pool immersed in the lawn.

Waterproofing ramps and stairs

by
Staircase leading to the underpass at Torricella-Taverne station

Waterproofing of the new ramps and access stairs to the underpasses at the Taverne-Torricella and Balerna railway stations.

SBB has made five more railway stations south of the Alps more accessible by removing architectural barriers, modernising the furnishings and installing state-of-the-art passenger information systems.

Stairs and ramps were constructed using the Drytech Tank System: a structural approach to waterproofing concrete structures that guarantees long-term watertightness, thanks in part to its practical maintenance.

The existing underpasses have also been waterproofed.

In this case, with precise injections of expanding resin, which have repaired the concrete from infiltrations that had occurred over time.

Waterproofing of the underground car park

by
The façade of the school, characterised by perforated infill panels

Drytech waterproofed the underground car park beneath the new Lamone School.

The school design by architects Krausbeck Santagostino Margarido is deeply inspired by its context as well as its function.

Thus, the geometry of the school grounds harmoniously adapts to the surrounding buildings, aligning with the presence of trees and generating changes in the layout of the boundary wall.

The underground car park located beneath the school has 26 parking spaces. The foundation, which also includes the technical rooms, was built using the Drytech Tank waterproofing system, including the access ramp to the underground car park.

Waterproofing restorations of motorway tunnel

by
Entrance portal of the Vedeggio-Cassarate tunnel, at the Lugano Nord exit of the N2 motorway

Over the past three decades Drytech has carried out several waterproofing restorations of motorway tunnels on the Swiss N2 motorway, the main artery crossing the country from North to South.

The restoration system, based on expanding resin injections, sealed the seepages in cracks, joints and gravel nests.

Among others, Drytech has rehabilitated tunnels:

N2 Arisdorf tunnel – cracks, joints and gravel nests;

N2 Belchen tunnel, Dichten – passages, cracks and gravel nests;

N2 Hagnau Tunnel, Muttenz – passages and associated structures;

N2 Pratteln Tunnel, Liestal Schönthal – cracks, wall and ceiling joints;

N2 Lange Heid Tunnel, Münchenstein – movement joints;

N2 Dosso Taverne Tunnel – recess joints;

N2 Melide Grancia Tunnel – cracks and joints in the technical tunnel;

N2 Galleria Melide Grancia – cracks and joints in the summit part of the vault;

In addition, Drytech restored the portal of the Vedeggio Cassarate tunnel by sealing cracks.

Waterproofing buried podium

by
An architectural detail that alludes to the battlements of the ancient city walls and breaks up the composed monumentality of the building.

The waterproofing of the partially buried podium of the Torricella-Taverne school is made with a Drytech Tank.

The construction of the Torricella-Taverne nursery school is part of the overall reorganization of an area in which the construction of various public, scholastic and sporting works is planned.

The Celoria Architects studio has translated the constraint represented by an existing wall into a resource, which, by touching the individual elements present in the area, defines their mutual relationships.

The wall has in fact become the main subject of the intervention, constituting the base of the building and the site of the pedestrian walkway that leads to the school and connects to the sports fields via a ramp.

The three remaining sides of the podium are underground and house the technical and service rooms in a waterproof Drytech Tank structure.

The planimetric organization of the building interprets the functional indications relating to school buildings, with the aim of optimizing circulation spaces, reducing distribution to a minimum and eliminating corridors.

The abstract composition of the volume is however softened by the introduction of some elements somehow extraneous to this composed monumentality, which allude to ancient bastions characterizing their formal expression. 

Even if the final touch of tenderness to the Torricella-Taverne nursery school is given by the row of small colored scooters parked under the loggia.

Waterproofing underground tunnel

by
Cunicolo AIL Agno-Bioggio

Waterproofing with the Drytech Tank structure of an underground tunnel that runs alongside a river and at one point passes under the bed of a tributary.

The AIL Agno-Bioggio tunnel for high voltage systems runs alongside the Vedeggio river for 4 km and, in a central stretch, is also bordered by the Prati Maggiori canal. Precisely at this point the route of the structure crosses the Riale Roncaccio drainage canal.

To overcome it, the tunnel dives further below the riverbed up to -5 meters from the ground level. Due to the particularly delicate position exposed to multiple water pressures, this section of the tunnel was created with a total Drytech Tank: foundation, walls and slab.

The Drytech Tank structure of the AIL Agno-Bioggio tunnel has a thickness between 30 and 40 cm and the joints have been waterproofed with injections of DRYflex expanding resin.

By sealing the entire thickness of the joint, the resin also protects the reinforcing bars, because it keeps water completely outside the concrete. In the event of any infiltrations, the system provides practical and easily manageable maintenance from inside the structure, without interruptions to the service.

The real possibility of carrying out maintenance contributes to the main quality of waterproofing: which is to prevent water from entering for the entire life of the work, i.e. for 50 – 100 years in the case of civil engineering structures, as prescribed by SIA 272.
