Waterproofing of the underground car park

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 Vasca Drytech waterproofing system, including the access ramp to the underground car park.

Waterproofing of a shopping centre basement levels, using Drytech Tank waterproof concrete structure (BS8102).

The Kells Project is a flagship development in the heart of Dublin city centre, involving the construction of a brand new office complex with a floor area of over 22,000 m².

Rarely are basement projects more challenging, larger or deeper than those in the Kells project. Drytech is proud to have participated in the waterproofing strategy for such an important project, working to the highest standards of engineering and contracting.

Using the Drytech White Tank system, we designed, installed, built and guaranteed the waterproofing of the entire basement, together with other talented teams of Irish contractors and designers.

Waterproofing restorations of motorway tunnel

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 of the underground car park of a data bunker

One of the servers hosted in the bunker in the Swiss Alps

The waterproofing of the underground car park of a data bunker in the Swiss Alps was carried out in the water table with the Drytech Tank system.

The Swiss army’s underground bunker is used by MOUNT10 to transfer data fully automatically and encrypted.

Security systems are constantly being updated in order to protect client companies from the consequences of data loss, theft and modification.

Today, thousands of SMEs in Switzerland also benefit from the services offered by the Zug-based company MOUNT10 and its back-up servers deep in the Bernese Alps.

Water tank waterproofing

by
Drytech has built the new 5,600 m³ water tank, which will feed the cannons for artificial snow Close to the Carosello 3000 station in Livigno, with the Drytech White Tank Waterproofing.

Drytech built the new 5,600 m3 water tank, which will supply the snowmaking cannons at the Carosello 3000 resort in Livigno, with the Drytech Tank waterproofing system.

The work, built in 5 months with a 2’175 m² Drytech Tank, is completely underground to have no impact on the Alpine panorama.

The practicality of the construction of the Drytech Tank makes the construction of these structures faster.

Time is a decisive factor in any construction site, but it becomes even more important for applications conditioned by seasonality (the structure had to be ready in time for the opening of the ski season) and with a climate that reduces the useful building time to a few months.

Drytech Engineering has formulated a waterproof concrete suitable for environmental conditions, based on the characteristics of the aggregates present in the plant chosen by the Edil Dona company in Valdisotto, Sondrio.

The acrylic resin DRYflex, which waterproofs the details by pressure, is certified for use in structures in contact with drinking water, so it is safe for the environment and therefore perfectly suitable for use in a tank that feeds the guns of snow.

One of the main acceleration factors on the construction site is the control of shrinkage cracking.
In fact, the Drytech tank allows you to make continuous castings (the bed was cast in a single solution) because the cracks are induced by the Cracking Elements, which can also act as disposable formwork.

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.

Restoration waterproofing of a road tunnel

by
Drytech vehicles near the service tunnel entrance

Restoration waterproofing of a road tunnel service tunnel affected by seepage and mould, with DRYflex resin sealant injections from inside the structure.

The tunnel originally provided access to a Cold War bunker, built between 1969 and 1971. It was later converted into an escape tunnel from the road tunnel.

In order to restore it, all electrical components were dismantled. and then moss and mould were removed to expose the wall and identify exactly where water was seeping in.

Drytech technicians then carried out crack sealing injections, sealing the tunnel vault and walls.

The intervention was carried out between 8pm and 4.30am to minimise the impact on tunnel traffic.
