Drytech Tank
The Drytech Tank is the structural waterproofing
for underground constructions, in groundwater or in contact with liquids.
It is a single structure in waterproof concrete
with the construction details sealed by expanding acrylic resin.
The entire surface and entire thickness of the structure are waterproof.
Construction is quick and beneficial for the whole site.
Waterproofing is integral, solid and guaranteed.
The Drytech Tank guarantees:
- the tightness of the structural waterproofing, which opposes the ingress water and radon creating a barrier equal to the thickness of the structure itself;
- the saving of time and related costs for the entire construction site, easily quantified with the cancellation the waterproofing item from the Gantt chart;
- the security of the Drytech Engineering’s continuous consultancy to the designer and the construction company;
- the real possibility of maintenance of the below grade structure, for the entire life cycle of the building.
DRYTECH waterproof CONCRETE
Drytech Engineering creates the tailored mix design for the specific construction
based on the characteristics of the concrete plant chosen by the client.
Drytech concrete has two characteristics: it prevents the penetration of water and reduces the formation of cracks.
Cracking is an inevitable phenomenon of maturation, but the Drytech Tank manages and controls it.
The Drytech Recipe is aimed at obtaining a progressively maturing concrete that, in combination with the DRYset cracking elements, tends to avoid the formation of random cracks.
Drytech Engineering adapts the formula to the characteristics of the concrete plant chosen by the customer, without additional costs and without additives.
Drytech performs quality checks at the concrete plant, on site and in the laboratory, to transfer all the waterproof qualities defined in the formula specific to the structure.

Watertight details
Structural details are waterproofed by injecting DRYflex Expanding Resin, which seals joints, penetrations and cracks throughout the entire thickness, creating a barrier against water that is as thick as the structure itself.
The components of the DRYset system prepare the details for the injection of the waterproofing resin, ensuring its rapid and thorough diffusion.
DRYset ducts, sleeves and crack inducers are installed by Drytech technicians without affecting the work schedule and regardless of the weather, as DRYset components are made from materials that do not react to water.
The Drytech Tank controls shrinkage cracking, making the site’s daily output potentially unlimited.
Shrinkage cracking is, in fact, planned, induced and controlled using DRYset Cracking Inducers.
CIs replace the cold joints in the floor slab and drastically reduce those in the walls, speeding up the construction of the basement, with benefits for the entire building site.
CI can also be used as permanent formwork, offering further savings in terms of time and cost.
The positioning of the crack-inducing devices is designed by Drytech Engineering, and their installation – carried out by Drytech technicians – is not affected by the weather and takes place in parallel with other activities on site.
Once the concrete has set, the cracks caused by the CI are sealed throughout the entire thickness of the foundation slab and walls by injecting DRYflex resin.
The DRYset sleeve ensures that the waterproofing resin spreads rapidly and evenly through the penetration, enveloping the penetrating element and sealing it throughout the entire thickness of the structure.
The installation of the sleeve is not affected by the weather and takes place alongside other activities on site.
The system is suitable for penetations of any type and size.
The DRYset Waterproof Pump Well enables construction companies to create drainage points within the foundation slab.
Once it has served its purpose, the DRYset pump well is embedded in the foundation slab and waterproofed both externally and internally:
> the outer surface of the shaft, where it comes into contact with the concrete foundation slab, is injected with DRYflex expanding resin, which seals the structure throughout its entire thickness.
> the interior of the shaft is sealed by a cover fitted with gaskets both around the circumference of the shaft and on each of the locking bolts.
The DRYset Waterproof Pump Well can be fitted with a cover incorporating a gate valve, making it accessible for inspection, and a pressure gauge to monitor the groundwater pressure.
Construction joints are waterproofed throughout their entire thickness by injecting expanding resin. By completely sealing the joint, the structure’s integral watertight integrity is maintained.
The water remains completely outside the structure, so that the waterproofing also protects the external reinforcing bars.
The DRYset channel ensures that the joint allows for the rapid and widespread diffusion of the waterproofing resin.
The system is suitable for cold joints of any type and size.
The installation is not affected by the weather and runs in parallel with the other activities on site.
Movement joints are waterproofed using DRYset Injectable Waterstop Tapes.
As well as extending the water’s path, DRYset Waterstops allow the movement joint to be completely filled with DRYflex expanding resin, which spreads through micro-perforated channels integrated into the tape.
Any maintenance re-injections are simple and non-invasive.
The system is suitable for expansion joints of any size, both internal and external.
Waterproofing the diaphragm eliminates the need for waterproof lining walls.
Partitions can be made watertight directly by inserting DRYset Injectable Waterstop Bands into the joints between the partitions.
It is a solution that is used, for example, in basements where the available space must be utilised to the full, whether for regulatory or economic reasons.
The special DRYset Waterstop Bands for diaphragm walls are fitted with micro-perforated tubes – accessible from inside the structure – for injecting DRYflex expanding resin throughout the entire thickness of the joint.
Furthermore, the system allows for maintenance reinjections in the event of any leaks.
The formwork holes are sealed by inserting a press-fit plug and applying DRYpox epoxy resin.
dryflex resin
waterproofing resin
DRYflex Expanding Resin seals construction joints under pressure.
The waterproofing of the joints matches the thickness of the concrete perfectly, forming a structural barrier against water.
At the time of injection, the two-component acrylic resin is as liquid as water: it therefore perfectly fills all the voids it encounters, from micro-cracks to gravel pockets.
DRYflex then cures, transforming into an expanding gel that provides a watertight seal for joints, penetrations and cracks.
DRYflex resin is injected once the concrete has set, from inside the structure.
The injection process is independent of other site activities and the weather, and remains effective even in the presence of pressurised water.
The effectiveness of the injection – that is, the sealing of the structural detail – can be verified immediately by visual inspection, and the elasticity of the resin allows for any re-injections.
DRYflex is solvent-free and, in its standard formulations, has no adverse effect on the environment.
It is therefore also used in the drinking water sector.
It is also resistant to aggressive liquids and chemicals.
The final polymerised product can be disposed of in the incinerator as household waste.
According to current European transport regulations, resin is not classified as a dangerous substance.

MAINTENANCE
Would you buy a car whose wheel cannot be replaced in the event of a puncture? A waterproofing system that does not provide or, worse, does not allow maintenance is like a disposable car. Indeed, the entire building becomes a disposable one. The Drytech Tank not only allows maintenance: it makes it practicable quickly and minimally invasive. Not only the wheel can be replaced: it can be done while the car is in motion, without interrupting the journey.
Out of metaphor, the theme of the maintainability of any waterproofing system is as fundamental as it is underestimated. Theoretically, any system works. In the real world there are unexpected events – very predictable – and the wear and tear of time.
The need and method of a maintenance system is sanctioned by the SIA Standard 260 : 2013:
2.3.4 Waterproofing: Underground structures inaccessible once the works are completed.
It’a mandatory to choose Waterproofing systems that allow maintenance from the internal side of the structure.
The ratio between the waterproofing cost must be 1 : <1 (for example: waterproofing 1000 : maintenance <1000).
The Drytech Tank always allows the waterproofing to be restored, through practical injections of DRYflex expansive resin from the inside of the work.
Being a single structure, in the Drytech Tank the cause and effect of any infiltrations coincide, so the intervention is timely and immediately verifiable with the naked eye. And it does not require the suspension of the building’s activities. Also for this reason Drytech maintenance systems are also used in the restoration of any other type of waterproofing.
Many systems offer waterproofing of the structure. But it is only the maintenance – actually practicable and non-invasive – that guarantees impermeability over time.
