Bitumen waterproofing

Sealing is a matter of trust

Residential and commercial construction

We protect your home

In residential and commercial construction, one of our key tasks is to provide lasting protection for living spaces against damp and moisture. Bitumen waterproofing is one of the best ways to permanently protect buildings from these influences. It can also be used with all common thermal insulation materials. 

Our highly qualified employees in the bituminous waterproofing department at IAT GmbH ensure the necessary watertightness of buildings in all projects thanks to their many years of experience and continuous internal quality controls. 

Parking decks and garages

Park safely without worries

Waterproofing parking areas, parking decks and garages is one of our core competencies. Not only does it protect the structure from moisture and corrosion damage, it also prevents damage to the paintwork of vehicles parked there. Whether for new builds or rehabilitation, we have decades of experience and can offer the appropriate support right from the planning stage. 

Our customers often want a "Construction from a single source" solution.
With our in-house expertise, we are able to offer project services ranging from the removal of existing surfaces, rehabilitation, waterproofing and the application of the wear layer to floor marking. The benefit for our clients is that there are no complex interfaces and that the guarantee and warranty are provided by a single company.

Industrial construction

When functionality is key

Renowned industrial companies have been working successfully with us for years. They rely on our specialist knowledge and our management of complex work processes for large-scale projects. In particular, they greatly value the expertise of our team and the quality of our personalised advice. Trouble-free operation is essential, especially in the areas of production or with sensitive laboratory technology. We can guarantee this in every case as well as thanks to our expert consulting and the careful and timely execution of our sealing work. 

Structural engineering

We are the professionals

The waterproofing of engineering structures is a field for true specialists with expertise and years of experience – not only in new construction, but also in rehabilitation. Projects are becoming increasingly complex and place the highest demands on the quality of waterproofing. IAT GmbH is your expert for engineering structures such as underpasses and tunnels, both open as well as covered. 

Bridge building

Overcoming obstacles and ensuring stability

The challenge in bridge waterproofing is that it is not enough to simply be "watertight". This is because the high-quality waterproofing required essentially acts as a bridge between the supporting structure and the wearing course. 

A seal approximately 1 cm thick permanently bonds the various materials – concrete, epoxy resin, bitumen membrane and asphalt – together at temperatures ranging from -25° to +80° Celsius. Additional mechanical influences such as heavy lorries braking sharply or permanent transverse forces in motorway bends place immense strain on the permanent function. 

Through continuous quality control, the further development of laying techniques as well as the careful selection of suitable waterproofing systems, IAT GmbH also has the necessary technical expertise as well as decades of experience in implementation in the field of transport construction. 

Special seal

The business card in public spaces

Floors in car parks, industrial areas and communal areas in residential complexes are used and subjected to wear in different ways. They often look unattractive and sometimes even cause unpleasant odours, but as public spaces they should actually be the calling card of the entire complex. High-quality coatings should therefore meet the aesthetic requirements of users. 

We have the right solutions for this and offer all types of IO systems and corresponding systems with carrier inserts for crack bridging, as well as a wide range of design and configuration options. Sealing systems with liquid plastic or coating systems as chloride barriers, for example, are much more flexible and visually appealing than conventional wear layers made of moulded or Rolled asphalt. This allows for the creation of pleasant and bright surfaces that are also easier to clean.
