Watertight sealing of concrete in infrastructure and civil engineering construction

In the construction of roads, car parks, stadiums and other concrete structures, joints and the sealing materials used play a crucial role. These joints not only provide a liquid-tight seal that keeps the underlying structural elements dry, but also help extend the overall service life of the structure. Sealing the joints in a durable manner significantly reduces the risk of cracking in the concrete.

Watertight joint sealing: essential for durable concrete structures

Concrete structures contain expansion joints to absorb movement caused by thermal effects and loading, and to prevent uncontrolled cracking during the curing process. Sealing these joints in a correct and durable manner creates a liquid-tight structure. This protects the structure against leakage and reduces the risk of cracking.

Selecting the right sealing system is crucial, especially given the variety of loads to which concrete structures are exposed, such as temperature fluctuations, traffic loads, UV radiation and possibly chemical influences. SABA offers high-quality sealing systems that ensure a reliable seal and thereby contribute to a durable and stable structure. Depending on the requirements and conditions, the most suitable system is selected in consultation with you to ensure long-term performance.

In addition to watertight joint sealing, SABA also offers solutions for concrete repair, prefabricated connections and smoke and fire protection. Feel free to contact us for tailored advice.

Liquid-proof assurance for precast concrete structures

Precast concrete elements are assembled on site to form complete structures, such as car parks and stadium grandstands. These structures often feature large spans and are exposed to additional dynamic loads, for example from moving traffic or moving crowds.

The joints between precast elements are critical points where a durable, liquid-tight seal is essential to prevent leakage and damage. SABA offers high-quality sealing systems for this purpose, such as the SABA Sealflex system, which effortlessly accommodates movements of up to 30 mm and thereby contributes to long-term structural reliability.
