Rising land prices mean that sites have to be optimally used. For this reason, innercity buildings are growing not just upward, but also down into the ground. This is increasing the need to seal foundations and underground floors against moisture and dampness. Sika has developed a new waterproofing membrane specifically for this rapidly growing market. It can be applied more easily, and thereby contributes to increased efficiency in building projects.

Speeding up Underground Work

Construction below ground is becoming more common in major cities. Foundations are increasingly being sunk beyond groundwater level, with the space gained being used not just for underground garages, but also for offices, shops, as well as leisure and sporting facilities. In addition, developers are insisting on ever swifter and more cost-efficient construction. Sika has the perfect solution for these requirements with SikaProof® A+. The latest generation of fresh concrete bonded membranes offers maximum protection against moisture. It can be applied both before the concreting process, and afterward to freshly molded concrete surfaces. This reduces the coordination workload and significantly accelerates construction site processes. The ease with which membranes can be applied also helps to manage the shortage of skilled labor.

The SikaProof A+ membrane results in significant time savings. It can be applied to concrete walls retrospectively, therefore eliminating the need for time-consuming application at the concrete framework stage.

The additional production capacity at the new facility in Sarnen makes it possible to satisfy rapidly growing demand for the innovative SikaProof A+ membrane. No other segment in the market for waterproofing systems is growing more rapidly than that for fresh concrete bonded membranes.

The application of the new sealing membrane saves a considerable amount of time.

Our new waterproofing membranes can also be applied to walls after the concreting process. This accelerates the construction process and opens up new growth potential for us." Philipp Irniger Corporate Target Market Manager Waterproofing
