Etschwerke AEW Bolzano Inspection Tunnel

Originally, a simple sealing was intended, but due to a void beneath the concrete layer, it had to be removed, the hole deepened, fitted with connecting rods and hoses, foamed, and sealed with a sealing cord, utilizing special IPA products.

Initially, the task was a simple sealing. However, as there was a hollow space beneath the first concrete layer, a section had to be chiseled away. Blackened soil was found underneath.

Consequently, the scope of work changed. First, the hole was opened to a depth of approximately 40 cm. This was followed by the insertion of connecting rods, the placement of hoses for subsequent foaming, and the pouring of concrete into the affected section. To ensure absolute watertightness, a sealing cord was installed.

The following IPA products were used in this exceptional project:

IPAPUR VM 1K and IPAPUR VM 2K

IPANEX Plugging Mortar

IPA Cordless Injection Pump.
