Masonry Tunnel Construction

Similar to standard masonry structures, masonry tunnels built with natural stone or brick can also be injected. The injection material is injected with the designated pressure through a grid of drill holes. The goal is to waterproof the water-bearing areas in the building element in order to later apply negative side waterproofing.

Hollow spaces behind masonry components require special attention. Here, many air-filled joints and large voids, which are more or less filled with water-saturated material (such as earth, sand, gravel, or rubble) are found. In many cases, it is important to ensure that no structural bonding with the surrounding rock layers takes place.
