Lowering gutters serve to drain off rainwater and are mainly used in road and path construction. They are also used for the edging of liquid-tight surfaces at fueling and washing stations to help protect the environment. Moreover, drop gutters ensure fast and safe driving over.

At the service station in the Spreewald, in the truck fueling area, loosened lowering stones needed to be removed, cleaned and newly fit in. To ensure that the lowering stones cope exactly in height with the FD concrete (liquid-tight concrete), they were laid in a mortar bed using Rapid Set MORTAR MIX.

Besides the exact height level, the duration of work was crucial. A reason more to opt for the high-performance MORTAR MIX fast-setting repair mortar. On workdays the service station is highly frequented by trucks and agricultural vehicles, thus the necessary renovation could only be carried out on a weekend. The Rapid Set fast-setting mortar offers the benefit that it is ready for full traffic stress already 1-2 hours after installation.
Also the final joint filling with liquid-tight bitumen compound could be carried out immediately without long waiting time.
