MAURER Point Drainage The integrated bridge drainage in MAURER Modular Expansion Joints No standing water at the lowest point of the kerb unit No corrosion in the area of the kerb unit No additional maintenance efforts MAURER Modular Expansion Joints In Germany, the drainage of bridge structures is being ruled by the directive drawings issued by the Federal Institute of Roads. The maximum permissible distance between the drainage points is being ruled by the German Specification named ZTV-Ing, Part 8. According to the directive drawings named “RiZ Was 0”, the water which flows towards the end of the superstructure has to be drained latest before the end of the superstructure” With an integration of such a drainage into the modular expansion joint, a formation of puddles by way of accumulation of precipitation is averted in this area between the last drainage point and the expansion joint, which so far was very critical in respect of drainage. The water which was diverted by the slope of the carriageway to the lowest point of the expansion joint will be immediately and effectively forwarded into the drainage system of the bridge, and thus the traffic safety will be enhanced.

MAURER Point Drainage The integrated bridge drainage in MAURER Modular Expansion Joints Contrary to the finger joints, the drainage is being accomplished at a defined point. The watertightness of the expansion joint remains effective without any restrictions. Leakages in the area of the welded bends of edge and Finger joint Collection of dirt with spontaneous vegetation centre beams can be averted in designing curved bends instead of sharp bends in the steel profile. The constant curvature of the sealing element facilitates an unimpaired watertightness now also at these hitherto critical...
