Our offer includes the regulation of rain drains. If necessary, we replace the inlets with new ones. We start the adjustment process by raising the rainwater inlet to the level of the road surface, using appropriate tools. Clean the manhole and the gap under the flange with precision of any loose asphalt fragments, and then thoroughly moisten the construction elements. In the next step, pour the resulting gap with quick-setting mortar. The gaps between the body of the rain gully and the places around it, where the asphalt layer has been damaged in some way, are filled with a mineral-asphalt mixture and leveled to the level of the road surface. The time of one adjustment or replacement of the hatch is about 1 hour. After the time has elapsed, the built-in hatch can be loaded and traffic on the road can be restored.
