Repair of manhole covers and grids
Common issues and queries you can face
Step by step solution
Break and cut 10cm around the manhole at a 90 degrees angle. Clean dust and other materials, remove traces of oil, grease, etc… by brush or air-blowing. Humidify the area where the mortar will be laid. It should be wet but not waterlogged.
weberep 314 RD must be used within 10 minutes (at 30ºC) from mixing. Re-mixing with an extra amount of water is not recommended. Apply weberep 314 RD on the substrate. The thickness under the frame should be at least 3 cm. Ideal application temperature is between + 5ºC and + 35ºC. If the application temperature is higher than 35ºC, make sure to use cool water to keep the mixed mortar temperature below 30ºC.
Fill the gap between the frame and the road with weberep 314 RD with a trowel. Then Finish with a float and level the mortar to road level, to have a perfect flat finish.
After application, protect the surface by using a curing compound like weberad cure WT or weberad cure Y 40 or by covering with properly secured plastic sheeting.
