Manhole / Catch Basin Repair

Over an extended period of time and due to high traffic and heavy loads of vehicles, concrete and bricks used in constructing catch basins and manholes begin to degrade, resulting in water penetration and cracked concrete or asphalt around them. If disregarded for long, this condition can worsen and may call for a complete resurfacing of your asphalt pavement.

The Main Infrastructure chimney replacement system uses a cutter-extractor to cut and remove the manhole frame from the road. First, a speed plate locks in to the frame of the manhole and allows the machine typically a skid loader or a backhoe that controls the cutter to be positioned at the appropriate points around the manhole frame. Attaching the cutter to a machine such as a skid loader generally uses a standard auger drive and requires no modification to the hydraulic system of the machine.

The cutting system has an adjustable cutting diameter of 28 in. up to 72 in. and can cut through asphalt and concrete. Cutting into asphalt on average takes less than 10 minutes but in concrete cutting can take anywhere from 10 to 20 minutes.
