Excavating Barn Floor & Concreting

On this project the client required us to concrete the floor of this barn conversion. We had to remove the existing concrete floor, stone flags, stone kerbs & concrete buskins. We used a small excavator with a pecker attachment to break up the concrete floor. The waste material was removed to a waste processing site to be recycled in crushed hardcore. The barn conversion is constructed on solid rock. Once the concrete floor had been removed we had to reduce the floor level. The concrete floor was laid on bed rock, so the pecker was used to remove the bed rock.

This barn was constructed in 1768 this room had been used as the farm dairy. It had pre-cast buskins installed for milking. Drainage channels running out the door. The stone kerbs & stone flags had been laid on lime mortar.

The small micro excavator made it easy to excavate the floor area. With the attachment of a concrete pecker, the concrete floor was not a problem.

We removed the blockwork from the windows to allow the fumes from the excavator to escape the barn.

We removed the broken up concrete to a skip located in the car park. All the concrete had to be wheel barrowed out of the barn, down a steep slope, across the yard area & over the road.

We removed a total of 30 tons of rock & concrete from the barn. The broken up concrete was sent for recycling. A crusher was used to break down the concrete & rock.

The pecker attachment on the small excavator made removing the concrete shippon floor very easy. The concrete floor had been laid on the original bedrock excavated. The use of a small digger is ideal when digging out floors on barns or other building. Our contractors took just 2 days to remove all the concrete floor and concrete buskins from the barn.

All the original flag stones and stone kerbs were removed and stored outside for re-use in other areas of the barn conversion.

We have upload a video of the micro excavator pecking out the concrete floor of the barn conversion. This short video is to give you a in site into the work involved on a construction site.

Once all the concrete floor had been broke up with the hydraulic pecker, we put on the excavator bucket and loaded the concrete.

Once all the concrete was removed we had to reduce dig the barn floor. We found the concrete was laid on the original bedrock. So we used the hydraulic pecker again to break up the rock. Once we had reached the correct depth we removed the broken up rock.

We located a manhole previously installed by another contractor. There was a number of foul & waste water drains to install under the floor of the barn before it was concreted.

Once the manhole was found on of our groundwork's excavated around the manhole chamber to clear the inlets. The inlets in the manhole had plastic stoppers installed to prevent spoil ingress. The ground around the site was very rocky which made excavating difficult.

Here we are excavating the trench for the foul pipe. This photo was taken to demonstrate how the small excavator could work within a narrow doorway. We used a 6'' bucket to excavate the trench but due to the rocky ground conditions the trench ended up being 12" wide.

To the left and right of the digger you can see the stone flags and stone kerbs we removed from the barn conversion.

When the trench for the waste water pipe was excavated we install a 4" plastic waste pipe.

We have uploaded a video to You Tube to show how the small CAT 300.9d can work in small places. We are operating it in a narrow doorway with limited space.
