harrywegHello,
I want to install a 1.80 m (6 ft) high privacy fence. Unfortunately, I am unable to drive ground spike sleeves into the soil on my neighbor’s side. They twist during installation and cannot be driven in any further once they become misaligned. If you pull the sleeve out again, it is bent.
At this location, my neighbor has a paved car parking space on their property. The base layer (compacted gravel/scree) appears to extend a few centimeters onto my property.
My idea was to rent a motorized earth auger to drill the holes, then fill the hole with concrete and use 91 mm (3.6 inch) U-shaped post anchors. These anchors have only about a 14 cm (5.5 inch) welded steel piece that can be embedded in concrete. Would that be sufficient to support a 1.80 m (6 ft) privacy fence?
Most importantly: Would such an auger even be able to penetrate this ground where there is some gravel? If using the auger works, would holes 60 cm (24 inches) deep and approximately 15 cm (6 inches) in diameter be enough?
As an alternative, I was told it might be possible to install a footing about 30x30 cm (12x12 inch) and 40 cm (16 inch) deep by digging with a spade, mattock, and shovel. The size of the footing seems a bit small to me, or maybe it’s not deep enough. In any case, the post anchor could not be centered because I need to stay on my side of the property. So, there would not be much concrete surrounding the post toward the neighbor’s side.
Please share your assessment or any suggestions.

I would set H-post anchors into a concrete footing. You should be able to install the footing next to your neighbor’s driveway as well. You may need to chip away any irregularities in their base.
Take a photo and, even better, a sketch of the ground (a cross-section along the boundary line).

Hello, the H-shaped post base would need to be installed right up to the property boundary and would therefore be surrounded by concrete on only three sides. A U-shaped bracket would have been more suitable here because the beam is in the middle of the post and would thus be fully enclosed by concrete. With the H-shaped post base, I would need to extend the foundation underground onto the neighbor’s property.
How far is the parking space from your plot? Is there anything between the curb and your property?
When working on our fence, I also had to dig through gravel in some parts. Using a long chisel made it a tough but manageable job. Next time, I would rent a rotary hammer! I have 100cm (40 inches) posts with 60cm (24 inches) buried in the ground, of which about 50cm (20 inches) are set in concrete. For a 1.80m (6 feet) fence, I wouldn’t go with less—if anything, I’d go deeper!

There are earth augers available for this purpose. You can drill a hole, for example, with a diameter of 110mm (4.3 inches), insert a 1kg (2.2 lbs) pipe, for example, with a diameter of 100mm (3.9 inches), and fill the inside of the pipe with concrete plus the anchor. Allow it to dry completely before installation.
