Does anyone have come across a situation whereby the Geogrid retaining wall which has already built in my case approx 4.0m high(13.0 ft) & afterwards Noise fence contractor comes & want to built their structure using vacuum excavation method.
I am concerned they would damage the polyester geogrid and hence the wall stability. The hole size they want to augur is about 0.75m for fence post about 0.61m dia & 4.0m deep terminating just approx close to base of retaining wall. The fence is about 12.0 ft high.
I am worried it may apply additional loading on to my wall. The wall was not designed to take any lateral & vertical loading from fence structure. In terms of vertical load i sense it should not be a problem since they plan to take post all the way down to base of retaining wall.
I am also worried about local geogrid pull out failure at the fence post location. The center of the fence post is approx 1.0m from back of cap block.
We have used large size machine placed modular blocks for retaining wall construction
