Large mound on lawn

zaphod2007 · 03-02-2015 3:22pm #1

Myself and the wife have been househunting for a few months and we've now found a place that's as near perfect for our needs as we are going to get. Quite a long back garden, too, which is a nice bonus.

Half way down the garden there is a large, hard mound, about 3 ft wide, 1.5 ft high. I thought nothing of this until a friend suggested that it could indicate a flood risk. An underground river flooding and pushing the soil up. There is an underground river in the area, but from the info I can gather online, it doesn't appear to go directly under the property.

Anyone got any experience or thoughts on this kind of thing? Thanks

Can't help, sorry, but curious as to where you want to get details of the underground river?

Could it be a covered tree stump that the owners didnt bother grinding out?

I live near an underground - culverted - river, and there's no associated raising of the ground. I can't see how it could create that lump without it slumping again?

probably just a load of soil that was pushed into a mound and left there either on purpose ( i know someone who did this, the kids liked running down it) or when they were clean the garden and it was easier then taking it away

I had one almost that size in my garden when we moved in - wasn't until I stuck a spade in it and saw zillions of ants coming out that I realised it was an ant hill....
