Spring water drainage - How to stop spring water invading garden

[himandme]

I have a problem with my neighbours spring. Their bungalow is at the side of my property and about 18 inches higher. We are having trouble, not with surface water, but water coming up. We didn't have much of a problem previously, but they have just dug up three weeping willows, and since then we have had a constant drizzle of water. I have built a retaining wall, but the area behind this is now full of water, and water has broken through two areas along my path. We are not on main drainage for surface water. I am more than a bit worried that this continuous drizzle of water will undermine the foundations of our house. Any ideas on how to resolve this problem. The retaining wall is about three feet away from the house (the width of the path, and about six inches of gravel against the house wall) Thanks. ???

a picture would help but it sounds like a job for a structural engineer ,a party wall surveyor and maybe a solicitor
where roughly are you in the south east?

Massively thirsty plants, they were probably just putting off the inevitable.

i spoke to a surveyor today and he said you need to speak to your local building control officer firstly and then environmental health
he said it takes 14 years for ground to recover when weeping willows are dug out
you could potentially suffer from heave depending on your subsoil
he said keep a log with photos of any instance when you get flooding in your garden
so local BCO first
then enviromental health
