Fin drains for land drainage

[adamr7747]

Hi All,

 

I have a site with a gentle slope across it & my (to-be) house in the middle. When it's wet the water runs onto and across the site from neighbouring fields. The groundwater level is also generally only just below the ground level. So I am looking to divert away the flow on the surface & in the ground.

 

I've read the page on pavingexpert on fin drains and think it looks like exactly what I need - does surface & subsurface drainage. Doesn't require messing with lots of aggregate and minimises the amount of digging. The only catch is I can't really find anywhere that sells them for domestic use. It's all about roads. Is that because I'm missing something which makes them obviously inappropriate? Or does anyone know a good source for them online? Or should I be looking somewhere else?

 

Thanks,
Adam
