Building On Raised Filled Rice Land.

[mhortig]

We recently purchased 250 talong wah of rice land and put fill dirt to raise it 1.5 meters. There is only rice land adjacent. so the land is like an island. Has anyone built on land like this? My first question is whether we actually need a wall to support the land before we build. We would prefer not to build a wall due to cost, but want the land to be stable enough to build on. The house will be 13 feet from the nearest edge and over 20 feet on the other sides. There is also a stretch of raised 15 foot wide access driveway. We will not surface the road until the construction is complete. If anyone has actualy built on raised filled land like this I would appreciate any information on what we should consider before building. Thanks

I would say yes you need a retaining wall, as once you start getting rain, the rasied ground will wash away, if you dont have a wall to keep it in place

How steeply is the edge of the fill sloped?

Provided it's not too steep there are alternatives to retaining walls, search for suitable deep rooted plants such as the Vetiver Grass promoted by His Majesty http://prvn.rdpb.go.th/king.html

You'll probably still need a low wall at the boundary to your neighbours, if only to stop their rice planting activities encroaching on your land.
