Advantages

Speed and simplicity of implementation
Leak-proofing option using elastomer joints
Fitted under road surface, with upper surface flush with the ground
(directly receives traffic loads without load-spreading slab)
Economical solution

They are generally fitted on a thin concrete raft foundation.
The nature and compacting of lateral ballast is to be defined by the main contractor, according to conditions of use.

 

Dalot principle allows construction of :

Service ducts
Hydraulic structures
Sanitation structures
Underpasses
