Water came up while doing excavation work for a road
Water came up while doing excavation work for a road
(OP)
we found water while doing excavation work for the road's subgrade.
The water seems running through sand and smaller rocks as we found them.
the contractor suggests to pump out the water and remove all the saturated materials and put 2-3' of clay at once.
I think that might create a weak lift and might have negative impact on the road in the future. (Winter here is 40 blow)
Any suggestions?
Thanks.

I think what we will do is that leave it over night...if it is underground water, we will lower the watertable 2-3', and re-work the subgrade as usual.
If the water come up the next, which means it is actually a spring....i guess we will have to install some sort of drainage, and re-direct it.
Any other suggestions?

There are a few limitations...the most important being good fall to an outfall location.......the water has to have a place to go.
They work great, and have been used in this area for decades.
Trench is bedded w/aggr., perf pipe (encompassed in filter fabric) placed, more aggr. placed around perf pipe, then the last foot or so is backfilled with subgrade material.
