Silt

[nattasit]

Hello, I am currently involved in a jetty construction in Thailand. We are having quite a bit of silt needed to be disposed of (silt area covers around 8 ac). Local regulations make it impossible to just dump it in the ocean and we might not have enough room to keep it onsite.

Does anybody know if any industry do need silt? Or if we can make use of it somewhere in the construction process?

Thank you in advance.

might be useful for capping a nearby landfill, provided it meets the low permeability requirements

Silt is quality fill if placed at optimum moisture in thin lifts with sheepsfoot compaction. Works good for embankments and structural fill under foundations. Needs protection from flowing water.

just goes to show, it depends...
around here silt is rarely considered a quality fill for any purpose.

 

[msucog]

it depends on the geology, material properties and intended use...'round here it works just fine for structural fill under most circumstances.

There is "quality" fill and "useable" or "okay" fill.

thankyou bigh, you hit it on the head. with extremely tight moisture control and compaction effort, you might get OK compaction.

i know graders that prefer the "red stuff" (carolina silts) over other soils because the sheepsfoot gives a good indication of compaction.... But when it's over optimum mc, it's the tester's fault.

I have not had any luck getting compaction with silt. If the silt you are trying to get rid of is sandy and would appear to drain well I would look for golf courses or sports fields in construction or maybe check to see if either is doing sod plots they could use the material for.

Depends on the silt... One concern is why do you have 8 acres of silt? Is there degradation of the land upstream, like cleared for farming?

That's where silt goes, eventually, the ocean... The question might be posed "how far out" vs. "can we".
