Grout curtain
Grout curtain
(OP)
Does anybody have experience using grout curtains to stop the flow of water through a temporary sheet pile wall?
I have to design the sheet pile wall to support submerged FILL. Since there are many buildings around the excavation I am concerned that settlement will occur. I can adjust the strutting combinations to reduce the settlement associated with wall displacement. I am not sure if a grout curtain will prevent fines from seeping through the wall (interlocked sheetpiles or pipe piles).
Is it just an expensive luxury or will it work?
Thanx

RE: Grout curtain
You might look at using sealed Joints on your sheet piling wall, this method will provide sealed connecting joints between adjacent sections of in-ground sheet piling that forms a continuous barrier, which will minimize the migration of ground water and other liquids through this System. Please take a look at the provided link, and feel free to contacted me at any time for more detailed information.

1. If the piles are in good shape, and driving is not particularly hard such as damage occurs to the clutches, I think you will have little to wor about settlement due to migration of fines through the seems especially that you intend to reduce the lateral displacement of the wall (thus reducing bulging and consequently potential opening of the clutch)
2. What kind of fill is it?? Did you have a chance to test and find the percentage of fines in it?? Just a thought.

In generating engineering merits, using grout curtain can
1) Increase the factor of safety against base heaving
2) Reduce the seepage flowing into the excavation
Certainly, the sheet piles are assumed to be well interlocked which highly dependent on the workmanship.
Except the head difference between the front and back of sheet pile wall is very high, seepage and base heave usually is not a concern. However, I would suggest you to review the geological profile to identify any existing boulders and obstructions causing part of sheet pile cannot
penetrate to the design level. There are some case histories where the part of sheet pile obstruted by the boulders and the coarse sand retained behind flowing into the excavation through the holes and finally causing sinkhole formations at the back.
Hope it helps

to use in design of earth dams

Some sealants are applied to the joints in the field while others are delivered with the sealant already in the interlock joints. Quality control is better with shop applied.

I also recommend using hot-rolled sheet piling instead of cold-formed sheet piling. The hot-rolled sheets have a tighter, less pervious interlock. The joint sealant systems need the confinement of the tight interlock to provide an effective seal.
