Piling through geotex liner
Piling through geotex liner
(OP)
Hi,
I'm a mechanical engineer wanting to get some insight into what to when a geotext liner in a bermed area get pierced by a pile. I'm asking this question in hope to get some basic knowledge so when I ask our Contractor to recommend a solution, I will have some fore knowledge to know if they are leading me down the garden path or not.
The oil well site is bermed and has a layer of geotext fabric to line the berm as containment in case of spill. We are adding new skidded equipment to the well pad and we need piles in order to support the equipment. The pile, obviously, will pierce the fabric. Is this a concern or does one have to dig down to the fabric and seal the penetration? If so, how's that done? I'm not looking for details but just a quick explanation is sufficient. Thank you.

RE: Piling through geotex liner
you could look into placing a shallow foundation above the geosynthetic layer so as to maintain the integrity of the liner. You may have issues with tearing of the liner under the foundation loads if you aren't careful engineering this option.
Or you could dig down and install sleeves w/boots through the liner for the piles to pass through. Make sure you get the pile locations right, though.
Just my initial thoughts, and I don't have much idea as to the costs.

After the pile is installed, you can have a liner professional install a sleeve up and around the pile. The sleeve should be sealed wiht a thermoplastiv or chemcical weld to the existing liner where the liners meet at the bottom.
