I'm replacing my liner and I see mud around the edges where the wall meets the floor and it looks like ground water may be seeping in.
Is this dirt coming through from behind the wall or the floor dissolving where the water is seeping in. Probably a bit of both.

Any thoughts?

The floor is pretty hard but it is not concrete. I can press my fingernail into it and make a mark. Closer to the edge it seems a bit eroded.
Does this need to be repaired? Is there a problem with water seeping in like it is doing?

Thanks for the replies.

The floor is vermiculite, not concrete.

I think a bit of ground water seeping on the edges is not a problem. The pressure of the water in the pool keeps it away.

@jimmythegreek thoughts?
 
Smooth out the floor with some vermiculite or mix of vermiculite and dry cement or just some dry cement.

clean it up the best you can and use straight portland cement for any divots or pimples. if its a big spot then you need a patch of vermiculite. thats just muddy groundwater coming thru. dont leave the pool long like this, if you havent ordered the liner yet brace the pool if the water keeps coming, rain can do damage to an empty steel wall pool. yours looks pretty solid with no real rust
 
Thanks for the reply, the walls are actually a composite material, not steel. Does that make a difference? The seepage doesn't seem to be too bad. I still have my old liner that i moved out of the way so i could measure the pool properly. Should i spread it out in case of rain? I'm afraid it might rain this weekend before my liner comes.
 
Type of walls does not make a difference to how you treat the floor.
 
A little rain is ok as long as you have dry ground and pitched away from pool. You dont need to remove liner to measure theres fudge factor they stretch. The hopper angle and flat to transition is the most important #. Basically a liner pool uses the composite or steel wall to seperate earth from water. It's a retaining wall. Water is what holds up the wall to push against it. With no water it's just thin plastic holding back earth. If water is leeching alot and steady brace it if its gonna rain alot. Sprinkles amd light rain will be OK
 
Thanks so much for your input. Regarding the hopper angle and flat to transition measurements, those are the two that I have the most concern about. The shallow break and where it meets the hopper are not very defined. If there is an error in measurement, is it better to err on the shorter or longer side and is being within an inch an acceptable variance?
