All fortresses has to deal with dampstone on a low z level.
Seems to be impossible to find a free dampstone spot.

The staircase is filling with water... 

[endlessblaze]

Your in an aquifer zone.
If it’s a light one you should be able to dig down to dry stone fairly easily.

If it’s heavy, your going to have a harder time breaking through unless you can go around it

[Shonai_Dweller]

Build a wall around your staircase. That'll block the water. With a light aquifer you've plenty of time to get it done.

With a heavy aquifer (or if you're playing 44.12) then, yeah, you need the wiki and are kind of screwed.

A wall : .. just after digging the stair to de level below it is filling up with water slowly ..its now complety filled with water this level
No way for building a wall
Is it at water level 1 - 2 that building of a wall is maybe possible..?
The current stair is become useless , or i must pumped out water from level below   

With the new replacement stairs , i must keeping going digging thrue the layer then..

No, heavy aquifer handling is for now not realistic to do

Water levels were made more forgiving in 47.x. At 1 you can still build a wall. Maybe 2 too? Not sure. Dig a new set of stairs. You'll get the hang of it eventually. 

Most people avoid heavy aquifer embarks unless they're specifically after the challenge. Just not much fun to deal with.

With waterlevel 2 there seems to be no wall building possible.
Once i mined out the core tile under the floor reaching a z level below , the water is starting to seep thrue the rock ( i think)
A extra wall around the stairs must mined out and then a wooden wall placed ( no stone present ), but the water is too fast
Once it is water level 2 on the intended build wall tile, there is no wall build possible

Keep on digging in dampstone must be the answer for going deeper ?

I build stairs, surround it in a wall, then build the next level down. Once your wall is up, no more water will seep through. If it's going too fast, you're probably on a heavy aquifer. Give up or study the wiki for how to get through that. A few z-levels down the damp stone will end.

Thanks
A heavy aquifer i thought i did not embark there
Once a stairway is made on a level reaching the bottomtile , i must then fast mine out the outer walls
I must try this out

With light aquifers, you have plenty of time. You can dig stairs down to stone, mine out an area, build a workshop and make stone blocks to make a nice wall before it becomes a real issue. If it's overwhelming, it may be a heavy aquifer or you've got too much other stuff going on. Generally, it's good practice to get through the aquifer first before working on much else.

Condcern is  how to get stone blocks ..in the last fortress there were no stones to find, or do i miss something?
I  did not get stone blocks from the mine out damp stone..or ?
By the way i made a wooden wall, but is it water persistent ?..if it stays waterlevel 1 or 2 it no issue.
Can be that a to made stonewall is waterproof for starting to build?

Well i lost my fortress again, because not be able for a  z -level rooms  connect with a stair (dampstone issue) with  a mainhall
way.

Avoid heavy aquifers. They're a pain to dig through without pumps or clever tricks involving freezing temperature.

Light aquifers are fantastic sources of water that aren't too difficult to dig straight through.

When digging down, designate a 2x2 or 3x3 up/down stair going down like 10 Z levels or so. From the surface all the way down 10 levels (or however deep you want your fortress). This is deep enough to get through all soil layers and to stone, where all proper dwarven forts should be constructed. At the bottom of this up/down stair mine out a room. A 10x10 room is big enough.

Water from the light aquifer will fall down the up/down stairway into this empty room. The water will spread out on the ground and will passively evaporate away without building up. As an added bonus, this creates mud which can immediately be used for underground farming.

You can dig out the rest of your fortress from here. Extend that 10x10 room out with tunnels leading off of it, other rooms, storage, workshops, bedrooms, etc.

Then on the surface build a bridge over the down stairs tiles at the surface. You can't block them all off. You will need temporary access around the bridge. Build a lever somewhere safe in your fort, underground. Link this lever to the bridge and pull the lever to retract the bridge. Now build constructed floors on the down stairs tiles that are not covered by the retracted bridge.

This secures your entire fort with a bridge. Pull the lever and the only access to the surface is cut off in a way that cannot be destroyed by building destroyers.

Just make sure to retreat everyone inside before doing this! Make a burrows for the underground area and restrict civilians to this burrow. Then once everyone is inside pull the lever. Seal off the surface.

There is so much noise in this thread about issues that don't exist.  If was a heavy aquifer then no wall would get made, so pointless to even discuss it.

Since it is a light aquifer it is easy to pierce and contain.

If you are using stairs to get down. 

1. Keep making stairs down until you get to an area which doesn't contain water bearing rocks, than go at least 1 more deep.
2. Dig a short tunnel off the bottom of the staircase - 10 tiles long should be enough.  If the end of the tunnel begins to get water in it, extend it.
3. Build a masons workshop - Produce rock blocks.
4. Mine out soils around the staircase.  If it is water bearing rock, smooth the rock.
5. Build walls around the staircase. 

If you are using a ramp - because you want the traders to go into your underground fort.

1. Keep making ramps down until you get to non-water bearing rocks, than go 1 deeper.
2. Dig a short tunnel off the bottom of the ramp - 10 tiles long should be enough.    If the end of the tunnel begins to get water in it, extend it.
3. Build a masons workshop - Produce rock blocks.
4. Mine out soils around the ramp - except for 1 tile, removing all the tiles under the ramp will stop travel between levels.  If it is water bearing rock, smooth the rock.
5. Build walls around the staircase. 
6. Dig out the remaining tile and replace with a wall.

The ramp method can produce more water over multiple level aquifers since you are exposing more aquifer.

Wooden walls work perfectly. Generally that's all you're going to have access to.

I will look at your workflow, but rocks  are not available in the last fortresses i had so far.     
Depends on the embark start position  ?, don't know yet if i can  choose a rocky subterranean layer at  once
Sand or clay are more likely as surface for embark ?

Cut trees.
'd' dig stairs.
Surround stairs on aquifer level in wooden wall.
Dig next layer of stairs. Etc.

Doesn't need rocks.
