FIGURE 8.13
A one-block wide tunnel and ladders keep the water at bay. I've removed
all the stray water sources in the lower half of the tunnel by swamping them with sand
blocks dug out earlier.
2.
As you fill in the interior, also start building up the external shell on the outer side
of the tunnel. Use your final construction materials such as glass blocks because
this will form the permanent structure. Keep some soft blocks at the ready to plug
up any water breakthroughs. The wall only needs to be two blocks high. Given that
you're on the bottom of the sea, you can always dig down later to create more
height. Place some torches as you go to create additional light, although they won't
attach to glass.
Note:
Flooded In? Head to the Source
It's quite usual to find your tunnels still half flooded even after all the
walls are done and every ladder is in place. The damp ankles are caused
by water source blocks that still exist on the floor of your perimeter tun-
nel. To remove them, place any kind of soft block wherever you can see
anything that looks like the head of the water spring. This kills the water
source,andyoucanthenquicklyshoveloutthesoftblock.Rinse andre-
peat until all the source blocks have been extinguished and your tunnel
has dried.
