The 22' l, x 4'w x4' deep concrete bunker is between the subfloor and the slab foundation?

Question

We don't have basements in Texas and I don't want or need to use the 'bunker'. I need to seal it up once I pump the water out and the foundation is evaluated and repaired.

Answer 1

I read your other question, and not sure bunker is the best word for it, sounds like a horse trough or a cistern, it may have preexisted the house and the contractor was to lazy to remove it before construction (you'd be amazed at the amount of construction garbage and spiders you find while restoring homes), or it was put there to trap rain water (little unusual for the area but not uncommon on islands) it would have piping to it for that though.

Id say the cheapest and easiest thing to do would be to rent an electric roto-hammer and punch a few holes in the bottom and corners so it drains in the future and just leave it, maybe fill it with gravel. If waters getting into the foundation it probably needs to be sealed and drain tile installed and that would keep any more water from collecting unless the water is piped in from the gutters or leaking from the house. Cant really say much without seeing it.

Answer 2

If its full of water, you may have to consider installing a sump pump down there. You may need this space to access utilities, ductwork or to add same later.

From what you describe, I can't imagine this costing you anything to keep it, as opposed to filling it in. Deal with the water incursion and leave it there would be my recommendation.

Answer 3

make one heck of a septic tank !
that's a fine explanation . what do you want to know !
Sorry i can only answer once . you'll have to ask again .
i asume it is lower ground and cost efective way to drain and fill too level .
i cannot picture this but stopping the water would be my main objective !

Answer 4

the best thing to do there is have it f illed with concrete then you wont have any more problems in the near future
