Filling an old inspection pit in a garage

Postby OldDodge » Sun May 09, 2021 7:08 am

I've demolished our old garage which has an inspection pit.
The bottom is below the water line and in wet weather a pool of water forms.
I want to fill it with the blocks from the garage and then pour cement to the top six inches so it's level with the floor.

I have three questions:
1) Do I need to drill holes through the base of the inspection pit to prevent water pooling or can I just fill and forget?
2) What's the consequences of filling without drainage?
3) Can I lay the blocks down whole filling the gaps in with rabble or is it best to compact the blocks to reduce the gaps?

Thanks in advance

Hi olddodge
If water collected in the pit and it was not due to surface water run off, then just as it fills with water it will empty through the same faults.
Fill the pit packing blocks as tightly as possible and cap off as you propose. The water table will be at the same height under the floor and in the filled in pit.
