Huge hole in foundation
MY neighbor has discovered a huge hole in the foundation underneath her Jacuzzi. The soil has eroded and there is a large cavity under the foundation that fills with water whenever it rains. She was told that it is normal for the builder to leave such a hole in the foundation under the Jacuzzi. I find that hard to believe. The hole is irregular and about 1 ft x 2 ft in size. The holes leaves the soil under the house exposed to the inside of the house under the Jacuzzi. It seems to me that such a hole would allow water to intrude, migrate, erode and allow mold to form under the Jacuzzi. Can it be true that a hole like this is normal.
There is no sump pump. What I have called a Jacuzzi may not be. It's a large bathtub that has ports for shooting water under pressure into the tub for massage? The tub sits above the foor in the bathroom. There is a frame built up around the tub and finished with tile. The hole is under the tub "through" the foundation into the soil underneath the house. Since the soil under the slab is below the level of the soil surrounding the house, there is created a pressure differential from outside to inside the house whenever it rains and the soil outside the house becomes saturated wih water. Hydraulically, as long as that hole is there and it is "below" the level of the surrounding soil there will be water flow into the house. Cannot be any other way. Water only flows "downhill." My neighbor broke out two 4 x 6 tiles to see underneath the tub and the water can now flow out from under the tub into the bathroom through the two holes from the removal of the tiles. Not sure if the framing was completely sealing the water from leaking prior to his removing the two tiles. The pump I speak of is one that he rented and stuck into the hole under the foundation and periodically runs (when it is raining) to suck out the water and dump it into the tub for removal. I have a drawing that I made to help understand. I believe that this must have been leaking for years. As long as that hole has been there water has to have been getting underneath his tub and he's just been lucky that it hasn't flooded his house. I appreciate any help anyone can provide.:eek:
First I will say, there absolutely should not have been a hole left under the tub, that is just plain wrong.
But as far as water running up through the hole, unlikely, not unless the land surrounding the house it higher, but if you have water coming up through there, I would think the whole house would be in a giant puddle.
I would be more worried about, insects and rodents.
Are the soils Outside the house pitched Away from the house,..??
Are you saying the surrounding water level is Above the top of the slab/ floor level,..??
The house/ slab should be Above it's surrounding terrain...
How much access to this Hole,..?? Just the 2 missing tiles,..??
How Big/ deep are We talkin',..??
