If you have water in the basement after the rain has stopped then it may cause floor cracks.
Water coming into basement through floor.
This situation will cause the water table to rise sometimes to the point that water comes up through the basement floor and the basement floods.
Pressure from the water beneath your home can cause cracks in the basement floor which leads to water coming up through the basement.
There are a few reasons for this.
Resolve the issue of any standing water outside the edges of your basement walls.
This pressure is due to poor drainage and dirt soil.
For example when there would be a standing water under your floor your floor may get the cracks.
If not caught very quickly there will be no chance of repairing the hardwood floor.
Rising groundwater causes hydrostatic pressure and that causes soil to push on your basement walls and floor.
Another reason water seeping through the floors is such a serious issue is if you have a two story home or live in a multi level apartment complex.
There are various ways through which you can prevent water coming in your basement at a point where walls meet floor.
But before you diagnose this as your problem be sure that you first check for the following.
Just look at these simple ones.
If water is coming through the basement floor or coming in where the basement walls meet the floor then the source of the water is likely subsurface groundwater.
Water seeps its way through the soil surrounding your house and pushes up against your basement floor and walls where the hydrostatic pressure is rather great.
If the standing water comes from the floor then you know the water cut through the entire piece of wood.
The most probable explanation for why water is coming up from your basement floor is groundwater.
Water coming up from the basement floor can lead to big headaches.
A flooded basement can cause interior damage and even destroy irreplaceable mementos like your family photo albums or heirlooms that you may have been keeping in storage down there.
If it is cracked the water would start coming up through it and further damage the nearby area.
Check for leaking pipes or appliances in your basement.
Carefully check and repair any leaking pipe near the boundary where walls and floor met.
If you have water seeping through your basement floor you may have a high water table and the hydrostatic pressure is pushing up under your basement floor and forcing water into your basement.
