Lately I have noticed that after a hard rain, I get standing water on
one end of my house at the base of the concrete slab foundation. It
also saturates the yard (grass) for several feet out from the
foundation (the ground is clay).

I have lived here 18 years and this only started this year. What
could cause it? Can it cause any harm to the slab?

Do you or your neighbor have a underground leak that will pre-saturate
the area?

>Can it cause any harm to the slab?

Yes. The brick and foundation can rot because water dissolves soluble
materials like lime and calcium in the block and mortar.

I don't think there is a leak. The ground is dry except when we get a
heavy rain.

The slab is poured concrete. Does that make a difference? Or is
there block and mortor under the slab?

I've noticed that my house is settling too. I've had to haul in dirt
several times over the last 20 years to keep the drainage going where
it should.

Get a shovel and do some landscaping so that water does NOT stand
next to your slab.

what about downspout drains? well away from home?

if they led into a drywell it may well be plugged backing the water
into the line or a downspout line may be leaking near your home/

try running a garden hose down the lines.........

for a hour at least/

if the downspouts dump at the base of home at least run water away with
that flexible corrugated plastic pipe to see if it helps.........

what you have needs serious attention.

if all else fails a underground dug footer drain is in order.
