Translation needed please

Can someone translate this phrase for me? i received it as an email, might be part of a joke :D

Tanto ha dado la gota en el cemento, que se ha abierto un hoyo

Thanks

So much the droplet hits the cement that a hole has been opened.

I think that it's a metaphor about a small thing/fact (like a droplet) that is repeated many times and finally causes damage to a solid/strong thing (like cement).

Thanks alot :)

The above phrase means:
Both have been given the drop in cement, which has opened a hole.
Not sure in which context this sentence has been used.

Hi Beth,
I am not sure that you can use "Both" in that phrase, Tanto means "Both" but in other context, in this context Tanto means "So much".
