laminate install radiator leak

rockall81

Hi,

I have been trying to install laminate flooring on the ground floor.

i came across two blanked radiator pipes instead of checking whether they are dead, i hammered it down. now i see they are leaking.
I have removed the laminate floor cut off the wet underlay, which i can replace.

Dont know how to fix the leak as it is coming from the concrete floor.

I can think of digging, but i should be careful, reluctant call the plumber as its my first diy flooring gone horribly wrong ..so please help.

Thanks for the help in advance.
