I HAVE A FIVE YEAR OLD CONCRETE WALKWAY THAT THE LAST TWO YEARS ONE SLAB HAS BEEN CHIPPING AWAY. THIS WINTER I HAD TO USE CALCIUM/SALT FOR THE BAD ICE STORMS WE HAD.
THIS ONE SLAB HAS TURNED COMPLETELY SOFT,AS IF IT NEVER DRIED. YOU CAN ACTUALLY SHOVEL IT AWAY. I NEED TO KNOW IF I CAN GO OVER IT
WITH A VYNAL PATCH/MORTER, OR DOES IT HAVE TO COME UP. ALSO WAS THINKING OF DOING PAVERS, CAN I GO DIRECTLY OVER THE OTHER SLABS THAT ARE STILL IN GOOD SHAPE, OR DOES THAT HAVE TO COME UP ALSO. DOES ANYONE HAVE ANY IDEAS.
