Concrete slab repair

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Any suggestions for adding three to four inches of concrete on an existing
slab? The slab has been previously abraded in unsuccessful attempts to
install a topping and there needs to be a new radiant heat system installed
in the new concrete ( a grid of 1 inch pipes, typically attached to any
reinforcement), necessitating a layer of insulation between old and new.
Particular concerns will be crack control and curling.

The reason for the contractor abandoning the topping repair was the poor
quality of the substrate, revealed during scarifying. Replacement of the
slab is not an option.

Thanks in advance.
