Hi -- Last week we had drain plumbing under a concrete-slab
living room floor repaired. The repair people topped
the repair trench with 3-4 inches of redi-mix concrete.
Unfortunately, the resulting surface is porous & very
uneven, such that the linoleum tiles cannot be
replaced. The original surface was a fine, smooth type of
concrete which allowed cementing the tiles, over which
we have an expensive carpet pad and carpet. It seems that the repair needs to be redone to enable
the tiles to be replaced to form an organic
seal and vapor barrier for the overlying carpet. The repair people want to come over and "seal" the
uneven, porous concete, then lay the carpet on top.
without the linoleum tiles. Is this reasonable? Thanks for your response. Roger Williams, Space Sciences Lab, UC Berkeley
