Question...
"Is it common practice to sleeve the penetration when penetrating a slab on grade ?"
RepWars Reply...
No, it is not common practice. However, some piping may need protective coating to isolate it from direct contact with the concrete to prevent corrosion, such as copper piping. Stub-ups for floor outlet toilets also require isolation from the slab to allow future installation of the closet flange.
Question...
"What is the difference between slab on grade and slab on earth fill ?"
RepWars Reply...
A slab on earth fill is a slab on grade that has additional earth/sand fill provided prior to pouring concrete in order to provide the proper elevation, leveling and compaction required.
Question...
"Are watertight seals provided at the penetrations ?
"
RepWars Reply...
No.
