Q
Are there any problems associated with casting SFRC against a water proof membrane?
A
No failures of the plastic liner due to fiber punctures have ever been identified. the abrasion from sharp aggregates during placement of the concrete poses just as big of a threat to the liner as do the steel fibers. After placement the fibers tend to move around and re-orient themselves during vibration which relieves any pressure of an individual fiber on the liner created during placement. Many projects using SFrc are constructed with cast-in-place and sprayed shotcrete directly in contact with water proof membranes.
