PT Slab Cutting



In a typical post tensioned floor it is possible to locate penetrations of up to 1000 by 3000 mm (3 by 9ft) between post tensioned tendons and to require no other modification to the floor.

Penetrations that require cutting of the post tensioned tendons will need to be checked and designed as would any large penetration in any floor using bonded tendons is as follows:
General Considerations



1. Design the modified floor structure in the vicinity of the penetration assuming that any cut post tensioned tendons are dead-ended at the penetration.

2. Install any strengthening required.

3. Locate tendons and inspect grouting.

4. If there is no doubt as to the quality of the grouting, proceed to step5. Otherwise strip off ducting, clean out grout, and epoxy grout the strands over length of 500 mm (20 in) immediately adjacent to the penetration.

5. Install props.

6. Core drill the corners of the penetration to eliminate the need for over cutting, and then cut the perimeter using a diamond saw.
