PART 3 EXECUTION
3.1 EXAMINATION
- A. Examine surfaces to receive waterproofing membrane system. Notify Architect if surfaces are not acceptable. Do not begin surface preparation or application until unacceptable conditions have been corrected.
3.2 SURFACE PREPARATION
- A. Prepare surfaces in accordance with manufacturer's
instructions.
B. Cure concrete a minimum of 72 hours.
C. Ensure concrete is clean, dry, smooth, and free of voids.
D. Remove sharp protrusions and repair surface defects.
3.3 APPLICATION
- A. Apply waterproofing membrane system in accordance
with manufacturer's instructions.
B. Ensure accessory materials are compatible with membrane and approved by membrane manufacturer.
C. Prime surfaces to be covered in 1 day with applicable primer. Reprime uncovered surfaces next day.
D. Inspect membrane before covering and repair as necessary. Cover tears and inadequate overlaps with membrane. Seal edges of patches with pointing mastic.
E. Perform flood testing of horizontal applications, as required. Mark leaks and repair when membrane dries.
F. Avoid use of products which contain tars, solvents, pitches, polysulfide polymers, or PVC materials that may come into contact with waterproofing membrane system.
3.4 PROTECTION
- A. Protect membrane on vertical and horizontal
applications with immediate application of waterproofing protection
course, if no drainage system is used, or rolled matrix drainage system.
Use pointing mastic as an adhesive.
B. Backfill immediately using care to avoid damaging waterproofing membrane system.
