Shotblast and repair. Heavy duty: spray Polyurea 2–3 mm; medium duty: 2K PU; or SBS under protected build‑ups. Treat movement joints with bands/profiles. Flood test in compartments.
LQ-PODIUM
Summary
Podium decks face dynamic loads, thermal cycling, ponding, and planter moisture. Failures usually appear at hardscape joints, planter interfaces, and penetrations.
Symptoms
- Dampness in rooms below or seepage at podium soffit
- Wet joints between pavers or at movement joints
- Planter leakage staining adjacent finishes
Probable causes
- Rigid/low‑movement membranes under traffic
- Unsealed/insufficient movement joint treatment
- Planter detailing missing root barrier/waterproof band
Solution paths
- Positive‑side heavy‑duty membrane system
- Dedicated joint systems (pre‑formed bands/profiles)
- Planter root‑resistant detailing with continuous membrane
Recommended technologies
- Polyurea (2–3 mm) for heavy duty decks
- 2K PU spray/hand for medium duty
- SBS membranes under protected build-ups
Quick SOP
1) Shotblast/grind; repair defects; verify slopes to drains.
2) Prime; apply selected membrane to spec DFT (polyurea fast‑cure ideal).
3) Treat movement joints with flexible bands/profiles.
4) For planters: root barrier + membrane upstands; protection layer; drainage board.
5) Flood test compartments; reinstate finishes/pavers on pedestals.
QA / acceptance
- Pull-off ≥1.5 MPa (spray PU/polyurea); joint bands continuity
