BONDEK® INSTALLATION AND CONSTRUCTION Step 1: Open BONDEK® sheet bundles. Step 2: Place props if required. Step 3: Trim BONDEK® sheets if required and place. Step 4: Fix BONDEK® sheets to steel beams if required. Step 5: Fix steel Edgeform. BONDEK® USER GUIDE Step 7a) PT Hold Down Clip. Step 7: Place reinforcement and post tensioning if required.

Step 8: Place concrete. Step 9: Allow slab to cure and remove props. Step 10: Install services and ceilings with BONDEK® accessories. GENERAL ENGINEERING NOTES • Ratio of two adjacent slab spans are equal • he ratio of the longer slab span to the shorter slab T span does not exceed 1.2, that is longer span/shorter span ≤ 1.2 2. The tables shall be used for normal density concrete (2400kg/m3). 3. The lines of support shall extend across the full width of the sheeting and have a minimum bearing 50mm at the ends of the sheets and 100mm at intermediate supports over which sheeting is continuous,...
