- Concrete Construction
- Concrete Thickness
- Joint Width
- Expansion in the joint(Amount of movements such as contraction, sitting)
- Water pressure height
In places where ground movements are high (especially where there is an earthquake risk), In places where the water pressure is high, where movements such as expansion, contraction, gouging in the joints are high, the ones with high wall thickness of the damper bands to be selected should be used.
It is useful to pay attention to the following formulas when choosing the cross section length of the waterstop tape
| L < t | Must be |
| L > 6a + d | Must be |
| Y > L - d/2 | Must be |
| X > 2a | Must be |
| L</td > | Length of Cross Section (mm) |
| t | Concrete Thickness |
| a</td > | Largest aggregate grain diameter |
| d</td > | Joint Spacing |
| y</td > | Distance from concrete surface (mm) |
| x</td > | Distance to nearest Rebar |
In order to help, the recommended damper band cross-section dimensions and wall thicknesses according to the concrete thicknesses are as in Table-B.
Table-B
| Concrete Thickness (cm) T< /strong> | Tape Cross-section Length (mm) L< /span> | Band Wall Thickness (mm) a1 (min) |
| 20-40 | 150 | 3 |
| 35-50 | 200 | 4 |
| 40-60 | 250 | 4 |
| 50-70 | 300 | 4 |
| 60-80 | 350 | 4 |
| 80-100 | 400 | 4 |
| 100+ | 450 | 4 |
