- Suitable for vertical and horizontal movements
- Low vibrations under direct car traffic
- Thermal expansion coefficient similar to resin based floors
- Replaceable rubber seal
- Easy to install / Easy to repair
- Short down time - Trafficable after 24 hours
- High chemical resistance
- Non corroding
- High mechanical resistance
- Joint movement horizontal: 50 mm (-20/+30 mm)
- Joint movement vertical: 30 mm (-15/+15 mm)
- Recessed flange along both sides of panel
- Double waterproof system design with integrated Sikadur Combiflex SG System

Joint design
| Maximum gap width1: | 50 mm |
| Positive horizontal joint movement2: | +30 mm |
| Negative horizontal joint movement3: | -20 mm |
| Positive vertical joint movement4: | +15 mm |
| Negative vertical joint movement5: | -15 mm |
- Width of the gap in the concrete below Sika® FloorJoint PDRS during installation.
- Positive horizontal joint movement is the amount the gap can horizontally open, compared to its original width during installation of Sika® FloorJoint PDRS.
- Negative horizontal joint movement is the amount the gap can horizontally close, compared to its original width during installation of Sika® FloorJoint PDRS.
- Positive vertical joint movement is the amount the gap can vertically open, compared to its original gap during installation of Sika® FloorJoint PDRS.
- Negative vertical joint movement is the amount the gap can vertically close, compared to its original gap during installation of Sika® FloorJoint PDRS.
Note: To provide a waterproof joint, first, install Sikadur® Combiflex® SG System below the Sika® FloorJoint PB-30 PDRS.
Application
Waiting time to overcoating
Before grinding and applying Sikafloor®-375 on Sikadur®-30/-31 CF Normal + Sika®-FloorJoint PDRS allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 24 hours | 14 days |
| +20 °C | 12 hours | 10 days |
| +30 °C | 8 hours | 7 days |
Before grinding and applying Sikafloor®-359 N on Sikafloor®-375 allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 24 hours | 48 hours |
| +20 °C | 15 hours | 24 hours |
| +30 °C | 8 hours | 16 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
