Rubber waterstop, made of quality SBR (styrene butadiene rubber), neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally, designed to be cast in the concrete, rubber waterstops are ideal for applications where high physical properties of rubber are required. For example, reservoirs, dams and other water retaining or excluding applications with high movements or water pressure.
Feature:
Installation:
In general, the right way of waterstop installation determines the performance in preventing waters and other waterborne chemicals. Any deflection and misalignment should be avoided - that means the best way of installation is to fix the PVC waterstop to the surrounding steel. So for easy installation, three economical methods are provided by our company as shown in the picture:
| Physical properties | Test methods | SBR | High tensile neoprene rubber | Natural rubber |
| Water absorption 2 days at 70°C (% change) | ASTM D-471 | 5% (max) | 5% (max) | 5% (max) |
| Hardness shore A | ASTM D-2240 | 65 | 65 | 65 |
| Tensile strength | ASTM D- 412 | 3000 psi (min) | 2500 psi (min) | 3500 psi (min) |
| Tensile strength at 300% Modulus | ASTM D-412 | 1150 psi (min) | 1150 psi (min) | 1450 psi (min) |
| Ultimate elongation | ASTM D-412 | 450% (min) | 450% (min) | 500% (min) |
| Compression set 22 hours at 70°C (% original deflection) | ASTM D-395 | 30% (max) | 40% (max) | 30% (max) |
| Accelerated aging 96 hours at 70°C (% of tensile strength before aging) | ASTM D-573 | 80% (min) | 80% (min) | 80% (min) |
| Accelerated aging 96 hours at 70°C (% of elongation before aging) | ASTM D-573 | 80% (min) | 80% (min) | 80% (min) |
| Ozone resistance 7 days at 50 PPHM at 70°C, 20% elongation | ASTM D-1149 | No crack | No crack | No crack |
