Resilient rubber is a flexible material that is capable of recovering its original shape or form after being subjected to various stresses. Resilience measures the elasticity of a rubber compound, and this property makes it useful for manufacturing connectors that can make pipeline joints watertight.
Trenchless video inspection can help detect leaking or offset joints and help remedy them by installing resilient rubber using trenchless rehabilitation techniques.
Trenchlesspedia Explains Resilient-Rubber
One type of resilient rubber is made from ethylene propylene diene monomer (EPDM). EPDM rubber seals can be installed in joints of manholes and also as pipe gaskets.
Resilient rubbers provide a positive seal to minimize leaks between manhole walls and connector and between connectors and pipes. Plastic pipes such as high-density polyethylene (HDPE), polyvinyl chloride (PVC) and polyethylene (PE) pipes are widely used for their flexibility and ease of installation. However, where these pipes connect to concrete structure connections, there is a chance of causing joint breaks and leaks. This is because plastic pipes can bend to accommodate a typical soil load but concrete cannot. Where such unmatched joints exist, there is a high chance of a leaking connection.
Resilient rubber connectors are excellent in such conditions because of their ability to allow some degree of pipe movement without causing leakage.
