Civil
Engineered for the structure.
Load cycles measured in decades, not seasons.
Bridges flex, ground shifts and joints move every day for the life of the structure. The rubber specified into civil infrastructure has to absorb that movement and survive weather, ozone and UV across a 30-year service window. RDL develops and produces bearings, seals and expansion components engineered to the movement range and load of the structure, certified to standard before they are built in.
Bridge expansion joints
Sealing systems that take up thermal and traffic-induced movement without leaking the deck below.
Structural bearing pads
Load-distributing elastomeric pads specified to bearing pressure and rotation.
Waterstops and joint seals
Cast-in profiles that keep water out of movement joints in concrete structures.
Anti-vibration mounts
Isolators that damp machinery and traffic vibration before it reaches the structure.
Drainage and culvert seals
Gaskets engineered for buried service and long-term ground contact.
Compounds for this environment.
- NRNatural Rubber
High resilience and fatigue life. The basis for laminated structural bearing pads.
- CRNeoprene
Weather, ozone and ageing resistance for exposed seals and joints.
- EPDMEthylene Propylene
Ozone and UV stability for exposed seals and waterstops.
Send us the joint that has to move for thirty years without leaking.
The structure, the movement range, the load. We specify the compound, prototype the part and prove it on the bench before it ships.
