Summary and Description:
This product is an extruded elastomeric configuration that will seal the expansion or contraction joint opening from the intrusion of water and debris. The cross-section has an arrangement of internal webs designed to exert a continuous and uniform horizontal force against the joint walls. It is designed to exist in constant compression throughout the range of joint movement.
The BR-Series shapes are engineered with a heavy-duty web structure exerting maximum force for heavy traffic and high load application. The configuration features a one to one width/depth ratio, with a progression of internal diamond-shaped web constructions. Movement is absorbed in a single center groove dividing two virtually horizontal top webs, which collapse upward upon closure.
This design is especially suitable for bridge and large structure applications. To handle the impact of vehicular and particularly truck traffic the seal is installed between steel armored edge angles.
