J & JP Series Sealing Systems Support The Most Critical Infrastructure

Above: J & JP Series Sealing System installation. The J & JP Series Sealing Systems include an extruded elastomeric profile and a high-strength, two-part epoxy-based structural adhesive.


As a designer, supplier and manufacturer of engineered rubber, steel and concrete products for the transportation and infrastructure sector, D.S. Brown is a critical partner in key bridge, pavement and architectural projects worldwide.

The J & JP Series Sealing Systems, one of D.S. Brown’s key proprietary product lines, includes an extruded elastomeric profile and a high-strength, two-part epoxy-based structural adhesive. The J & JP Series Sealing System, when inserted into an expansion joint in a substrate, will seal the opening from the intrusion of water and debris. This unique design allows the seal to function under compression as well as in tension.


  • J-Series Sealing System: (top right) The standard J-Series can be used for both bridge and highway as well as parking garage applications, where normal as well as vertical movements are a design parameter.
  • JP Series Sealing System: (bottom right) The JP-Series is designed for architectural applications that are required to meet ADA guidelines, providing a smooth pedestrian-friendly walking surface.

D.S. Brown’s team members manufacture and develop sealing and repair products for bridge, highway and airport markets at its facility in North Baltimore, Ohio.

J-Series Sealing Systems, modular joints, high-load bearings and other products were provided for an ambitious project to widen the New Jersey Turnpike, one of the most frequently traveled highways in the United States. The turnpike – which winds through New Jersey, Pennsylvania, Delaware and New York State – was expanded to 12 lanes in some places.

Features and Benefits of J & JP Sealing Systems
  • Ease of Installation – J & JP Seals have specially designed internal webbing to facilitate installation and do not require the use of a vacuum to collapse or inflate the seal for purpose of installation.
  • Concrete and Steel Adhesive is VOC Compliant – The adhesive has a zero VOC rating. The material resists humidity, salt spray and extreme temperature ranges.
  • Fatigue Tested for One Million Cycles – The profiles were cyclically opened and closed in tension and compression for one million cycles. The seals were stretched to 200% of their original width with no bond failure.
  • No Blockout Recess Required – The J & JP-Series are a solid choice with the precast concrete industry in that no blockout recess is required. The seal profile can be installed directly between the joint interfaces.
