CXJ Dual-Cell Center Gland Expansion Joints

They give you the edge in waterproofing.

The unique and innovative design of CXJ expansion joints stops water infiltration in concrete construction joints.

Watertight integration

Featuring extruded, thermoplastic dual gland expansion joint seals, the innovation of the CXJ expansion joint’s unique double-flange construction helps create multi-layered, watertight integration within a concrete waterproofing system.

CXJ expansion joints can help prevent water penetration for positive-side below-grade concrete foundational structures, including:

Backfilled walls

Structural slabs

Blind-side shoring wall applications, such as soldier pile and lagging

Working for structures under continuous or intermittent hydrostatic pressure, CXJ expansion joints substantially reduce the possibility for leaks.

How it does it

CXJ expansion joints consist of extruded thermoplastic, dual-gland expansion joint seals with integrated side flanges. The specialized geometric design of the center gland optimizes performance and reduces strain during movement. Even more, the unique double flange element provides for a multi-layered, water barrier. Along with factory-fabricated transition and termination components, these advantages combine to provide:

Watertight connections
High movement capability
Redundant sealing
Integration with waterproofing membrane

The right size for your application

CXJ expansion joints are available in two sizes:

CXJ-200, ideally installed in a 2” (50mm) expansion joint gap and can be installed in a 2”–3” (50mm–75mm) field gap joint +/- 1.25" (31 mm) movement capability.
CXJ-400, ideally installed in a 4” (100mm) expansion joint gap and can be installed in 3” –5” (75mm–125mm) field gap joint +/- 2.5" (62 mm) movement capability.

Termination pieces are also available for both the CXJ-200 and CXJ-400 sizes:

Boot Termination
Welded End Cap
Inside 90 Degree Corner
Outside 90 Degree Corner
Horizontal 90 Degree Corner
