The CXJ Series:

CXJ-200 and CXJ-400

Dual-Cell Center Gland Expansion Joint

200x147_CXJ-400

The CXJ-200/CXJ-400 expansion joint system consists of an extruded, thermoplastic, dual gland expansion joint seals with integrated side flanges that are used to waterproof structural concrete expansion joints for positive-side below grade foundation walls and under structural slabs. The CXJ-200/CXJ-400 expansion joint system can be integrated with CETCO’s waterproofing systems to create a true single source waterproofing system.


Movement at the joint is accommodated by the geometric shape of the double-cell, center gland configuration with two material layers to form the system. The center gland geometric shape is purpose-designed for low strain during movement, for optimal performance.

 

The unique double flange design of the CXJ-200/CXJ-400 facilitates multi-layered, watertight
integration with the waterproofing system. A termination bar and anchors are installed on both sides of the center gland to mechanically secure both inside flanges of the CXJ-200/CXJ-400 to the concrete.

Applications

Structural concrete expansion joints in below-grade foundations, including:

  • Backfilled walls
  • Under slabs
  • Blind-side shoring wall applications, such as soldier pile and lagging

Can be used for both hydrostatic and non-hydrostatic conditions

 

Features

  • High movement capability
  • Dual-cell center gland provides redundant sealing
  • Integrated dual side flanges provide integration with waterproofing membrane
  • Factory-fabricated transition and termination components
  • Heat welded seams for watertight connections
