DILEX-BWS - Pavement expansion joints


Expansion joint profile for ceramic flooring with hard plastic side elements. The upper movement zone is 5 mm soft CPE.

Height (mm)
Long (cm)
Tax excluded


Pre-fabricated movement profile for tiled coverings. The perforated anchoring legs, made of recycled rigid PVC, are secured in the tile adhesive beneath the tiles where they transmit occurring movements to the soft CPE movement zone (the upper movement zone is also the visible surface).

The movement zone absorbs compressive, tensile, and shear stresses and is only 5 mm wide, matching common grout joint widths. Consequently, the smaller width absorbs relatively limited movements; this should be taken into account when evaluating the requirements for a specific application. Schlüter DILEX-BWS is particularly suited as a movement joint for tile coverings installed over Schlüter DITRA 25 .

If larger movements within the covering are anticipated, installation of Schlüter DILEX-BWB, with a 10 mm movement zone, is recommended.

Schlüter DILEX-BWS is suitable for both residential use and medium-duty commercial applications such as offices or stores. The profile is also suited for exterior use.

Expansion joints for ceramic floors DILEX-BWS


Schlüter DILEX-BWS consists of lateral perforated anchoring legs and side sections made of recycled rigid PVC, connected by a bottom and top movement zone made of soft CPE.

Material properties and areas of application:
The material is resistant to most chemicals commonly encountered in tiled environments and is formulated to inhibit fungi and bacteria growth.

In special cases, the suitability of a proposed type of material must be verified based on anticipated chemical, mechanical, and/or other stresses. The profile’s CPE movement zones are UV-stable and free of softening agents.

Schlüter DILEX-BWS is a surface movement profile for tile coverings set in the thin bed method. The profile must align directly over the existing movement joint in the substrate. It is not suited for use above structural expansion joints.


  1. Select Schlüter DILEX-BWS according to tile thickness.
  2. Apply tile adhesive to the area where the profile is to be installed, using an appropriate notched trowel.
  3. Press the trapezoid-perforated anchoring leg of Schlüter DILEX-BWS firmly into the adhesive and align it. Continue any movement joints from the substrate in the same dimensions.
  4. Trowel additional tile adhesive over the trapezoid-perforated anchoring leg to ensure full coverage and solid bedding.
  5. Firmly press the adjoining tiles into place and align the upper profile edge flush with the tile (profile should not protrude over the surface of the covering; preferably, it should be approx. 1 mm lower). The tiles must be fully embedded in the area of the profile.
  6. Leave a joint of approx. 2 mm to the profile.
  7. Completely fill the space between the tiles and the profile with grout. Since cement-based grouting materials cannot establish a lasting bond with synthetic materials, tearing at the profile joint cannot be ruled out.


Schlüter DILEX-BWS is resistant to fungi and bacteria and requires no special maintenance. Clean the profile along with the tiled surface using common household cleaning agents.
