Are you striving for excellence in your construction projects? In the construction industry, achieving seamless and durable concrete joints is essential.

At Danterr, we understand the critical role of jointing sleeves in ensuring strength and durability to concrete structures; our concrete jointing sleeves feature new technologies to give you the best in industrial production and enable you to deliver results on site. Let’s explore how our Speed Sleeves, Flange Dowel Boxes, and Speed Sleeve Nailing Plates can revolutionise your construction process.

What Are Concrete Jointing Sleeves?

Concrete jointing sleeves are specialised components designed to facilitate the proper alignment of concrete joints. These sleeves facilitate dowel installation which helps control the load bearing on the joints, control movement in the vertical direction, and prevent cracks. By using concrete jointing sleeves, construction can achieve more durable and seamless joints, ultimately enhancing the overall quality and longevity of the structure.

Danterr’s Concrete Jointing Sleeves

Speed Sleeves: Speed Sleeves marks a new approach to how construction professionals handle concrete joints. Designed to work for friction-cut round dowels, Speed Sleeves eliminate the need for drilling formwork and greasing dowels decreasing vertical movement and preventing potential joint damage.


  • Effortless Installation: Quick to apply, especially for industrial ground slabs with multiple joints. Nailable to wooden form boards using optional nailing plates (sold separately) or compatible with existing/epoxied dowels.
  • Enhanced Joint Integrity: Minimizes vertical movement, ensuring structural integrity and safeguarding load transfer while allowing necessary joint movement.
  • Versatile Application: Available in standard sizes of 16mm, 20mm, 24mm, and 33mm to suit various construction needs.

Technical Specifications:

  • Material: Non-corrosive PVC for durability and resistance to environmental factors.
  • Pack Quantities: Sizes range from 16mm to 33mm, with pack quantities of 50 or 100 depending on size and length.

Flange Dowel Boxes: Provide robust and precise alignment for concrete slabs which is very important for big buildings. These boxes ease the installation, reduce labour costs, and enhance the overall quality of your construction work.


  • Superior Alignment: Provides exact dowel placement, ensuring consistent quality.
  • Cost-Effective: Reduces installation time and labour costs.
  • Durable Design: Made to withstand rigorous construction environments.

Technical Specifications:

  • Material: Galvanized steel for high strength and corrosion resistance.
  • Available Sizes: 20mm, 24mm, 30mm, 36mm to accommodate various dowel diameters.

Speed Sleeve Nailing Plates: Designed for fast and accurate installation of dowels in concrete joints, it ensures sleeves are perfectly aligned, providing a secure and efficient jointing solution. They save time, ensure precision, and are built to last for heavy-duty construction projects.


  • Precision Installation: Ensures perfect alignment for dowels, enhancing joint integrity.
  • Time-Saving: Simplifies the installation process, reducing labour time.
  • Durable and Reliable: Built to last in demanding construction environments.

Technical Specifications:

  • Reusable: Can be used multiple times, providing cost savings.
  • Colour-Coded: Based on diameter for easy identification (e.g., 16mm – Green, 20mm – Red, 24mm – Brown, 33mm – Blue).
