"These sleeves minimize joint movement, prevent cracking, and ensure the floor's integrity under heavy loads."

Diamond dowel sleeves and speed dowel sleeves are crucial components in Armour Joint systems because they enhance the stability and longevity of concrete floors by ensuring proper alignment, load distribution, and protection of dowel bars. These sleeves minimize joint movement, prevent cracking, and ensure the floor's integrity under heavy loads.

Here's a more detailed explanation

Alignment and Load Distribution

Diamond dowel sleeves and plates, particularly the diamond shape, help to ensure that adjacent concrete slabs remain aligned, even under pressure, and distribute loads more evenly across the floor surface.

Protection and Durability

The sleeves protect the dowel bars from damage during construction and subsequent maintenance, enhancing the overall durability of the connection.

Minimizing Cracking and Joint Movement

By maintaining alignment and distributing loads, these sleeves help to minimize the potential for cracking and joint failures, especially in industrial settings where heavy machinery is in use.

Controlled Movement

Speed sleeves allow for some controlled movement at the joint, reducing stress on the concrete slabs while preventing excessive vertical movement, which can cause damage.

Ease of Installation

Diamond dowel sleeves are designed for quick and easy installation, eliminating the need for drilling holes in formwork, as they are attached to the formwork on one side before the concrete is poured.

Joint Integrity

Over time, movement in the flooring materials due to temperature changes, moisture, or heavy loads can cause joints to shift or loosen. Diamond dowel sleeves and plates help maintain joint integrity by preventing these shifts.
