Expansion Joint Systems Supplier in the UAE
Globix Trading supplies preformed expansion joint covers, PVC and rubber waterstops, joint filler boards and movement joint sealants across the UAE.
Movement joints have to accommodate thermal expansion without leaking or failing under traffic. The system depends on the joint width, the movement range and whether the joint is trafficked, watertight, or both.
We supply aluminium and rubber joint covers for floors and walls, waterstops for construction and movement joints in water-retaining structures, and the filler and sealant to complete the detail.
What We Supply
Technical data sheets available on request for every product.
Expansion Joint Covers
Aluminium and rubber profile systems for floors, walls and ceilings in standard widths.
PVC & Rubber Waterstops
Centre-bulb, ribbed and dumbbell profiles for construction and movement joints.
Joint Filler Boards
Bitumen-impregnated fibreboard and closed-cell foam fillers.
Joint Sealants
Polyurethane and polysulphide sealants rated for the joint movement class.
Choosing Expansion Joint Products
Movement joints let slabs, walls and facades expand and contract with UAE temperature swings without cracking. Each component has a specific job.
| Component | Typical use | Points to check |
|---|---|---|
| Joint filler board | Slabs, screeds and flooring perimeters | Compressible board forms the joint; seal the top with a suitable sealant. |
| Backer rod and sealant | Facade, floor and wall joints | Backer rod controls sealant depth and prevents three-sided adhesion. |
| Preformed compression seals and cover plates | Large movement in decks, car parks and floors | Choose by total expected movement and traffic loading. |
| PVC and rubber waterstops | Below-ground and water-retaining structures | Must be fixed accurately before the pour and kept continuous across joints. |
Send the joint width, expected movement, location (floor, wall, roof or below ground) and length in metres. We will quote filler, backer rod, sealant and any covers or waterstops together. Request a quote or message us on WhatsApp.
How to Specify and Order Expansion Joints
What to settle before you ask for a quote, so the joint is sized for the movement and the load.
Get the movement figure first. Everything depends on how far the joint must move. Ask the structural consultant for the design movement in millimetres, or work it from the joint spacing and the temperature range the element sees. A joint sized from its width alone is often under-specified.
Do not confuse joint types. An expansion joint takes movement and runs through the full structure. A control joint only directs shrinkage cracking in a slab. One product does not do both jobs.
Choose by location and load. Walls and facades usually take backer rod and a flexible sealant. Floors with foot traffic take filler board with a sealant or a cover plate. Car parks and decks carrying vehicles need preformed seals or heavy-duty covers rated for the load. Below-ground and water-retaining structures need waterstops fixed before the pour.
Check the extras. Say whether the joint must be watertight, fire-rated or match a floor or wall finish. A fire-rated joint needs a tested system, not just a sealant.
Details that cause failures. Backer rod stops the sealant bonding on three sides. Joint faces must be clean and primed where the data sheet requires it. Sealant is commonly installed at about twice as wide as it is deep, and where possible at a mid-range temperature so the joint does not start at its limit.
Order it as one package. Filler, backer rod, sealant, covers and waterstops are best quoted together so the components are compatible.

Where It Is Used
Common Questions
How do I size an expansion joint cover?
It is driven by the nominal joint width and the expected movement. Send us the joint width and whether it is trafficked and we will recommend a profile.
Do you supply waterstops for water tanks?
Yes. Centre-bulb PVC and rubber waterstops for both construction joints and movement joints, in standard widths. Potable-water approved grades are available on request.
Can you supply the full joint system from one order?
Yes — cover profile, filler board, backer rod, sealant and primer. Giving us the full detail means nothing is missing when the crew is on site.
What is the difference between an expansion joint and a control joint?
A control joint is a planned weak line that directs shrinkage cracking. An expansion joint is a full gap that allows the structure to expand and contract without stress.
Why is backer rod used behind sealant?
It sets the sealant depth and stops it bonding to the back of the joint, so the sealant can stretch properly instead of tearing.
