In today’s construction, precision matters. A concrete spacer makes sure your steel reinforcement maintains this accuracy. It holds the steel in place while concrete is poured, giving you proper cover over the bars. In turn, your structure becomes stronger and lasts longer.
At AHM BMT, we provide top-quality concrete spacer solutions for construction professionals. As a trusted Dubai supplier, we serve contractors and builders throughout the UAE, supporting quality, accuracy and strength in all construction projects. We supply them for slabs, columns, walls, foundations and more.
Whether building a high rise in Dubai or a large industrial complex in the UAE, a quality concrete spacer is vital to a structurally sound building.
What Is A Concrete Spacer?
A concrete spacer is a small construction accessory which keeps the reinforcement steel a certain distance from the formwork surface. The distance that the spacer provides is called the cover. The cover to the steel keeps the reinforcement bars away from moisture, air, so as corrosion which would lead to damage over the years. Concrete cover is a very important factor in how long a building is likely to stand.
Why The Concrete Spacer Is So Important In Construction
Maintaining the Proper Concrete Cover
Concrete spacers keep reinforcement steel the appropriate depth within the poured concrete structure. The amount of concrete that should surround the reinforcement is called cover. This cover protects the steel from environmental conditions such as corrosion as well as direct damage from the exterior. Correct cover greatly contributes to the durability of a reinforced concrete structure. The correct placement of spacers is a key element to ensure site standards are maintained and engineering specifications are met across construction in Dubai and the UAE.
Improving Structural Durability
The overall integrity of any reinforced concrete structure depends on accurate reinforcement positioning. Concrete spacers hold the steel reinforcement at the correct position throughout the concrete pouring phase, and they can help to avoid steel reinforcement movement during this process. Correct positioning will increase the load capacity of the slabs, columns and beams of any structure and will help to avoid structural weaknesses and cracks forming over years to come.
Preventing Steel Corrosion
Corrosion of steel reinforcement can significantly reduce the structural lifespan of a reinforced concrete structure. The protection of reinforcement steel against corrosion by the use of concrete spacers is crucial as this keeps it fully embedded within concrete so as preventing access to moisture and air. In Dubai and the UAE, this is even more crucial due to the extreme temperature and humidity ranges that are expected year-round, which can accelerate corrosion even further.
Uses of the Concrete Spacer
Concrete Spacer for Slab Reinforcement Work
In construction of reinforced concrete slabs, it is not only important that the mesh or bars of the reinforcement do not rest directly on the shuttering but also rise above the required level after pouring. Concrete spacers will keep the steel at the correct height both from the surface below it and the height above it, thus guaranteeing the required cover is present over the entire reinforcement mesh. This is critical for good quality floor systems for residential and commercial use.
Concrete Spacer for Column and Beam Reinforcement
For column and beam reinforcement, it is critical that the bars remain at the correct position within the concrete volume, not shifting out of position during pouring and solidifying. A concrete spacer can hold each of the bars and also the inner cage of vertical bars at the appropriate distance from all surfaces of the shuttering and maintain correct spacing between all parts of the internal reinforcement cage. This is important to ensure structural integrity and correct bonding between the steel and concrete.
Concrete Spacer for Foundations
Reinforced concrete foundations can benefit significantly from the correct positioning of steel reinforcement using concrete spacers. This will provide effective cover to prevent corrosive conditions being transmitted from the ground or from atmospheric conditions penetrating the concrete cover. Proper concrete cover will ensure strong, lasting foundations, and can assist with any structural movement from the ground beneath.

Concrete Spacer for Walls
Reinforced concrete walls and retention walls also benefit from the careful use of concrete spacers when constructing a structural wall section. The alignment and proper cover of each of the bars in the vertical sections of RCC walls is important to provide excellent structural integrity over the entire surface area of the wall and ensure a good quality finished surface is achieved without a visible reinforcing cage outline.
Types of Concrete Spacers
Plastic Concrete Spacers
These are generally inexpensive and are popular among builders and contractors working with slabs and wall reinforcement work. Plastic concrete spacers have many benefits in terms of their light weight and quick placement during building. Their accuracy of concrete cover is always ensured due to the variety of spacer types being produced, meaning the cover specified by the engineer is always met without question.
Wheel Spacer
The wheel spacer is designed for columns and wall frames that use vertical reinforcing bar. The concrete wheel spacers provide even coverage for each part of the internal reinforcement bars throughout the volume of the wall or column to be constructed. These typically fix to the bar in question without the need for any tying or securing method.
Concrete Cover Blocks
Concrete cover blocks are manufactured from cement based material and tend to be stronger than a plastic alternative. They are therefore very useful where structural integrity during construction is critical. Because they match the same composition of the poured concrete there is no possibility of different materials having the effect on the integrity or structural strength that differing compounds might have. They are most often used in heavily reinforced structural frameworks where there may be some pressure on the cover from structural forces.
Bar Chair Spacer
A bar chair spacer is specifically used for reinforcing in slabs, to create cover above the base layer of reinforcement to the upper layer of reinforcement mesh or bar. They help to keep these two sections of the reinforcement separated to maintain correct and consistent spacing above the lower cage or layer of bar reinforcement used.
