The COCUS Heavy-Duty Pile Cage Spacers are high-performance circular wheel spacers engineered specifically for bored piling, diaphragm walls, and deep foundation reinforcement. When lowering a heavy steel pile cage into a drilled borehole, maintaining a consistent, uniform concrete cover is critical to protecting the rebar from groundwater corrosion and ensuring structural load capacity.

Designed with a heavy-duty clip mechanism, these wheel spacers snap securely onto the horizontal helical wrap or links of your pile cage. As the cage is lowered, the wheel rotates smoothly against the soil wall or steel casing, ensuring the steel frame remains perfectly centered without digging into or compromising the integrity of the borehole walls.

We offer our structural pile cage spacers in two distinct cover sizes to meet your specific geotechnical engineering specifications:

45mm Cover: Ideal for standard bored piles, smaller diameter foundation columns, and civil works with minimal aggregate clearance requirements.

75mm Cover: Engineered for large-diameter deep piles, marine environments, and aggressive ground conditions requiring substantial concrete cover to defend against water ingress.

Key Technical Features
Smooth Rolling Wheel Design: Features a free-spinning wheel configuration that rolls seamlessly down the borehole. This completely prevents the spacer from catching, scraping, or collapsing loose earth into the bottom of the pile.

Secure Heavy-Duty Clip Mechanism: Engineered with a rigid, high-grip central clip that locks aggressively onto the steel rebar. It is designed to withstand the severe vibrations and downward forces experienced during cage installation.

Excellent Concrete Flow Properties: The open-spoke design allows fluid concrete to pass freely through the wheel during the tremie pour, eliminating voids, air pockets, or honeycombing around the perimeter of the pile.

Robust Injection-Moulded Construction: Manufactured from high-density, non-corrosive polymers that possess high compressive strength. They will not crush or deform under the extreme lateral weight of a misaligned steel cage.

Time-Saving Installation: Rapid clip-on application completely eliminates the tedious task of wire-tying individual spacers, speeding up site preparation timelines significantly.

Material: High-Density Injection-Moulded Polymer (Non-Corrosive)

Available Cover Sizes: 45mm / 75mm

Rebar Compatibility: Fits standard reinforcement bar diameters from 5mm up to 16mm links

Configuration: Free-rotating wheel with integrated mechanical rebar locking clip

Application: Bored piling, continuous flight auger (CFA) piling, foundation columns, and retaining walls

1. Why use a wheel-style spacer instead of a standard concrete block or clip spacer for piles?

Standard static spacers or concrete blocks will slide against the borehole wall as the cage is lowered. In bored piles, this scraping motion digs into the soil, causing loose earth to cave into the bottom of the pile, which ruins the concrete base mix. A wheel spacer rolls smoothly, protecting the earth walls.

2. Will these spacers slip or slide down the rebar when hitting obstructions?

No. The central clip is molded with internal locking ridges that grip the ribs of the steel reinforcement firmly, preventing any vertical or horizontal slippage during installation.

3. Does the plastic material weaken the overall strength of the concrete pile?

No. Because the wheels feature an open-spoke profile, the wet concrete flows completely through and around them. They occupy a fraction of the structural area and form an tight, continuous bond with the surrounding mix.

4. Can these spacers be used with Continuous Flight Auger (CFA) piling?

Yes, they are highly recommended for CFA piles where the steel cage must be plunged directly into the pre-filled wet concrete column, as the wheel design minimizes resistance during insertion.

5. Can these pile cage spacers be clipped onto the main vertical structural rebar instead of the horizontal helical links?

It is highly recommended to clip these spacers onto the horizontal helical wrap or links (the transverse reinforcement) rather than the main vertical bars. When clipped onto the horizontal wires, the wheel rotates parallel to the downward motion of the cage as it is lowered into the borehole. If attached horizontally to a vertical bar, the wheel would be dragged sideways rather than rolling, which defeats the anti-scraping design and increases the risk of the spacer shearing off.
