Plastic Spacer 110 mm - 2 Way Base

Heavy-Duty Dual Duct Base Spacer for HDPE Conduits in KSA & Gulf Region

The Plastic Spacer 110 mm 2-Way Base is a strong and accurately made piece of hardware that is meant to hold two parallel 110 mm ducts in underground infrastructure installations. This spacer, as part of the duct bank system, helps to keep both pipes in the right position, safe, and above the ground, which in turn keeps them from getting deformed, sagging, or moving due to soil pressure or encasement in concrete.

In the KSA and GCC regions, including the UAE, Oman, Qatar, Kuwait, and Bahrain, the duct bank systems, which are stable for decades, are heavily relied upon by large-scale infrastructures such as telecom networks, power distribution systems, fibre optic backbones, urban utilities, and industrial facilities. The choice of duct spacers has become a critical factor due to the harsh climates, extreme temperatures, corrosive soils, and massive infrastructure expansions.

The Plastic Spacer 110 mm 2-Way Base is specifically designed for such extreme conditions. The product of UV-stabilized polymers and advanced injection-moulding technologies, it provides unparalleled reliability, dimensional accuracy, and endurance—even in the challenging environments of Riyadh, Jeddah, Dammam, Dubai, Abu Dhabi, Doha, Manama, and Muscat.

The Plastic Spacer 110 mm 2-Way Base is a dual-channel spacer designed for two ducts of 110 mm outer diameter. Being a base-type spacer, it sits directly on the trench bed or manhole floor, forming the first layer of support in a duct bank. Its primary goal is to hold both ducts at a specified separation, prevent contact between conduits and soil, and maintain uniform spacing for subsequent layers of intermediate or top spacers.

This product serves as a critical alignment tool, ensuring that both ducts remain perfectly parallel throughout the run. When used correctly, it improves performance during cable pulling, enhances structural integrity during concrete encasement, and reduces long-term maintenance risks.

For contractors and engineers in KSA & GCC, stability and alignment are crucial due to high soil temperatures, thermal expansion, and heavy vehicular loads. This spacer eliminates misalignment issues and provides long-term durability even under difficult field conditions.

Material Composition & Manufacturing

1. Raw Material (PP/HDPE)

The Plastic Spacer 110 mm 2-Way Base comes with the durability of either polypropylene (PP) or high-density polyethylene (HDPE) depending on the manufacturer’s choice. Manufacturers prefer using PP for its good rigidity, dimensional stability, and resistance to chemicals. Conversely, HDPE is mainly used where high impact resistance is a must.

2. Additives

The mixture of polymers consists of UV stabilizers, heat stabilizers, anti-oxidants, mineral fillers (optional), and color masterbatch pigments--impact modifiers that help the product have a long life in the Middle East. These additives make certain that the spacer will not only be stable in the middle of the desert but also withstand the extreme conditions of sun exposure, sandstorms, or outdoor storage for a long time.

3. Production Process

  • The precision and repeatability of the process are guaranteed through injection moulding.
  • Cooling, trimming and finishing operations are done to ensure smooth edges.
  • Reinforced ribs add strength especially for load-bearing applications.
  • Dimensional QC (Quality Control) guarantees perfect duct fit.
  • Each batch undergoes both visual inspection and mechanical testing.

How the Plastic Spacer 110 mm 2-Way Base Is Used

Below is the step-by-step process used across major Gulf infrastructure projects.

1. Trench Preparation

  • Ensure the trench floor is level

  • Add bedding sand (typically 50–100 mm)

  • Remove sharp debris or rocks

2. Placement of Base Spacers

  • Place Plastic Spacer 110 mm 2-Way Base directly onto the prepared bedding

  • Align spacers in straight line using string or laser guidance

  • Maintain 0.8 m to 1.2 m spacing (engineer’s specification)

3. Laying Ducts

  • Place both 110 mm ducts into the dual channels

  • Ensure ducts sit firmly and evenly

  • Check alignment using laser or straight edge for long runs

4. Installing Higher Layers (if required)

If building a multi-layer duct bank, install:

  • Intermediate spacers

  • Top spacers

These lock into the 2-way base for vertical stacking.

5. Securing & Encasement

  • Backfill carefully or pour concrete

  • Ensure ducts do not shift during compaction

  • Maintain cover and spacing as per approved drawings

6. Final Inspection

Check:

  • Alignment

  • Levels

  • Spacer integrity

  • Correct spacing intervals

This ensures long-term performance without duct collapse or uneven settlement.

Applications in KSA & GCC

Best Industry Practices for Installing 110mm 2-Way Base Spacers

  • Level and compact the trench bedding before the base spacers are placed.
  • Both conduits must be completely seated into the spacer grooves.
  • Verify alignment along the length of the trench before intermediate layers are applied.
  • Use approved HDPE or PVC conduits that are rated for 110mm.
  • Inspect prior to backfilling or before encasing with concrete.

Correct installation will minimize:
