Key Features and Benefits
Concrete-Encased Mechanical Protection
The EB-20 conduits are intended to be utilized to their fullest power when completely enveloped in concrete, thereby presenting a great deal of resistance to crushing, impact, and external pressure.
Electrical Safety
Grounding problems are removed and the probability of electrical faults is lowered because PVC is an insulator.
Corrosion & Moisture Resistance
PVC, unlike metal conduits, is not affected by rust and does not break down, even when it is surrounded by alkaline concrete or is in the soil moisture conditions.
Smooth Internal Bore
Guarantees that the cables can be pulled in easily without causing any damage; this applies even to longer conduit runs.
Heat Resistance
The performance of the system is kept unchanged still during the high temperature conditions found in Saudi Arabia and other Gulf Cooperation Council (GCC) countries.
Lightweight & Installer-Friendly
Reduces difficulties connected with the handling, transport, and site installation.
Long Operational Life
It will be ready to deliver decades of maintenance-free service that will, in turn, allow you to save on the lifecycle costs.

Installation Method (How It Is Used)
1. Site Assessment & Layout
Conduit routes are marked according to approved electrical drawings.
2. Surface or Trench Preparation
Formwork, slabs, or trenches are prepared before conduit placement.
3. Conduit Placement
PVC EB-20 conduits are laid securely in position with proper spacing.
4. Jointing
Conduits are joined using PVC couplers and solvent cement to ensure strong, leak-free connections.
5. Concrete Encasement
Concrete is poured fully around the conduit, embedding it securely.
6. Cable Installation
After curing, electrical cables are pulled smoothly through the conduit.
Accessories & Fittings
PVC couplers
45° and 90° bends
Junction and inspection boxes
Solvent cement
Spacers and fixing clips
