Okay, this sounds like a recipe for trouble and potential hazards. Let's break down why this is problematic

The Issues:
Buried Cable/Splice

Burying a cable and splice without the proper protection is a huge problem. The constant contact with the surrounding soil can lead to corrosion and degradation of the cable and splice insulation over time. This can cause short circuits, ground faults, and even electrical fires.

Non-Direct Burial Rated Splice

The biggest red flag. Splices not rated for direct burial are NOT designed to withstand the moisture, chemicals, and pressure of being underground. They will corrode and fail rapidly. This will lead to intermittent power, complete power loss, and serious safety hazards.

Paver Stones as Backfill

While paver stones themselves might be inert, they are not a suitable backfill material for electrical work. Sharp edges of the stones can damage the cable insulation over time, especially with ground movement. Pavers provide poor drainage. Pavers do not provide any kind of physical protection for the cable.

2 ft Under a Slab

Being under a slab makes access for repair extremely difficult and expensive. This creates an unnecessary safety risk.

Why This is Dangerous



Shock Hazard

The degraded insulation can create a path for electricity to flow to the ground, making the surrounding area live and posing a serious shock hazard to anyone who comes into contact with the ground or any conductive material nearby.

Fire Hazard

A short circuit or ground fault can generate significant heat, potentially igniting surrounding materials and starting a fire.

Equipment Damage

The improper wiring can damage any equipment connected to the circuit.*

Violation of Electrical Codes

This installation almost certainly violates local and national electrical codes (like the NEC in the US). This can result in fines and legal issues.

What Needs to Be Done (IMMEDIATELY)


Turn off the Power

The very first thing you need to do is

IMMEDIATELY TURN OFF THE POWER to the circuit feeding this cable. Use the appropriate circuit breaker or fuse. This is crucial for safety.2. Contact a Qualified Electrician

Do NOT attempt to fix this yourself unless you are a qualified and licensed electrician with experience in underground electrical work. This is a dangerous situation that requires professional expertise.3.

Explain the Situation

When you contact the electrician, clearly explain what you found: the buried cable, the non-direct burial splice, the paver stones, and the location under the slab.4.

Expect Repair/Replacement

The electrician will likely recommend replacing the entire cable run with properly rated direct burial cable and making a proper direct burial splice in an accessible location (ideally above ground in a weatherproof junction box). This may involve digging up the slab or finding a new path for the cable. They might also recommend GFCI protection for the circuit to provide an additional layer of safety.

In summary, this is a hazardous and non-compliant installation that needs to be addressed by a qualified electrician as soon as possible. Do not use the circuit until it has been properly inspected and repaired. Flag for review
