ProSolve Underground Warning Tape

Protect Underground Utilities and Prevent Costly Excavation Damage

ProSolve Underground Warning Tape is a highly visible, non-adhesive caution tape (Caution tape is a brightly colored, non-adhesive tape used to signal hazards and mark locations of buried utilities.) laid above buried cables, pipes, gas lines, and electrical cables to give excavators a clear visual warning before they reach the live service below.

This product is specifically designed for contractors, utility companies, civil engineers, and groundwork specialists who are responsible for the installation, maintenance, and protection of underground services. Preventing excavation damage is crucial for ensuring safety on site, minimizing costly repairs, and maintaining uninterrupted service continuity for essential utilities. Accidental strikes to buried services can result in severe injury, service outages, and significant financial loss, making proactive marking with underground warning tape an essential part of any excavation or construction project.

Used correctly during backfill, this underground warning tape assists contractors in identifying the location of underground services such as electric cable, gas, and water, helping prevent accidental damage, service disruption, injury risk, and costly repair work during excavation.

Why You’ll Love It

• Bright colour and bold warning text – The tape is designed to stand out underground, giving operators immediate caution before striking buried utilities.

• Helps reduce costly utility strikes – Underground utility warning tape marks the location of buried services such as electricity, gas, and water, helping to prevent accidental utility strikes during excavation work.

• Durable for long-term installation – Manufactured from weather-resistant polyethylene, including rot-resistant LLDPE, it is suitable for long-term underground use and maintains visibility in adverse soil conditions.

• Quick, non-adhesive installation – Simply lay the hazard warning tape during backfill above pipes, cables, or ducts; no adhesive, fixing, or specialist tool is required.

• Industry-standard colours – High-visibility caution tape is designed to be easily identifiable, often using industry-standard colour coding to indicate different types of buried services.

Caution tape types are distinguished by colour combinations, materials, and messages to signal specific hazard levels and regulatory requirements, making the right product essential for professional utility marking.

Let’s see what sets ProSolve apart from other warning tapes, and how it fits within our wider range of warning tapes and site safety supplies.

What Makes It Different

Most low-grade warning tapes fade, tear, or become hard to read after time underground.

ProSolve Underground Warning Tape is built differently:

• Rot-resistant LLDPE construction – Caution tape is often made from materials like Linear Low-Density Polyethylene, which is rot-resistant and suitable for long-term underground use.

• Clear, bold print – The warning text remains easy to review when uncovered, giving excavators the note they need to stop, locate, and proceed safely.

• Optimal 100mm width – A wider warning tape for underground cable provides strong coverage above the service, improving recognition during groundwork operations.

Detection capabilities of warning tapes can be either detectable, with a metal backing for excavators to find, or non-detectable, serving as a visual warning. ProSolve can help customers select the right underground electrical warning tape, electrical warning tape, or general utility tape for the application.

How It Works

Caution tape serves as a visual warning to prevent accidental utility strikes by marking the location of buried services such as electricity, gas, and water. By placing this tape above underground utilities, you create a proactive safety layer that alerts future excavators before they reach critical infrastructure.

1. Install during backfill
   Lay the underground warning tape approx 300mm above buried electrical cables, gas lines, water pipes, or telecom ducts. Buried warning tapes are placed in the soil above gas lines or electric cables to alert future excavators.

2. Create an early warning layer
   If excavation tools reach the tape, operators receive a clear visual warning before contacting the actual service. This assists in reducing accidental damage and helping teams identify the likely service location.

3. Stop, locate, and continue safely
   Bright colours and bold warning text alert excavators to stop digging, locate the exact utility position, and use safe excavation procedures before continuing.

Caution tape effectiveness is contingent on environmental conditions and the behaviour of individuals regarding compliance, so it should always be used alongside site plans, safe digging practice, and approved locating methods.

Now that you know how it works, let’s see who benefits most from using ProSolve Underground Warning Tape or the dedicated ProSolve underground warning tape for street lighting cables.

Who It’s For

Ideal for:

• Contractors and excavation companies working on construction sites

• Utility companies installing or maintaining underground electric, gas, and water services

• Civil engineers managing buried cables, telecom ducts, and drainage routes

• Groundwork specialists requiring reliable underground cable marking systems

Caution tape can serve varied purposes including marking construction sites, securing crime scenes, and managing public events. Adhesive caution tape is available in various materials, including fabric and PVC, and is used for marking temporary hazards and obstacles at construction sites and events, where maintaining hygiene with essential site cleaning and maintenance supplies is also important. Barrier tape, also known as route tape, is commonly used to cordon off hazardous areas and is available in various colours and patterns, such as red and white or yellow and black.

Frequently Asked Questions

Why use underground warning tape?

Underground warning tapes provide a permanent buried warning layer directly above the service. Surface marking, maps, and temporary barrier tape are useful, but underground tape remains in place to warn future excavators.

How long does the tape remain visible underground?

• Weather-resistant tapes made from polyethylene or PVC maintain visibility even in adverse conditions.

• ProSolve tape is designed for durability, clear warning text, and long-term underground safety.

What depth should warning tape be installed above utilities?

• As a general guide, install the tape approx 300mm above the electric cable, pipes, or buried services during backfill.

• Always follow project specifications and local requirements.

Which colours indicate specific utility types?

• Colour coding helps identify service type:

  • Yellow caution tape signals minor threats or general caution.

  • Red caution tape indicates immediate, severe threats to life or health, meaning stop and do not enter.

• Caution tape can also be paired with specific hazard signs to clearly outline types of danger.

Is caution tape only for underground use?

• No. Lightweight caution tape can be tied between posts, trees, or traffic cones for flexible use in various situations, including temporary event areas, hazardous areas, and site access control.
