Surface Markers
Surface markers keep your underground utilities, pipelines, and property boundaries clearly identified above ground where crews, contractors, and the public can see them. Whether you need to mark a buried gas line, identify a cable route, or post a visible boundary, the right surface marker saves time, prevents accidents, and holds up for years in the field.
Tech Products has been manufacturing surface markers since 1948, and we build every product to last in real-world conditions. From high-visibility poly dome markers along roadsides to flexible cable and pipeline markers that spring back after a mower strike, our surface marking systems are trusted by utilities, municipalities, and pipeline operators across the country. We also carry a full range of related products including pole markers, cable tags, and pavement markers.
Poly Dome Markers
Poly Dome Markers are designed for high-visibility identification along roads, rights-of-way, and utility corridors. Each dome mounts to a sturdy white post, and both the dome and the post are UV treated for long-term outdoor performance.
Graphics are printed on both sides of the dome and chemically etched into the surface, so your message stays legible even after years of sun, rain, and wind exposure. Each dome stands 16″ high with a 3-1/2″ diameter, making it easy to spot from a vehicle or on foot.
Poly Dome Marker Specifications
- Dome Height: 16″ with a 3-1/2″ diameter
- Post Lengths: 6′, 7′, and 8′ (other lengths available on request)
- Post Wall Thickness: 0.2″ to 1.6″
- Dome Colors: Orange, Yellow, Green, or White
- Print Colors: Black and White
- Graphics: Chemically etched into both sides of the dome

Cable and Pipeline Markers
If you manage buried cable or pipeline routes, you know how important it is to have above-ground markers that stay visible and stay standing. Our Cable and Pipeline Markers are built from high-impact fiberglass reinforced thermoplastic that is specially formulated for UV protection. They are tough enough to handle direct hits from mowers and vehicles, yet flexible enough to bounce right back.
The uniquely designed symmetrical three-rib profile is the key. When something strikes the marker, it flexes on impact and returns to its original upright position. That means fewer replacements, less maintenance, and consistent visibility along your route.
For areas with especially heavy traffic or large commercial mowers, we also offer a lightweight, curve-shaped line marker made from specially formulated UV plastic. This design handles repeated impacts in high-traffic corridors where standard markers take a beating.
All copy and graphics can be custom made and applied to the marker before delivery, so your markers arrive ready to install with your specific identification, warnings, or branding.
Cable and Pipeline Marker Specifications
- Sizes: 4″ x 66″ and 4″ x 72″
- Colors: Orange, Yellow, White, Red, and Blue
- Material: High-impact fiberglass reinforced thermoplastic with UV protection
- Profile: Symmetrical three-rib design for flex-on-impact recovery
- Custom Graphics: Available on all markers
- Special Colors: Available on request
EVERLAST Ground Markers
EVERLAST Ground Markers are flat, stake-mounted markers built for permanent identification at ground level. Made from high-impact polypropylene with excellent cold impact resistance, these markers hold up in every climate and every season. UV protectors and antioxidants are added directly to the material, providing complete weather resistance without relying on surface coatings that can wear away over time.
Use them to mark buried utilities, property boundaries, easements, or any location that needs a visible, long-lasting ground-level identifier. The stakes keep them securely positioned, and the durable polypropylene construction means they will not crack, fade, or become unreadable.
EVERLAST Ground Marker Specifications
- Sizes: 5″ x 7″ and 5″ x 10″
- Material: High-impact polypropylene
- Weather Resistance: UV protectors and antioxidants built into the material
- Cold Impact Resistance: Excellent performance in freezing conditions

Frequently Asked Questions About Surface Markers
What are surface markers used for?
Surface markers are above-ground identification markers used to indicate the location of underground utilities, pipelines, cables, and property boundaries. They help utility crews, contractors, and excavators locate buried infrastructure before digging, which prevents costly damage and safety hazards. Common uses include marking gas lines, electric cables, water mains, fiber optic routes, and pipeline corridors.
What types of surface markers does Tech Products offer?
Tech Products manufactures three main types of surface markers. Poly Dome Markers are post-mounted domes for high-visibility roadside identification, available in 6′, 7′, and 8′ post lengths. Cable and Pipeline Markers are flexible fiberglass markers in 4″ x 66″ and 4″ x 72″ sizes that flex on impact and return upright. EVERLAST Ground Markers are flat, stake-mounted markers in 5″ x 7″ and 5″ x 10″ sizes for ground-level identification.
How long do surface markers last outdoors?
Tech Products surface markers are built for long-term outdoor use. All markers include UV protection built into the material itself, not applied as a surface coating. Poly Dome Markers use chemically etched graphics that resist fading and wear. EVERLAST Ground Markers include UV protectors and antioxidants added directly to the high-impact polypropylene, providing weather resistance in all climates including extreme cold.
Can I get custom graphics on surface markers?
Yes. All Tech Products surface markers can be customized with your specific copy, graphics, logos, and identification. Custom work is completed before delivery, so your markers arrive ready to install. Poly Dome Markers feature graphics chemically etched on both sides of the dome. Cable and Pipeline Markers accept custom graphics applied to the sign face. Special colors are also available on request. Call 1-800-221-1311 for custom orders.
What is the difference between a poly dome marker and a ground marker?
Poly Dome Markers are tall, post-mounted markers (6′ to 8′ above ground) designed for high visibility from vehicles and at a distance. They work well along roadsides, rights-of-way, and utility corridors. EVERLAST Ground Markers are flat, low-profile markers mounted on 12″ or 16″ stakes for ground-level identification. Ground markers are better suited for marking buried utilities, property lines, and locations where a tall post is not practical or necessary.
