MANTA RAY® utility anchors are driven into the ground from ground level, with standard hand-held equipment or with a mounted breaker on a skid steer, backhoe, or other equipment. There is no need for digging holes and no soil disturbance during installation making it perfect for tight and hard-to-reach locations like backyards, alleys, etc. The anchors are made from galvanized ductile iron which offers maximum corrosion resistance.

The utility anchor system is designed to out perform current anchoring systems in:

– Field tested holding performance
– Speed of installation
– Installation in hard-to-reach locations
– Total install cost

No More Guess Work

The MANTA RAY system is a cost-effective anchoring solution in comparison to other screw or expandable systems because it installs quickly without large expensive equipment. MANTA RAY is fully guaranteed with an unconditional replacement policy if the anchor breaks during installation. The MANTA RAY is NRECA accepted.

No more guesswork! Installation and testing of the MANTA RAY anchor is simultaneous.

Typical Civil Construction Applications

Civil engineers chose MANTA RAY earth anchors to provide a variety of application uses, easy installation and ultimate holding capacity.

Block Walls: MANTA RAY tie backs allow minimum excavation for mechanically stabilized earth walls. This allows block/geogrid walls to be installed where excavation is not possible.

Seawalls: The anchoring of seawalls with MANTA RAY anchors eliminates expensive and complicated tie-back methods. Minimal, if any, excavation is required. 

Sheet Pile: MANTA RAY earth anchors provide overturning stability for the sheet piling versus structural piles driven into the bedrock. Cost savings can be substantial.

Pipelines: The compact and portable installation equipment allows MANTA RAY to be installed in locations normally inaccessible to traditional earth anchor methods.

Structures: As a specified supplier to the US Military, MANTA RAYS are specified to anchor rapid deployment relocatable structures and portable fabric structures.

Others: Timber Walls, Foundation Stabilization, Excavation Shoring, etc.

Erosion Control Applications

Revetment Mat: MANTA RAY anchors provide critical points of anchoring stability on stream and shorelines to prevent water erosion using cellular concrete revetment matting. The anchors install easily through the openings in individual blocks. This system prevents lifting of mats and dangerous erosion under extreme flood conditions.

Reno Mattress: MANTA RAY earth anchors are used to anchor Reno Mattresses on sites where less depth and more surface area protection is required. Reno Mattresses are often used as flexible foundation slabs under gabions or may also be used as channel linings and revetment mats. 

Timber Walls: Rather than conventional timber deadmen, MANTA RAY anchors are used to provide proof loaded tie backs to insure permanent structural integrity with minimal excavation.

Gabions: The flexibility of the MANTA RAY system allows gabions to be installed on steep slopes. MANTA RAY anchors also stabilize embankments that are in need of repair and facilitate slop stabilization by securing geogrids, geotextiles and fiber mats.

Others: Log Revetments, Root Wads, etc.

The Manta Ray Advantage

The compact and portable installation equipment allows MANTA RAY earth anchors to be installed in locations normally inaccessible to traditional earth anchor methods making it the ideal anchoring solution for specialized applications.

• Environmentally Friendly
• No Excavation
• Easy Installation
• Fast, Simple Installation (saves money!)
• Simultaneous Installation and Proof Testing

Specialized Applications Include

Scaffolding: MANTA RAY anchors are used to secure and support scaffolding for building projects worldwide.

Foundation Stabilization: MANTA RAY anchors are used to stabilize structurally compromised (failing, bowing or buckling) residential and commercial foundations.

Temporary Structures: A specified supplier for the Military. From inflatable air domes to  large rapid deployment relocatable structures and other devices, MANTA RAY anchors provide rapid installation and secure holding.

MANTA RAY marine anchors are designed to drive into the ground at any desired angle. The anchor is driven into the ground by hydraulic hand-held jackhammers (breakers). There is no soil disturbance upon installation, as the soil around it is compacted when the anchor is driven. Installation and testing of MANTA RAY anchors is simultaneous.

The marine anchor system is designed to out perform current anchoring systems in:

– Field tested holding performance
– Speed of installation
– Total install cost

Mooring, Pipelines and Floating Docks

Floating Docks and Moorings: From the Great Barrier Reef to the Red Sea, MANTA RAY anchors are used to anchor moorings that help protect coral reefs and other natural resources. Now there is an environmentally friendly anchor system that installs easily underwater with conventional equipment for buoys, floating docks, man made reefs and more.

Pipelines: Prevent movement of underwater pipeline with the MANTA RAY anchor. Simple installation procedures equate to significant time and cost savings.
