Underwater drilled anchors

Features of the Temano® drilled anchoring system:

  • Pull-out resistance: 54 tons/anchor for the equivalent of 100kg of material
  • Works on all types of seabed
  • Reduces impact on the seabed 🌱
  • Ground pressure lower than human step pressure
  • Works with propylene glycol: colorless oil, water-soluble, and ocean-friendly
  • Lifespan: 50 years and more with duplex stainless steel

The steps to perform an underwater anchoring:

  1. Positioning
  2. Deployment of the drilling tripod
  3. Adjustment of the legs
  4. Drilling
  5. Injection of natural cement
  6. Anchor testing

The device

The drilling device is practically made up of a tripod, under which the drilling mast is suspended and articulated on a universal joint. This articulation ensures the verticality of the hydraulic hammer on uneven ground.

Once the desired drilling depth is reached, a slurry of natural PROMPT VICAT cement is injected under high pressure. The injected natural PROMPT VICAT cement rises from the bottom of the hole to the surface.

The significant roughness of the walls, combined with the specific threading of the steel bar, results in a highly resistant seal, proportional to the drilled length and the hardness of the layers crossed.

The natural PROMPT VICAT cement has the advantage of very rapid drying, being 100% naturally sourced, and of very high technical quality.

Resistance: up to 54 tons/anchor for pull-out.
