The extra weight for concrete anchors, reached by adding our heavy weight natural aggregate MagnaDense, will improve the protection and stability of your anchoring product. It allows to increase the concrete density up to 4 t/m3.

Various forms of concrete anchoring

Precast concrete anchors among others prevent undersea currents from dislodging pipelines from their bedding in the sea. Anchoring comes in many shapes and sizes such as:

  • Concrete weight coating for pipelines
  • Concrete mattresses
  • Concrete blocks/anchors for tidal energy devices
  • Erosion and coastal protection
  • Protection covers
  • Crossing bridges

Depending on your project the required weight for your anchor differs. With over 50 years of experience in supplying high density aggregate to the concrete industry, we can help you define the right concrete mix for you. Feel free to contact our sales team for additional information or a sample of our different MagnaDense grades.

Advantages of MagnaDense concrete sea anchors

Concrete undersea anchors made with high density concrete have two main functions:

  1. place a protective barrier around valuable installations
  2. keep installations at the seabed and protect them from buoyancy forces

Besides adding weight to your concrete mix with MagnaDense, manufactured from the natural iron oxide Magnetite, it is:

  • Harmless to the environment
  • Non-reactive to seawater
  • Abrasion resistant
  • Increasing the underwater lifetime for concrete

All of which make the LKAB Minerals’ product range of MagnaDense a natural fit for your concrete anchor production process.
