Main business line

High-density aggregates
for demanding infrastructure

We produce amphibolite armourstone and aggregates from our own Lamas-Rapadoiro Quarry in San Sadurniño (A Coruña, Spain). The real density of the rock — above 3.10 T/m³ — makes it especially suited for offshore marine works where the piece must remain stable under Atlantic current and wave loading.

All production is carried out with our own fleet under System 2+ factory production control, with CE marking at source and a Declaration of Performance (DoP) available for every batch.

Applications

Where density matters
across marine works

01

Offshore wind farms

Scour protection of monopile and jacket foundations. High density reduces the volume needed for the same stabilising weight.

02

Submarine cables

Protection and ballast of HVDC interconnections and export cables. Filter and armour layers with armourstone classified under EN 13383-1.

03

Breakwaters & port works

Primary and secondary armour layers in rubble-mound breakwaters, jetties and reclamation fills for port platforms.

04

Coastal defence

Reinforcement of coastal stretches against erosion and storm surges, especially on the Atlantic coast.

05

Concrete aggregates

Graded aggregates classified under EN 13242 for applications requiring high density or strength.

06

Ballast layers

Aggregates for railway and road infrastructure under the relevant sectoral standards.

From Lamas-Rapadoiro
to the seabed

The whole value chain stays under HSS control: extraction at the Lamas-Rapadoiro Quarry, crushing and classification with our own fleet, storage and shipping from the Outer Port of Ferrol when the destination is marine. No middlemen, no production subcontracting.
