Alicante Geotechnical Visor
Mechanical Performance & Strata
"Official IGME geological data translated into practical excavation conditions. Check ground hardness, groundwater depth, and rock-breaking requirements before mobilizing heavy machinery to your site."
Interactive Stratigraphic Map (IGME)
National Geological Cartography (MAGNA) allowing engineers, architects, and developers to evaluate the mechanical resistance of the terrain before deploying heavy machinery.

What Does Each Map Color Mean for Your Build, Pool, or Basement?
Geological maps use technical names like Quaternary, Keuper, or Mesozoic. Here is what they actually mean in plain English for your timeline, machinery, and budget:
1. Yellow / Beige Tones (Alluvial, Sands & Silts)
What it is: Soft soil, gravel, or loose sand (typical on coastal plains and valleys).
What it means for you: Fast, economical digging without rock-breaking. Watch out: near the coast or dry riverbeds, shallow groundwater may require pumping and trench shoring.
2. Red / Pink / Greenish Tones (Marls, Clays & Gypsum)
What it is: Expansive clay or marl that swells when wet.
What it means for you: Easy to dig, but requires proper drainage, deeper footings, and sulfate-resistant (SR) concrete if gypsum is present to prevent future cracking.
3. Blue / Grey / Purple Tones (Limestone & Dolomite)
What it is: Solid bedrock or hard caliche crust (common on hillsides and inland Alicante).
What it means for you: Very strong bearing capacity for foundations, but requires heavy excavators with hydraulic breakers—increasing pool or basement excavation time and cost.
IGME Operational Interpretation
Direct translation of the lithostratigraphic legend (folding structures, contacts, faults, and lithologies) to the mechanical realities of excavation and foundation.
Hard Carbonates & Dolomites / Anticlines
Massive Mesozoic (Jurassic/Cretaceous) limestone and dolomite outcrops common in northern and inland Alicante, with very high unconfined compressive strength.
- Operational Impact: Heavy wear on buckets and teeth. Direct bucket digging is not possible.
- Required Machinery: >30t Excavators equipped with heavy hydraulic breakers.
- Geotechnical Risk: Appearance of joints or fractures (Anticlines) destabilizing slopes.
Keuper Clays & Gypsum / Fault Zones
Upper Triassic facies. Frequently associated with mechanical contacts and thrust faults. Visco-plastic behavior.
- Operational Impact: Highly expansive clays. Critical risk for shallow foundations.
- Structural Requirement: Sulfate-resistant (SR) concrete mandatory due to gypsum.
- Safety: Strict trench shoring >1.5m due to local faults and cohesion loss.
Alluvial Fillings & Basins (Terraces/Glacis)
Quaternary superficial deposits (sands, gravels, silts, and marshes) predominant in the Alicante, Elche, and Vega Baja basins.
- Operational Impact: Soft ground (rippable). Fast progress with backhoe loaders.
- Geotechnical Risk: Shallow water table and high permeability (liquefaction risk).
- Required Machinery: Heavy pumping equipment (dewatering) and perimeter slope stabilization.
