Rock Retaining Walls (Escollera)
Hillside Plot Stabilization Across Alicante
"We build heavy limestone rip-rap retaining walls (muros de escollera) using hydraulic rock grapples, compacted footings, geotextile membranes, and perforated drainage pipes. Gain flat usable garden or pool terraces on steep Costa Blanca plots."
Gravity Stone Engineering with Our Own Heavy Fleet
Steep coastal and hillside plots in Busot, Mutxamel, El Campello (Coveta Fumá), Finestrat, and Altea require engineered earth retention. Unlike solid concrete walls that trap hydrostatic pressure, a properly built limestone escollera wall works by gravity, drains stormwater naturally, and blends naturally into Mediterranean landscaping.
Retaining Wall & Slope Stabilization Services
- Gravity Rockery & Dry-Stone Retaining Walls (2m to 6m High): Interlocking quarry limestone boulders seated on reinforced strip footings or solid bedrock—built as a natural stone retaining wall without mortar trapping water.
- Hydrostatic Backfill Drainage: Non-woven geotextile separation membrane, washed gravel drainage wedge, and perforated land-drain pipes to prevent DANA storm saturation.
- Villa Terracing & Pool Platforms: Turning steep sloped plots into flat, usable terraces for swimming pools, driveways, and garden areas.
- Erosion & Access Road Protection: Reinforced rock embankments for rural tracks, boundary lines, and stormwater channels with direct quarry haulage.
