About the firm

MRD LLC is a Puerto Rico-based geotechnical contractor founded in 2005 and headquartered in Manati. Owned and operated by civil engineers with more than 20 years of experience, MRD specializes in design-build solutions for challenging geo-structural conditions across Puerto Rico, its municipalities, and neighboring Caribbean islands including Trinidad and Tobago. It delivers cost-effective, technically sound engineered solutions from early design through construction execution in ground improvement, deep foundations, soil reinforcement, excavation shoring, slope stabilization, and related geotechnical work. MRD has established strategic alliances with Tensar International, Geopier, International Construction Equipment (ICE), Rev-Drill, and International Drilling Equipment (IDE).

Capabilities

Deep Foundations

Design-build installation of drilled shafts and piles for building and infrastructure foundations.

  • Drilled Shafts / Drilled Piers

    Cased or uncased shaft installations with diameters ranging from 18 to 96 inches.

  • Auger-Cast Piles

    CFA pile installations with diameters ranging from 14 to 30 inches for deep structural support.

  • Micropiles

    High-capacity, small-diameter drilled and grouted piles used for structural support in restricted access areas or difficult ground conditions.

  • Vibratory Pile Driving

    Installation of steel H-piles and pipe piles using advanced vibratory hammer systems.

  • Expander Body Solutions

    Specialized foundation support systems designed to expand soil-pile contact area for increased load-bearing capability.

Ground Improvement

Engineered solutions for stabilizing soft, weak, or liquefiable soils to support shallow foundations.

  • Geopier Ground Improvement Technologies

    Proprietary rammed aggregate pier solutions designed to reinforce poor soils and control settlement under structural loads.

  • Liquefaction Mitigation

    Geotechnical stabilization methods designed to prevent soil strength loss during seismic events.

Soil Reinforcement

Geosynthetic and geogrid systems deployed to reinforce subgrades and stabilize slopes, retaining structures, or pavements.

  • Tensar Soil Reinforcement Technologies

    Integration of advanced geogrid technology to enhance load-bearing capacity and subgrade stabilization.

  • Uniaxial Geogrid Reinforcement

    Geogrid solutions designed primarily for high-strength reinforcement in retaining walls and steep slopes.

  • Biaxial and Triaxial Geogrids

    Multi-directional stabilization systems utilized to distribute heavy loads across pavements and weak subgrades.

  • InterAx Geogrid Systems

    Advanced geogrid solutions designed to optimize aggregate confinement and enhance pavement performance.

Excavation Shoring

Temporary and permanent retention structures designed to stabilize vertical cuts and protect adjacent properties during deep excavations.

  • Secant Pile Walls

    Overlapping concrete pile walls providing both structural support and groundwater cutoff.

  • Tangent Pile Walls

    Closely spaced concrete pile walls utilized for soil retention when groundwater control is not primary.

  • Soldier Pile and Wood Lagging Walls

    Classic earth retention systems utilizing vertical steel beams and horizontal timber lagging.

  • Soil Nailing

    In-situ reinforcement technique using steel tendons grouted into pre-drilled holes to stabilize steep slopes or excavations.

  • Sheet Piling

    Interlocking steel sheet driving for continuous earth retention and water exclusion.

  • Jet Grouting

    High-velocity fluid injection to erode and mix soil with cement slurry, creating high-strength underground grout columns.

Slope Stabilization

Geosynthetic and geogrid-reinforced methods to address unstable slopes, riverbanks, and roadside embankments, including landslide remediation.

  • Riverbank and Landslide Remediation

    Specialized slope repairs and erosion control measures along waterways and transportation corridors.

MSE Retaining Walls

Mechanically stabilized earth structures engineered for transportation, commercial, and infrastructure applications using modular block or welded wire basket systems.

  • Modular Block Wall Systems

    Interlocking modular blocks combined with geogrid reinforcement for durable and aesthetic retaining structures.

  • Welded Wire Basket Systems

    Steel wire basket structures filled with stone or vegetated soil for rapid, flexible retaining walls.

Equipment Rental

Provision of specialized heavy construction equipment with operators or as bare rentals for foundation projects.

  • Rev-Drill Mast Rentals

    Provision of heavy-duty drilling mast systems for vertical drilling and pile installations.

  • ICE and APE Vibratory Hammers

    Rental of high-power vibratory hammers designed for driving steel sheet piles, H-piles, and casing.

Geosynthetic Material Distribution

Distribution of advanced civil engineering geotextiles and geogrid stabilization products throughout the Caribbean region.

  • Tensar Geogrid and Geotextile Distribution

    Local supply of uniaxial, biaxial, triaxial, and InterAx geogrids and engineered geotextiles.
