Infrastructure & Ground Stability

Analyzing how terrain transformation influences placement requirements, foundation stability, and long-term viability of petroleum-support installations

Infrastructure-Terrain Relationship

Understanding how operational activity changes ground conditions that affect infrastructure performance and placement decisions.

Storage Systems

Fuel tank placement on disturbed terrain requires assessment of ground stability, settlement risk, and long-term foundation performance under loaded conditions.

Containment Infrastructure

Secondary containment berms and spill prevention structures depend on stable ground conditions and predictable settlement patterns to maintain integrity.

Support Equipment

Temporary structures, pump stations, and support equipment require level, load-bearing surfaces that resist differential settlement and erosion.

Ground Condition Assessment

How operational activity alters soil properties relevant to infrastructure placement.

Compaction & Load-Bearing Capacity

Soil compacted by operational traffic exhibits increased density and altered load-bearing characteristics. While compaction may improve surface stability for light loads, it can create zones of differential bearing capacity adjacent to undisturbed areas—leading to uneven settlement of structures spanning both zones.

Deep compaction creates hardpan layers resistant to natural water infiltration and root penetration. These layers may provide stable foundation surfaces but require assessment of long-term performance and potential for delayed settlement as moisture conditions change.

Settlement Risk Analysis

Disturbed soil zones with layer mixing, organic material burial, or loose fill material require consolidation time before stable foundation conditions develop. Placing heavy infrastructure on incompletely settled ground risks structural movement, connection stress, and containment system failure.

Field testing documents current soil density and identifies zones requiring additional compaction, stabilization, or extended consolidation periods before infrastructure placement proceeds. Comparing disturbed versus undisturbed zone properties reveals differential settlement potential.

Freeze-Thaw Behavior

In Canadian climates, altered soil moisture content and changed drainage patterns in disturbed zones influence frost penetration depth and freeze-thaw cycle impacts. Compacted soil with reduced infiltration capacity may maintain higher moisture levels—increasing frost heave susceptibility beneath infrastructure.

Understanding soil thermal behavior following disturbance informs foundation depth requirements and frost protection measures for permanent or semi-permanent installations.

Erosion Susceptibility

Infrastructure placed on erodible slopes or near newly formed drainage channels faces long-term stability concerns as erosion progressively undermines foundation support. Mapping erosion risk zones guides placement decisions and identifies locations requiring protective measures or stabilization before installation.

Infrastructure Placement Considerations

Specific terrain-related factors for different installation types.

Fuel Storage Tanks

Critical factors:

  • Foundation stability: Uniform load-bearing capacity across tank footprint to prevent differential settlement and connection stress
  • Levelness requirements: Maintaining horizontal orientation within tolerance limits as ground conditions change seasonally
  • Settlement prediction: Understanding long-term consolidation behavior of disturbed soil beneath loaded foundations
  • Erosion protection: Ensuring surrounding terrain remains stable and doesn't undercut foundation support
  • Drainage management: Directing water away from foundation zones to prevent saturation and loss of bearing capacity

Containment Berms

Critical factors:

  • Material compaction: Achieving specified density in berm construction material to prevent seepage and structural failure
  • Foundation conditions: Building containment structures on stable substrate that won't settle unevenly or fail under loaded conditions
  • Water resistance: Understanding soil permeability and designing for containment integrity during potential spill events
  • Long-term stability: Predicting how constructed berms will perform through freeze-thaw cycles and vegetation establishment
  • Erosion resistance: Protecting berm surfaces and foundations from progressive degradation

Access Surfaces

Critical factors:

  • Base stability: Compacted subgrade capable of supporting vehicle loads without rutting or failure
  • Drainage design: Preventing water accumulation that reduces bearing capacity and accelerates surface degradation
  • Material requirements: Selecting surface materials appropriate to underlying soil conditions and expected traffic loads
  • Seasonal performance: Maintaining access during spring thaw when bearing capacity naturally declines

Equipment Positioning

Critical factors:

  • Level surfaces: Creating stable platforms that resist settlement under equipment weight
  • Load distribution: Understanding soil capacity to support concentrated loads from equipment feet or pads
  • Operational accessibility: Maintaining stable access routes that don't degrade under repeated use
  • Safety considerations: Ensuring equipment remains stable during operation without ground subsidence or tipping risk

Stability Assessment Methods

Field and analytical techniques for evaluating ground conditions and infrastructure placement suitability.

Penetration Testing

Measuring soil resistance to penetration documents compaction levels and identifies layers of varying density that could cause differential settlement beneath infrastructure.

Soil Sampling

Laboratory analysis of collected samples determines moisture content, density, shear strength, and consolidation characteristics relevant to bearing capacity calculations.

Settlement Monitoring

Installing benchmarks and monitoring vertical movement over time documents actual settlement behavior and validates predictions of long-term stability.

Load Testing

Applying controlled loads and measuring surface deflection provides direct evidence of ground bearing capacity under conditions approximating infrastructure loading.

Permeability Assessment

Measuring how quickly water infiltrates disturbed soil informs drainage design requirements and predicts moisture-related stability changes.

Visual Inspection

Documenting surface features—cracking, erosion, vegetation stress, water accumulation—provides qualitative indicators of ground condition changes.

Infrastructure Planning Support

Site Selection Optimization

Ground stability mapping identifies zones within operational areas that offer superior foundation conditions—guiding infrastructure placement toward naturally stable terrain or previously compacted surfaces rather than recently disturbed zones.

Comparative analysis of different layout configurations reveals options that minimize infrastructure placement on problematic ground while maintaining operational efficiency and safety access requirements.

Foundation Design Input

Soil condition assessment data informs foundation type selection (surface pad, deep piles, reinforced slabs) based on actual ground properties rather than assumed conditions.

Understanding disturbance depth and lateral extent guides foundation sizing to distribute loads to competent soil layers beneath disturbed zones or span across differential settlement zones.

Timing Considerations

Infrastructure placement timing affects long-term performance. Installing heavy structures immediately after ground disturbance risks ongoing settlement as soil consolidates. Waiting for consolidation periods (months to years depending on conditions) reduces settlement risk but delays operational readiness.

Our analysis documents actual consolidation timelines observed in similar conditions—enabling realistic project scheduling that balances operational needs with infrastructure stability requirements.

Risk Mitigation Strategies

Approaches for managing terrain-related infrastructure risks.

Ground Improvement

Controlled recompaction, soil replacement, or stabilization additives improve bearing capacity in problematic zones—enabling infrastructure placement on otherwise unsuitable ground when alternative locations aren't available.

Foundation Reinforcement

Engineered foundations distributing loads to deeper stable strata, bridging over disturbed zones, or flexibly accommodating differential settlement where ground improvement isn't feasible.

Drainage Management

Engineered drainage systems preventing water accumulation around foundations, protecting against saturation-induced bearing capacity loss, and controlling erosion near infrastructure.

Monitoring Programs

Ongoing settlement and stability monitoring enabling early detection of adverse performance trends—allowing corrective measures before infrastructure failure occurs.
