Void Detection
Identifying Hidden Subsurface Gaps
Void detection identifies subsurface gaps and anomalies beneath concrete, pavement, and structural elements. Non-destructive investigation methods are used to locate areas of potential concern without cutting, coring, or excavation.
Void Detection
When Conditions Are Unknown
Voids beneath slabs, pavements, and structures may develop due to settlement, material loss, or construction conditions. These subsurface gaps are not visible at the surface and can create uncertainty during maintenance, repair, or redevelopment activities.
Void Detection
Non-Destructive Subsurface Imaging
Void detection is performed using surface-based scanning methods that image subsurface conditions. Data is collected across defined areas to identify anomalies consistent with gaps or changes in material, without disturbing existing structures or surfaces.
Void Detection
Documented Subsurface Findings
Deliverables include mapped areas of interest, documented scan results, and supporting observations. Information is provided to support planning, coordination, and decision-making where subsurface conditions require further consideration.
Void Detection
Common Applications
Void detection is commonly applied where subsurface gaps may affect existing infrastructure or planned work activities.
Identify potential voids beneath floor slabs in industrial, commercial, or municipal facilities prior to repair or modification.
Detect subsurface gaps beneath pavement systems that may contribute to settlement or surface distress.
Assess subsurface conditions beneath foundations where access is limited and excavation is undesirable.
Void Detection
Investigation Methods Used
Void detection relies on non-destructive investigation methods to identify subsurface gaps and anomalies. These approaches provide internal visibility while preserving existing surfaces and structures.
Surface Scanning
Systematic scanning used to evaluate subsurface conditions across defined areas.
Subsurface Imaging
Non-invasive imaging used to identify anomalies beneath concrete and pavement.
Data Interpretation
Collected data reviewed to identify areas consistent with potential voids.
