Look into the earth
before you build on it.
Raysense screens ground conditions before design freeze — seismic hazard, liquefaction potential, subsurface stratigraphy and soil response — so developers, EPC contractors and public agencies commit capital to sites that can actually carry the load.
Insurance pays after the damage. Screening prevents it.
Both are risk management. Only one of them stops the loss from happening.
Insurance
- Pays out after a structural or seismic event has already caused damage
- Premiums rise once claim history or hazard exposure is known
- Does not change what's built or where — only who absorbs the cost
- Deductibles, exclusions and claim disputes sit between you and recovery
Site screening
- Identifies liquefaction risk, weak strata and seismic hazard before foundation design
- Feeds directly into IS 1893-compliant PSHA/DSHA and structural sizing
- Lets you re-site, re-design or budget for ground improvement early — when it's cheap
- Produces a defensible technical record for lenders, insurers and regulators
Prevention has no deductible.
Six methods, one picture of the ground
Each service answers a different question about what's beneath a site. Combined, they build a single, code-referenced risk picture.
PSHA / DSHA
Probabilistic and deterministic seismic hazard analysis — hazard curves, uniform hazard spectra and design PGA per IS 1893.
MASW
Multichannel analysis of surface waves for shear-wave velocity profiling and Vs30 site classification.
ERT
2D electrical resistivity tomography to map lithology, groundwater and weathering profiles beneath a site.
GPR
Ground-penetrating radar for shallow subsurface imaging — utilities, voids, fill boundaries and buried features.
Liquefaction assessment
SPT-based liquefaction potential index (LPI) mapping and susceptibility classification for seismic zones.
Hazard zonation
AHP-weighted GIS overlay combining seismicity, faults, soil and topography into a composite suitability map.
Built for the people who carry the risk
Real estate developers
De-risk site acquisition and design freeze with ground truth before capital commitment.
EPC contractors
Firm up foundation design inputs and reduce variation-order exposure mid-construction.
Renewable energy firms
Assess ground conditions for solar, wind and grid infrastructure sites, often in undercharacterized terrain.
Government & public agencies
Support code-compliant, defensible technical bases for infrastructure and lifeline structures.
From regional hazard to a site decision
A staged screening approach narrows from broad regional seismicity down to a clear suitability call — before detailed PSHA/DSHA and geotechnical investigation begin.
Regional seismicity
Evaluate regional activity using earthquake catalogues and zonation maps.
Fault proximity
Check distance to active faults and seismogenic sources.
Ground motion
Estimate expected PGA using empirical relationships.
Site conditions
Assess near-surface geology, soil class and groundwater.
Risk screening
Combine factors via AHP-GIS into a suitability index.
Decision
Classify as suitable, conditionally suitable, or not suitable.
