We read the ground so you can
Geotechnical investigation and ASTM compliant material testing across Pakistan, turned into foundation recommendations your engineer can design against.
Trusted by institutions, contractors and developers across Pakistan
A foundation is only as good as the data under it.
Every structure transfers its load into soil that nobody can see. We make that soil visible: we drill it, sample it, test it, and hand you numbers with a method reference beside each one.
The output is not a stack of raw results. It is a report that states allowable bearing capacity, expected settlement, groundwater conditions, chemical aggressiveness and a clear foundation recommendation, ready for your structural engineer and your approving authority.
Fifteen disciplines, one accountable team.
Field investigation, laboratory testing and non destructive evaluation, delivered by the same people who write your report.
Borehole drilling
Rotary and auger boreholes advanced to design depth, with continuous logging and undisturbed sampling.

Soil & rock testing
Classification, shear strength, consolidation and permeability on samples preserved to represent true site conditions.
Read more
Plate load test
In situ bearing capacity and settlement measured directly under a known applied load.
Read more
Concrete testing
Cube and cylinder strength, workability and durability checks as part of structural quality control.
Read more
Pile integrity test
Low strain testing that confirms the length and continuity of cast in place and driven piles.

Chemical analysis
Sulphate, chloride and pH on soil and groundwater to grade the risk to buried concrete and steel.

Engineers, not just drillers
Certified geotechnical engineers and geologists interpret the data, so the recommendation is defensible.
Traceable to a standard
Every result carries its ASTM, BS or AASHTO reference and the calibration status of the instrument used.
Mobilised fast
Rigs and crews staged in Karachi, ready to move nationwide, with fieldwork typically starting within a week.
Safe, tidy sites
Disciplined site practice, proper spoil handling and minimal disruption to work already underway.
Serious equipment
Electronic cone penetration, downhole seismic, resistivity and NDT instruments maintained to specification.
Buildable advice
Recommendations written for the site as it is, so you save on foundations instead of over designing them.
Four steps, every time.
Structured so nothing is assumed and every number traces back to a sample and a method.
Scope the investigation
We review your site plan, structure type and loading, then propose a borehole layout, depths and test schedule.
Drill, log and sample
Crews mobilise, advance the boreholes, run SPT or CPT, log strata and seal samples for the laboratory.
Test in the laboratory
Classification, strength, consolidation and chemistry are run under controlled conditions with internal QA checks.
Report and support
You receive logs, results and a signed recommendation, plus an engineer on the phone to talk it through.
Not all soil is a problem. Some of it is a gift.
A quick tour of what sits under Pakistani sites, how each type behaves under load, and which foundation suits it.
Engineering tools you can use right now.
Estimate allowable bearing capacity, plan a borehole layout, classify a soil, size a concrete mix and convert pressure units. No sign up, nothing stored, works offline once loaded.
Open the toolkit
This is what your fee actually buys.
Real crews, calibrated instruments and a laboratory that runs the method as written.
