Who we are
GarBia Group — registered as GarBia Structural and Geotechnical Solutions and also known as GarBia SGS — is a geotechnical engineering and construction services company based in Cainta, Rizal. Since 2018 we have carried out soil investigation, geotechnical testing, and foundation works for residential, institutional, and government projects across Luzon.
What we do
Site assessment, sub-surface soil exploration by SPT, coring and test pits, soil laboratory testing, detailed geotechnical reports with foundation design recommendations, and micropiling, bored piling, and grouting works.
Field teams operate throughout Metro Manila, Rizal, and the wider Luzon area. Recent investigations include projects in Antipolo, Marikina, Pasig, and Taguig.
ISO 9001:2015 certified, DPWH-BRS accredited, PCAB Category “A” licensed, PhilGEPS Platinum member, and an ASTM organisational member — our laboratory equipment and test methods follow ASTM standards.

Geotechnical & Construction FAQs
Common questions about soil investigation, foundation engineering, and construction services in the Philippines.
GarBia provides soil investigation, site investigation, laboratory testing, foundation engineering, deep foundations, micro-piling, and pile driving support for residential, commercial, and government projects across Luzon.
The soil carries the building, not the other way round. A soil investigation establishes bearing capacity, groundwater level, and the depth and strength of each layer below the site, so the foundation can be designed for the ground that is actually there. Skipping it means designing on assumption — which shows up later as differential settlement, cracked slabs, or a foundation that has to be redesigned mid-project at far greater cost.
SPT is the most common in-situ test in soil investigation, carried out to ASTM D1586. A split-spoon sampler is driven into the bottom of a borehole by a 63.5 kg hammer falling 760 mm. The number of blows needed to drive each 150 mm increment is recorded, and the blows for the second and third increments give the N-value. That N-value correlates with the soil's density and strength, and it also recovers a disturbed sample for laboratory classification.
It depends on the footprint, the structure type, the loads, and how variable the ground turns out to be — a small residential lot on uniform ground needs far less than a mid-rise on reclaimed or mixed fill. The number and depth are agreed after a site assessment rather than fixed in advance, because the point of the investigation is to cover the ground the structure will actually sit on. Describe your site and structure and we will advise on a scope.
Very much so. The Philippines sits on the Pacific Ring of Fire, and seismic design depends on knowing the soil profile: site classification, and whether loose saturated sands below the water table could liquefy under cyclic loading. Liquefaction analysis is part of a geotechnical report for exactly this reason — it tells the structural designer whether the ground will keep its strength during shaking.
Yes. GarBia Group serves clients throughout Luzon and the Philippines with field teams for site investigation and foundation works. Completed projects include work in Antipolo, Marikina, Pasig, and Taguig, and the office is in Cainta, Rizal.
