Geotechnical & geological investigation · since 1992
Ground truth, 600 metres down.
Rock core drilling, grouting and drifting for hydro power projects across the Himalaya, Bhutan and West Africa. If a dam, tunnel or bridge is going in, we tell you what the rock underneath is actually doing.
What we do
Find out what’s down there.
Then fix it.
Nine services across three stages of a project — reading the ground, treating it, and reaching water. Most clients start with investigation and come back for treatment.
Investigation
Reading the rock before anything is built on it.
Diamond core drillingWire line, non-core and DTH percussion. EX to HQ core sizes. Geophysical investigationSeismic refraction and electrical resistivity imaging. Borehole loggingLithology, dip and strike, RQD, core recovery, lugeon value. In-situ testingSPT, pressuremeter to 80 bar, dilatometer to 300 bar, flat jack. Plate load testingVertical settlement and strength in all soils, fills and rock.Treatment
Sealing, strengthening and opening the ground.
GroutingCurtain, stage, contact, consolidation, jet and polyurethane. Drifting & aditsSmall tunnels in any rock or strata, charge tuned to hardness. PilingDriven tubular piles, 350 mm to 1500 mm diameter. Slope stabilisationRock bolting and shotcrete on cut faces and abutments.Water
Deep wells where the table sits far down.
Tubewell boringDeep tubewells to 600 m in any hydro-geological setting.Plant & equipment
85 rigs. Owned, not hired.
Everything on site belongs to us, which is why we can mobilise into a Himalayan valley without waiting on a rental yard. Full inventory available on request.
On site
The work, as it happens.
Where we’ve worked
45 projects, mostly
above 1,500 metres.
Tehri, Nathpa-Jhakri, Kol Dam, Rohtang, Mangdechhu. Bar widths show completed projects by region.
Who we are
A partnership firm
that stayed technical.
Rawel Singh & Company was formed on 1 April 1992 and has spent 34 years doing one thing: soil and rock investigation by whatever drilling method the ground demands. We work directly for the authorities building India’s hydro capacity — NHPC, SJVNL, THDC, NTPC — and for the contractors delivering it.
Our in-house laboratory is equipped to international standard for physico-mechanical characterisation of soil, rock and rock joints, so sampling and testing stay under one roof and one chain of custody.
