Foundation Types We Execute

01

Pad & Chimney Foundations

Reinforced concrete pad and chimney foundations for self-supporting lattice towers. Designed per IS 2911 for normal to medium soils.

M20 to M30 grade concrete
Fe 500D reinforcement
Stub setting with ±3mm precision
Anti-corrosion treatment
02

Pile Foundations

Bored cast-in-situ pile foundations for poor bearing capacity soils, waterlogged zones, and expansive black cotton soil areas.

Bored piling 300mm–600mm dia
Minimum pile depth 6–12m
Load test as per IS 2911
Pile cap with chimney
03

Rock Anchor Foundations

Grouted rock anchor systems for hilly terrain and exposed rocky strata where conventional excavated foundations are uneconomical.

Rock quality assessment
Percussion drilling
Cement grouted anchors
Pull-out testing
04

Earthing & Substation Civil

Counterpoise earthing, plate/pipe earthing, grid earthing (substation), control room plinths, equipment pedestals, cable trenches, drainage.

GI pipe earthing 3m depth
Earth resistance testing
Control room civil works
Cable trench & drainage
Execution Method

Step-by-Step Site Process

1

Route survey support & tower spotting assistance

2

Excavation (manual/mechanized) & dewatering

3

PCC (1:4:8) → reinforcement & formwork

4

Stub/template alignment ±3mm tolerance

5

RCC (M20/M25) pour with vibrators

6

Curing 7–14 days → backfilling & compaction

7

Earthing installation & resistance testing

Applications
132kV

Single and double circuit T-lines

220kV

State transmission backbone

400kV

Interstate grid strengthening

765kV

National grid UHVAC corridors

Engineering Inputs

Soil data (SBC, strata, water table)
Tower schedule & leg loads (compression/uplift/shear)
Foundation drawings & rebar schedules
Earthing design documents

Deliverables

Completed foundations (as-built levels)
Cube test reports (7 & 28 day)
Bar bending schedule compliance records
Earthing resistance test certificates

QA/QC & KPIs

Slump 75–100mm, cube tests
Cover blocks, rebar spacing checks
Alignment & verticality checks for stubs
1–2 foundations/day/crew · Rework < 2%
