Geotechnical Solutions
Piling Systems
Helical pile and micropile solutions for deep foundation support, structural underpinning, retrofit foundation improvement, and load transfer into more competent bearing strata — including limited-access and existing-structure conditions.
Deep Foundation Support
Transfers structural loads into deeper, more competent soil or rock when near-surface support is insufficient.
Retrofit-Friendly
Well suited for improving support conditions in existing structures without full foundation replacement.
Helical + Micropile Options
Two distinct systems that can be matched to soil conditions, access constraints, and load requirements.
Limited-Access Capable
Both systems can be installed in constrained or low-headroom conditions where conventional piling cannot reach.
overview
When the structure needs more support, the answer is often deeper below grade
Strucproof piling systems include both helical piles and micropiles — two complementary approaches for transferring structural loads into deeper or more reliable ground. Both are well suited for retrofit conditions, new construction on challenging sites, and situations where conventional driven piles or drilled shafts are impractical due to access, vibration, or site constraints.
Helical piles are steel shafts with welded helical plates that are mechanically screwed into the ground — producing minimal vibration, requiring no excavation, and providing immediate load-bearing capacity upon installation. Micropiles are small-diameter (typically 5–12 inch), high-strength steel-cased piles that are drilled and grouted into place — offering high load capacity in a compact footprint, even in dense, rocky, or variable subsurface conditions.
Together, these systems give Strucproof the flexibility to address a wide range of foundation support needs — from tank foundations and structural underpinning to uplift resistance, infrastructure retrofit, and settlement mitigation.
Good fit when:
the challenge
Not every support problem can be solved at the surface
When an existing structure no longer has the foundation support condition it needs — or when a new structure must be built on ground that cannot reliably carry the intended loads — the solution often requires transferring load to a deeper, more competent zone. Surface repair, grouting, or soil improvement may help in some cases, but when the issue is depth-to-competent-bearing, the structure needs a pile.
Common foundation support challenges
- Settlement or differential movement under existing structures
- Insufficient bearing capacity in near-surface soils
- Need to retrofit or supplement an existing foundation
- Uplift forces from hydrostatic pressure, wind, or seismic loading
- New construction on poor or variable subsurface conditions
- Constrained access that prevents conventional driven-pile methods
Why piling systems matter
- They shift the support strategy deeper into the ground
- They can be integrated with existing structural systems
- They work in limited-access, low-headroom, or vibration-sensitive conditions
- They can address both compression and tension (uplift) loads
- They support targeted retrofit work rather than full reconstruction
- They offer immediate or rapid load-bearing capacity
Piling Methods
Two systems, matched to different conditions and objectives
Strucproof offers both helical piles and micropiles. The right choice depends on the soil condition, load requirement, access constraint, and whether the project is new construction, retrofit, or emergency stabilization.
SYSTEM 01
Helical Piles
Steel shafts with factory-welded helical bearing plates, mechanically screwed into the ground using rotary hydraulic equipment. No excavation, no spoils, no curing time — the pile is load-ready immediately upon installation.
How they’re installed
The pile is advanced by rotating the shaft into the soil. The helical plates pull the pile downward — much like a screw into wood — until the required torque and depth are achieved in the target bearing stratum.
Key advantages
- Immediate load-bearing capacity — no cure time
- Minimal vibration and noise
- No excavation or spoils produced
- Can be installed in limited-access and low-headroom conditions
- Removable and reusable in some applications
- ISO 9001 manufacturing; ASTM A153 galvanization available
Typical uses
- Foundation underpinning and retrofit
- Tank and equipment foundations
- Uplift and tension resistance
- Tieback anchors and soil retention
- Temporary or permanent structural support
SYSTEM 02
Micropiles
Small-diameter (typically 5–12 inch), high-strength, drilled and grouted piles that transfer structural loads through steel reinforcement and grout bonded to the surrounding soil or rock. Ideal for challenging subsurface conditions.
How they’re installed
A hole is drilled to the design depth. Steel reinforcement (casing and/or threaded bar) is placed, and cementitious grout is pumped under pressure to bond the pile to the surrounding ground. The pile cap or connection is then constructed.
Key advantages
- High load capacity in a compact, small-diameter footprint
- Effective in dense, rocky, or highly variable soils
- Minimal site impact — low vibration, limited spoils
- Can be installed at any angle (vertical, battered, horizontal)
- Can carry both compression and tension loads
- Well suited for retrofit, underpinning, and seismic upgrade
Typical uses
- Structural underpinning of existing buildings
- Foundation support for new construction on poor soils
- Seismic retrofit and lateral resistance
- Infrastructure support (bridges, piers, utilities)
- Slope and mass stability enhancement
How It Works
Provide a deeper, more reliable support path for the structure above
Whether helical or micropile, the objective is the same: transfer structural loads from the existing or planned structure into deeper, more competent ground so the foundation can perform as intended.
Step 01
Assess the support need
Determine where the existing (or planned) foundation support is insufficient. Identify the target bearing stratum, the required load capacity, and any access or environmental constraints.
Step 02
Select the piling approach
Choose between helical piles, micropiles, or a combination based on soil conditions, load path, access constraints, and structure type. Define pile layout, depth, and connection details.
Step 03
Install and connect to the structure
Install the piles to the specified depth and load-verify using torque correlation (helical) or grouting and load testing (micropile). Construct the pile cap or bracket connection to transfer loads from the structure into the piles.
Step 04
Improve long-term foundation performance
With loads transferred to deeper, more reliable ground, the structure benefits from improved stability, reduced settlement risk, and better long-term bearing performance.
Key Benefits
Structural support where it’s needed most
Transfers load to competent ground
Bypasses weak or unreliable near-surface soils and delivers load directly into more capable bearing strata below.
Retrofit-friendly installation
Both helical and micropile systems can be installed within or adjacent to existing structures — without demolishing and rebuilding the foundation.
Works in limited-access conditions
Small equipment footprint and flexible installation angles make both systems suitable for low-headroom, interior, and constrained-access locations.
Handles both compression and tension
Can resist downward structural loads as well as uplift forces from hydrostatic pressure, wind, or seismic loading.
Minimal site disruption
Low vibration, limited spoils, and no large-scale excavation — critical for occupied buildings, active facilities, and urban environments.
Rapid load-bearing capacity
Helical piles are load-ready immediately. Micropiles can be loaded shortly after grouting — minimizing foundation downtime.
Typical Applications
Where piling systems may be considered
Piling is most relevant where existing foundation conditions need improvement, where new construction requires deeper support, or where access, vibration, and environmental constraints limit the use of conventional driven-pile methods.
Foundation Underpinning
Existing structures where settlement, support loss, or increased loading requires supplemental foundation capacity without full reconstruction.
Tank & Equipment Foundations
Industrial settings where tanks, vessels, or heavy equipment need deeper support — including ring-beam connections and helical pier arrays.
New Construction on Poor Soils
Sites where near-surface soils cannot reliably carry the planned structural loads and deeper bearing is required.
Seismic Retrofit & Lateral Resistance
Structures requiring improved load paths and lateral resistance to meet updated seismic code requirements.
Uplift & Tension Resistance
Conditions where hydrostatic, wind, or seismic forces create uplift that must be resisted by a deep anchor system.
Infrastructure & Bridge Support
Bridges, piers, retaining walls, and utilities where foundation improvement or scour mitigation is needed in constrained conditions.
