THE ARCSTONE SYSTEM

More than a pile.
One complete system.

A continuous load path, from the building to the ground. Every component works together.

For lightweight structures

Cabins, decks, gazebos and lightweight timber or bamboo structures.

Typical helix
Ø240 mm
Shaft wall options
≈ 3 / 5–5.5 mm
ARC / 114
Ø114mm

Greater demands

Pools, heavier buildings and projects requiring additional capacity.

Typical helix
Ø300 mm
Shaft wall options
≈ 3 / 5–5.5 mm

Diameter alone does not define load capacity. The complete foundation is engineered for your project.

Arcstone manufactured screw pilesSTEEL / PROTECTION / LONGEVITY
TWO MATERIAL ROUTES

Made for the elements.

01

Factory-galvanized pipe

SPINDO galvanized steel pipe, approximately 3.0–3.2 mm wall. Fabricated helices, welds and exposed areas receive their specified protective coating.

02

Thick-wall steel + hot-dip zinc

Approximately 5–5.5 mm wall. Fabricated first, then hot-dip galvanized in Surabaya, with a target zinc thickness of approximately 90 µm, verified against the coating records.

Arcstone spider foundation assembly

Spider foundations

Driven steel pipes for suitable sandy ground, with a purpose-designed central connection.

Bolted bamboo interface

Custom structural interfaces

Connections for bamboo, timber, steel and designed concrete floor systems. Rock sites can be assessed for a separate expanding-anchor solution.

Pile lengths are for visualization only. Bearing depth must be established from soil and load data. Transparent terrain reveals the buried piles.

PRELIMINARY FOUNDATION CONCEPT

This visualization is generated for preliminary planning purposes only. Final pile spacing, pile diameter, pile length, helix configuration, steel grillage and reinforcement must be confirmed by Arcstone engineers based on the architectural design, structural loads, site topography and soil conditions.

THE PEOPLE BEHIND THE PILES

International experience.
Local by design.

ARCSTONE brings more than 15 years of international team experience to Indonesian construction. Our factory in North Bali makes complete screw pile systems, adapted to local ground, tropical weather and challenging access.

From analysis and fabrication to installation and final alignment, one team takes responsibility for the connected system. Bali is our starting point. Indonesia is our horizon.

Engineering evolves

From lighthouses and bridges to buildings, anchoring systems and slope applications across international markets.

15+ YEARS

Practical team experience

Experience in demanding climates, from freezing winters and seasonal temperature swings to hot, humid sites.

INDONESIA

A local next chapter

Made in Bali. Engineered for Indonesian sites. Local fabrication with a nationwide vision.

FROM FACTORY TO SITE

A clear process.
A connected team.

01

Assess & design

Soil, loads, topography and access define the foundation concept.

02

Fabricate & protect

Produce the piles, heads, channels and braces. Inspect the steelwork and coating.

03

Deliver & install

Set out the grid, install the piles and verify the project acceptance criteria.

04

Level & connect

Align the heads, assemble the grillage and complete the final inspection.

INSTALLATION EQUIPMENT

The right tools for the ground.

  • Electric screw pile driverRotational installation of helical piles.
  • Petrol-powered drilling rigPre-drilling and subsequent pile installation.
  • Impact hammerDriving steel pipes for spider foundations in suitable sandy soil.
TEST. VALIDATE. BUILD.

Confidence starts
with real data.

On-site vertical compression testing with equipment rated up to 50 tonnes. The test programme, reaction system and target load are engineered for each site. This is a testing capability, not a universal pile load rating.

Receive recorded load–settlement data, photos and engineering recommendations.
