Site utilities & roadworks in Saint-Martin —
Servicing your projects from A to Z.

Site utilities & roadworks in Saint-Martin: technical expertise at the heart of every project.

Site utilities and roadworks (VRD) form the technical backbone of any development project. They transform raw land into a serviced, connected, accessible plot that complies with regulatory requirements. In Saint-Martin and Sint Maarten, VRD takes on a particular complexity tied to the island setting, the island's dual administrative status, and the climate constraints of the Caribbean.

Geotech Caraïbes handles the entire VRD chain, from opening the trenches to the final roadway restoration. This ability to manage the whole cycle without subcontracting the critical phases is a guarantee of quality, consistency, and controlled timelines. Led by David Pivetta, the company brings an in-depth knowledge of the territory and operational rigor to every jobsite.

What is VRD?

The term VRD covers two closely linked major families of work:

Roadworks refers to all circulation infrastructure: carriageways, internal subdivision roadways, driveways, parking areas, curbs, and gutters. It encompasses the foundation courses, the base courses, and the surface finishes (asphalt, concrete, pavers).

Utility networks comprise all the buried networks needed to make land or a development serviceable — both wet utilities and dry utilities.

Wet utilities: water, sewerage, stormwater

Wet utilities carry fluids — drinking water, wastewater, stormwater — and form the vital arteries of any development:

• Wastewater networks (EU): collecting and conveying domestic or industrial wastewater to treatment plants. In Saint-Martin, sewerage constraints are heightened by the environmental sensitivity of the receiving environments (the lagoon, the Caribbean Sea). Our crews dig the trenches, lay the wastewater pipework in PVC or HDPE, and make the connections in accordance with the technical specifications.
• Stormwater networks (EP): collecting and discharging rainwater. In Saint-Martin, tropical rainfall generates large peak flows — particularly during hurricane events or convective downpours. Stormwater networks must be sized accordingly and, where necessary, include retention or infiltration structures.
• Drinking water networks (AEP): laying drinking water supply pipework, connections to the public distribution networks, and installing meters and shut-off valves. Drinking water quality in Saint-Martin is an absolute priority, and our work complies with all health specifications.

Dry utilities: power, fiber, telecom

Dry utilities gather all the buried energy and communication networks:

• Low- and high-voltage power: ducts, chambers, cabling. Undergrounding power networks is a growing requirement in Saint-Martin, both for aesthetic reasons and for resistance to hurricanes.
• Fiber optics and telecom networks: laying ducts and draw chambers for electronic communications networks. The rollout of ultra-high-speed broadband in Saint-Martin relies on this underground infrastructure work, which Geotech Caraïbes carries out with precision.
• Public lighting: ducts and cabling to power street light columns and roadway lighting systems, in coordination with the local network operators.

Internal roadways: from foundation to surface

The internal roadway of a subdivision or an industrial site comprises several successive courses, each with a precise technical role:

• Capping layer: compacted granular material ensuring the bearing capacity of the pavement on the supporting soil
• Foundation and base course: bituminous or untreated aggregates depending on the expected traffic and the loads to be supported
• Wearing course: hot-mix asphalt, concrete, or pavers depending on architectural and functional specifications
• Curbs and gutters: defining the carriageways and channeling runoff toward the collection structures
• Road markings: pavement markings, crosswalks, parking zones

The specifics of VRD in Saint-Martin and Sint Maarten

The dual administrative status: Saint-Martin is divided between a French side (an overseas collectivity, 97150) and a Dutch side (Sint Maarten, a constituent country of the Kingdom of the Netherlands). The technical regulations, the network operators, and the connection procedures differ by jurisdiction. Geotech Caraïbes has a full command of both regulatory environments and can work on either side of the border seamlessly.

Island logistics: the supply of materials (pipework, ducts, chambers, aggregates, asphalt) must be planned carefully. Import lead times can be significant. Our network of local suppliers and our knowledge of the supply channels guarantee a continuous supply with no jobsite interruption.

Intense rainfall and hurricanes: tropical rains, sometimes very heavy, can disrupt open-trench work. We plan our operations taking weather forecasts into account and set up temporary protections to limit the impact on work in progress. During hurricane season, our securing protocols keep jobsites running.

Protecting the lagoon and natural environments: the Saint-Martin lagoon and its surroundings are classified as environmentally sensitive zones. VRD work near these areas requires particular precautions — turbidity barriers, discharge monitoring — and strict compliance with the environmental requirements of the local authorities.

Types of VRD projects in Saint-Martin

Residential subdivisions: complete servicing of the lots, internal roadways, and wastewater/stormwater/drinking-water/dry-utility networks. Geotech Caraïbes supports developers and land developers from the feasibility study through to the handover of networks to public operators, ensuring the compliance of the works at every stage.

Villas and private residences: individual connections from the public networks, trenches under driveways or roadways, and installation of the connection structures. Clean, fast work with no nuisance for the neighborhood.

Hotels and tourism complexes: Saint-Martin's hotel projects require oversized VRD networks to meet water and energy demand. Our crews build high-performance networks within controlled timelines, in coordination with architects and engineering firms.

Business parks and industrial sites: heavy-duty roadways sized for trucks, high-capacity networks, and industrial water management systems compliant with environmental regulations.

Public facilities and municipal roadways: in partnership with the local authorities of Saint-Martin, Geotech Caraïbes carries out VRD work on public spaces, municipal roadways, and community facilities, in compliance with public procurement rules.

Our approach: coordination and end-to-end control

The success of a VRD jobsite rests on rigorous coordination of the sequence of tasks. At Geotech Caraïbes, we manage this coordination from end to end: trench excavation, network laying, backfilling, compaction, and roadway restoration. This end-to-end control avoids interference between trades and guarantees the quality of the interfaces.

Our close ties with our expertise in earthworks and sewerage & drainage allow seamless work on complex projects, with no loss of time or quality at the junctions between phases. From soil preparation to the delivery of serviced construction platforms, Geotech Caraïbes ensures the technical continuity of your project.

Guarantees and acceptance of VRD works

On delivery of each VRD jobsite, Geotech Caraïbes hands over a complete as-built package: drawings of the installed networks (as-built), leak-test results for the pipework, compaction reports for the backfilled trenches, and technical data sheets for the materials used. These documents form the technical record of the works and make future maintenance or modification easier.

For subdivision or public development projects, we coordinate the procedures for handing over the networks to the public operators (water, sewerage, power, telecom) and ensure that all reservations are cleared within the agreed timeframe.
