From soil preparation to the delivery of serviced construction platforms, Geotech Caraïbes handles the full range of earthworks operations across Saint-Martin and Sint Maarten with operational rigor and an in-depth knowledge of the island, built over ten years of local jobsites.
Earthworks are the fundamental first step of any construction project. Without rigorous soil preparation, no structure can be erected under satisfactory conditions of stability and durability. In Saint-Martin and Sint Maarten, this discipline takes on even greater importance owing to the island's distinctive geological features, its rugged terrain, and the specific tropical climate constraints of the Caribbean arc.
At Geotech Caraïbes, earthworks are far more than mechanical excavation. They are an integrated technical process, led by professionals who know every sector of the island, its soils, its water tables, and its topographical particularities. Led by David Pivetta, the company has amassed more than ten years of local jobsites in Saint-Martin — experience that no off-island player can replicate.
Earthworks encompass all the operations that reshape the natural relief of a site to make it fit to receive a building, a roadway, a platform, or any other built structure. This discipline covers several complementary types of work, which follow one another according to the nature of the project and the soil constraints:
Working the soils of Saint-Martin cannot be improvised. The island presents a geological diversity and a topographical complexity that demand in-depth field knowledge, acquired over the long term.
Volcanic soils and basaltic terrain: a significant portion of Saint-Martin's territory features rock formations of volcanic origin. These highly resistant grounds call for suitable heavy equipment — high-breakout-force hydraulic excavators, hydraulic breakers — and expert machine operation to avoid destabilizing the adjacent layers.
Clay soils and highly plastic zones: other sectors of the island, notably the valley bottoms and the areas bordering the lagoons, feature clay soils with a high water content. These expansive clays require specific treatment: preliminary drainage, and hydraulic lime or cement to improve the mechanical properties before compaction.
Coastal zones and instability risk: jobsites along the shoreline or near the lagoon are subject to particular constraints: coral sand, a near-surface water table, and the risk of undercutting. Geotech Caraïbes masters these environments and adapts its methods accordingly.
Hurricane season: from June to November, Saint-Martin is exposed to tropical hurricanes. Jobsites must factor in this constraint from the planning phase — securing the work areas, protecting open excavations, and storing equipment safely. Geotech Caraïbes's local expertise guarantees that climate risks are anticipated and that jobsites continue under the best possible conditions.
Rugged terrain: Saint-Martin is an island of pronounced relief, with many hills, steep-sided valleys, and significant level differences. Earthworks on sloping ground require mastery of slope-cutting, purging, and reinforcement techniques to prevent landslides.
Our earthworks expertise applies to a wide range of projects across the island:
Private villas and residences: every villa built in Saint-Martin begins with an earthworks phase. We carry out excavations, grading platforms, and general earthworks for residential projects of every scale, from single villas to residential complexes.
Residential subdivisions: servicing a subdivision begins with the general earthworks of the site — topsoil stripping, grading the roadways, the lots, and the common areas. Geotech Caraïbes supports developers and land developers from the first stripping pass through to the acceptance of the general earthworks.
Hotels and tourism developments: Saint-Martin hosts large-scale hotel projects. These jobsites require precise earthworks, often in several phases, with strict multi-trade coordination constraints. Our organization and responsiveness allow us to meet the demands of the most exacting project owners.
Public infrastructure: municipal roads, parking areas, public spaces, community facilities — the public sector regularly calls on our crews for large-scale earthworks, carried out in compliance with technical standards and contractual deadlines.
Industrial and logistics zones: storage platforms, maneuvering areas, warehouses — industrial and logistics sites in Sint Maarten and Saint-Martin require heavy earthworks with high demands for bearing capacity and flatness.
Delivering quality earthworks requires a high-performance equipment fleet available locally. Importing equipment from mainland France or neighboring islands entails delays and costs incompatible with the pace of Saint-Martin jobsites. Geotech Caraïbes owns, right here on the island:
This owned fleet, maintained and operational at all times, guarantees our responsiveness and our ability to mobilize the necessary resources without delay.
At Geotech Caraïbes, every earthworks jobsite follows a structured process that guarantees quality execution and compliance with the specifications:
Earthworks are rarely a standalone service. They fit into a logical sequence with site utilities and roadworks (VRD): once the general earthworks are complete, trenches for dry and wet utility networks can be opened, roadways can be profiled, and platforms can be equipped. Geotech Caraïbes ensures this continuity by managing both phases, which guarantees optimal coordination, the absence of conflicting interfaces between contractors, and a coherent overall delivery.

Our signature: a local signature, a professional standard.
The cost of earthworks in Saint-Martin depends on many factors: the nature and volume of material to be moved, the presence of rock, site accessibility, the haul distance for excavated material, and the project levels.

The duration of earthworks varies with the scale of the project. For a single villa, the general earthworks can be completed in two to five days. For a subdivision or a multi-unit project, timelines range from a few weeks to several months depending on the phases. We draw up a detailed schedule during the technical scoping, factoring in the weather and logistics constraints specific to Saint-Martin.
Depending on the scale of the work, various permits may be required: a building permit, a prior declaration, or a simple works declaration. For large earthworks, a preliminary geotechnical study may be required. Geotech Caraïbes helps you identify the necessary administrative steps and works in coordination with your architects and engineering firms.
Hauling off excavated material is a specific challenge in an island setting. The excavated soil is either reused as fill on the jobsite (in compliance with reuse rules) or hauled to approved disposal areas in Saint-Martin. Geotech Caraïbes has a network of local recovery channels and organizes haul-off in strict compliance with the environmental regulations in force on the island.
Yes, Geotech Caraïbes works across the entire island — the French side (Saint-Martin, 97150) as well as the Dutch side (Sint Maarten). Our team is used to working in both jurisdictions and masters the regulatory particularities of each. This dual capability is a unique asset for projects that straddle both parts of the island.
Hurricane season (June to November) calls for specific precautions. Geotech Caraïbes systematically factors climate risk into jobsite planning: protecting open excavations, securing equipment and material stocks, and providing temporary drainage of open work areas. In the event of a hurricane warning, our crews apply an accelerated securing protocol to limit risks and protect work in progress.
