What SOL STRUCTURE Groupe does

SOL STRUCTURE Groupe is a French geotechnical engineering and structural diagnostics consultancy that operates as the engineering arm of Groupe AccesSOL, a privately held French conglomerate aggregating specialized firms in post-disaster structural rehabilitation and substructure work. The firm delivers a four-pillar service portfolio: geotechnical studies (G1 preliminary, G2 conception, G5 diagnostic) aligned with the NF P 94-500 standard and France's Loi Elan mandatory-study regime; in-depth soil analysis and risk assessment covering mechanical, geological, and chemical characteristics including ground movement, erosion, and liquefaction; in-house geomechanical laboratory testing for soil and rock characterization (resistance, permeability, compressibility); and structural engineering services including digital-modeling-based dimensioning, verification, and concrete structure diagnostics. Its operating geography is concentrated in Île-de-France, with the parent group providing cross-entity synergy into construction and rehabilitation workstreams.

The firm serves two primary customer segments. Individual homeowners (particuliers) acquire G1 preliminary studies as a pre-sale obligation under Loi Elan for constructible land in clay shrinkage-swelling risk zones. Construction professionals (professionnels) — developers, builders, and contractors — require G2 conception studies for new builds, extensions, elevations, and rehabilitation projects. G5 studies are positioned for existing structures or post-disaster scenarios. The revenue model is professional-services, project-based, and quote-driven, with no publicly disclosed pricing, typical 4–6 week delivery timelines, and a 48-hour inquiry response commitment enforced through the corporate website.

Customer acquisition relies primarily on the solstructure.fr corporate website, which combines educational content on Loi Elan with quote-request forms segmented by customer type. No public social profiles, app presence, or external sales channels are disclosed. Ownership is exercised through the AccesSOL parent conglomerate rather than venture capital, private equity, or public markets.

Core offering

SOL STRUCTURE Groupe is a French geotechnical engineering consultancy that performs soil studies and structural diagnostics for property transactions and construction projects. It offers G1 preliminary, G2 conception, and G5 geotechnical studies (per NF P 94-500 and the Loi Elan framework), in-depth soil and risk analysis, structural dimensioning and verification, concrete structure diagnostics, and geomechanical laboratory testing. Its deliverables are targeted at individual property owners needing compliance studies and at construction professionals needing foundation design and risk assessment.

Product overview

SOL STRUCTURE Groupe est un bureau d'études géotechniques français proposant une gamme intégrée de services d'études de sol et de diagnostic structurel. L'offre s'articule autour de quatre piliers principaux : les études géotechniques G1, G2 et G5 (conformément à la norme NF P 94-500 et la Loi Elan), l'analyse approfondie des sols et risques associés, le dimensionnement et vérification de structures, le diagnostic des structures en béton, et les essais géomécaniques en laboratoire. Ces services sont conçus pour fonctionner de manière complémentaire, permettant une évaluation complète des risques géotechniques depuis l'analyse préliminaire jusqu'à la conception des fondations et le suivi des ouvrages.

Products and services

• G1 Preliminary Geotechnical Studies (Études Géotechniques G1 (Préalables)) Site studies and general construction principles to identify major ground risks for the sale or purchase of constructible land, delivered in compliance with the Loi Elan framework. Target audience: individual property owners, sellers, and buyers in clay-soil risk zones in France.
• G2 Conception Geotechnical Studies (Études Géotechniques G2 (Conception)) Pre-construction conception studies that precisely define foundations and stability measures for new builds, elevations, and extensions. Typical delivery timeline of 4-6 weeks. Target audience: construction professionals executing projects in at-risk zones.
• G5 Geotechnical Studies (Études de Sol G5) Soil studies conducted at any stage of a construction project on existing structures, or before repair works after a disaster, to secure and prevent risks. Target audience: property owners and construction professionals handling rehabilitation or post-disaster work.
• In-depth Soil and Risk Analysis (Analyse Approfondie des Sols et Risques Associés) Evaluation of geological, mechanical, and chemical characteristics of terrain to identify risks such as ground movements, erosion, and liquefaction phenomena, conducted via soundings and sampling. Target audience: construction professionals and property owners requiring detailed soil characterization.
• Structural Dimensioning and Verification (Dimensionnement et Vérification de Structures) Structural dimensioning and verification services combining innovation and compliance with applicable standards, using advanced modeling tools to guarantee resistance, stability, and durability of structures. Target audience: construction professionals, developers, and builders.
• Concrete Structure Diagnostics (Diagnostic des Structures en Béton) In-depth diagnostics of reinforced concrete structures to detect anomalies, evaluate material condition, identify degradation causes (cracks, reinforcement corrosion, environmental alterations), and propose solutions to extend service life. Target audience: property owners, facility managers, and construction professionals.
• Geomechanical Laboratory Testing (Essais Géomécaniques en Laboratoire) Full range of geomechanical tests to characterize soil and rock properties, including determination of resistance, permeability, and compressibility, conducted in laboratory or in situ. Target audience: construction professionals and property owners requiring laboratory confirmation of soil parameters.

Quantifiable outcome

• 4-6 weeks typical delivery time for geotechnical studies (G1/G2)
