Solinjection

What Solinjection does

Solinjection, founded in 2000 and headquartered in Paris, is a France-based specialist construction services company providing patented polyurethane resin and mineral-gel injection solutions for ground remediation and structural repair. Its core technical platform is a portfolio of six branded, registered solutions: MAGELLAN® (a 100% mineral gel for treating clay soil sensitivity to moisture, co-developed and patented with IFP Energies Nouvelles), SOIL COMPACTING® (expansive resin injection for deep soil consolidation to ~10 meters), RENFORSLAB® (slab lifting at the slab/soil interface without demolition), RENFORJOINT® (low-expansion resin for industrial slab joint 'pianotage' stabilization), RENFORVOID® (cavity and void filling for emergency or permanent use), and TRAITEMENT DE FISSURES PLUS® (combined crack repair and resin injection for foundation footings). The company is QUALIBAT 1263 certified for soil consolidation and holds PROVADEMSE INSAVALOR environmental safety validation under H14 criteria.

The company delivers services via a fleet of 10–19 tonne equipped service trucks deployed from 11 regional offices across metropolitan France, with intervention radii of 80 meters (extendable to 150 meters). Revenue is generated through quote-based, project-priced professional services for residential, commercial, industrial, and emergency response applications. Customer acquisition is dominated by referral channels — formal partnerships with major French insurers (AXA, Allianz, Groupama, MACIF, MAAF, Crédit Mutuel, AREAS, MMA, SMABTP) and a network of construction damage expert firms — supplemented by direct quote requests via the company website, newsletter communications, and industry-event presence (e.g., Vivatech).

Solinjection operates as a privately held SARL (share capital €50,000) within the privately owned Groupe Tabatabai (also referenced as Groupe TALENSIS), which itself operates subsidiaries including Déterminant® and LCS® under an RSE/decabonization commitment aligned with the UN Global Compact. The business is regulated under French decennial guarantee insurance standards, with SMABTP providing assurance décennale coverage for all Solinjection procedures. The company's competitive positioning rests on non-destructive methods, days-not-weeks execution, and the ability to operate in occupied residential and active industrial sites without disrupting end users.

Products and services

• MAGELLAN® clay soil treatment A 100% mineral gel solution developed in partnership with IFP Energies Nouvelles for treating clay soil sensitivity to hydric variations, addressing drought-related damage. Reduces shrinkage-swelling of clays (RGA) through a patented soil impregnation process for residential, commercial and public infrastructure clients.
• SOIL COMPACTING® soil consolidation Non-destructive soil consolidation solution using expansive polyurethane resin injection to increase soil bearing capacity. Treats depths up to 10m using SOIL COMPACTING NR® resin via injection techniques that avoid hydrofracturing or soil cracking, for buildings, foundations and roadways suffering differential settlement.
• RENFORSLAB® slab lifting Slab lifting solution using expansive polyurethane resin injection at the interface between settled slab and soil. Fills the space and lifts the slab to desired level without demolition, for residential, commercial and industrial customers with sunken floor slabs.
• RENFORJOINT® industrial joint stabilization Industrial slab joint stabilization solution using low-expansion high-density polyurethane resin to fill voids under industrial slabs affected by pianotage (vertical movement at joints caused by handling equipment), for warehouses, manufacturing and logistics operators.
• RENFORVOID® cavity filling Cavity filling solution using expansive polyurethane foam for emergency or permanent filling of superficial cavities and underground cavities accessible to personnel. More cost-effective than traditional concrete filling and avoids creating additional surcharge that could worsen damage, available 24/7 via emergency response.
• TRAITEMENT DE FISSURES PLUS® crack treatment Combined crack treatment and resin injection solution that addresses the interface between foundation footings and bearing soil, filling voids and compressing soil to prevent further settlement and crack aggravation, for buildings showing structural cracking.

It addresses the same foundation settlement problems as Solinjection but with mechanically different, broader portfolio methods.
• Bauer Group: Bauer is a global specialist foundation engineering group offering piling, diaphragm walls, ground improvement, and anchoring. Where commercial or industrial foundation remediation tenders exceed Solinjection's scale, Bauer and its French subsidiary compete directly.

Direct peers

• Uretek: Uretek (and its French subsidiary Uretek France) is the closest direct competitor to Solinjection, offering expansive polyurethane resin injection for soil consolidation, slab lifting, and foundation remediation across France. Both compete for the same insurance claim-driven residential and commercial workloads with overlapping resin-injection technologies.

Emerging players

• Resiplot / SPID Chemical Group: SPID manufactures and applies polyurethane and chemical grouting resins for structural repair, void filling, and waterproofing in France. While primarily a resin manufacturer, it competes with Solinjection on certain void-filling and crack-injection applications for infrastructure clients.
• Webac Chemie GmbH: Webac produces polyurethane and epoxy injection resins for soil stabilization, crack sealing, and structural repair. It is a chemistry-focused emerging player that competes indirectly with Solinjection through applicators and resin supply contracts in France and Europe.
• Minova (Bostik / Arkema-adjacent): Minova supplies chemical rock and soil stabilization products including injection resins used in tunnelling, mining, and civil foundation repair. It overlaps with Solinjection's resin-based ground improvement offering as a supplier and indirect competitor.

Others

• PROVADEMSE INSAVALOR: PROVADEMSE is the INSAVALOR environmental testing platform that validated Solinjection's polyurethane foam H14 non-hazardous certification. While not a commercial peer, it is an ecosystem partner providing the third-party environmental validation that supports Solinjection's insurance approvals.
