SOCOTRAS handle study and maintenance works of road and aeronautical routes. It also do works on special systems and processes in civil engineering, rail, roads, highways and airports.

RAILWAY

• Rail joints on all types of pavements (concrete, paving, asphalt, metal): manual or machine application.
• Platform joints for treatment of floating slabs: manual or machine application.
• Pouring of all types of sealing resins: polyurethane, polymerized/rubberized asphalts, epoxy.
• Core drilling & wedging / saddle anchoring.
• Resin pouring for embeded rail system (rail, crane track …).
• Concrete sawing and milling for rail guide system.
• All types of seals repairs. Wood and concrete sleepers repairs. Tramway platforms repairs.
• Reconstruction of rapid-hardening concrete slabs for rail / road recirculation within a few hours.

ROADS & HIGHWAYS

• Cracks sealing on asphalt pavement.
• Expansion joint sealing.
• Machine-extruded bitumen joint tape on asphalt milled and cut edges.
• Grooving in surface treatment to maximize grip and optimize the rainwater flow.
• Installation of flexible or semi-flexible joints sealant on paved tracks or tram-rails.
• Concrete safety barrier removal by wall sawing or wire sawing.
• Protection of new pavement surface in deactivated concrete.
• Hydro-cleaning and hydro-demolition by water pressure from 400 to 2400 bars.
• Wire guidance system integrated into the covering. Example: Channel service tunnel.
• Micro -planing (diamond-grinding) on ​​concrete or coated surface for rectification or bumps removal.
• Coating technique with resin binders to increase road-ripand reduce the noise levels.
• Epoxy repair of asphalt pavement subject to heavy traffic.
• Coring for asbestos diagnosis or pavement constitution survey.
• Coring for urban furniture laying.

AIRPORT & AIRFIELD

• Reconstruction of slabs in rapid-hardening concrete  for aircraft recirculation to within a few hours.
• Retexturing or surface water removing by grooving to reduce or eliminate dynamic hydroplaning.
• Core drilling for encased runway lights.
• Dowel bar retrofitting or post-anchoring to restore load transfers on cracked slabs.
• Coring, removal of old lighting systems and installation of new lighting system.
• High depth cutting of asphalt or concrete pavements.
• Installation of dowel load transfer systems : to transfer loads across a joint .
• Sawing and widening of concrete seal.
• Joint sealing / waterproofin treatment of concrete pavements.
• Repair of concrete surfaces, joint defects or corner cracks in résine or cement mortar.
• Slab demolition by unbuilding when subject is sensitive to vibrations (decompression, blocks cutting and slab removal in blocks).
• Crack sealing on asphalt pavement.
• Concrete surface impregnation for protection against water and frost.
• Hydrocleaning and degumming of runway.
• Slab undersealing.
• Contraction joint treatment : intended to control the location of slab cracking that develop due to the restraint stresses caused by moisture-related concrete shrinkage, thermal contraction and temperature curling,
• Construction joint treatment : that results from the placement of concrete next to hardened concrete,
• Isolation joint treatment: placed between the concrete pavement and an adjacent pavement or embedded object to allow the concrete pavement to move independently in all directions without damage.
• Trenching and laying of tubes for cable installation
• Grooving and sealing cables on ground

CIVIL & INDUSTRIAL ENGINEERING

• Rapid-hardening concrete.
• Diamond coring, all diameters, all depths.
• Diamond wall sawing.
• Demolition by sawing / coring.
• Diamond wire sawing.
• Drilling and chemical sealing with hydraulic grout or synthetic resin.
• Hydraulic or chemical bursting for selective demolitions.
• Shot blasting before various applications.
• Wire-guiding system or traffic counter wire
• Stabilization of industrial soil by undersealing of synthetic resin.
• Expansion bridge joint.
• Joints and cracks treatments on canals or dams, out of water or in water.
• Repair of industrial floors with hydraulic binders or synthetic resin.

SOCOTRAS, specialist in these professions, has a perfect knowledge and mastery of techniques for the application of bituminous products, polymer products and synthetic resins.

The competence of our men, the performance of our materials and the quality of our products allow us to obtain solid references and to be present in strategic markets.
