We provide conclusive recommendations on the best option available based on our engineering and construction knowledge, enabling our clients to make an informed decision when weighing up the costs of a physical upgrade against the level of protection provided.

Concrete Repair and Restoration

Concrete repair and restoration specially in critical infrastructures is as important as any other maintenance activity and must be carried out in a timely manner. Repairs performed at early stage would save extremely expensive remediation that may be required at latter stage. 

From small concrete repair projects to multi-faceted full-scale restoration projects in Nigeria, JuNeng Nig.Ltd can deliver on every phase including:  Assisting owners and engineers in problem identification; Development of concrete repair options and feasibility studies; Budget pricing of repair options and delivery options to meet your facility’s needs; Turnkey delivery and management of the complete repair process and Design-Build Contracts Maintenance Contracts.

Our Concrete repair and restoration services include: Crack repair; Repair of concrete honeycombing, delamination and spalling; Repairs to corroded embedded metals; Concrete fireproofing repairs; Expansion joint treatment; and Restoration of historic structures.

Structural Strengthening

Structural strengthening, restoring and adding capacity, is an integral part of today’s structural rehabilitation industry. Structural strengthening may be required for increasing load capacity of beams, columns, walls, and/or slabs, seismic retrofitting, supporting additional live or dead loads not included in original design, to relieve stresses generated by design or construction errors, or to restore original load capacity to damaged structural elements. 

As an expert infrastructure protection company, JuNeng NigLtd is a recognized leader in the research and development of the structural strengthening technology in Nigeria. Along with the more conventional strengthening approach, where additional reinforcing steel is added to the structural element by increasing its concrete cross section, JuNeng NigLtd is an expert for selecting and installing the right strengthening system for the job.

Our structural strengthening systems include: Advanced Fibre Reinforced Polymer Composite Materials, Structural Steel Bonding and External Post Tensioning.

Advanced FRP Composite Solutions

Advanced FRP composite solutions is new type of structural rehabilitation system that employs the application of high performance fibres of carbon, E-glass and Aramid reinforced polymeric composites, for repair and strengthening of concrete structural members.

Backed by our in-house expertise in composite engineering and the unique features of advance composite materials, JuNeng NigLtd uses fibre reinforced polymer (FRP) composite systems to strengthen a wide variety of structures for flexure, shear, axial loads, and structural upgrading. Both Glass FRP (GFRP) and Carbon FRP (CFRP) are used in these applications with CFRP being used for most structural applications. CFRP materials are used as they exhibit low creep, and compared with steel, are thinner, lighter, and have 10 times the tensile strength.

Our CFRP Structural Rehabilitation solutions include Glass/Carbon Fibre Wrapping Services, Carbon Fibre Laminates with Post-Tensioning, CFRP Composite Retrofitting, External Pre-Stressing by C-Fibre Laminates, Carbon Laminates Structural Strengthening, and CFRP plates/rods/tapes/rebar.

Structural Protective Lining

JuNeng Nig.Ltd has years of experience in the application of a wide variety of protective coatings for concrete including epoxy, polyurethane, polyester, polyurea, calcium sulfonate, and other unique systems to protect concrete from chemical attack. Selecting the proper protective coating for the situation is paramount in any successful coating application.

JuNeng NigLtd uses its experience with a variety of chemicals and conditions in selecting the appropriate protection system. The selection of protective coating systems ranges from water-borne, solvent-borne and solvent-less coatings for floors, walls, structural steel, and a variety of special needs. JuNeng has access to very specialized concrete coating systems that have unique properties, such as; elastomeric and highly chemical resistant, thermoplastics, extreme abrasion resistance.

JuNeng NigLtd is also intensely involved in the following structural protection services: corrosion mitigation and protection, industrial flooring, concrete sealing, waterproofing and lining.
