Structural Strengthening/Repair of structures is a field of engineering which is gaining momentum and has seen huge demand in recent days. The requirement of highly skilled professionals for this type of work makes it challenging as very limited companies exist in the region, making it a highly-priced scope of work for those companies.
The requirements in this discipline have increased in order to overcome the shortcomings in design and completed structure, to meet the requirements of clients seeking modification after construction, to restore the structural capacity after prolonged usage or diminishing strength capacity over a period of time, the effect of extreme conditions which the structure may be subjected in unpredictable situations such as earthquakes, fire, storm, etc.
Hence a total solution from complete site investigation and assessment, most suitable structural strengthening solution, and application /execution on-site can be had under one roof.
Most importantly, the strengthening procedures can be carried out on old structures, under construction structures, as well as recently completed structures.
ESF, a highly competent Post Tensioning company having worked in various types of structures has come together with HCR, to provide economical and structurally safe solutions for its clients. ESF with its strong technical skills and HCR with its vast structural strengthening/repair expertise can now offer total structural strengthening/repair solutions for all types of structures.
Joint and Expansion Joint Repairs
Enlargement/Jacketing of Beams, Columns, and Slab
Carbon Fiber Reinforced Polymer (CFRP) Wrapping
Carbon Fiber Reinforced Polymer (CFRP) Strips/ Laminates
Crack/Kicker Joint Leakage
Pipe Head Leakage
Pipe Sleeve Leakage
The Cracks in concrete structures usually signify more major problems and must not be ignored.
Cracks can cause subsoil water to leak into a faulty structure or storage water to leak out Furthermore, cracks can expose reinforcing steel to oxygen and moisture, hence making the steel susceptible to corrosion With ESF, these problems are tackled through the most sophisticated systems of injection using state of the art machines to completely fill the crack either with epoxy or polyurethane resins.
Shotcrete is, in effect, a version of a cast-in-place concrete wall Rather than placing concrete into forms, however, a fresh mix is sprayed onto wall panels that have been erected in the shape of the building. It applies concrete from a pressurized hose to encompass the reinforcement and build up the wall thickness. Forming structural shapes that include walls, floors, roofs, and other assemblies. It is also called gunite because a nozzle or "gun" is used to shoot material at the form face.
Foundation settling and shifting can be caused by building a structure of expanding or contracting soil, improperly compacted fill soils, or from poor or erroneous maintenance of the earth around the foundation Regardless of the cause of a settling foundation, this settlement can ruin a building's value and even render it unsafe or unlivable.
We are associated with the best structural strengthening technology providers to offer our clients the most advanced solutions for those applications which are due to accidental overloading of structures, design modifications, and faulty construction Based on structural analysis and calculation by third party application of a proper system to provide the required structural durability such as Carbon Fiber is undertaken.
Prevention is better than cure. A protective coating on a concrete structure will greatly enhance its durability and resistance to degradation from adverse conditions, hence increasing the lifespan significantly This is especially true in the salt-laden atmosphere of the Middle East.
Structural refurbishment is considered a vital ingredient to successful project completion and the longevity of the structure.
Proper installation of load-bearing units, underground pipes and various fixings require voids formed between the equipment and soil, or between load-bearing units, to be thoroughly sealed, ensuring structural stability.
Grouting is the injection of specially formulated cement, epoxy, or other mixes into the ground to improve its strength or reduce permeability It is carried out by drilling holes into the foundation to intercept open cracks, joints, fissures, or cavities, then pumping the grouting compound under pressure, hence sealing any voids.
Proper testing and investigation should be undertaken in order to ensure the longevity of the refurbishment structure.
Diagnosis will be followed by remedial measures for each and also the budget costing.
The findings will be intimated to our client during the investigation and the remedial measures discussed A range of solutions will be proposed based on the conditional of the structure and budget available.
We will assist with appropriate advice and a structured testing methodology based on the urgency of the issue.
