Industrial & energy-producing structures
As a specialist of structural systems and ground engineering, we provide bespoke solutions combining design and methods, in-house systems and project execution for the construction of industrial and energy-producing structures worldwide.
We deliver bespoke inspections, preservation plans and maintenance operations to manage the ageing of structures and optimize their safety, durability and asset value.
As specialists of structural components, we specialise in the repair or replacement of parts of an asset that are essential to guarantee continued safe use. The repair or replacement of parts of an asset due to structural deterioration is essential to maintain or reinstate it in a condition that guarantees continued safe use. As specialists of structural components, VSL helps owners and asset managers to define a tailored-made solution balancing cost, safety, continuity of service, performance and durability.
We offer structural modification solutions to accommodate new uses or requirements that help maintain a structure’s value, comply with the latest design codes and safety recommendations or answer to new needs.
Various factors can trigger the need to strengthen a structure in order to achieve compliance with structural design requirements:
its deterioration over time,
an increase in loading,
a change of design codes, or
a deficit in an element that had not been properly designed or executed at the construction stage.
How VSL can help you
VSL can propose a full package including the comparison and selection of suitable solutions, design and detailing, supply and installation of strengthening systems and the undertaking of all associated site works.
Your collaboration with VSL starts with an assessment of the strengthening needs. Thanks to our technical expertise and operational knowledge, VSL can engineer the best solution making use of a wide portfolio of active or passive strengthening systems:
We carry out critical strengthening works ourselves, guaranteeing the highest safety and quality standards while increasing efficiency by eliminating interfaces between multiple parties.
Our experienced engineering teams adapt each strengthening measure to the local requirements and develop creative methods to facilitate safe interventions even when works have to be done under live traffic or where operation of the asset cannot be halted.
VSLoop®: a brand-new post-tensioning design to upgrade your structure
VSLoop® has been developed from a unique design to deliver optimum strengthening as well as increased robustness, efficiency and simplicity in the preparation and installation processes. The VSLoop® anchorage system utilizes a concept of loop strands to anchor an external tendon and strengthen existing structures.
What are the VSL structural strengthening solutions?
VSL delivers a variety of solutions to meet the project’s needs, including:
strengthening to counter deformation
shear reinforcement
strengthening against punching shear
increasing foundation capacity
seismic strengthening
stability enhancements
To do so we supply and install a wide range of strengthening systems, such as:
Additional post-tensioned tendons
Use of fiber-reinforced polymers (FRP) for strengthening and jacketing
Addition of steel plates or other composite solutions
Enlargement of structural sections
Strengthening of foundations using jet grouting, ground anchors or soil nails
Modifications to structural systems to create or restrain degrees of freedom
