Structural Repairs & Reinforcements


Apoltec specializes in foundation consolidation, epoxy injection and anchor bolt repair and replacement

Foundation Consolidation

Addressing disbanding construction joints or stress cracks in machinery foundations, Apoltec offers solutions involving epoxy-polymers injected with high tensile steel rebars for reinforcement. 

Our modified epoxy-polymer adhesives provide excellent bonding to various materials, including concrete, ensuring structural integrity and resistance to thermal and mechanical shock.

Foundation Consolidation

We develop and test products for specific use cases. In this case, a resin with high compression, tensile, and flexural properties that cures underwater.

Foundation and skid Injection and consolidation

  • Epoxy injection: Our injection system, utilizing Apoltec 300/370 modified epoxy-polymer adhesive, fills voids and gaps between steel skids and concrete, creating a seamless foundation.
  • Embadment Reafirmation: Localized high pressure epoxy adhesive oil compatible injection that expel unfiltered oil and bond back anchoring mortar and rod with concrete
  • Skid Mounted Machinery: Increasing damping mass by filling with cementitious materials and injecting epoxy resins to help alleviate vibrational energy in the vibrating structure

Mass Enrichment 

Whether facing stability issues due to structural design flaws or degradation from corrosion, Apoltec offers expertise in fiber application and epoxy reinforcements.

Technical Information

Any structure submitted to an aggressive environment (marine, petrochemical, several industrial processes) is exposed to constantly physical and chemical attacks, drawing to material pathologies. This alters its mechanical and functional features leading to poor performance, even putting it out of order and risking safety operation.

For a proper maintenance, APOLTEC systematically studies the current dysfunctions and regularly carries out analysis, test, and its evaluation in order to determine the pathology progression and severity damage.

Reinforced concrete structures. 

Main causes of pathologies: atmospheric gases, salty, acid and selenium waters, organic products and fire

Pathologies: disintegration, ettringit formation, carbonatation, rebar corrosion,…

Main symptoms: cracks, swelling, spilling, colour changes, efflorescence,…

Steel structures.

Chemical, physical, mechanical, even, biological influences trigger out pathological processes derived from material composition and/or the construction design applied.

As main damages we could find laminar tearing, excessive deformations, fatigue, wearing and mainly corrosion and oxidation processes.

Technical solutions.

To disguise the symptoms is not the proper way to confront the problem. It´s requested a thoroughly survey which lead us to discover the core to stop the damage progression, to protect materials, to reinforce where needed for releasing critical stresses and, finally, recoup forms with the best suitable materials.

The anchoring system is essential to constrain / restrain the inertias and moments.

The anchoring system is conceived to apply evenly distributed compression strength to counteract the balanced and unbalanced forces; and also to provide compression strength to the surrounded materials (grout and top part of the concrete foundation) due to its shortage of tensile and shear resistance.

The anchoring system is designed to resist fatigue under normal stresses (given by compression-traction cycles). When it is submitted by tangential ones (flexural and shear forces; torsion and flexural moments) for which they are not design, bolts’ failure are achieved sooner or later.

And that happens when the anchor bolts start loosening the tension (lessen torque requests’) due to many reasons, but mainly oil penetration, corrosion, grout contact surface degradation, cracks, and so on.

To improve the anchoring system, request certain performances:

  • Repair the anchoring system by coring out the existing damaged bolt and embedding a straight new one.
  • Replacing by new bolts or connecting the upper new one by a threaded sleeve to the existing one.
  • Check the tightness and re-tight at the specified torque according to the bolt material, the manufacturer requests’ and the grout compression strength by controlling the elongation (for the stretching length) of the bolt and the real bearing area of grout

With over 25 years of experience, Apoltec specializes in high-pressure epoxy injections to consolidate foundations.

Our resin displaces corrosive products, restoring stability and integrity to foundations.

Consistency loss can result from factors like corrosive infiltration, vibrations, and internal corrosion.

Apoltec addresses these issues with precision injection and repair techniques, ensuring rapid and effective foundation restoration.

With over 25 years of experience in anchor bolt repair and foundation stability restoration, Apoltec ensures client satisfaction and reliable solutions.

Our expertise, materials, and dedicated team make us the preferred choice for structural repairs and reinforcements.
