Some of our projects

Technical Information

Water losses are generated mainly due to cracks in the pit walls or floor, these deformations are usually caused by material stress.

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.

technical solutions tailored to the specific pathology progression and severity damage.

Apoltec relies on its Apoltec 340 Epoxy Injection, specially formulated for moisture resistance and exceptional bond with wet or submerged concrete, to effectively seal leaks.

Additionally, the Apoltec 840 Grouting range is deployed for conditions of permanent humidity, ensuring high fluidity and minimal retraction.
