We perform waterproofing at concrete structures to provide watertightness, as well as structural recovery where there were pathological manifestations in elements of the structure, such as:

  • Sandboxes;
  • Floc Tanks;
  • Decantation Tanks;
  • Filter;
  • Distribution Channels;
  • Reservoirs;
  • Pipelines;
  • UASB reactors.

Technologies applied:

  • Waterproofing with PVC geomembrane;
  • Infiltration treatment in fissures, expansion and concreting joints using flexible injections with Polyurethane Resin (foam and gel) / Polymeric Acrylic Gel / Structural Polyurethane;
  • Structural treatment in cracking and fissures without infiltrations using chemical injections with Structural Polyurethane, Microcement and Epoxy Resins (to recover structure´s monolithicity);
  • Polymeric Acrylic Gel Injection in the soil to obtain watertightness;
  • Waterproofing using mortar projections or polymeric membranes;
  • Structural recovery using Carbon Fiber;
  • Waterproofing and chemical protection of the structure by application of Xypex Crystallizing System;
  • Deep concrete treatment (disintegrated concrete / exposed and/or oxidized armatures) using projection of Polymeric Mortars;
  • Superficial concrete treatment (apparent concrete).
