    1.- Once prepared the surface, apply the priming MAXPRIMER

    -C. This primer penetrates into the substrate, increasing its strength

    and improving the adherence of the DRIZORO WRAP system.

    4.-Bond the different pieces of carbon fiber sheets using the

    epoxy resin MAXEPOX -CS. The resin is intended to provide

    a matrix, strongly attached to the reinforced element that

    supports the carbon fibers sheets, and also serve as a means

    of transmission of stress f rom concrete to the carbon fibers.

    6.- Finish the application with an over coat-ing layer of

    resin MAXEPOX -CS, verifying there are no air bubbles.

    5.- Use the metallic roller to improve the contact between the carbon

    fiber sheets and the element surface, pressing firmly, eliminating all

    possible air bubbles and wrinkles.

    3.- Prepare the different pieces of the carbon fiber sheets

    according to the reinforcement project.

    2.-Honeycombs and small imperfec-

    tions must be repaired using epoxy

    puttyMAXEPOX -CP.

    Substrate reparationSubstrate Preparation

    Before application of structural strengthening systems, substrate must be

    prepared according to the technical bulletins of each product to ensure

    the right application and the correct adherence to the elements to be

    strengthened.

    strengthening with allow the performance of any type or reinforcement

    due its flexibility and adaptability to the element geometry, suitable to

    reinforce beams under flexural and shear strains or pillars and columns

    under compression by confinement.

    DRIZORO COMPOSITElaminate allows strengthening in beams, girders,

    cantilevers, joists, and other structural elements under tensile stresses

    due flexion, reducing the deflection of the in service element and

    improving the cracking state.

    DRIZORO CARBORODrods, behave as steel rebars, fulfilling the same

    laws, requiring smaller diameters to assume the same loads, lightening

    the structure and without corrosion problems.

    Concrete, steel and wood elements under tensile strain:beams, joists, slabs, girders, cantilevers, etc.
