The purpose of the process is to dislodge any weak or corroded elements of the structure and to properly prepare the surface for further renovation, i.e. reprofiling the structure, applying waterproof coating, or strengthening the structure with shotcrete and reinforcement. Depending on the type of cleaned surface, its designated use, and place where the work is performed, different types of cleaning processes are used with different pressures. Unpainted concrete and brick structures without bituminous coatings are cleaned only with water at pressures ranging from 400 to 2000 bars (5,800 to 29,000 PSI). If the structure was earlier protected with waterproofing coating mentioned above it may be required to use wet sandblasting at a pressure of up to 1000 bars (14,500 PSI). Painted and unpainted steel structures are sandblasted. BLEJKAN uses Putzmeister equipment: Dynajet 500, Dynajet 800th and Dynajet 170 UHP.[\/vc_column_text][vc_empty_space empty_h=”2″][vc_gallery el_id=”gallery-18075502″ type=”carousel” medias=”72867,72868,72869,72870,72871,72872,72874,72873″ carousel_lg=”3″ carousel_md=”3″ carousel_sm=”1″ thumb_size=”three-two” gutter_size=”2″ carousel_interval=”3000″ carousel_navspeed=”400″ carousel_loop=”yes” carousel_dots=”yes” stage_padding=”0″ single_overlay_opacity=”50″ single_padding=”2″][\/vc_tab][vc_tab title=”SPOT REPROFILING OF STRUCTURES AND RUSTPROOFING OF UNCOVERED REINFORCEMENT” tab_id=”1531206013558-4-8″][vc_custom_heading text_size=”h3″ text_weight=”300″ text_transform=”uppercase” text_color=”accent”]SPOT REPROFILING OF STRUCTURES AND RUSTPROOFING OF UNCOVERED REINFORCEMENT[\/vc_custom_heading][vc_empty_space empty_h=”2″][vc_column_text]This type of work is required when the damage to the structure is beyond merely surface corrosion or leakage. Repairs of this type apply to these parts of the structure which suffered damage caused by an impact, poorly performed vibration of reinforced concrete and later detachment of a fragment. Quite frequently one can notice that large slabs of the structure come off at the point where they touch the reinforcement. As a result the structure loses a layer of cover which causes the deterioration of reinforcement and later necessity to repair or replace it.

The type of material depends on the type of damage to the structure. The pressure of injecting the material ranges from 100 to 250 bars (1450-3625 PSI). The key purpose of the injection is to seal wet or dry gaps and cracks, bind a cracked structure, fill and seal expansion joints with flexible material, stabilize soil, create a structure\u2019s vertical and horizontal insulation. In the case of small cracks high-pressure injection is an excellent repair measure if the crack is under 0.5 mm.

The coatings can be reinforced or without reinforcement, depending on the type of structure and its purpose. Layer thickness ranges from 40 to 100 mm. The application takes at least two stages \u2013 spraying up to the reinforcement, and over the reinforcement. The advantage of this type of strengthening is that it is easy to apply in hard to reach places and on irregular shapes.
