It is important! The specification is a general specification.
It is necessary to consult with the Technical Department of BI. J. Technologies, before performing the work.
Be sure to follow the relevant standards.

Preparation of infrastructure
1. The quarrying should be performed in areas where defects and cracks are visible, indicating the beginning of corrosion in the iron.
2. Remove damaged plaster, remove crumbling, cracked concrete, concrete whose face has been hit by salt concentrations or inflorescences, and concrete with gravel canisters until a stable concrete surface is obtained.
3. In the place where there are deep and deep cracks in the concrete extend the crack to the width 2 cm and depth 3 cm.
4. Quarries are performed around the reinforcement rods damaged by corrosion at least 10 cm wide, and 10 cm on each side beyond the area where the corrosion is visible.
5. The quarrying will be carried out with a mechanical hammer. In sensitive areas, it will be done with hammer and chisel, in accordance with the instructions of the engineer at the site.
6. If the prosthetic rods are damaged, cut the damaged rods, replacing them with new rods with the existing diameter. Cutting the rods will be done with a suitable mechanical saw, and the new rods will be welded to the existing and anchored in concrete with suitable anchors. In any case, the 0.5 cm rods shall be removed from at least the cut concrete and the thickness of the cover shall be at least 2.5 cm unless otherwise approved by the Engineer.
7. After the quarrying works, the zinc bars and steel profiles that were exposed from scaly and loose rust are cleaned. Thin, close rust can remain. You can use a steel brush or electrical equipment.
8. Spread an anti-corrosive protective layer. J. Armusil 340 on the two-tier reinforcement rods.
Performing the rehabilitation work
1. Brush primer on base Me. J. Bond 17 For the bonding of new concrete to the old, on the reinforcement rods, steel profiles and all the concrete that require repair with a hard brush.
2. Applied Me. J. Concrete rock 330 Above the primer and fasten the mixture to the reinforcement iron and the concrete substrate at least 8 mm thickness and up to 50 mm. Note that no air bubbles have been formed around the fucking iron.
3. When it is necessary to build a thick layer, wait two hours between layer and layer. In order to allow good adhesion between the layers, the concrete surface should be kept rough.
4. Sliding the face of the restoration with Malage for a perfect finish detail.
5. Application of sealing coating with the help of Me. J. Flexil 162
6. Promise good curing for at least 3 days.
7. can be used Bubby. J. 305 refractory Instead of my heart. J. 330 rock concrete in reconstruction of concrete.
All of the above is only a recommendation, given according to the best knowledge we possess and our extensive experience.
However, because the work is not under our control, the factory's warranty is limited to the quality and quality of the product only.
The operation must check compliance with its needs and proper performance of the work.
