Some friends wrote letters to us, which reflected that there was leakage in their top houses after long time of sun and rain. How to deal with this situation? In fact, the general residential building, especially the top floor, the cement of which will inevitably have crack after long time of sun and rain. Once it has cracks, it is easy to expose the internal steel structure in the air, causing corrosion. After a long time, there will be more than leaking. It also will have security risks. In this situation, whether it is useful to use carbon fiber cloth to reinforce or not. Please listen to our analysis.
The cracks are in the floor position. We should follow the principle that is firstly to treat the cracks, and then strengthen the floor. So the general construction process is firstly to pour into the sealants and fillers, then use carbon fiber cloth to reinforce. Construction methods are as follows:
a. Firstly, we should check whether there is exposed steel bar in the crack. If there is exposed steel bar, whether there is corrosion, then clean up the exposed part, using leveling repair adhesive to repair and recover;
b. We polish the parts that will be pasted by the carbon fiber cloth and remove the surface dust and oil until the new concrete surface exposes. Then we wipe the concrete surface with acetone again to keep the concrete surface clean;
c. We apply the bottom glue, and then level the uneven position with leveling adhesive;
d. When we confirm the leveling adhesive is dry, we can paste the carbon fiber cloth;
e. We should ensure that there is no air between carbon fiber cloth and carbon fiber glue as far as possible. We can use roller to roll many times along the direction of carbon fiber cloth to let the carbon fiber glue immerse in the carbon fiber;
f. After pasting the carbon fiber cloth, they need natural conservation for 24 hours to achieve the initial curing. We should ensure that the process of curing has no interference.
(The carbon fiber cloth reinforcement of the floor)
This is the basic construction process of the carbon fiber cloth reinforcement of the floor. If there is a similar situation in the toilet or the top floor of your house, you should deal with it immediately. Because once the cracks penetrate, there will be very serious security risks. It is very important to use carbon fiber cloth to repair the cracks timely.
