Why concrete and cement pavement need a waterproof base pavement shot blasting machine

As we all know, concrete and cement pavement projects are most afraid of water leakage, because water seepage will cause concrete to loosen, fall off, and steel bars to corrode, which will cause certain hidden dangers to safety and quality.


 


One of the reasons for water seepage is that the treatment of the concrete surface layer cannot completely remove the residual substances on the surface, and does not retain a certain rough surface to ensure the bonding strength of the waterproof layer and the structural layer.


 


The shot blasting process of the road shot blasting machine for the waterproof base layer can clean the laitance and impurities on the concrete surface at one time, and at the same time roughen the concrete surface to make the surface rough and uniform, which greatly improves the bonding strength of the waterproof layer and the concrete base layer. . And in this process, defects such as cracks in the concrete can be fully exposed, so that remedial measures can be taken in advance. Therefore, under certain conditions, the use of shot blasting to treat the base surface can better ensure the waterproof effect.


The details that need to be paid attention to in the construction of the shot blasting machine for the waterproof base are as follows:


1) The places with serious unevenness of the structural board should be polished or a thick polymer mortar should be used, and the strength of the mortar should meet the requirements; 2) Areas that cannot be cleaned by the shot blasting machine such as drain holes, pipe openings, and yin and yang corners should be used. The angle grinder is cleaned, polished and smoothed, and care should be taken not to produce grinding grooves.



If a large area is constructed, the shot blasting efficiency is very high. On the construction base handed over by the general contractor, concrete residues, lumps, oil stains, pollution, etc. are cleaned manually, which is very labor-intensive and difficult to clean, and the road shot blasting is used. The machine can quickly solve these problems, the construction efficiency is very high, and the labor cost is effectively saved.
