Anti-leakage construction process for building block wall

The invention relates to the technical field of house buildings, in particular to an anti-leakage construction process for a building block wall, and provides the following scheme aiming at the problem of poor anti-seepage effect of the block wall in the prior art: the anti-leakage construction process comprises the following steps: S1, manufacturing concrete; S2, evenly smearing the prepared concrete on the inner surface and the outer surface of the wall body, and blocking gaps between bricks; S3, pasting a PVC film on the surface of the concrete on the outer wall when the concrete on the outer surface of the wall body is not dry, and then flattening the PVC film to avoid bubbles between the PVC film and the concrete; and S4, uniformly smearing a layer of concrete on the outer surface of the PVC film, and then pasting a leakage-proof plate on the outer surface of the layer of concrete. According to the anti-leakage construction process for a building block wall, rainwater can be effectively prevented from pe
