    In construction projects, leakage occurs in buildings that are under construction or have completed construction due to factors such as inadequate design, poor material selection, improper handling of construction and substandard construction quality. If not timely governance, then whether it is construction progress, construction function, project quality or structural safety, will be affected. Different causes will lead to leakage of different parts, and for each leakage of the site has the corresponding measures to solve the problem
    the
    .
    leakage of the roof panel
    causes:
    (1) reinforced concrete slab quality is not up to standard, there is micro-hole penetration phenomenon;
    (2) the maintenance measures taken are unreasonable or the maintenance time is too short,
    (3) waterproof coating is not extended well, resulting in it being cracked with the cracking of the plate surface,
    (4) is not in accordance with the secondary vibration, secondary surface process requirements, etc. for construction,
    (5) roof panel cracking.
    we plug the leak?
    the damaged waterproof surface is partially removed to ensure that its surface is free of debris and dust. Again in the waterproof layer surface brush with the same waterproof coating as before, or the damaged waterproof layer surface completely removed, has made it exposed roof structure, through the plate and wall water leakage measures, closed the cracks, and in a certain area of the paint waterproof coating and paste fiber paper cloth enhancement.
    deformation seam leakage
    causes:
    (1) seam material cracking, or deformation seam filled sealing material water tightness is poor;
    (2) deformed seam structure does not meet the relevant specifications;
    (3) waterproof coating and seam material at the root of the retaining wall fall off;
    (4) cover plate construction error, resulting in it can not meet the normal work of deformation seam, so that the cover plate pulls apart, leakage occurs,
    (5) waterproof coating and seam material aging.
    we plug the leak?
    After lifting the cover, fill the elastic seam material in the seam and install the cover plate correctly, remove the damaged waterproof coating and insulation layer at the root of the retaining wall and remove the original seam material, scrape the seam material after cleaning up the seepage, and strengthen the layer at the surface.
    In addition, no other debris should be built inside the deformed seam, so that the seam should be kept clean and through, the production of the cover should meet the structural requirements of the deformation seam work, to ensure that its subsidion, contraction is normal, when installing the cover plate to be neat, flat, solid installation.
    Basement sidewall leakage
    causes:
    (1) part of the wall screw water flat welding quality does not meet the requirements;
    (2) construction quality is not up to standard, part of the concrete joint secondary vibration is not dense,
    due to the waterproof coating is not adhesive or has been damaged.
    we plug the leak?
    First of all, the water seepage should be cleaned up and cement-based (cement-based cement as a gel material, the production and manufacture of a series of building materials, such as mortar, concrete, grout materials, and their products). Waterproof coating for leak-blocking treatment, clean up, through the use of water-milk neoprene asphalt waterproof coating and other fiber-reinforced materials have been treated for water seepage.
    leakage not only affects the progress of the construction project under construction, but also affects the performance of the completed project. On the other hand, leakage will affect the safety performance and durability of buildings, if we do not pay attention to, it will affect the quality of buildings, so for leakage problems, we can not be underestimated.
