As the real estate and construction industry continues to evolve, the quality of house construction and the awareness of housing safety are gaining increasing attention from the public. However, large-scale construction quality accidents are still heard of occasionally, causing quite a chill. Below, we recommend several simple and practical methods for identifying house quality issues in Henan. Let's learn with the editor!
1. Check the wall
Several Methods to Identify the Quality of External Wall Construction
If the exterior wall is clad with facing tiles, observe primarily for any signs of detachment or unevenness, check if the joints are level and vertical, and ensure the color and texture of the tiles are harmonious.
b. If the exterior wall is coated with cement mortar and then waterproofing paint, observe for any signs of cement mortar peeling or cracking. Currently, plain brick walls are more commonly used in low-rise villas, conveying a sense of classical and solemnity. Pay attention to whether the joints of the plain brick wall are filled adequately and if the bricks are tightly packed.
    c. If penetrating cracks are found on the exterior wall, it indicates that there are issues in the design or construction stages of the house. It is advisable to have the house quality assessment department conduct a re-evaluation.

It is advisable to avoid using veneer tiles or mosaics for exterior wall decoration, as the horizontal gaps in the tiles can easily accumulate water, leading to wall leaks. For interior walls, in addition to checking for cracks, observe the wall's convexity or concavity. There should be no large areas of hollowing or cracking. Moreover, whether the horizontal and vertical wall lines form a straight line is a significant indicator of the wall's quality.

2. Viewing the building floor
The ground level encompasses two meanings: one is the ground floor and the other is the floor slab. For the floor slab, it is first determined whether it is a precast slab or a cast-in-place slab. The floor slabs in low-rise and multi-story buildings are primarily precast components. One should inspect whether the floor slabs are flat and if there are any cracks.
The causes of the cracks are twofold:
The circular beams of the house are uneven, and the adhesive paste is not evenly distributed during the boarding process.
② The issue is that the prefabricated panels did not meet quality standards, with excessive bending.
Mid-to-high-level and high-level building floor slabs should primarily be inspected for any exposed steel or honeycomb surface phenomena. The concrete strength grade cannot be visually determined; quality inspection reports can be consulted. If the concrete quality is poor, it can be easily pried away with hands, especially at locations like the corners of columns.
    The flooring for kitchens and bathrooms must be a cast-in-place solid slab; precast panels are not permitted. This is due to their specific waterproofing requirements.
For the flooring in kitchens and bathrooms, a water-tightness test can be conducted: fill with water to a depth of 20 to 30 millimeters and maintain for 24 hours. If there is no leakage, the flooring is deemed to be qualified. Additionally, check if the slope of the flooring directs towards the drain, and ensure there are no reverse slopes or water accumulation on the floor.
The ground level indoors is typically 45 cm, or three steps, higher than the outdoor ground level. In some cases, it can be as high as 60 to 90 cm. It is essential to carefully inspect the moisture-proof design and measures. It is recommended to hire a professional home inspector to check the floor thickness to prevent builders from cutting corners and compromising quality.
3. Roof Inspections
Most residential roofs are either flat or sloped. The primary functions of a roof are to prevent water leakage, insulate, and provide heat insulation.
For top-floor residents, the roof is a crucial quality indicator. First, check if the roof's drainage slope, outlets, and eaves gutters are properly designed. Inspect the stability of the downspouts and for any leaks.
Roof leaks often occur at areas of structural changes, such as the junction between roof panels and walls, expansion joints, and settlement joints. Roof waterproofing has always been a major concern for designers, construction companies, and users. While many new types of roof waterproofing materials are emerging, the quality of roof waterproofing largely depends on the quality of the construction work.
