Whether there are obvious gaps and uneven ground level, the test ground level is to measure the horizontal error between the floor and the ground in the doorway farthest from the gate. The method of measurement If you do not bother, then the method is quite simple. Go to the hardware store and buy a small transparent water pipe, about 20 meters in length, then fill it with water. First draw a sign 0.5 meters or 1 meter off the ground at the door. Then adjust the level of the water pipe to the height of this sign and find someone to fix it in this position. Then move the other end of the hose to the room furthest from the door. Then look at the height of the water pipe at the place, and then make another sign. Then use a ruler to measure how high this mark is off the ground. The difference in these two levels is the difference in the level of the house. You can also use this method to analogically measure the level difference in the entire house. In general, if the difference is about 2 cm, 3 cm is acceptable. If you go out of this range, you have to pay attention. Is the ground level? Splash a layer of water on the ground so that the water does not converge towards any one party. Wall, ceiling, floor With or without tilt, bending Whether there is a bulge or depression; a flashlight shines Is the wall level? Is there a flower on the wall? Whether the bearing walls, beams, and columns meet the design specifications, if the cracks in the bearing wall penetrate the entire wall and pass through the back, it indicates that the house has hidden dangers and whether the steel bars are exposed. Tap with a wooden stick to see if there is no sound Whether the wall has obvious color difference Whether the yin and yang angles are straight; use triangle ruler Whether the wall and the floor have kicks Whether the kicking is too little can protect the wall from contamination Whether the skirting board is smooth Whether there are cracks or brush marks, if the crack is at an angle of 45 degrees to the corner of the wall or perpendicular to the beam, the settlement of the house is serious and there are structural quality problems. There are no water stains, cracks Whether there is a small crack in the ceiling Note that there is no air conditioning hole in the relevant location Check whether there is lime “explosive electricity†on the wall. This is because lime has not matured enough or there is too much sediment or uneven mixing in the cement. It can be used to knock “blast points†with iron, if a large area is found. The looseness and detachment are also quality issues, which will cause great troubles for the buyers' residence and decoration and cannot be ignored.
