5 Sai Lầm CHÍ MẠNG Khi Xây Tường Nhà Phố

In the construction of townhouses, many people think that building a wall is just about laying bricks - plastering, but in fact, this is the item that determines the flatness - durability - waterproofing ability - airtightness, and the ease of interior installation later. Just overlapping joints, tilting a few millimeters, the wrong size of the door frame, insufficient steel beard... are consequences that can drag down the entire finishing part: cracked walls, reverse seepage, doors that cannot be installed, open-mouthed cabinets, and even having to chisel and rebuild. So what should be noted when building a wall according to technical standards? In this video, GreenHN engineers will share in detail each step of direct inspection at Nguyen Khang construction site: How to check the size of the door frame, always leave 2-3 cm on each side for the plaster layer so that the door installation does not lack size. Why is it necessary to stretch the string when building a wall, use a vertical ruler - horizontal ruler to control the squareness and straightness of the wall. Principle of not building joints, mortar joint thickness from 8-20 mm and reasons why joints should not be too thick. How to choose mortar grade 75-100, suitable sand type and how to read the mix ratio table right on the cement bag. When should solid bricks be prioritized (especially for surrounding walls, toilet walls, waterproof exterior walls) to increase bearing capacity - sound insulation - better waterproofing than hollow bricks. The role of steel beards anchoring walls to columns, placement density - drilling depth, and how to make corner locks - brick holes so that the new wall is firmly connected to the old wall. How to use a 2-3 m aluminum ruler to check flatness, slope; how much error is acceptable, when to repair or demolish and redo immediately. Reasons for subtracting drainage holes to build scaffolding, plaster the outside and handle waterproofing properly. 💚 Building a wall is not just about “stacking bricks high enough” – it is a technical task that directly affects the quality of the finished product and the user experience later. Doing it right from the beginning will save a lot of repair costs later. 👉 If you are preparing to build a house, or are an architect – engineer – contractor who wants to find more practical perspectives, please subscribe to the channel and leave your questions in the comments section.
