I have a semi-basement in my house, I want to use it, but it is very hot. I would like to ask the experts, I am currently renovating. What should I do for this semi-basement?

Waterproof engineering is the key
Yuan Zhiren, chief engineer of Yuanzhou Decoration Group, said that the structural characteristics of underground and semi-underground spaces determine that this part of the space will penetrate into the wall of the building due to the large moisture in the soil, resulting in a basement and a semi-basement wall. Surface, top surface moisture, mildew and other issues. Therefore, no matter how to design the function of this part of the space, the first thing to do is to add a layer of internal waterproofing to the ground and interior walls of the basement under the conditions of the original developer's delivery.
First of all, it is necessary to choose a suitable waterproof material. It is best to use a permeable crystalline waterproof material, which is more suitable for plugging underground space. The corners, walls and ground joints must be painted in place. Because it is impossible to do the water shut-off test, the workers need to work especially carefully. Secondly, for owners who have stricter requirements for waterproofing engineering, it is possible to increase the safety of the waterproof engineering by adding a part of the flexible waterproof material construction. For example, a wall surface with a height of 5 cm above the ground and a portion with a riser can be coated with a layer of flexible waterproof material within 10 cm of the height of the wall, and a layer of flexible waterproof material is added to the crystalline waterproof material. Waterproof membrane for enhanced water resistance. This can avoid the leakage problem of the waterproof material in the joint between the wall and the ground, especially the waterproof gap caused by the construction of the floor drain and the riser.
In terms of top decorative materials, it is recommended to choose a light steel keel ceiling with galvanized layer or anti-corrosive paint, waterproof gypsum board; for floor decoration, it is recommended to install anti-corrosion wood on the wooden keel after waterproof treatment, not only moisture-proof, resistant Corruption can also achieve the decorative effect of returning to the original.
Lighting and ventilation planning
According to Mr. Zhiren, many of the basements have no windows, or the windows are small, and the conditions for natural lighting or window ventilation are very poor. Manual ventilation measures must be taken to ensure the daily use of the owners.
Year Zhiren suggested that the owners should carefully plan the improvement measures for lighting and ventilation in the semi-basement and basement. For example, an ordinary floor plan with underground and semi-underground space can choose to install an air conditioner with dehumidification function. If you plan to set up a gym in the basement or semi-basement, you should place your fitness equipment close to the window, otherwise it will be easy to feel uncomfortable during exercise.
Semi-basements and basements generally require supplemental light sources during the day. Experts suggest that owners with affordable economic conditions can also consider new types of equipment, such as solar energy collectors that reflect sunlight, and supplement the basement with natural light sources by reflection of light in the prisms.
â– Tips
Three factors affecting space utilization
If you consider buying a space with underground or semi-basement, experts also recommend focusing on the original structure, ventilation and other aspects of the selection, as much as possible to understand.
First, the original structure of the underground space or semi-basement space. If the basement originally has walls, columns and other designs, it is usually the need of load-bearing structures. It cannot be demolished at home, otherwise it will cause damage to the overall building safety. Therefore, the original structure of the underground space is as simple as possible (because of the wall, The smaller the partition caused by the column, etc., the better).
Second, the original ventilation method. If it is a semi-underground space, the basement itself is designed with a window type, although the ventilation effect is not as good as the above-ground room, but the design of the window can certainly bring certain natural lighting and ventilation effect, for the subsequent artificial improvement of ventilation effect, the basic conditions of the house type Still better, it is more beneficial to the health of the owners.
Third, pay attention to the window enclosure of the semi-basement. There is usually a fence outside the window of the semi-basement, and there is a cover above the window of the enclosure and basement. The industry mainly pays attention to whether the design of the enclosure and the cover in the original design can effectively ensure the ventilation, dust-proof and safety functions of the semi-underground space. If not, it needs to be improved during the home decoration process, and the gauze is added to cover the ground dust and leaves. Wait.
