Using Prefabricated Slabs for House Sinks
Houses can use prefabricated slabs to make sinks, with specific methods and characteristics as follows:

I. Casting U-shaped drainage channels in-situ using flow channel molds
The flow channel mold is made of thickened steel formwork and features a smooth assembly process through a splicing design, allowing for single-person operation. Its core advantage lies in its ability to simultaneously produce two rectangular channels and install cover plates. The design of the cover plates combines practicality and safety: they can withstand the load of people walking and effectively prevent debris from falling into the channels. The mold has a short demolding time, allowing for demolding the day after cement pouring. The resulting channels have straight lines and smooth surfaces, meeting the precision requirements for drainage facilities in engineering projects. This in-situ casting method allows for flexible adjustment of channel dimensions based on the actual drainage needs of the house, making it suitable for scenarios requiring customized drainage systems.
II. Selecting ready-made concrete U-shaped troughs and other prefabricated sink cover plates
Standardized concrete U-shaped trough prefabricated components are already available on the market and can be directly used as the main body of the sink. These products have the following characteristics:
- Variety of specifications: Different manufacturers offer a variety of size options to match different drainage volume requirements. For example, products from Qufu Songli Electric Power Engineering Co., Ltd. are priced by area (≥1 square meter/¥80.00), while those from Chiping Chengnan Limin Prefabricated Parts Factory are priced per piece (≥1 piece/¥60.00). This difference reflects variations in product specifications or additional services.
- Ease of installation: Prefabricated components are industrially produced with high dimensional accuracy, requiring no complex adjustments during on-site assembly, significantly shortening the construction period.
- Structural stability: Concrete materials have high compressive strength, enabling them to withstand long-term water flow impact and external loads, making them suitable for use as drainage systems around the house or underground.
III. Application scenarios and selection recommendations
If the house's drainage system needs to be constructed simultaneously with the main building and has special requirements for channel shape, the flow channel mold in-situ casting method is recommended for its flexibility in meeting personalized design needs. If construction efficiency is a priority or there is a need to quickly replace aging drainage facilities, prefabricated concrete U-shaped troughs are more suitable, especially for standardized residential or existing building renovation projects. When purchasing, it is important to verify the load-bearing grade of the product to ensure that the cover plate's load-bearing capacity meets the requirements of the usage scenario. Additionally, compare the price inclusions of different manufacturers (such as transportation and installation guidance) to optimize cost investment.
