One、Ground heating construction preparation
1、The flatness requirement for the heating floor is within ±10mm. If the flatness is not met, the substrate should be leveled using appropriate methods from the civil engineering phase, and loose sand should not be used for leveling.
2、The leveling layer should remain dry.
3. After completion of construction, promptly clean up construction debris and maintain a clean surface.
II. Flooring Heating Construction Process Flow
Material Arrival → Material Inspection → Inspect Work Area → Install Interface Treatment Agent → Laydown Phenolic Boards and Reflective Membranes → Laydown Cross-Linked Pipe Ring → Connect Interface Treatment Agent → Install Expansion Joints → Install Pressure Gauge → Pressure, Density, and Strength Test → Interim Acceptance → Backfill with Concrete → Secondary Pressure Check → Construction Completion Acceptance → Project Completion Acceptance.
III. Installation Construction Method for Ground Heating
1. Clean the floor surface.
Clean the side wall and ground joint, ensure the ground surface meets the construction requirements, and remove temporary supports and lifting points.
2、Install insulation at corners and edges.
According to the design requirements, insulation layers must be installed at the building corners, ensuring that they are horizontally aligned during installation. When encountering other pipes or conduits passing through the wall, their shapes must be cut to accommodate them, and no cracks should be present.
3、Insulation layer installation
Lay insulation boards according to the length and width of the installation area, ensuring that the edges are aligned. If the boards or walls form a right angle, they should be cut and fitted to match the shape.
4、Laying of wire mesh
The wire mesh laid on the insulation layer should be smooth and aligned. Securely fasten it together using plastic zip ties to create a single unit.
5、Underfloor Heating Pipe Installation
The underfloor heating pipes must be laid according to the spacing, length, and direction specified in the design and construction drawings. The heating pipes must remain horizontal and should not exhibit "dead bends" or lateral distortion.
6、Installation of drain/collection devices
Install the diverter/collector according to the specified location in the drawings. Ensure that the diverter is positioned above and the collector is positioned below. After installation, secure it with expansion bolts.
7、Hydrostatic pressure test
After the underfloor heating system is installed, it must undergo a water pressure test. During the pressure increase, it is necessary to constantly observe and check for any leakage.
