Carpet Surface Installation Quality Control
Quality control for carpet surface install: substrate prep, cutting, gripper strips, backing seams, power stretching and modular tile layout.
Key quality control points for carpet surface installation:
Substrate preparation
The substrate must be flat and clean—no pits, pockmarks or cracks. Low spots should be filled level with cement mortar before install.
Cutting dimensions
After cutting, each carpet run should be about 20 mm longer than the room length. Width is measured after trimming the edges; mark and cut the edges accordingly.
Gripper strip fixing
When fixing with gripper strips, install strips around the room perimeter 10–20 mm from the corners, secured to the substrate.
Backing seams
Join carpet on the backing by sewing or tape. Joints must be firm and flat. After joining, trim uneven pile on the face at the seam with an electric edger.
Power stretching and modular layout
Use a power stretcher to tension the carpet in both directions, section by section, until flat and tight. Force must be moderate—too much can tear the carpet, too little leaves ripples. Work progressively. For modular tiles, lay a cross control pattern at the room centre first, then work outward from that grid.
