Golmud No.3 Middle School (2024) — high-altitude installation

Quick answer: Modular flooring installation has 6 key steps: 1) base check (flatness + slope); 2) color & direction planning; 3) lay from center outward; 4) reserve 2-3cm perimeter expansion gaps; 5) line marking; 6) edge finishing. The most common failure is expansion gaps — 90% of summer buckling comes from insufficient gaps. A standard 5v5 court (420㎡) takes 2-3 days with 3 crew.

6-Step Process

  1. Base check: flatness ≤5mm/3m, slope 0.3-0.5%, cracks <5mm
  2. Color/direction: CAD pattern for multi-color; seam offset 1/2 for large tiles
  3. Center-out laying: keeps the main court tiles whole, cut tiles at edges
  4. Expansion gaps: ≥2cm perimeter; 5mm every 15m for large courts
  5. Line marking: color tiles (never fade) or outdoor paint
  6. Edging: aluminum or plastic edge strips

Common Mistakes

Insufficient expansion gaps (90% of buckling), corner-start laying (line misalignment), unleveled base, no edge finishing, skipping the water test. After install, follow maintenance.

FAQ

Need professional installers?

Factory or factory-trained crews recommended — gaps, direction, lines and edging have details outsiders miss.

Lay over old silicon-PU?

Yes if flat with no bubbling/delamination; otherwise repair base first.

Install in winter?

5-40°C OK; below 0°C not recommended (lock brittleness). Northern projects best in spring/autumn.

Usable after install?

Immediately — no glue cure. 24h light use recommended to adapt to temperature.

Installation cost?

Industry norm 20-40 RMB/㎡; small courts a flat 2,000-5,000 RMB.
