Cold Room Panel Floor Design, Load Bearing & Moisture Barrier for Forklift Operation

Cold room floor panel bears pallet, forklift and stacking cargo load; floor structure is the most easily neglected part of cold room insulation design. Light pedestrian cold room: standard PU floor panel with reinforced surface; forklift working cold room needs concrete load layer above insulation. Typical floor structure from bottom up: compacted ground → PE moisture barrier film → PU insulation panel → steel mesh reinforced concrete layer. Moisture barrier film (0.2mm PE) must be fully overlapped and sealed; underground water vapor rising penetrates foam and makes insulation fail. Xiteliduo cold room PU floor panel HS 940600 adopts high density PU core, special wear-resistant surface for light load cold room. Low temperature cold room floor needs anti-heave design; soil water freezing under floor will expand and push floor upward, crack concrete and panel. Heating wire under floor insulation is the mainstream anti-freeze heave solution for -18℃ and below cold storage, keep subsoil temperature above 0℃. Floor drainage trench inside cold room must be heat isolated; trench without insulation forms heat bridge and frost block frequently. Floor expansion joint is reserved for concrete layer; temperature shrink and expansion will crack floor slab without reserved joint. Refrigeration maintenance & repair company checks floor surface crack and local bulge; bulge is typical signal of subsoil frost heave.

FAQ

1. What is the function of PE moisture barrier film under floor panel? Block underground water vapor from entering PU foam.
2. What structure is needed for forklift cold room floor? Insulation panel plus reinforced concrete load layer.
3. What risk for low temperature cold room without floor anti-heave measure? Underground water freezes, volume expands and floor bulges/cracks.
4. What is the common anti-frost heave method for frozen cold room floor? Lay heating cable under insulation to keep soil above zero.
5. What is the standard thickness of moisture barrier PE film? 0.2mm, overlap and seal all joints.
6. Can ordinary wall PU panel be used directly as forklift floor? No, insufficient compression resistance and wear resistance.
7. What special design for cold room internal drainage trench? Independent thermal isolation to avoid heat bridge.
8. What symptom indicates subsoil frost heave? Local floor bulging and concrete crack.
