A 120 ton ground mat is an HDPE or composite panel rated to support ~120 t of plant or crane load (always verify against subgrade — the mat rating is only half the story). For 120 t work, specify thick HDPE (20 mm) with UHMWPE wear layer, or solid composite (38–47 mm); YASU and similar manufacturers market 120-ton-class HDPE mats. The governing calc remains ground bearing pressure = load ÷ (pad area × floats) — a 120 t crane on four outriggers at 30 t each needs pads dropping pressure below safe CBR. On soft ground, add geogrid. Solid composite is the safer choice as loads approach the ceiling.
"120 ton mat" is a headline number buyers search — but the real question is whether the ground beneath can take it. This guide pairs the mat spec with the subgrade math.
Mat Spec for 120 t
| Option | Build | Note |
|---|---|---|
| Thick HDPE + UHMWPE | 20 mm HDPE, wear layer | YASU-class 120 t HDPE |
| Solid composite | 38–47 mm HDPE/UHMWPE | Safer near ceiling |
| With geogrid | + underlayment | Weak subgrade |
The 120 t Calculation
- Crane 120 t, 4 outriggers → ~30 t per float at max radius.
- Pad 1.2 m × 1.2 m = 1.44 m² → pressure = 30 ÷ 1.44 ≈ 20.8 t/m².
- Safe soil bearing typically 0.5–2 t/m² (unprepared) → pad is 10–40× over.
- Fix — larger pad and/or thicker composite + geogrid to reach safe pressure.
HDPE vs Composite at 120 t
| Factor | 20 mm HDPE+UHMWPE | Solid composite |
|---|---|---|
| Ceiling | ~120 t (rated) | 150–200 t |
| Margin | Tight at 120 t | Comfortable |
| Weight | Lighter | Heavier |
| Cost | Lower | Premium |
When 120 t HDPE Is Enough
- Firm subgrade, verified CBR.
- Load centred, not at extreme radius.
- Single lift, not sustained haul.
- UHMWPE wear layer for abrasion.
When Step to Composite
- Load approaching 120 t on soft ground.
- Sustained/heavy cranage or haul.
- Contamination-sensitive (sealed core).
- Need margin for unknown subgrade.
Procurement Note
For 120 t-class work, factory-direct HDPE+UHMWPE or solid composite at 30–50% below branded is viable — but insist on the third-party 120 t (or higher) compressive test and the subgrade calc. Never trust a brochure number at this load.
Frequently Asked Questions
What mat holds 120 tons?
Thick HDPE (20 mm) with a UHMWPE wear layer, or solid composite (38–47 mm). YASU-class 120 t HDPE exists; composite gives more margin near the ceiling.
Is a 120 t mat enough on soft ground?
Only with proper subgrade prep — the mat rating is half the story. Calculate ground bearing pressure; on weak soil add geogrid and/or step to composite.
HDPE or composite for 120 t?
HDPE+UHMWPE is lighter and cheaper at rated 120 t; solid composite is safer as loads approach the ceiling or on soft ground. Verify the compressive test either way.
