Power Curbers acquires Miller Formless: what the expanded slipform range covers
In August 2025, Power Curbers Companies completed the acquisition of Miller Formless Systems. For contractors specifying concrete slipform equipment, the practical question is not the transaction itself but what the combined product range now covers — and what still needs to be confirmed before a machine is selected.
What happened
Power Curbers Companies finalised the acquisition of Miller Formless Systems on 29 August 2025. Miller Formless, founded in 1970 and based in McHenry, Illinois, produces mid-sized slipform machines.
Miller Formless continues to operate under its own brand name. Power Curbers Companies now holds four brands: Power Curbers, Power Pavers, Anvil American and Miller Formless.
In its announcement, Power Curbers stated that the acquisition introduces operational efficiencies intended to benefit customers in machine delivery, parts availability and after-sales support. This is a statement about the combined company's operations. It is not a commitment about lead times or service levels in any particular country, and it should not be read as one.
What the combined range covers
Power Curbers president Stephen Bullock identified three machines when describing the expanded lineup: the Power Curbers 5700-D multi-purpose machine, the compact Miller Formless M1000, and the Miller Formless M8800 barrier machine. Taken together, the group describes a range extending from extruded curb machines to mainline highway pavers.
Two Miller Formless machines are directly relevant to barrier and larger slipform work:
The M-8800 is described by Miller Formless as its largest concrete paving machine. It pours barrier walls and bridge parapet walls up to 102 inches (2.59 m) and paves up to 20 feet in straddle configuration. It is a four-track machine and can be configured for right- or left-hand pouring.
The M-8100 is a versatile four-track slipform paver covering curb, curb and gutter, barrier wall, parapet and ditch profiles.
A note on one claim that circulates in secondary coverage: the M-8800 is sometimes described as the world's largest slipform paver. Miller Formless's own wording is narrower — it is the company's largest concrete paving machine. The distinction matters when a machine is being specified against a tender.
Why this may matter for a project in Uzbekistan
For a contractor evaluating concrete profile work, the useful consequence of a wider range is that curb, gutter, barrier, parapet and full-width paving no longer have to be approached as separate supplier decisions.
That said, the machine class is decided by the work, not by the manufacturer's corporate structure. A project producing repetitive roadside profiles — curb and gutter, drainage channels, irrigation sections, safety barrier — is a different equipment question from a project paving a slab across a full carriageway width. The first points toward the Power Curbers 5700 platform or a Miller Formless machine; the second points toward the Power Pavers SF range.
For projects in Uzbekistan, the evaluation may also need to consider concrete supply continuity over long haul distances, high summer temperatures affecting the placing and curing window, transport and axle limits on the mobilisation route, and the availability of line-and-grade control appropriate to the site.
What still requires confirmation
An acquisition announcement does not establish that any specific machine can be supplied into a specific market. Before a model is specified, the following should be confirmed directly:
- whether the exact model and configuration is currently in production
- which mould and profile options apply to the required cross-section
- what emissions configuration and documentation apply for import
- current lead times, which the manufacturer has not published
RENTEK can review the project requirement and clarify applicable equipment options and manufacturer availability.
