Slipform Concrete Construction

Central PA businesses rely on slipform concrete construction for a wide variety of projects and applications. First developed as a method for building vertically rising agriculture structures such as silos and grain towers, concrete slipforming has been an effective technique used for decades on everything from high-rise buildings to single-family homes. It’s a continuous, no-seam production method with quick-forming properties that yield exceptionally sound and sturdy structural performance.

Slipform Concrete Construction Saves Time and Money

In the past few decades, much of the expansion and growth in the construction industry and the proliferation of building super-high-rise buildings and long-span road and bridges have a direct correlation with the development of high-performance and high-strength materials. Materials such as slipform concrete have played a significant role in the breadth of innovations achieved in design and construction technologies.

The concrete slipform method offers architects, engineers and contractors a productive technique for the construction of numerous structures. Slipforming enables the construction of a variety of concrete structures of various sizes, geometric shapes and cross sections. It can construct multiple inserts and openings with strict geometric tolerance quicker than convention concrete construction.

The monolithic or joint-less structure generated by the process has enabled slipform paving to become a key solution for a variety of applications, including dolly pads, sidewalks, curbs, barrier walls, concrete road pavements, airport aprons, runways and more. The automated slipping of the forms allows 24-hour continuous placing. Consequently, slipform concrete services reduce the project duration significantly compared to other techniques.

What is Slipform Concrete?

The key to slipforming concrete has to do with the quick-setting properties of the concrete. The concrete must have the proper consistency, which allows it to flow into the form. Using vibration, the mix must consolidate quickly enough to emerge from the form with strength.

The strength of the newly set concrete must also allow the forms to bypass the concrete without interference. The prior concrete section must also support the pressure of the new concrete, withstand the vibration of the compaction equipment, and resist collapse.

Types of Concrete Slipform

The two types of slipforming are:

  1. Horizontal slipforming — This procedure was initially developed and deployed by the Interstate Highway under the Eisenhower Administration during the 1950s. slipform-pavement-contractors-pa
  2. Vertical slipforming — The method may surround the concrete form by a platform from which workers place steel reinforcing rods into the concrete to facilitate a smooth pour. Hydraulic jacks are used to raise the concrete form and working platform. Typically, the form raises at a rate that allows the concrete to cure by the time it comes out at the end of the form. R.J. Potteiger does not offer vertical slipforming services at this time.


The Development of Slipform Paving

The two most common methods used for the paving of pavement-quality concrete are the fixed form method and the slipform method. In fixed form construction, workers must erect the form at the edge of the pavement lane prior to paving operations.

03_concrete-contractorsWorkers must remove the formwork after the concrete has hardened, which may be 24-48 hours after construction. Essentially, the erected forms must support the edges during the hardening stage.

In the early 1960s, slipform paving remained somewhat of a novelty in the construction industry. The method need to overcome early challenges, such as: It was limited to non-reinforced slabs Many in the industry doubted if slipform methods could conform to surface conformation a

  • It was limited to non-reinforced slabs Many in the industry doubted if
  • Many in the industry doubted if slipform methods could conform to surface conformation and tolerances
  • Equipment manufacturers had yet to catch up with the construction technique


However, the need for a less labor-intensive construction method, the state of the economy, and the expansion of interstate highway systems fueled the growth of slipform paving. Innovation and collaboration with paving contractors, equipment manufacturers and government highway agencies in the late ‘60s and early ‘70s played a key role in developing solutions.

In the slipform method, the formwork attaches to the paver and moves along with the machine during operations. The compaction and finishing of the concrete occurs within the length of the machine. The formwork provides a temporary support structure for the slab. The mixture of the concrete and the vibration ensures the material does not slump yet remains in a plastic state.

Successful slipforming construction requires a host of interdependent elements to come together, including proper planning, a well-designed concrete mix (consistency and predictable properties), and a distribution system that facilitates uniform and timely delivery of all components.

The Benefits of Slipform Concrete

The slipforming concrete construction concept has exhibited a significant impact on the economics of concrete construction projects. The technique increases productivity per person per hour, creates efficient usage of materials, and allows for a more appealing finished product.



Jobs That Need a Slipform Paver

From concrete barrier walls to paving and more, slipform concrete construction offers viable and economical solutions for a variety of commercial and industrial projects. Industrial parks and new residential streets are also ideal for slipform paving. Concrete pavements can deliver a service life of over 30 years, requiring minimal maintenance and reducing environmental impact.



Slipform Paving Equipment

As the most commonly used method in concrete paving construction, slipform paving consolidates screeds and initially finishes the concrete in a single continuous motion, without the need for forms. The equipment used for modern slipform paving consists of the extrusion-type process, a process that forces, pressures or pushes material through a die to create the desired shape.

Slipform construction does not require forms. Therefore, the concrete must be able to hold the pavement edge. This requires concrete with the appropriate slump. The process is super-efficient and provides smooth concrete pavement.

Here are a few of the machines commonly used in slipform paving operations:

Concrete Placing Machine or Placer/Spreader

This machine receives the concrete from the delivery vehicle. It places and spreads the material in front of the second machine, the slipform paver. If the delivery driver can place the concrete directly in front of the slipform paver, it eliminates the need for the placing machine.

Slipform Paver

Using an auger, the slipform paver spreads the concrete uniformly across the paving area. The process consolidates the concrete with spud vibrators. The machine strikes off the top of the concrete to the appropriate level. The concrete feeds into the mold that configures the pavement into the correct geometric shape. Some slipform concrete pavers have tamping bars that slightly tamp large aggregates on the surface of the concrete slab. This prevents the paver mold from catching the aggregate and ripping the top of the slab.

The machine has the capability to spread the concrete uniformly and strike off the concrete to the required section. It relies on a power-driven device, such as a reciprocating blade, auger or screw conveyor, or a belt conveyor, and will not lose traction.

Slipform paving equipment components and features depend on the particular machine manufacturer.
