You’ve seen retaining systems used in slope stabilization, embankment reinforcement, road construction, riverbank protection, and erosion control. For years, we’ve mainly relied on concrete retaining walls and other rigid concrete structures. Now, as the industry increasingly demands sustainable infrastructure, reduced project costs, and faster installations, HDPE geocell systems are emerging as the go-to alternative to concrete on many projects across the globe!

But which is best for your project—HDPE geocell versus traditional concrete retaining systems?

Let’s compare them from the design, cost, environmental, and construction perspectives.

What is an HDPE Geocell?

HDPE geocell is a three-dimensional expansible honeycomb-like cellular confinement system manufactured from high-density polyethylene sheets welded together by ultrasonic technology and then expanded on site. The cells are subsequently filled with soil, gravel, sand, or concrete to provide stable load support.

Due to its flexibility and confinement performance, geocell is used extensively for:

• Slope protection
• Base stabilization
• Retaining wall reinforcement
• Erosion control
• Channel protection
• Risley and road/rail subgrade reinforcement
• Driveways and parking
• Mining haul roads

In contrast to rigid retaining structures, geocell provides performance by laterally distributing loads and enhancing the mechanical performance of infill materials.

You may also hear concrete systems called “retaining systems.” This generally refers to rigid concrete structures designed to resist lateral earth pressure.

Examples tend to be:

• Reinforced concrete retaining walls
• Gravity retaining walls
• Cantilever retaining walls
• Precast concrete block walls
• Cast-in-place concrete slope systems

Concrete retaining systems have a long history of being used because of their high compressive strength and long-lasting properties when dealing with heavy loads.

HDPE Geocell vs Concrete Retaining Systems: Major Differences

Structural Flexibility

A major difference between geocell and concrete systems is flexibility.

HDPE geocell systems are flexible and can adjust to slight ground settlement without cracking. This is key in soft soil applications, mining sites, road embankments, and areas subject to freeze-thaw cycles.

Concrete retaining systems are rigid. Once breaking of the system occurs due to differential settlement or soil movement – repairs can become costly and troublesome.

For a variable base or poorly compacted earth – geocell confinement systems typically have better medium/long-term adaptability.

Speed of Installation

Typically, the installation of geocells if faster and easier.

Lightweight, folded panel during delivery to site means workers need simply expand each cell, fixing it in place – then filling with local material such as gravel and soil.

Concrete systems require;

• Excavation
• Formwork
• Steel reinforcement
• Pouring
• Curing time
• Heavy machinery

This greatly conspires to swell the time-line of the project.

Labs, roads, transportation time, etc. are pricey, and in a mountain area where costs are astronomical, geocell systems will enhance installation time greatly.

Transportation Costs

Transportation is a linked key.

As HDPE geocell boards are tiny “pre-expanded” and miniaturised before delivery – large amounts can easily be brought in.

With concrete retaining systems-concrete, aggregate and reinforcement steel and large precast comes at the expense of being transported with; large amounts of heavy machinery.

This makes it difficult to economically move – paths and roads can be a nightmare for sales dedicated/focussed upon, to a country that is remote or rocky.

For ‘export’ sales – typically these geocell products are more democratic to ship internationally.

Load Distribution Performance

Geocell technology enhances load support through the confinement of infill materials inside their interconnected cells.

This confinement effect:

• Reduces lateral movement
• Acts against the tendency of aggregate to rut
• Additionally enhances the bearing capacity of the road or base
• Enhancing the stability of the soil and base in general

In general road construction projects and various base stabilization, geocell systems allow for less thickness of aggregate while still allowing proper load transmission and road performance.

Concrete systems, on the other hand, rarely allow their load to be transmitted through soft soil material in the same manner, relying more on rigid structure.

In many cases, geocell offers better engineering efficiency through this confinement effect.

Drainage Performance

Drainage systems are critical to the stability of retaining walls.

Perforated geocell systems allow water to drain through the structure reducing the chance of poor hydrostatic pressure developing behind slopes and walls.

Concrete such retaining walls frequently have a need for extra piping systems to facilitate drainage of water build-up behind the wall, such as:

• Weep holes
• Drainage piping
• Filter layers

Failure to provide adequate drainage behind the concrete can result in pressure build-up behind it and render it impotent to resist lateral forces.

In erosion control and slope protection project, geocells almost always perform better in managing water. The natural way of doing things.

Environmental Impact

Environmental impact on construction is becoming a more prevalent factor on infrastructure projects.

HDPE geocell systems offer a lot of green solutions advantages:

• Reduction in concrete requirements
• Rely less on carbonated concrete systems
• Ability to use local fill materials
• Naturally support vegetation better
• Reduce erosion of soil

“Soft” vegetated geocell type slopes can be blended into the earth naturally on highways, parks, river banks etc.

Concrete systems on the other hand are non-upermeable and tend to have a higher embodied carbon demand.

Countless places nowadays, due to our understanding of global warming and with a plethora of green construction standards, authorities are now opting for concrete alternative solutions offered by geocell construction tech.

Long-Term Maintenance

Geocell systems resist –

• U.V. aging
• Chemical and biological corrosion

Installed correctly, these systems can provide extended life through low maintenance.

Damaged concrete in walls can lead to:

• Cracking of the surface
• Spalling of the face
• Corrosion of reinforcement
• Water damage

The repair of damaged concrete can cost a great deal of money.

When are the geocells preferable to concrete?

For Slope Protection Projects

Geocells confine the soil and permit growth of vegetation to occur and this is an application widely seen on slopes of highways, embankments of railways, and in mining operations.

For Erosion Control

The confinement of honeycomb doing its thing stops soil being washed away by rain and flow of water on the surface.

Road Base Stabilization

When used as reinforcement of road base on weak and compressible subgrades, geocells improve their bearing and result in less aggregate required.

For Highways in Remote Location

(the transport vehicles can have lighter loads) and can be quickly installed.

Difficult remote sites are perfect for geocells.

Environmentally, Bank work is now supported by recovery of the native landscape and the geocell promotes green infrastructure being introduced.

When are Concrete Retaining Systems still necessary

The” very high” walls and heavy load zoning of some industrial buildings, urban structural retaining projects which necessarily must have a rigid-type structure in place, the very heavy water retaining structures make concrete attractive.

Some engineers even build geocell systems, then erect concrete structure all around.

How to Choose the Correct Geocell

Several technical factors have to be looked at when deciding just which the correct geocell to use is.

Geocell heights

Some of the heights available on the market are:

• 50mm
• 75mm
• 100mm
• 150mm
• 200mm

The most common are 75mm high.

HigherPerforated vs Non-Perforated Geocell

A perforated geocell improves both drainage and friction interaction.

Many performance requirements can utilize geocell in both smooth and perforated configurations.

The non-perforated geocell is ideal for projects where the goal is water containment or other engineering requirements exist.

Textured Geocell

Texturing can increase the friction between the cell wall and the fill material.

This can create a more stable system.

Weld Strength

The weld of the geocells will be critical if we are to deliver years of performance under load and being site-friendly.

Why More Contractors Are Making The Switch to Geocell Systems

Contractors and engineers alike for the past ten years have made the switch to geocell once they have found it the much more narrow easier and better performing option that means lower overall project cost, the system is faster to construct, it’s a much more slender and lesser carbon footprint of a labor requirement, and it adapts itself much better on weak soils, and it helps the environment, and lower the cost of transportation, and deliver long term durability.

For the majority of today’s projects geocells are up to the task. You balance accordingly.

Fred When told the problems only just below the surveyor did the geocomposite systems play indeed their part in Civil engineering systems and somes.

Depends of course on the conditions on site, may have site ston the characteristics of soil, the rest of the loads, the weight of the environmental an issue, and the budget.

SNR system as concrete retaining stem do ok governance for heavy duty structuring where do the real job but in the HDPE world geocomposite systems the advantages in the flexibility, erosion control, slope stability and economy off pile up as they’ve become all the more preferable in earth, swing the net in, and through the concerns for sustainability and build one of the largest above as laters quite foind the geocell expediation.

If you like more to do or a reliablgeocell manufacturer or supplier, choose HDPE geocell with stable welding quality with engineers it would make and facilitate a good project and built to last.
