Cellular grout is an alternative name for 

cellular concrete fill

. Cellular concrete is a type of controlled low strength material (CLSM). CLSM generally refers to flowable fill or mix designs specifically formulated for relatively low, but predictable, strengths. The “cellular” in cellular grout refers to the preformed cellular concrete foam used to generate the material. Instead of sand and stone aggregate, Low Density Cellular Controlled Low Strength Material has uniformly-distributed air bubbles. Sometimes sand is used, but it’s at much lower quantities per cubic yard than traditional CLSM. This lowers unit weight significantly. Foaming is done either through truck batching or continuous generation.

At Superior Grouting, we understand that when it comes to pressure grouting, there are different types of cellular grout available. Depending on your project’s specific needs, you may require either pervious or non-pervious material.

When it comes to backfill and cellular grouting, we have the expertise to get the job done right. We understand the importance of density of lightweight grout and its impact on your project’s success.

The annular space between the carrier and the host pipe must be filled with the right type of cellular grout. By using cellular grout, the grout is considerably lighter than sanded grout while still maintaining its strength.

One crucial factor we consider when using cellular grout is deflection. Our team of experts knows how to prevent deflection from causing damage to your project by selecting the correct mix design. We pride ourselves on our commitment to providing top-quality service and solutions to our clients, saving them time and money while ensuring safety and reliability.

At Superior Grouting, we understand that when it comes to Pressure Grouting Services, our clients have specific needs and concerns. That’s why we offer a range of Cellular Grouting Services, including the use of Lightweight Cellular Grout and 

Cellular Cement

. There are two primary drivers for using this innovative material: Load Reduction and Placement Characteristics.

On the Lightweight side, Cellular Concrete is ideal for Load Reduction. Alongside this, 

slurry grouting

 is another technique that can be considered depending on the project requirements. Typical lightweight mass fills are installed around 30lbs/cuft, making them a great solution for projects where weight is a concern.

Low Density Cellular Concrete

Low Density Cellular Concrete (LDCC) can be used for 

load reducing backfill

 to reduce overburden and evenly distribute loads over poor soils. LDCC offers significant advantages in projects that require lightweight fill.

Load reducing fills are commonly used in 


 like the following:

  • Bridge Approaches and Ramps over unstable soils
  • Retaining Wall Backfill
  • Trench Backfill
  • Abandoning Structures and Pipelines
  • Mechanically Stabilized Earth (MSE) Walls

Densities can be varied from 30 to 90 PCF and compressive strengths from 50 to 900 PSI. In addition, it is also available in a pervious or impervious formulation. Mix design can be specialized for specific location and geomaterial behavior.

Meanwhile, on the Placement Characteristics side, Cellular Grout is used due to its Lower Density, flowability and unique economic benefits. It can be pumped very far (thousands of feet) at very low pressures, which makes it perfect for Utility Grouting Applications. This facilitates annular space grouting and abandonments of much longer runs compared to traditional grout materials.

We understand that every project is unique, which is why we offer customized solutions to fit your specific needs. Our team of experts has extensive experience in using Lightweight Cellular Grout in a variety of applications. We know that cellular grout is lighter than traditional options, making it an excellent choice for projects where weight reduction is a priority.

At Superior Grouting, we are committed to providing top-quality service and solutions to our clients. We understand the importance of safety, reliability, and value, which is why we are dedicated to problem-solving and providing value to our customers. We have a proven track record of successful projects and satisfied customers, and we would be honored to add you to our list of success stories.

At Superior Grouting, we specialize in providing top-quality Pressure Grouting Services for government agencies and large corporations in Houston and other near areas. We work with owners and contractors to develop project solutions that meet their unique needs.

Our neat mix cellular grout is generated using a straight slurry with a water : cement ratio of 0.50- 0.70. We blend the slurry grouting onsite with pre-formed foam, either in a ready mix truck or in-line, depending on the project volume and other constraints. Our foaming agent requires no consolidation, which saves time and money while ensuring safety and reliability.

Cellular concrete typically ranges from 30lb/cuft wet cast density up to around 90lb/cuft, providing strengths from around 50psi to greater than 1,000psi. Density is infinitely variable within that range, and there is a relatively linear relationship between density and compressive strength. Our relatively common mixes are 40PCF, 45PCF, and 55PCF. We use 30PCF wet cast density for maximum load reduction. In areas where low unit weights are required, and buoyancy can’t be balanced by overburden, we use pervious cellular grout. For pipe abandonments, annular space grouting, and other utility-related work, we use the relatively common mix of 45PCF.

At Superior Grouting, we are committed to providing our clients with the best solutions to their unique problems. Contact us today for more information or to request a quote.

Sanded mixes are used to economically achieve high wet cast densities. The base slurry for sanded cellular grout consists of around 2,000 pounds of sand per cubic yard, 600 pounds of cement and around 800 pounds of water.

A limitation of using sanded mixes is flowability; sanded cellular concrete can’t be pumped nearly as easily as neat mix cellular concrete. When specifying cellular grout, it’s best to leave the mix design up to the specialty contractor. Typically, specified characteristics are a wet cast density that’s +/- 135lb/cuft, and with strengths ranging from 800-2000 psi at 28 days.

Cellular grout is an engineered portland cement slurry combined with precise amounts of density controlled foam. The portland cement slurry and foam are mixed producing a lightweight mixture containing uniformly distributed air cells. In it’s rigid form it can be thought of as cement based grout
having air as the aggregate. Density can be varied from 30-90 lb./ft3. Compressive strength ranges from 50 to 1000 psi. are available. Cellular grouting is becoming more and more commonly used and accepted within the engineering and construction community as a technology for filling voids. Some
relevant applications include but are not limited to: line abandonment, annular space grouting, contact grouting, annulus space grouting, decommissioning and abandonment of underground tanks and structures, load reducing backfill and voided slab fill.
