Placing FAQs

Where do I purchase cellular concrete?

Cellular concrete is purchased from and installed by specialty contractors who have factory training in the field of cellular concrete installation. These contractors also have access to a Cellular Concrete LLC jobsite tough Foam Generator. These specialty contractors purchase their liquid foam concentrates directly from Cellular Concrete LLC.

How is cellular concrete placed?

The pre-formed foam is added to the cement slurry and mixed in the concrete mixer or in a continuous process. From that point, cellular concrete is placed in any way that a fluid mix can be transported. Pumping is the most common method of placement. Tailgate ready mix truck delivery, bucket cranes, wheelbarrows, hand carried buckets and any other acceptable method of delivering a fluid mix works well. Mearlcrete® and GeofoamTM mixes have been successfully pumped up to 500 ft. vertically, and 10,000 ft. horizontally without breakdown or segregation problems.

Can cellular concrete be under mixed?

The cement and water slurry should be mixed until there are no dry clumps or balls of cement. The pre-formed foam mixture is then added into the mixture. The foam mixes quite rapidly into the slurry and only requires modest mixing times depending upon the mixing equipment.

Can cellular concrete be over mixed?

Mixing until there is a reduction of volume of product is not recommended. Air cell stability is the mark of Mearlcrete® and GeofoamTM liquid foam concentrates and our Cellular Concrete Foam Generators. With typical mixing procedures, cellular concrete formulated with Mearlcrete® and GeofoamTM pre-formed foam is very stable even with modestly extended mixing times.

How far can cellular concrete be pumped?

Cellular concrete is a very easily pumped, highly fluid mixture. The bulk of cellular concrete is placed by pumping. Cellular concrete typically will move through the pump lines using less pressure than typical heavier grout mixes. Documentation of cellular concrete being pumped up to and exceeding 500 ft. vertically and 10,000 feet horizontally is commonly available.

How do you finish cellular concrete?

Most cellular concrete is left to self-seek a level and not surface “finished” in the traditional sense. Much cellular concrete is covered by another material. A floor overlayment type smoother tool can be used simply to break the surface air cells and create a more uniform and polished look to the surface in the rare case when a more uniform surface appearance is desired.
