At Conco we are always looking for ways to provide our customers with cost-effective solutions that result in the best-finished products. Our ConFoam™ concrete foam is just such a solution. It offers many benefits including the fact that it can be produced at a weight that is much less than native soils or compacted base material and eliminates the need for costly foundation treatments. Additionally, it does not require mechanical compaction so it has no impact on retaining structures or deep foundations.

The fill material can be easily recycled and reused. Furthermore, since it requires fewer raw materials and eliminates or reduces the need to excavate and transport large quantities of aggregate, it is less expensive to produce.

ConFoam’s™ high-tech solutions:

• We have specialized production equipment and highly trained crews to safely and skillfully place the highly flowable, lightweight concrete.
• Self-leveling ConFoam™ offers the ability to fill voids in the most challenging locations as well as to enhance the load-bearing qualities of poor soil.
• By adding fine and/or coarse aggregate, fly ash, and admixtures as well as various foaming agents, we can produce foam concrete with increased strengths and higher densities if your project requires

The Benefits of ConFoam™ in Swimming Pool Demolition

As an addition to our comprehensive roster of concrete services, Conco also provides swimming pool demolition and backfill services. Through the use of our proprietary foam concrete, ConFoam™, we are uniquely positioned to offer fast, cost-effective pool demolition. ConFoam™ is a highly flowable, cement-based slurry that is useful in a variety of applications and saves you time and money over other swimming pool backfill materials.

• Reliable expertise – Our experienced teams are experts in ConFoam™ production and trained in its skilled and expedient pumping and placement.
• Compliance with pool demolition requirements – ConFoam™ is an approved “clean fill” and complies with regulations regarding Demolition, Drainage, and Compaction Plans for post-demolition building on the backfilled area.
• Reduced installation time – With the ability to place 500 cubic yards of ConFoam™ in 8 hours, our teams can complete a pool backfill project in one shift.
• Hassle-free compaction – ConFoam™ is a self-compacting material that achieves compaction 24 hours after placement. No need for the additional time or equipment required to compact other backfill materials like soil or gravel.
• Lightweight alternative – ConFoam™ reduces loads on retaining structures and is ideal for use on poor soils due to its lightweight characteristics.
• Safer placement – ConFoam™ reduces job site safety risks because its placement does not require employees to enter the excavated area.

At The Conco Companies, we reduce costs and installation time by utilizing our proprietary foam concrete ConFoam™ for multiple applications, including annular grout and void space backfill. ConFoam™ is a cement-based slurry with a foaming agent that is highly flowable and doesn’t settle. It’s often referred to as “liquid backfill,” because it flows smoothly and completely fills voids.

A Customizable Solution

Conco adjusts the density of ConFoam™ for each application for optimal results. When used for annual grout backfill, ConFoam™ is produced at a lighter density to prevent the carrier pipe from floating. When produced as a void space backfill, the density is customized for compatibility with surrounding structures and soil conditions.

ConFoam™ also has low viscosity, which allows it to be pumped across thousands of feet to locations that otherwise couldn’t be reached by traditional backfill. Traditional backfill might require an expansion of the excavation site just to make room for equipment and workers, while ConFoam™ requires less accommodation. Workers also don’t need to be in excavation sites to install ConFoam™. They can simply use hundreds of feet of hose to pump ConFoam™ into out-of-reach voids that’d otherwise be problematic for traditional backfill.

Fast and Effective Emergency Relief

Conco produces our proprietary ConFoam™ to be quickly mobilized for emergency repairs. It requires less equipment and labor than traditional concrete, making it an ideal choice for timely responses. Workers can begin filling voids within an hour of arrival. ConFoam™ also reaches 100% consolidation sooner than traditional concrete due to its self-leveling and self-compacting characteristics. Unlike traditional backfill, ConFoam™ doesn’t settle, shrink, or have unexpected strength gain.

Superior Alternative to Other Backfill Methods

ConFoam™ doesn’t have the drawbacks of other backfill methods. Backfilling with layers of aggregate base material requires intensive labor, and difficult compaction, and leaves you with a backfill that has a tendency to settle and be washed away. Another backfill material, which is concrete-based and called controlled density fill (CDF), doesn’t flow as well as ConFoam™ and can be difficult to excavate because it gains strength over time.

There are many other benefits to using ConFoam™ as annular grout and void space backfill, not limited to:

• Proven Expertise – Conco teams are experienced at producing and placing ConFoam™.
• ConFoam™ replaces the need for Expanded Polystyrene Geofoam Blocks 
• Self-Compaction – ConFoam™ doesn’t use mechanical compaction or compaction testing.
• Cost-Effective – ConFoam™ reduces costs associated with transportation, equipment, and labor when compared to traditional backfill.
• No Waste – ConFoam™ is produced on-site as it is needed. Production stops once the project is filled, reducing the carbon footprint.

ConFoam™ Safely and Quickly Fills Pipes

ConFoam™ is a dependable abandonment backfill because it self-compacts, doesn’t settle or shrink, and can be pumped across thousands of feet into pipes that are difficult to reach with traditional equipment. ConFoam™ flows at <60 psi at 7,500+ feet, a lower pressure than that of typical sand slurry mixes, and can fill entire pipelines through minimal access points. Its equipment is also quickly mobilized and can finish pipe abandonment jobs within a single day. When the pipes decay, the rigid structure of ConFoam™ will significantly reduce the risk of underground voids.

By customizing the ConFoam™ mixture for various densities, Conco can utilize it for a multitude of projects, including pipelines of all types and sizes. It can backfill everything from abandoned sewer lines to water lines, fuel tanks, septic tanks, culverts, and more. ConFoam™ is also a quicker and more cost-effective choice than removing decommissioned pipelines, which disrupts communities and causes traffic congestion.

Additional benefits of using ConFoam™ for pipe abandonment backfill are:

• Self-Compaction – ConFoam™ doesn’t need mechanical compaction or compaction testing.
• Customizable – ConFoam™ can be produced to match the weight of the soil surrounding the pipeline.
• Lightweight – ConFoam™ can be produced to weigh less than compacted base materials or native soils.
• Quicker and Safer Placement – ConFoam™ installation uses less equipment and manpower than traditional backfill methods. Workers don’t need to be in the excavation site, reducing risk of injury.
• Low pressure delivery – pump long distances without having to put excessive pressure on the pipe itself.
