The LFC100H/SF CLC foam concrete backfill machine provides an on-site production solution for contractors working with truck-delivered premixed mortar. It combines mortar receiving, mechanical agitation and inline foam injection in a compact skid-mounted unit, supporting lightweight backfill and grouting projects without requiring the equipment to prepare base mortar from raw materials.

During operation, mortar enters the integrated receiving hopper directly from a concrete mixer truck. The hopper agitator keeps the material mixed before preformed foam is introduced into the flowing mortar inside the pipeline. By coordinating the mortar formulation and foam dosage, the system produces cellular lightweight concrete to meet specified density and strength requirements.

This foam concrete grouting equipment is suited to projects where material flowability, reduced fill weight and access to confined spaces are important. Its compact construction also makes transportation and positioning convenient for contractors moving between sites.

Utility Trenches and Restricted Excavations
Produces low-strength backfill for designated areas around utility installations and within narrow excavations. Its flowable consistency allows placement where conventional compaction equipment has limited access.

Tunnel Backfill and Underground Grouting
Supplies foamed concrete for specified tunnel cavities and underground filling zones. Material density, delivery arrangements and placement pressure are selected to suit the surrounding structure.

Abandoned Pipelines and Redundant Chambers
Supports the filling of decommissioned pipes, disused chambers and similar enclosed spaces through planned access points. Filling sequences and venting arrangements help manage placement within the available void.

Lightweight Civil Engineering Fill
Produces cellular concrete for projects requiring lower fill weight than conventional dense materials. The mix can be designed around the required balance of density, flowability and strength.

Onshore and Offshore Filling Works
Provides foam concrete production for specified land-based and marine grouting applications, with material suitability and containment arrangements determined by the project design.

Designed Around Premixed Mortar Supply
Direct truck discharge into the receiving hopper connects delivered mortar with on-site foam concrete production, simplifying material handling.
Integrated Mechanical Agitation
The hopper agitator maintains the incoming mortar in a mixed condition before it passes into the production stream.
Inline Foam Introduction
Preformed foam is added within the pipeline, incorporating the foaming stage into the material flow without a separate full-batch foam concrete mixing tank.
Adaptable Backfill Properties
Mortar composition and foam addition can be adjusted to suit different density and strength specifications. Final material properties depend on the approved mix design and production conditions.
Siemens Drive and Process Controls
An electric drive with a Siemens frequency inverter provides speed adjustment, while the Siemens control system enables production monitoring and operating control.
Placement without Vibration Compaction
Properly proportioned foamed concrete flows into prepared spaces and levels during placement, supporting filling work where mechanical compaction is impractical.
Skid-Mounted Construction
A heavy-duty steel frame, integrated jacking legs and wheels assist site positioning and relocation. The complete unit fits inside a standard 20-foot container for transport and storage.
