The LFC100H/SF foam concrete grouting equipment converts truck-delivered premixed mortar into foamed concrete directly on site. It supports void filling, low-strength backfilling, tunnel construction and specified onshore and offshore grouting applications.

Production begins with 50:50 premixed mortar being discharged from a concrete mixer truck into the unit’s built-in receiving hopper. A mechanical agitator keeps the mortar mixed before it enters the delivery stream, where preformed foam is injected inline to produce the finished foamed concrete.

The system is assembled on a heavy-duty steel skid frame with integrated jacking legs and wheels for positioning and movement around the worksite. Its compact layout fits within a standard 20-foot container, simplifying transport between projects and storage when not in use.

1. Confined-Space Backfilling

Produces flowable fill for narrow excavations and spaces around utilities where access for conventional compaction equipment is limited.

2. Tunnel and Underground Works

Supplies foamed concrete for specified cavities and backfill zones associated with tunnel construction and underground infrastructure.

3. Redundant Infrastructure Filling

Supports the filling of decommissioned pipes, disused chambers and other enclosed voids through planned access points.

4. Low-Strength Civil Engineering Fill

Prepares lightweight backfill with density and strength tailored to project specifications, including applications with defined future excavation requirements.

5. Onshore and Offshore Grouting Projects

Provides on-site foamed concrete production for specified grouting and filling operations, with material formulation and placement arrangements matched to the project conditions.

1. Direct Feeding from Mixer Trucks

The integrated receiving hopper accepts premixed mortar delivered by concrete mixer trucks. A mechanical agitator keeps the incoming material mixed before processing.

2. Foam Addition within the Pipeline

 An inline injection system introduces preformed foam into the mortar stream, producing foamed concrete without requiring the unit to prepare the base mortar on site.

3. Flexible Material Properties

Adjustments to foam dosage and mortar formulation allow production to suit different specified densities and strength requirements.

4. Siemens Variable-Frequency Drive

The electrically driven system uses a Siemens frequency inverter to adjust operating speed according to production needs.

5. Centralized Process Monitoring

Siemens controls bring production monitoring and operating adjustments together, helping operators manage the foam concrete production process.

6. Flowable Backfill without Vibration

Properly proportioned mixes spread into designated spaces and level during placement, eliminating the need for mechanical vibration compaction.

7. Skid Frame with Positioning Supports

A heavy-duty steel frame incorporates jacking legs and wheels to assist equipment positioning and relocation on site.

8. Compact Transport Dimensions

The complete unit fits inside a standard 20-foot container, making transportation and storage convenient between projects.
