AggReFlo

A construction material which is flowable during installation and which may be produced from nearly any kind of excavated material.

AggReFlo may be used in most backfill situations, such as filling utility or service trenches, backfilling excavations on construction sites, filling voids, tunnels and galleries and use on sites requiring large quantities of material. AggReFlo also offers the possibility of changing its properties to suit the individual application requirements.

Properties

• Flowable
• Pumpable
• Self-compacting
• May be laid under water
• No settlement
• No crowning
• Use of most types of soil and recycled aggregate possible
• Can be topped quickly
• Can be excavated again easily
• Gas permeable
• Mitigates vibration
• Non-toxic, non-hazardous
• Easy to produce and handle

Advantages

• Quicker completion with lower labour requirements
• Reduction of volumes handled
• Lower space requirements
• Improved operator safety
• No compaction in wet trenches
• Quality management gives defined properties
• Allows gas leaks to be detected
• Good bedding properties, leading to long-lasting service networks
• Homogeneous ground reinstatement avoids discontinuities
• No compaction damage – may be used with all types of pipe materials
