What is ShieldFoam PLF?

ShieldFoam PLF (Pole Lock Foundation) is an industry tested and approved structural foundation foam for use with poles and posts. It is a closed-cell polyurethane foam that provides an effective and stress-free replacement for the use of concrete as a backfill. With fast setting properties (<15 minutes to set before conductor stringing or fence tensioning), minimal time, transport, and manual labour is required when compared to concrete or other backfill types. 

Our foundation foam provides exceptional performance over both short and long-term projects. Based on testing in Australia, ShieldFoam gives exceptional short-term capacity, even when filling half the hole depth (recommended for long-term pole durability). In fact, it delivers better results than 3 months of consolidated tamped backfill. 

ShieldFoam has been designed to not to hold moisture around the pole or post at the critical groundline regions, while allowing for regular inspections techniques to be performed at ease.  

ShieldFoam eliminates issues with concrete compaction, soil tamping, cracks and cold joints causing hidden corrosion issues, transport times for concrete to remote sites, and reduces manual labour.

Specifications

Nominate ShieldFoam PLF backfill to a maximum of 400mm below ground line (recommended) and a minimum of 50% of the embedment depth of the pole/post. Refer to the TDS for useful tables that give the amount required for different hole and pole size combinations. ShieldFoam must be stored, mixed and applied in accordance with the manufacturers instructions.
