The hold down spacer system has been developed to provide a means of preventing conduits from floating as the flowable fill is being poured into the trench.
Using Acro props and removable adjustable poles – the Acro props straddle the trench supporting poles which provide downward pressure on the bank of conduits.
The system avoids the use of stakes or heavy concrete blocks and the only item left in the trench is a small plastic fitting.
