BMK Polecrete® lets you set and secure poles and posts in as little as 15 minutes.
BMK Polecrete Stabilizer Hydro is designed for use in high moisture situations. BMK Polecrete Stabilizer Hydro is a two part foam designed to react in the presence of water without leading to adverse reductions in product performance. In the presence of water, other foams typically produce more foam than dry conditions, which yields a product with lower density, lower strength backfill. BMK took the challenge to solve this issue. BMK's scientists took the standard Polecrete formula and made several subtle changes to build Hydro Polecrete, a product made for higher-moisture soils. It is denser than regular Polecrete: 5.0 pounds per cubic foot (PCF) as opposed to 4.0 in our regular formula. BMK also greatly improved the flexural strength of Hydro Polecrete, giving it roughly double the strength of original Polecrete. This allows it to stay firm and solid even under intense pressure from soil that is heavy and sodden from recent storms.
BMK has a void calculator to calculate the amount of Polecrete needed for a specific hole and pole location:
It is important to remember that all foam backfill products are lighter unit weight than water and all foams react on top of water in a pole hole. There is no foam that pushes the water out of a wet hole when dumped directly on top of the water. A wet pole hole may still have a firm foundation after using foam, but that is due to the foam pressure against the soil above the water. The water in the hole is not displaced without efforts to “bag the pole”, a process that BMK helped perfect with a coastal utility (Entergy, Louisiana) that experiences water in their pole holes very often. When water in the hole exceeds a certain level, utilities must decide on when to require bagging a pole. Typically, BMK sees utilities allow up to 10% of the pole hole to be full of water without requiring bagging the pole.
Example: 6’ deep hole, allowable water equals 6*12*0.10 = 7.2”
This allows the bottom portion of the pole to be either “wet” with no soil around the pole, or dry if the water table drops at the pole location over time
