General FAQs

Can this product be safely used in damp soil conditions?

Postloc has been used successfully in damp soil conditions. We recommend that standing water be evacuated from hole prior to setting a post.

Can this product be safely used in cold weather?

Yes. Outside temperatures do not affect final product performance. Freeze-thaw cycles have no performance effect on cured Postloc.

Can Foam backfill be used to anchoring applications?

Yes it can and probably should. Foam sticks to everything where concrete or tamped dirt anchoring does not have inherent adhesive properties. Adhesive properties lend to improved anchoring. Foam expands and creates a fish hook type effect by filling all the fissures in the ground and pole. Tamped dirt and concrete do not have these foam enhanced properties that lend toward improved anchoring.

Do the bonding properties of Postloc change depending upon the post material types (e.g. wood, metal, vinyl, etc.)?

Yes. Adhesion strength varies with different material types. However, Postloc has superior bonding to all post materials compared to other backfill products, like concrete.

Does humidity affect curing time? If so, how?

Not significantly. As humid as it can be, you can use the product. Just don’t use in the rain.

Does Postloc help preserve posts?

Yes. Postloc encapsulates posts preventing a shield against moisture and helps preserve post materials from decay and rust. Postloc forms a bond directly to posts, eliminating long-term deterioration effects.

Is the curing time related to outdoor temperature?

Yes. In most cases the time difference is insignificant. Colder temperatures can slow curing time.

What are the safe storage requirements and acceptable storage temperature minimum/maximum ranges for Postloc?

Closed, unopened containers of Postloc should be stored between 50°F-95°F (10°C-35°C). Detailed storage requirements are listed on each Postloc box.

We do not have a definitive answer, but know Postloc will outlast us.

What is the normal shelf life of this product?

When stored under recommended conditions, 24 months.

What is the setting/curing time until the product is 100% cured?

15 minutes. Cooler component and/or environmental temperatures can extend curing time.


Does Postloc contribute to Global Warming?

No. Postloc does not contribute to global warming, ozone depletion or smog production.

Is Postloc harmful to soil and ground?

No. Cured Postloc product is inert and does not pose a threat. Quite the opposite, Postloc provides protection. BMK backfill products have been 3rd Party Tested and proven to mitigate and contain harmful effects of historical post preserving materials like creosote.
