Frost Sleeve

Techno Metal Post’s proprietary green sleeve guarantees frost protection.

The ‘frost protection sleeve’ that allows us to guarantee that our piers will not move or heave due to freezing winter soils. One of the major challenges any foundation system must face is ground movement due to seasonal freezing and thawing. Our frost protection sleeve acts as a slip sheet; sliding up and down the pier with any ground movement while allowing the pier itself to remain stable.

The high-density polyethylene is designed and manufactured by Techno Metal Post in a variety of sizes to complement each of our different pier sizes. The sleeve is installed while the pier is screwed into the soil.
