Weld Co. School District RE-1 Valley High School – New Greenhouse

The initial timing of the project was a challenge due to pouring concrete during the coldest and snowiest week of 2021! Due to the frozen temperatures, we utilized ground thawers onsite to thaw the ground which helped the backfill process. When the weather warmed up, we reconditioned the dirt as needed to achieve proper compaction and made sure our tests come back positive. We have certain soil density tests we must pass before we pour the concrete slab, so the warmer weather during the following months was relief. Having the compaction right in the soil helps prevent the slab from settling or heaving over time.
