Construction cores, also known as construction tubes, are a type of spiral wound cardboard (wood pulp fiber) tube used primarily in construction. Construction cores are also useful in small commercial and DIY home improvement applications. In construction, they assist in forming load bearing concrete columns. The load bearing columns they help make are used in all sorts of applications, including foundationing (concrete piles) and highway support.
Construction cores act as a mold into which workers can pour liquid concrete. They are strong and stable enough to hold and pressurize the liquid concrete. Once manufacturers have poured the concrete inside the construction core, the workers let it sit until the concrete cures. Then, they can either remove the cardboard core or leave it on. Read More…
