FAQs
What Are Pour/Delay Strips?
A pour strip (or delay strip, closure strip, pour back) is a temporary gap—typically 3 to 6 feet wide—left in a concrete slab during construction to allow for shrinkage and minimize cracking.
Why Are Pour Strips Necessary?
Pour strips are used to mitigate the restraint-to-shortening that occurs as concrete cures. By leaving a pour strip, the surrounding slab can shrink without impact from restraint forces.
Why Are Pour Strips Left Open So Long?
Concrete shrinkage happens gradually – most shrinkage happens within the first year after the concrete is poured. Leaving the pour strip open longer allows the most shrinkage to occur and will deliver higher quality concrete.
Why Are Pour Strips So Problematic?
Because they increase costs, delay schedules, inhibit workflow, and create safety hazards.
What Are The Replacement Options For Pour Strips?
PS=Ø is the only system that is equivalent to a traditional pour strip. The PS=Ø system allows concrete to shrink naturally without cracking, while also eliminating the construction delays caused by traditional pour strips. Delivering a clean, continuous slab without obstructing the work of other trades.
How Do I Start Using PS=Ø On My Project?
Getting started is easy - Our team of experts are ready to help you implement our system into your project, providing guidance every step of the way.
