Fast Fix Flowable Fill Base, or 4FB, is a fast-setting, self-leveling base material that can be placed with minimal effort, requiring no compaction or tamping. With properties that can be designed to exceed flex base and cement-treated base, Fast Fix Flowable Fill Base helps you finish your project ahead of traditional schedules and at lower costs.
For street repairs, Fast Fix Flowable Fill Base can be poured in place of compacted materials or lean concrete. When time is at a premium and a street needs to be opened quickly, Fast Fix Flowable Fill Base can be capped with concrete pavement or asphalt pavement in as little as one hour. In areas where final grade will be overlaid at a later time, higher-strength 4FBs can act as a temporary patch without the need for steel plates.
Fast Fix Flowable Fill Base is an excellent choice for base material under concrete pavers as well. Its ease of placement reduces labor costs and equipment costs, and eliminates the need for a stockpile of unsightly base material at the job site. 4FB is able to bridge over sub-grades due to its slab-like characteristics. This reduces the amount of base material necessary, further reducing placement costs.
No Competition from Crushed Stone Base.
4FB is:
- Easy to install
- Rapid setting
- Strong and durable
With Fast Fix Flowable Fill Base, contractors can complete their projects more quickly and with less equipment and lower labor costs than when using traditional flex base or cement-treated base. Fast Fix Flowable Fill Base is an ideal product for time-sensitive projects for which meeting a deadline is not an option.
