4' x 4' construction washout portable fiberboard system

Revolutionizing the portable construction washout industry is the 4'x4’ washout from Outpak. It is designed for easy setup while still allowing for at least 10 concrete washouts. Keep your construction site eco-friendly and use this unit to washout concrete, stucco, mortar, paint, drywall mud, and more.

Setup and disposal is easy

The unit ships flat so it is portable and easy to take anywhere, when you are ready to use simply unfold the water treated Kraft fiberboard on a pallet and line with the included 6mL bag. When the washout is full let it dry till it becomes solid and then the entire washout can be disposed of in any trash location, if you need the material to dry quicker use the optionally purchased Outpak Slurry Solution Solidifier to harden the material quickly.

Be in EPA compliance

EPA fines can be staggering at your job site if you are not properly washing out your construction material, be in compliance with the easy to use and set up Outpak 4' x 4' washout system.
