Rampless Container

Our rampless container is a great solution when you've only got concrete mixer trucks to service or when space is especially tight. This container offers slightly more capacity than our ramped container. Be aware that this container is not generally suitable for jobs where concrete pump trucks are in operation. Most of our customers maintain a couple rampless containers for specialty situations where space is at a premium.

Porta-Vac is designed for the super-duty concrete washout application from the ground up. It fits on our roll-off truck next to our washout container - allowing a single truck to do double duty vacuuming and hauling containers.

Environmental and Human Health Impacts

Concrete washout water (or washwater) is a slurry containing toxic metals. It’s also caustic and corrosive, having a pH near 12. In comparison, Drano liquid drain cleaner has a pH of 13.5. Caustic washwater can harm fish gills and eyes and interfere with reproduction. The safe pH ranges for aquatic life habitats are 6.5 – 9 for freshwater and 6.5 – 8.5 for saltwater.

Washout Containers

Different types of washout containers are available for collecting, retaining, and recycling the washwater and solids from washing down mixed truck chutes and pump truck hoppers at construction sites.

Uses of Recycled Materials
