When using a vacuum excavator, you want to work quickly. But you can only work as quickly as you can dump your spoils once the day is over. And when working in clay soil, material can get stuck on the insides of the tank and hose, making it a challenge to fully empty your machine.
That’s where Vermeer vacuum excavators and VacMax Plus from Right Turn Supply come into play.
Between the dirt coating technology of VacMax Plus and the design features of Vermeer vacuum excavation trucks, you can dispose of spoils efficiently and move on to the next job with a cleaner truck.
Improve vacuum excavator dumping efficiency with VacMax Plus
VacMax Plus is a solution designed specifically to maximize efficiency for your vacuum excavator when potholing and dumping.
It goes in the clean water tank on your vac and coats the inside of the spoil tank and suction tubes during pothole operations, while also coating the soil coming in. This lubricates the equipment and material so that the clay can slide through the tubes and tank more efficiently.
“At the end of the day it just makes you more efficient and keeps your equipment maintained a little bit better,” said Christian Rich, regional manager at Right Turn Supply.
Getting more material out of your hydrovac during the dump cycle can help reduce cleanup time and simplify maintenance.
“If you can dump cleaner, it saves time,” said TJ Steele, product manager for Vermeer MV Solutions.
How VacMax Plus works with Vermeer vacuum excavators
The design of Vermeer vacuum excavators enables operator-friendly integration of the water-soluble solution and efficient spoil dumping.
The patent pending detergent injection system on Vermeer vacuum excavation trucks allows you to fill it with detergents like VacMax Plus. As you’re digging, VacMax Plus is injected through the digging wand and is mixed in to coat the soil, suction tubes and tank as you suck up into the spoil tank.
“On our control system, you can cut the detergent pump on or off,” Steele said. “With that, there’s different dosing rates, so you can dose based on percentage.”
Controlling the dose means you can make the most of the solution in the soil where it can be most impactful. Right Turn Supply recommends one jug of VacMax Plus for every 500 gal (1892.71 l) of fresh water.

How Vermeer vac truck features improve dumping efficiency
Beyond additives, built-in features on your vacuum excavator also play a key role in efficient dumps and cleanouts.
- Spoil tank vibrator (optional): Available on VXT vacuum trucks, this feature helps break loose materials that may be stuck in crevices.
- Reverse pressure system: On the VXT400 vacuum excavator and VXT500 vacuum excavator, operators can pressurize the tank to push debris and mud out the rear valve rather than opening the rear door.
- Reduced jobsite equipment: Reverse pressure can reduce the need to bring a trash pump to these jobsites.
Work within vac spoil disposal regulations without losing efficiency
When it comes to dumping spoils, regulations don’t just impact where you take material — they can also influence what you put into your system in the first place.
Hydrovac spoils are often evaluated for contaminants, and disposal facilities may have strict requirements based on what’s in the load.
According to Hydrovac News, waste handling is shaped by federal guidance like the EPA’s Resource Conservation and Recovery Act (RCRA), along with state and local rules that can vary by jobsite.
That means every additive you use can factor into whether material is accepted at a disposal site.
VacMax Plus was designed with that reality in mind.
Key environmental considerations built into VacMax Plus:
- Prop 65-compliant formulation for stricter regulatory regions
- Biodegradable composition to support responsible disposal
- No sheen or residue left on material
You shouldn’t have to slow down to stay compliant. With VacMax Plus, you don’t.
From coating to solidifying: a complete solution for better spoil dumping results
The second half of the Right Turn Supply vacuum excavator system is Liquid EnviroDry. While VacMax Plus is put in before you start digging to coat the material, spoil tank and suction tubes, Liquid EnviroDry is added during the operation to help solidify the spoils.
“It rapidly converts liquids into solids, expands disposal and haul-off options, maximizes uptime and lowers cycle costs for vacuum excavation,” Rich said.
Its first-of-its-kind solidification technology allows for application through the vacuum tank, pumps or sprayers, giving you flexibility for maximized performance from start to finish.
Together, VacMax Plus and Liquid EnviroDry work to make each dump of your spoil tank more efficient, so you can get to your next jobsite.
