In Quebec's formwork, construction, and heavy transport industries, keeping a vehicle fleet clean and well-maintained isn't just about appearance—it is a major factor in efficiency and profitability. Built-up concrete, mud, grease, and road salt accelerate parts wear, hide damage during SAAQ inspections, and waste valuable time for field crews.
This blog post highlights the turnkey project completed by Multi PSI for the team at Coffrage Quatre Saisons. We cover the real challenges of heavy-truck washing, equipment selection (pressure, flow rate, 575 V power, hot water system), and the Canadian debut of our brand-new MHP high-pressure foam system. A true benchmark for fleet managers and contractors looking to optimize their wash bay.

Regular maintenance of heavy vehicles requires high-performance equipment suited to the harsh conditions of Quebec job sites. The design of Coffrage Quatre Saisons' brand-new wash bay reflects our commitment to providing rugged, durable equipment. Custom-built by Multi PSI specialists, this turnkey installation meets the daily cleaning demands of trucks, cement mixers, and formwork equipment.
By combining high water pressure, a powerful heating system, and effective soap distribution, this wash bay completely redefines heavy vehicle cleaning. Here is a full breakdown of the technical components that make this project an industry reference.
Renowned across Quebec for the quality of its residential, commercial, and civil formwork, Coffrage Quatre Saisons operates a large fleet of transport trucks, backhoes, cranes, and tool vehicles. Every day, these vehicles navigate mud, gravel, cement dust, and concrete residue, demanding ongoing maintenance to prevent corrosion and premature wear.
Cleaning construction trucks in Quebec comes with unique operational constraints:
To overcome these exact issues, management turned to Multi PSI to design Coffrage Quatre Saisons' wash bay.
The core component of the wash bay is the MPC4030-HE4-63 stationary high-pressure washer. This industrial unit delivers 3000 PSI at a constant 4 GPM flow rate—the ideal balance for removing dirt and concrete crust without damaging paint or electrical components.
Cold water simply spreads grease and job-site oils around. That is why Coffrage Quatre Saisons' wash bay relies on a 48 kW industrial electric water heater. This system raises water temperature rapidly to dissolve greasy residue instantly, cutting cleaning time in half compared to cold water.
To power the pumping and heating equipment without overloading the network, the entire system runs on a 575-volt three-phase power supply—the Quebec industrial standard for maximum electrical stability and reliable startups.
For workplace ergonomics, Multi PSI installed overhead tracks mounted to the ceiling on each side of the bay. Each track carries two separate lines:
No more hoses lying around on the floor. In addition to preventing hose damage from vehicle tires, overhead tracks keep the ground clear. Operators can walk around a semi-trailer without hauling heavy hoses or tripping.
This project at Coffrage Quatre Saisons is a proud milestone for our team: they were the first client to deploy our new MHP high-pressure foam system. Unlike low-pressure foam cannons, the MHP system projects rich foam at high velocity. The foam clings to vertical surfaces and undercarriages, letting the detergent break down grime without requiring hours of manual scrubbing.
The system draws biodegradable MPSI-5011 industrial detergent directly from a drum. Developed by Multi PSI for Quebec's heavy sector demands, this soap strips soot, oil, and road film while remaining eco-friendly and safe for oil separators.
Here is a concrete overview of the gains achieved thanks to the new installation:

A turnkey system integrates the high-pressure washer, water heater, overhead tracks, and soap system into one setup. This cuts washing time by over 60% while increasing workplace safety and extending vehicle service life.
A 48 kW heater delivers consistent hot water that melts grease, oils, and cement buildup effortlessly, drastically speeding up cleaning while reducing chemical use.
The MHP system projects dense foam at high pressure, instantly clinging to truck surfaces. The chemical penetrates deep to break down grime without intensive manual scrubbing.
This stationary model delivers 3000 PSI at 4 GPM. Designed for hot water application, it runs on a 575-volt three-phase power supply.
Overhead tracks keep hoses off the ground to prevent tire damage and tripping hazards. The dual line allows operators to switch instantly between high-pressure rinsing and MHP foam application.
Yes, MPSI-5011 industrial detergent is a 100% biodegradable formula. It provides strong degreasing power while adhering to Quebec environmental standards.
A 575-volt three-phase industrial connection with a 60-amp circuit is recommended to reliably power the pressure pump and 48 kW water heater.
Combining hot water, MHP foam, and overhead tracks reduces full vehicle wash times to just 20 to 30 minutes, down from over an hour.
