The Complete Solution: Why Evans Is the One Call You Need for Wash Systems That Work

Tired of “Turnkey” Promises That Turn Into Headaches?

“Turnkey” gets tossed around like it’s a guarantee. But more often than not, it’s just lip service. When you decide it’s finally time to invest in a permanent wash bay, you don’t want to become a part-time project manager just to get a functioning system.

And yet, that’s exactly what happens. A so-called “turnkey” provider sends you a set of blueprints and a sky-high invoice, leaving you to track down permits and manage contractors. And then, surprise! The concrete guy isn’t even licensed. 

We’ve heard it all before. So we built something better: a complete solution.

Don’t Make 5 Calls. Just Call Evans. 

At Evans Equipment & Environmental, we don’t just say turnkey. We deliver it. 

You make one call, and you get a partner who can handle everything. From concept to completion, we design, build, and maintain custom wash bays that check all your boxes. We design to spec so that you can precisely optimize your workflow, maximize your uptime, and provide sustainable water treatment solutions that keep you compliant, efficient, and stress-free. When you work with Evans, you’re getting more than the equipment you need; you’re getting a partner you want – one who will get it all done. 

• Design that fits your needs and your site
• Build services with our own licensed in-house construction crews

We take care of every phase, so you don’t have to.

Why Build a Semi-Custom Wash Bay with Evans 

We’re the only national wash water treatment company that offers truly integrated wash bay systems with a single point of contact. Our high-performance wash solutions are designed to:

• Keep you compliant
• Reduce downtime
• Control water use and environmental impact
• Eliminate typical construction chaos

Our semi-custom approach means you get a tailored system without starting from scratch. From equipment selection to system installation, we guarantee that your wash rack will meet regulatory standards, enhance operational efficiency, and stay within budget without cutting corners. How can we promise that? Because we’re not outsourcing the build to a bunch of subs. We bring our team with the right tools and the proven expertise to get it done.

How We Build Wash Bays to Last  

If you want a job done right, you have to do it yourself. 

From the Gulf South to the Pacific Northwest, Evans crews are on the ground, overseeing construction themselves, not just handing you a PDF and wishing you luck. When it comes to quality wash bay construction, we don’t leave things to chance (or unreliable subcontractors). Every project starts with a thorough site survey. Armed with the necessary information to ensure precision, our dedicated project foremen and superintendents oversee every stage of construction. They plan, lead, and deliver results with structural reinforcements and concrete mixes designed to withstand the impact of water, chemicals, and heavy equipment.

Not All Concrete is Created Equal

Wash bays face harsh conditions and intense wear from water, chemicals, oils, and bacteria. So a basic concrete mix poured by a random contractor isn’t going to cut it. At Evans, we entrench microbial additives into our concrete blends to protect the structure of your wash bay from damaging bacteria and oils. This extends the life of the concrete, making it more cost-effective and environmentally sustainable. So, we don’t just pour, we protect with: 

• Waterproofing
• Antimicrobial additives
• Fiber mesh reinforcement 
• Proper concrete sealing 

A Process to Build Your Trust On 

Here’s what “turnkey” actually looks like when Evans handles your wash bay:

1. Consultation & Site Survey

We start by understanding your business goals, water use, equipment load, and compliance requirements etc. Then we assess your space and identify the best way forward.

2. Strategic Design

Need a retrofit? Building new? We design a layout that works with your space, your team, and your environmental regulations and industry standards. And, we don’t bloat the budget. 

3. Precision Fabrication

Our in-house team uses SolidWorks 3D modeling to generate detailed drawings and custom component designs. Typically, fabrication is usually completed in about a month.

4. In-House Construction

Here is where we separate from the pack. Other companies say they’re turnkey, but they don’t do the build themselves. We’ve got our own, in-house construction crew who handles the jobs:

• Permitting
• Site prep
• Plumbing and drainage
• Concrete pour

5. Maintenance

After we install your custom wash bay, we train your team to operate and care for your system and offer quarterly service visits to keep everything running smoothly. You’ll also get 24/7 technical support from our experts. Just one call away.

Need More Out of Your Wash Bay?

Boost the functionality and performance of your custom wash bay with special additions.

1. Improve Overspray Containment with Splash Walls

While the decision to add splash walls to your custom wash bay is unique to your operational needs, there’s no denying the benefits. Splash walls keep the surrounding areas and machines clean and dry. Plus, they reduce contamination risk and enhance operational safety by controlling overspray.

2. Transform Your Space with Aprons  

A well-designed apron creates a smooth, stable transition between surfaces, making it safer and easier for vehicles and crews to move in and out. It also boosts curb appeal, enhances accessibility, and protects your foundation from long-term wear and tear. It’s a small upgrade that delivers big value.

3. Fortify Safety with Handrails & Bollards

These simple additions significantly boost safety and security by helping prevent falls, guiding traffic, and protecting both people and equipment from accidental damage. They also help you stay compliant while safeguarding your assets and investments with minimal maintenance and maximum peace of mind. It’s a lot of bang for your buck.
