Your Patio Should Still Look Perfect in 10 Years.
Most hardscape fails because of what you can't see — the base. Harkins Unique Landscapes builds patios, retaining walls, and walkways the right way, using proper base preparation and materials suited to Illinois freeze-thaw cycles.
That Patio Looked Great — Until the Second Winter.
Hardscape failure isn't bad luck. It's bad base prep. Across Iroquois and Kankakee counties, Jon has been called in to fix patios, retaining walls, and walkways that failed within 2–3 years of installation — not because the surface material was wrong, but because what's underneath it was done cheaply.
Illinois soil expands and contracts with freezing. Without a properly compacted base and the right drainage, your hardscape will shift, crack, and heave — no matter how good the stone looks on top.
"We rebuilt a retaining wall someone else had installed two years prior. The materials were fine — the base was 2 inches of gravel instead of 8. That's the whole difference."
— Jon Harkins, Owner & InstallerHardscape Installation in Gilman IL — Done the Way It Should Be
Jon Harkins has been installing hardscape across Iroquois and Kankakee counties since 2009. That's 16 years of working with central Illinois soil — the clay-heavy, moisture-retaining ground that makes base preparation non-negotiable if your hardscape is going to last.
When you call Jon, you're not getting a crew he's supervising from a distance. He's on-site. He's the one prepping the base, setting the slope, integrating drainage, and making the judgment calls that determine whether your patio holds up for 5 years or 25.
From First Call to Finished Patio — What to Expect
No guesswork, no surprises. Here's how every hardscape installation project unfolds with Harkins Unique Landscapes.
Free On-Site Consultation
Jon visits your property, walks the space with you, and discusses your goals. He'll assess the soil, drainage, and grade — and tell you honestly what will work and what might cause problems. No ballpark numbers over the phone: every quote is based on actually seeing the site.
Clear Quote, No Surprises
You receive a detailed written quote that covers materials, labor, timeline, and exactly what's included. The quote is the price — not an opening bid. If something changes during the project that affects cost, Jon discusses it with you before any additional work is done.
Excavation & Base Preparation
This is where most hardscape installations either succeed or fail. Jon excavates to the correct depth for your soil type and project size, installs road gravel base material, and compacts in lifts — creating the stable foundation that makes the difference between a 3-year patio and a 25-year patio.
Surface Installation
With the base prepared correctly, the surface material goes in cleanly and precisely — set to proper grade for drainage, with consistent joints and finished edges. This is also where the visual design decisions come to life: pattern, material, edge treatment, and borders.
Cleanup & Walkthrough
Site is cleaned up — excess material removed, disturbed areas raked and seeded. Jon walks the finished project with you, explains any maintenance considerations, and makes sure you're satisfied before calling it done.
What happens if we find unexpected site conditions? Jon stops, shows you exactly what was found, explains the options, and lets you decide before any additional work begins. Your quote price doesn't change without your approval.

How much does hardscape installation cost in Iroquois or Kankakee County?
Hardscape installation pricing varies significantly based on the type of project (patio, wall, walkway), size, material selection, site conditions, and how much base preparation the soil requires. Jon doesn't give ballpark prices over the phone — because a number without a site visit isn't an accurate quote, it's a guess that could mislead you. Contact us for a free on-site consultation and you'll receive a detailed written quote based on your actual project.
Why does hardscape fail in Illinois, and how do you prevent it?
The primary cause of hardscape failure in central Illinois is inadequate base preparation. Illinois soil — particularly the clay-heavy ground in Iroquois County — expands and contracts significantly with freeze-thaw cycles. Without a deep, properly compacted gravel base (typically 6–12" depending on project and soil type) and integrated drainage, surface materials shift, crack, and heave over time. Jon's installations start with base-first engineering: the right depth, the right material, and drainage factored in from the design stage.
Your quote is higher than another contractor I received. Why?
There are legitimate reasons quotes vary: different material choices, different project scope, or different standards for base preparation. When comparing quotes, ask the other contractor what base depth they're planning, what compaction process they use, and whether drainage is included. If their quote excludes proper base prep, you're not comparing the same job — you're comparing a project that will last vs. one that may need replacement in 3–5 years. Jon is happy to explain every line in his quote so you understand exactly what you're getting.
How long does a hardscape installation project take?
Project timelines depend on size and complexity. A simple walkway might be completed in 1–2 days. A full patio installation typically runs 3–5 days including base prep, installation, and finishing. Retaining wall projects vary based on size and height. Jon provides a specific timeline with every quote, and if weather or site conditions affect the schedule, he communicates proactively — not after you've been waiting.
Do you handle both the hardscape design and installation?
Yes. Jon works with you from concept through completion — helping you choose materials, plan the layout, integrate with your existing landscape design, and then handling the full installation. If you already have a design concept in mind, he can work from that too. The advantage of having one person handle both design and installation is that every decision is made with the installation process in mind — no surprises when we get to the ground.
Can you combine hardscape installation with landscape design or lighting?
Absolutely — and this is one of the strengths of working with Harkins Unique Landscapes. We offer full-service landscape design, hardscape installation, and landscape lighting all under one roof. Coordinating these together produces a more cohesive result than hiring separate contractors and trying to integrate the work after the fact. Most of our larger projects involve all three disciplines working together from the planning stage.
Do you offer hardscape repair for existing installations that are shifting or cracking?
Yes. Jon has rebuilt and repaired hardscape installed by other contractors throughout Iroquois and Kankakee counties. In most cases, repair involves removing the surface material, correcting the base (the underlying cause of the failure), and reinstalling. The goal is to fix the root problem, not just surface-patch a symptom. Contact us for a free assessment if you have hardscape that's deteriorating.
