Concrete Services
From residential driveways to commercial parking lots, RCC Masonry & Concrete delivers expert flatwork and structural concrete built to last through Northern Illinois winters.
The Science Behind Concrete That Lasts
Most concrete failures in Northern Illinois come down to one thing: the mix wasn't designed for the environment. McHenry and Lake County endure over 80 freeze-thaw cycles per year, combined with heavy road salt exposure and expansive clay soils that shift with moisture. Generic concrete poured without the right air entrainment, PSI rating, or reinforcement will crack, spall, and heave within a few seasons.
At RCC Masonry & Concrete, we approach every pour as an engineering problem. We analyze your site's soil conditions, drainage patterns, and load requirements before selecting the right mix design, reinforcement strategy, and finishing technique. This is why our concrete outlasts the competition by years.
Why Illinois Is Harder on Concrete
- 80+ freeze-thaw cycles/year — water expands 9% when it freezes inside unsealed pores
- Road salt exposure — chloride ions accelerate surface scaling and rebar corrosion
- Expansive clay soils — soil heaving puts enormous upward pressure on slabs without proper base prep
- Short pour windows — concrete must be placed, finished, and cured within tight temperature ranges
From Ground Up: How We Build Every Slab
A step-by-step look at the process that makes RCC concrete outlast the competition.
Site Evaluation & Soil Analysis
We evaluate your site's grade, drainage flow, soil type, and existing utilities. For problem soils (common in McHenry County's glacial clay), we specify deeper excavation and thicker aggregate bases to prevent heaving.
Excavation & Sub-Base Preparation
We excavate 4-8 inches below finished grade and install compacted CA-6 crushed stone in lifts using a plate compactor. This engineered drainage layer is the most critical step — it prevents frost heave and settlement that causes cracking.
Reinforcement & Form Work
#4 Grade 60 steel rebar is set on chairs in the lower third of the slab — where tensile stress concentrates — and tied at every intersection. We position expansion joints at all fixed structures. Forms are set to proper pitch for drainage.
Mix Design & Pour
We specify air-entrained concrete (5-7% air content) in 3500-5000 PSI mixes depending on application. Air entrainment creates microscopic bubbles that absorb freeze-thaw pressure. The concrete arrives in metered trucks and is placed within 90 minutes of batching.
Finishing & Control Joints
After screeding and bull-floating, we cut control joints at intervals no greater than 2-3x the slab thickness to control where cracks form. Broom, stamped, or exposed aggregate finishes are applied before final set. Edges are tooled for clean, professional lines.
Curing & Protection
We apply liquid curing compound or wet-cure with blankets to ensure the concrete reaches full strength over 28 days. In cold weather, we use insulated blankets; in heat, we schedule early-morning pours. Sealer is recommended after 30 days.

Real Projects, Real Results
Here's what recent concrete projects look like from start to finish in McHenry and Lake County.
Crystal Lake, IL
Challenge
A 40-year-old driveway with severe frost heave damage and tree root intrusion. The homeowner needed a surface that could handle two SUVs and a boat trailer without cracking.
Our Approach
Full tear-out and removal of 680 sqft of failed concrete. Excavated 8 inches, removed root mass, installed 6 inches of compacted CA-6 aggregate. Poured 4,000 PSI air-entrained concrete at 5 inches thick with #4 Grade 60 rebar on 24-inch centers. Broom finish with tooled edges and sealed control joints.
Result
Completed in 3 days from demo to finish. The driveway now handles daily trailer loading without stress. Proper pitch eliminated the standing water problem the old driveway had near the garage.
Woodstock, IL
Challenge
Backyard was a muddy slope after spring rains. The homeowner wanted a 450 sqft entertainment patio with a separate pad for a fire pit, connected by a walkway, all with a natural stone appearance.
Our Approach
Regraded the slope for positive drainage away from the foundation. Installed 6 inches of compacted base on the fill area. Poured 4-inch slab with fiber mesh and wire reinforcement. Applied Ashlar Slate stamp pattern with Desert Brown color hardener and Charcoal release agent. Sealed with high-gloss acrylic sealer.
Result
Transformed an unusable backyard into a three-season outdoor living space. The stamped finish eliminated the need for natural stone at less than half the cost, and the fire pit pad was positioned with proper clearance from the house.
McHenry, IL
Challenge
A 2,400 sqft section of a retail parking lot had sunk 3 inches due to poor original compaction. Potholes were forming and the surface was breaking apart under delivery truck traffic.
Our Approach
Saw-cut and removed the failed section. Discovered the original pour had no sub-base — just concrete on clay. Excavated 12 inches, installed geotextile fabric, then 8 inches of compacted CA-6. Poured 6 inches of 4,500 PSI concrete with #4 Grade 60 rebar grid on 18-inch centers. Finished with light broom for slip resistance.
Result
The new section is flush with the existing lot and handles daily delivery truck traffic. We installed isolation joints at the boundary to prevent differential movement from cracking the new slab.
The RCC Difference
Our Build Standard
Every slab we pour in McHenry and Lake County follows the same engineering standard — no shortcuts, no substitutions. Here's exactly what goes into an RCC pour.
4,000 PSI Air-Entrained Mix
Northern Illinois puts concrete through 25–30 freeze-thaw cycles every year. We pour 4,000 PSI air-entrained concrete as our residential baseline — the microscopic air bubbles give freezing water room to expand without fracturing the slab, and the higher cement content resists surface scaling from de-icing salts.
#4 Grade 60 Rebar on Chairs
We set #4 Grade 60 rebar on chairs so it stays in the lower third of the slab — where tensile stress actually concentrates when soil shifts beneath it. Cheap wire mesh is usually 'pulled up' by hand during the pour and ends up at random heights or flat on the sub-base, where it does almost nothing to stop cracks from spreading.
Compacted CA-6 Limestone Sub-Base
Concrete is only as good as what's under it. We excavate to proper depth, place 4–6 inches of CA-6 crushed limestone, and compact it in lifts. Where we find heavy clay sub-grade — common across McHenry County — we treat and stabilize it first, because untreated clay swells and shrinks with moisture and is the #1 cause of differential settlement.
