E5® Internal Cure

Internal Cure Technology That Improves Strength and eliminates maintenance and sealing

E5® Internal Cure

Traditional concrete curing relies on surface treatments and topical sealers that wear off over time. Homeowners are often told to reseal every few years, adding cost, maintenance, and uncertainty.

Cornerstone Concrete adopted E5® Internal Cure to eliminate those problems entirely. E5® works from inside the concrete, slowing the curing process so the slab reaches its full strength potential. The result is a denser, stronger surface that resists cracking and eliminates the need for ongoing sealing. E5 makes our broom finished concrete Maintenance Free For Life. It’s ideal for driveways, sidewalks, and patios where long-term durability matters most.

Our Proven 4-step Process

E5® isn’t sprayed on later—it’s built directly into the concrete from the start. That’s why we use our proven concrete driveway installation process, a structured, crew-based system where each step is handled by specialists.

1. Tear-Out Process

We safely remove existing asphalt or concrete, address sub-base issues, and prepare the site for proper drainage and stability.

2. Set-Up Process

Forming is set in place for your custom project. Final grading checks are done along with ensuring proper thickness, slope, and long-term performance.

3. Pour Process

Concrete is placed, finished, and detailed with precision using mixes selected for strength and durability.

4. Cut and Clean Process

Control joints are cut to manage cracking, and the site is cleaned thoroughly. Complimentary dirt and seed makes your property ready to enjoy.

This streamlined approach improves quality control, reduces delays, and delivers stronger, longer-lasting driveways.
