How to Cover a Concrete Foundation Wall on the Exterior

See how this homeowner transformed a large concrete foundation into a finished, high-end exterior feature—without rebuilding.

Kenneth Stauffer

Senior Project Coordinator / Training Supervisor

Hi, I’m Kenneth, and I worked with this homeowner on improving a large exposed foundation area that was taking away from the home’s overall appearance.

The upper portion of the home looked clean and modern, but the lower section—bare concrete block—felt unfinished and out of place.

The homeowner didn’t want to rebuild or re-side the entire home. They just needed a way to cover the foundation and make it look intentional.

Covering a Foundation Wall Without Rebuilding It

Update a Concrete Block Wall • Installs Over Concrete Block

Instead of removing or replacing the concrete, we installed stone veneer directly over the surface—turning a plain foundation into a finished architectural feature.

✅ Installed directly over concrete block

✅ No demolition required

✅ Completed in days, not weeks

From Exposed Concrete to a Finished Exterior

A simple upgrade turned this builder-grade exterior into a clean, custom look adding depth, contrast, and a high-end finish without major construction.

Best representative I have talked to

Kenai Kenai Panel

Ellie is the best person I've talked with as a representative from a company in years. She was informative and knew what she was talking about. She answered my questions accurately and politely. She kept in touch until I got the product samples I had ordered. She did not high pressure me to buy something. She estimated the amount of stone panels I would need and gave me a good total cost. When I called back to place my order, I asked to speak with her again. I actually got her.

Beautiful Results

Stacked Stone Kenai

We were very pleased from the ordering process to our finished project. Evan helped us determine quantities and finishing products. The product came well packed and undamaged. From start to finish we worked on this project 2 days. Not bad for 2 senior citizens. We love the way it looks and are hopeful GenStone will provide the insulation we are looking for on this exposed wall.

Wish I had more places to use Genstone

Stacked Stone Desert Sunrise

Great product it was a breeze to install and all it needed was a hand saw and the caulking gun and the supplies provided by Genstone. But I want to compliment the staff at Genstone for their assistance. Bri and Zach were very helpful. They were very quick to fix a problem with my order and I had my new order within 2 days. Thank you very much. I only wish I had more places in my townhouse to use Genstone. Thank you
