Here at Concrete Restorations, we always say no two projects are the same. Each project presents its own unique issues and characteristics, that we build on even if its negatives. What I mean by that is, you are going to have to often deal with negatives such as cracks and settling along with other potential structural issues.
Looking at this walkway and entryway, we have several issues going on here. First, we have spalling, which is where the surface or the finish of the concrete is flaking off in small but, substantial chips. This spalling is about the size of a dime and appears to be like a concrete rash.
This is somewhat uncommon for walkways because two things cause spalling which are, overworking the concrete in large pours, which walkways typically are not large pours or freezing which is most likely here. When concrete is being finished, the water in the concrete comes to the surface allowing the finisher to trowel the concrete to finish.
This moisture rises to the surface and is sitting on top of the concrete and if cold enough can freeze causing the concrete to be compromised structurally and eventually pop off in a phenomenon called spalling. The second issues here is cracking. The first photograph looking down the steps displays settling cracks on the second, third, and fourth steps as shown in the first photograph above.
There was also settling where the steps pulled away, where the tread and riser come together, and had to be re-bared and re-poured in the third photograph above between the porch and the walkway. So there are some interesting issues on this project to find solution to and avoid what would typically be total replacement. However, if you are going to call your company Concrete Restoration System, you had better have solutions.
So the unique issues of this particular project are spalling, cracks and settling. So how do we deal with all the issues presented? To deal with the separation of the step, we demo sawed out a four-inch space where the step riser separated from the tread and drilled and set re-bar dowels to prevent future settling and poured new concrete. We then filled the spalling surface with epoxy as shown in photograph one.
We then took a right angle grinder and a crack chasing diamond wheel with a “V” shape blade to open up the cracks and filled them with epoxy and silica sand. We then re-opened those existing epoxied cracks again with the right angle grinder and crack chaser and began to carve a flagstone pattern into the entire step creating a unique flagstone look.
We also placed what are now joints into the risers of the step to create a look of placed cap stone as shown on the risers in the photograph above of the finished product.
To give these now created stones a natural stone like look, we installed our quartz epoxy system to obtain a grainy stone finish in a color selected by our client. The same process was used for the entryway or porch to achieve a one of a kind project that the client is absolutely thrilled with as illustrated above in our before and after photographs.
When we say no two projects are alike, we mean just that! After forty years in business here in the Denver area, we have proven ourselves to be uniquely creative taking each project and making it special for each and every client. Its just simply important!
