Why Experience Matters

Why Experience Matters

When considering who you choose to contact when looking to hire a concrete company, it is important to consider what type of concrete contractor you are hiring.  Concrete companies that are geared toward doing concrete walls and foundations are probably going to be the best at those types of projects. Concrete paving projects like commercial parking lots and gas stations are normally done best by small commercial contractors that pour a lot of parking lots. When it comes to decorative concrete projects like concrete staining or stamped concrete, those projects are done best by an experienced decorative concrete company. Experienced decorative concrete contractors will be able to identify your needs and figure out how to best achieve that result.

 

Many concrete companies advertise stamped concrete services. But the simple fact is that if they don't spend a lot of time doing something, it's very hard to truly become an expert at it. Stamped concrete is a highly specialized service that has a huge learning curve and there are many nuances that only stamped concrete companies that have completed hundreds of stamped concrete projects will know. This experience makes a huge difference in the final product. A small mistake can ruin the entire look of the project.


Concrete stamping is a skill set that is learned over time and is executed using specialized tools and techniques, combined with artistry. Being able to solve problems while the concrete is wet is a crucial skill for a great final product.


Superior results for stamped concrete begin well before the concrete arrives. Having enough manpower and all the necessary products may seem obvious for construction but it is vital in concrete, where the product is on a ticking clock.  Once the concrete is mixed, it will be hard in a matter of hours, whether it's done right or not. 

 

After the concrete arrives, the need to for experience begins. An inexperienced contractor may mix the integral color incorrectly in the truck, either by using the wrong quantity or by not ensuring that the color is mixed thoroughly, leaving streaks and uneven color. 

Some projects require more than one load of concrete. Without the proper mixing technique, an inexperienced contractor may end up with a large color contrast between pours.


Use of admixtures to delay the set of concrete from one load to another is often necessary to make sure all concrete remains soft enough to stamp throughout the project. Knowing how fast a crew can stamp is crucial for using these admixtures and it is piece of the puzzle only experience brings.


Once the concrete is poured, finishing the concrete completely in a continuous manner is necessary. Returning to finish edges or missed areas will result in a slab with different coloration in those areas. Many projects done by an inexperienced contractor may show where the release powder was thrown out, then finished in. Not only is this bad for the concrete but it creates a very odd and visible look. The concrete is darker in those areas, and it is obvious every place that finish was applied.


After finishing, experience is needed to know when stamping should begin. Depending on weather conditions, the stamping window is generally less than two hours from start to finish. If the contractor starts stamping too early, the concrete will stick to the stamp or create a sunken spot. If the contractor begins too late or stamps too slowly, they will not be able to get an impression into the concrete with the stamp.


Once the stamping begins, understanding how the pattern fits together and how stamps need to be placed is key. I have seen many completed jobs where it is obvious that the contractor didn’t have the experience using the pattern and set the stamps down incorrectly. They also didn’t know how to fix the mistake in a timely manner and just left it and tried to move on. No matter how good a contractor is, mistakes will still happen. A footprint from stepping off the pattern accidentally, a dropped stamp or a spot where the concrete stuck to the mat- these things can occasionally happen to even the best stamped concrete company.  Understanding how to fix these problems quickly and get back to stamping makes the difference between an experienced and inexperienced contractor.


Another important aspect to many stamped concrete jobs is being able to start the pattern square and keep it that way throughout the process. “Growing” or “shrinking” the stamps in small increments as they are placed is another skill that develops with experience. As the stamping process nears completion, other skills may be needed. When stamping around a pool, island or firepit, it is often necessary to being able to stamp in textures or apply dummy joints to assure that the pattern blends correctly. When stamping around an object, it is not possible to keep all of the stamps connected side to side. A contractor starts on one side and stamps around to the other. Where the stamping comes together at the start and finish, the pattern will not line up, no matter how much care is taken. Stamps always move slightly and often have very small gaps between them. As a result, moving a stamp 50 different times with a gap of 1/32” of an inch means the final pattern will be off by several inches by the time the two sides meet, not to mention differences in squareness. Being able to fix this problem is another difference experience makes.


Once the stamping is done, finishing the job the next day also requires an experienced contractor. Areas in the sun will get harder quicker than shaded areas. This means that the results may look different between those areas. Sun areas may be lighter or darker than the shade areas, as more or less release will take to the concrete. Knowing how to adjust this difference by removing release or adding release to achieve uniformity is key to a great result.


The above are just a few of the things that separate an experienced stamped concrete contractor from one that only does stamped concrete a few times a year. Without the requisite experience, it's unrealistic to think the outcome of stamped concrete from an inexperienced contractor will approach the quality of one well versed in the many tricks of the trade.


In addition to the techniques above we learned over the years, we also use other processes when creating borders and applying release that create a subtle difference in quality between our stamped concrete and others in the business.


When you are choosing a stamped concrete contractor, you should ask how many stamped concrete projects they have done. At Rockford Stamped Concrete, we have completed more than 250 projects, so you know we have the experience to make it look great! 


You should also look at the pictures your potential contractor has. I have seen pictures posted by other contractors where dark blotches and huge sunken birdbaths are clearly visible because the contractor tried to stamp the concrete while it was too wet. Other times, ridges and lightly colored areas and mat marks are visible where the contractor either missed texturing an area or didn’t overlap the texture mats correctly. Some of these photos show darkened edges where the contractor finished release into the surface with a tool after the release was applied.  Be sure to look closely because many of these pictures won’t even show the areas where the contractor failed to tamp the stamp deep enough to leave an impression, or the concrete got so hard there is almost no texture inside the stamped stone outline.


While these things are issues that affect the quality of the job, the biggest problem these pictures show is that the contractor who did the work doesn’t even realize it was bad work! Contractors don’t want to show off their mistakes, so posting these pictures shows the lack of knowledge about what a quality result even is. With concrete, these mistakes are not as obvious to a homeowner as unlevel siding or missing singles but to an experience decorative concrete contractor, it’s the same thing. These mistakes are glaringly obvious.


Many times, the inexperienced contractor will bid a project for less money because he does not realize the time, steps and manpower necessary to do the job correctly.  While price is an important factor when considering who you will hire, it is wise to think about the following ideas as you make your decision:


"It's unwise to pay too much, but it is worse to pay too little.

When you pay too much, you lose a little money -- that is all.

When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do.”

-John Ruskin (1819-1900)


If you saved some money by choosing the cheapest contractor but the final result is a product that doesn't look good, was it worth it?  You will be looking at that concrete for many years to come.


As stamped concrete contractors, we owe our clients the best quality work.  That quality comes with experience.  And that experience is worth something.

One of the least appealing aspects of having concrete work done at your home is that it often requires an existing lawn to sustain some damage. Unfortunately, yard damage of some sort is inevitable when working with existing yards. Some damage is to be expected just due to the sheer weight of the materials involved.

Weather is the single most important factor that influences our schedule. We usually don’t pour if there is a good chance of rain. It’s not that we hate getting wet, it’s the fact that rain can damage freshly placed concrete and necessitate an immediate replacement.

The scope of work is listed to make it clear what the contractor will do on your project per the estimate. It is important to read and understand what will be done so that both the client and the contractor have the same expectations. Many times, what a customer expects and what a contractor does are not the same thing. I

One question many people ask is which product is best- pavers or stamped concrete? This is because the two are viewed as competing products-to homeowners and to contractors. Both are made from the same material-concrete. Since most concrete companies don’t install pavers and most paver installation companies don’t do stamped concrete

I have received quite a few calls over the years with regards to sealer issues. A few have been our own, most have not. The usual question is “Why is my sealer white?” This issue is almost invariably linked to moisture issues. While sealers are meant to be used outside, they are also meant to go on in thin layers. The reason for this is that thin layers allow the sealer to be “breathable” which means it allows the moisture to escape from both the concrete slab and the ground below it.
Reinforcement — Rockford, MI — Rockford Stamped Concrete
24 Feb, 2023
One of the factors in the cost and durability of your concrete is the use of reinforcement. Reinforcement products are extra products added to the concrete, though they are not visible once the concrete is poured. Reinforcement is not a requirement for concrete, but it is beneficial to the concrete product in terms of adding strength and longevity. There are several different types of reinforcement, and they are used in different applications. The primary type of reinforcement we use is wire mesh reinforcement. Wire mesh is a grid of 6-inch welded wire squares (think of a fence) that is placed the concrete. This mesh holds the slabs of concrete together and increases the tensile strength of the concrete. It is used a lot in commercial construction but not much in residential concrete construction. Most homebuilders do not use wire mesh in their flatwork. Another type of reinforcement commonly used is called fiber mesh. Fiber mesh is small fiberglass hairs that are added to the concrete mix. There are different types of fiber mesh used for residential and commercial applications. Residential fiber mesh tends to almost be invisible to the eye and you have to look at it very closely to see it. Each unit resembles a small piece of spiderweb. Commercial fiber mesh is coarser and looks like chopped up horsehair. These fibers are much longer and larger diameter than residential fiber. Another type of reinforcement is rebar reinforcement. Rebar is a bar of round steel that comes in various lengths and diameters. We use rebar reinforcement in several different applications. We use short pieces to reinforce corners. We also drill short pieces of rebar to attach flatwork to the foundation. This keeps the concrete from sinking down or pulling away from the house. We also use rebar to attach a sidewalk to a porch. A third common use is connecting sets of steps. Rebar helps to hold the steps together and creates additional tensile strength.
Powder vs Liquid Release — Rockford, MI — Rockford Stamped Concrete
24 Feb, 2023
Stamped concrete release is the secondary color we use during the stamping process. The release keeps the stamps from sticking to the concrete. There are two different types of release. The release used by most contractors is liquid release. Liquid release is also called bubble gum release because it is scented to smell like bubble gum. This product is a clear liquid solvent that is applied to the surface of concrete with a pump sprayer. After concrete is stamped, the solvent will evaporate. The following day the stamped surface will be washed and antiqued using a solution from a pump sprayer. This antiquing is sprayed on the concrete surface and gravity causes it to settle into the joints and areas of lower relief. The second type of release that is used is a powder release. You can think of this product as a colored flour or dust. This dust is spread over the surface of the concrete in a thin layer. Then the stamps are placed and stamped into that dust. There are pros and cons to using both types of release. Liquid release allows the contractor to see and fix the surface impression made by the stamping tool more easily than powder release. With powder release, it is harder to see the depth of the impression that is made, and improper application of powder release can lead to streaks and divots. At Rockford Stamped Concrete, we feel that the benefits of powder release outweigh those of a liquid release. With liquid release, it really takes well trained eye and multiple attempts to make it the product look good. Liquid antiquing can leave dark puddles that are often compared to dirty water. It does not tend to leave the natural and even appearance we achieve with powder release.
Online Concrete Cost Guides — Rockford, MI — Rockford Stamped Concrete
24 Feb, 2023
One of the first steps we take when researching home construction or home improvement projects is figuring out the different options available and researching the costs of those options. There are cost guides available at various sites online. While I can't say how these online guides work for other trades, they are not an accurate predictor of cost for concrete, or even for products that are considered concrete competition, like asphalt, pavers, or natural stone. Part of these inaccuracies start with pricing of concrete as a material. Several online guides list the cost of a cubic yard of concrete between $90 and $100. This pricing isn’t even close. A more accurate estimate would be in the $150 to $175 /cubic yard range…. and that's for contractor pricing. Pricing also depends on the number of qualified contractors in an area, supply versus demand, the area of country you live in, and the quality of the work that you receive. Quality work always costs more than substandard work. One site I found online stated the average cost of stamped concrete is $8 to $28 a square foot. Really? How is this even an average? The high end is more than three times the lower end. That’s not a very helpful pricing guide for a homeowner. I can tell you that pricing in our area is closer to the middle of this range than either end. Even then, there’s still a large range, and many factors are involved in that price. Please see our Concrete Cost and Economics of Scale blog topics for more info on those factors. In my opinion, the best place to look for pricing is not some online guide that you find but rather from a friend or neighbor that had similar work done recently or in an online forum. Forums like Reddit or Quora provide a much more accurate idea of what the concrete will cost for you to do. If that price works for your budget, get at least three estimates from experienced contractors and make your choice from there.
Overlay Cost — Rockford, MI — Rockford Stamped Concrete
24 Feb, 2023
Are overlays less expensive than concrete? One of the common misconceptions I see online is that concrete overlays are less expensive than replacing concrete. This is usually untrue except for a select few instances. There are very few places where an overlay makes sense. In the vast majority of cases, we recommend tearing out the old concrete and replacing it with new concrete. The times an overlay makes sense usually have to do with the mess created with a replacement or damage that could happen to structure or infrastructure. In my opinion, the three instances where an overlay might make sense would be an interior floor, a pool deck or a porch. While a stamped concrete overlay on an interior floor makes practical sense in that it saves the mess of tearing out the existing floor, it doesn’t usually work from a financial standpoint. Stamped concrete overlays cost quite a bit more than most flooring materials, even high-end travertine tile or wood flooring. Most people just choose those other products. Occasionally we will do an overlay on a porch because it eliminates the need to structurally support the porch while concrete is torn out. The prep work for an overlay is also less labor intensive than setting porch forms. I have also seen instances where part of a building structure is placed on 4" concrete rather than a foundation. This can happen in older cottages or unapproved additions. In these cases, removing concrete flatwork will cause a wall to sink or exterior masonry to detach from the wall. Pool decks are an area where overlays make the most sense. It can be very expensive to tear out a pool deck, because there are many things that require caution and make tear out a time-consuming process. The coping can easily be bent when removing the concrete. The bonding wire that runs around the pool connecting metal panels, handrails, ladder brackets and diving board jigs can be yanked out. It’s also easy to wreck a skimmer box or drop concrete into the pool and gouge the interior of the pool. Most pools have a fence around them, so getting in and tearing the pool deck out becomes a task that usually requires hours of jackhammering or total fence removal. The most popular type of overlay that we use around pools is called a spray overlay. A spray overlay is a cement product that gets sprayed over the existing concrete using an air compressor and hopper gun. After spraying, the overlay is knocked down with a trowel. This product has a few different names depending on who makes it. Common trade names are spray deck, sun deck or kool deck. A great feature about using this material is that the texture makes the pool deck feel cooler on your feet than the standard brushed concrete beneath it. The material is also very easy to use over existing substrates. It is thin (about the thickness of a credit card) so it will not create a high build above the existing pool coping. It is easy to make into borders and designs and is available in many different colors. We use this same spray overlay to cover up unsightly retaining walls or porch faces. Spay overlays are less expensive than a pool deck replacement.
Most Common Concrete Design — Rockford, MI — Rockford Stamped Concrete
24 Feb, 2023
What type of stamped concrete pattern is the most popular? Stamped concrete patterns follow trends, and it seems like there is a new favorite every year. The most popular patterns are not necessarily the right ones for your home. What really matters is what you like and how it will blend with your home. Too much of one thing can feel excessive. Varying textures is a good idea in most landscaping layouts, so if you have a ground level wooden deck adjacent to where you would like a new patio, a wood pattern would probably not be the best choice. The same can be said for brick. If you have a brick home, consider a pattern other than brick. Also consider the scale of the pattern and the area it will be used. A larger size patio or pool deck will look better with a larger pattern, while a smaller sized area (like a sidewalk) will probably look better with a pattern that is slightly smaller in scale. If you like the squareness of an ashlar pattern, consider using the ashlar stone (TM 100) or grand ashlar pattern for a large patio. If you want the same look with a walkway, consider using ashlar cut slate instead. While grand ashlar and ashlar cut slate are almost identical when it comes to texture and layout, the individual stones in the grand ashlar pattern are larger than the stones in ashlar cut slate. Stamped textures are a good choice for both large and small areas. In large areas, we often use decorative saw cuts or bands to add visual interest. Using a radius cobblestone or compass somewhere in textured areas is also a good way to customize your concrete project. Our most popular stamped concrete patterns throughout the last decade have been flagstone, ashlar stone (TM 100), and heavy stone texture. Flagstone is a timeless pattern because it has been used for patios and walks for many years. The flagstone pattern has a random and angular look. Ashlar stone provides a traditional clean and classic look. Heavy stone texture provides the endless visual interest of a stone surface without using individual stones.
