Handcrafted Stone Over Elevated Wooden Deck

A couple of homeowners in West Milford, N.J., were looking to enhance the curb appeal of their house by enhancing the front entryway. They initially contacted us about the possibility of resurfacing concrete steps leading to the front door and pouring a new sidewalk from the driveway to the steps.

During the conversation, they mentioned their desire to have a covered front porch, but were worried about the possible costs associated with such a dramatic change.

We saw an opportunity. We could use our custom overlay product to create the illusion of a masonry front porch, which would get faced with cultured stone on all of the vertical areas. Our idea was to go in the direction of deck construction rather than block construction, then put one of our cast-in-place overlay systems over the wood deck.

Choosing a deck over block eliminated the need for large-scale excavation to pour footings. This was a major cost savings, since we are in a freeze-thaw environment and excavation would have to go down nearly 4 feet. Our way, all the deck contractor would need is a post-hole digger to remove enough earth to pour what would be considered typical deck footings.

This also eliminated the need to get another mason on-site to run up block and then fill in behind the block wall. Since we are able to do our cast-in-place stone over wooden structures, we were able to use the same product on the elevated area, the steps, and the sidewalk leading to the driveway. This creates a continuous look over all horizontal areas, which typically can only be offered over masonry substrates. With our deck construction process, we were able to save the homeowners thousands of dollars.

The process 

The project began with a deck contractor removing the existing concrete steps, landing and bluestone sidewalk. He then determined the footprint of the new deck as well as the amount and placement of the footings that would be required to support it. The footings were dug, poured and inspected.

Once the footings were poured and the deck construction started, we came in to install a vapor barrier and pour a slab underneath where the deck and steps would go. When this was completed, he was then able to finish the construction of the deck, stairs, and the roof over the deck. This deck was built with 2-by-10s 12 inches on center, then wrapped with 3⁄4-inch pressure-treated plywood.

All wood substrates were then wrapped with tar paper in order to avoid direct contact with the wood and concrete, and galvanized wire lath was nailed into place on both the vertical and horizontal areas.

The next step was to pour our structural layer, which is heavily reinforced with PVA fibers and polypropylene fibers. This mix also utilizes several admixtures that increase the hydration of the cement and minimize the amount of water needed to make this high-fiber mix workable. After this mix is placed, it is scarified to ensure an excellent bond with our concrete overlay. This mix is applied to the deck and the steps at a thickness of 1 inch as long as there is pitch built into the deck. (If it is not, we must establish pitch in some way.) With the chemicals added to this mix, it is extremely moisture-resistant, which is a necessity when pouring over a wooden substrate.

Once the structural layer is set, we were able to begin our formwork for the cantilevered edges on the deck and the steps. We could then begin pouring our decorative layer, which becomes the cast-in-place concrete “tiles.” This mix is very similar to the structural layer except for the fiber dosage and the integral color. The length and amount of fibers is reduced to allow for clean cuts from our stamping tools. We are able to use any one of our 25 different patterns as well as any integral color to achieve the final tile color and shape. Each one of the impressions made in the wet concrete is then grouted to ensure the realistic look of a custom handmade concrete tile. When the grouting process is completed, the entire surface is densified with a lithium siliconate, then sealed.

Thanks to the advanced mix and the densifying, moisture transmission is dramatically reduced.

All of the vertical areas of the deck, as well as portions of the house and garage, were then covered using cultured stone. By enclosing the area underneath the deck and covering it in stone, we were able to create the illusion of a masonry porch.

Benefits of Installing an Overlay Over Wood

It offers custom handmade concrete in an elevated setting. It’s a more expensive and impressive look than the plastic look and feel of many of the composites on the market.

It’s heat-resistant (much more than any composite and to a degree that rivals stone), which is great for areas that may have fire pits or grills. The concrete is rot-proof and insect-proof.

This process provides a waterproof area underneath the deck which can then be used during inclement weather (if the deck is on the second story) or just for storage. And there is no need for expensive gutter systems that are prone to clogging.

It offers the potential for a continuous look across all horizontal surfaces — which could include the deck, steps, patio, sidewalk and pool surround, and even the driveway.

We can control the water flow. When installing surface drainage, we can direct the water to drain to gutters, scuppers, or just over the edge.

Even though we are in a pretty severe freeze-thaw environment, we guarantee that the decorative layer will not delaminate from the structural layer. We have seen people try to place tile or stone outside in a method similar to how it would be installed on the second floor of a home inside. When those surfaces are done this way outside, it is only a matter of time before water gets in and freezes, causing delamination.

It holds up much better in severe weather environments, such as freeze-thaw environments and near oceans, than exotic woods and other decking alternatives do.

This product has been designed to not need resealing. While sealers offer better stain resistance and a sheen, they are not necessary.

Overlays never have problems with fasteners or nails popping. Also, no splinters.

We offer a wide selection of patterns and colors — many more design options compared to composite deck materials.

Construction costs can be much more affordable compared to building a traditional masonry or steel structure of a comparable size.

Drawbacks to Installing an Overlay Over Wood

It is very difficult to introduce a new idea to the marketplace — especially when the idea is placing concrete on a wood deck.

Our process requires special chemicals to be added to create a high-performance mix that will create a very water-resistant concrete. These chemicals can be expensive.

Our mix need high dosages of fiber to work properly. It’s the fibers that allow us to work at a much thinner thickness, which means less weight on the deck.

Decks need to be designed to handle the weight of the concrete. Even though we are going relatively thin, they still need to be designed for the excess weight involved.

This work requires a highly specialized crew.

Getting material to the elevated surface is a task, and it needs to be done in a very efficient way since the concrete offers limited working time.

 

Stamped Concrete Morris County, NJ

This was a concrete pool with plain concrete surrounding it and a plain concrete patio near the house. The patio was in decent shape with only a few minor cracks, but really needed a decorative facelift. The pool decks was in very poor condition. There was severe settling, ice damage to the coping and extensive cracking. We were able to repour the the existing coping to complete repairs, then resurface the entire pool deck. We also built a decorative shear decent water feature in the place of an old diving board.

Porch, Patio, and Sidewalk in Bergen County

We resurfaced an existing porch area that originally had wet laid bluestone. The bluestone was set level which lead to water damage near the house. The homeowner removed the bluestone and did the necessary repairs on the house prior to us arriving to this job. We were able to correct their drainage problems and give them a look similar to the bluestone. We also did a newly constructed patio and sidewalk in the same pattern and color as the porch. The overall thickness of these are approximately 5″ and are reinforced with 1/2″ rebar and structural synthetic fibers.

Wayne, NJ Pool Deck Resurface

This was a pool deck resurface that had a couple of very interesting challenges. This was a very old pool with fiberglass walls and a concrete bottom. The existing coping was a piece of rubber in a metal track which had begun to get loose. The first challenge was to create a cast in place coping that would hide that metal track once the rubber was removed. Once the coping was completed, we could then correct a couple of drainage issues on the pool deck. We also honored the existing expansion joints in the slab in a decorative way by creating a brick row lock. Another challenge to this job was how to deal with the area of the pool deck next to the wooden deck. There was existing curbing there that was several different heights. We decided to turn this area into a decorative accent by creating a seat wall faced with cultured stone. We poured a heavily reinforced wall in front of the existing curbs up to the bottom of the deck. We then capped the wall with our cast in place concrete tile in a color that would match the coping. Once that was complete we faced the wall with the cultured stone. All work was done in a weeks time and since there was no demolition involved, there was no disturbance to the existing landscape.

Lake Mohawk, Sparta NJ, Concrete Tile

Custom cast in place concrete tile is an alternative to many of the hardscaping options that are on the market today.  If your in the market for something decorative, typically your options are:  real stone- while very attractive, its also very expensive. Concrete Pavers- very natural, but unless done correctly, has many short comings, even when done correctly has many maintenance concerns. Stamped Concrete-Can be a durable solution if done correctly, but usually tries to mimic a natural look and has faux grout joints.  Our concrete tile can be another option and avoid many of the shortcomings related to these other products.  Through years of research in development, we have a product that marries features of all of these products.  Concrete tile is made to order right on site, meaning it is completely custom.  Also since it is made in place, we can guarantee that it will not delaminate.  Here is what the Concrete Network is saying about concrete tile – “When installing tile in your home, you’re no longer limited to run-of-the-mill factory-produced ceramic, porcelain, or vinyl floor tiles. A new budget friendly, versatile, and long-lasting alternative is precast concrete tile, custom made for your application. Concrete tile can be used just about anywhere, indoors or out, including floors, walls, fireplace surrounds, pools and patios, shower enclosures, countertops, backsplashes, and building façades. In many cases, concrete tile sizes, finishes, and colors can be customized to suit your design needs.” (Courtesy of the ConcreteNetwork.com)

Sparta, NJ Entryway Resurface

This project began with the intention of resurfacing everything. However, with more investigation, the brick and limestone steps leading from the driveway were deemed to be not structurally sound. These were removed and repoured along with a portion of the sidewalk next to these steps. We also removed the little cheek walls on the porch that served no purpose. This would create more usable space and a cleaner look. Once the demolition was done, we applied lathe and a scratch coat to the porch, then poured a heavily reinforced “scratch coat” to correct the pitch problems and eliminate the large step coming out of the house. Once all of the structural work was done, we began to pour our cast in place concrete tile in the random ashlar pattern. The formwork was done in a way to allow for the application of Cultured Stone to the risers of the steps and the porch area. Once the stonework was done, we grouted everything with an uncolored natural grout. All work was completed in 3 working days, and even with the extra demolition, there was minimal disturbance to the existing landscape.

Interior Concrete Floors in Sussex County, Northern NJ

This is a recently completed interior concrete tile floor over radiant heat in Sussex County, NJ.  This project involved over 2,000 square feet over a wooden subfloor.  We first poured a heavily reinforced concrete subfloor to cover up the radiant tubes.  Once this concrete set, we began our concrete tile pour.  This consists of an integrally colored concrete mixed on site.  It is poured, textured, then stamped with cookie cutter style stamping tools, much different than traditional stamped concrete.  This is all actually grouted with real grout.  This is a cast in place concrete tile method that is unique to us and is often much more affordable than real stone tile.

Concrete Over Wooden Deck: Discussion with the President of Concrete Network

How to Cover Over Old Wood Decks and Floors with Decorative Concrete

You will be intrigued just as I was by the concept of poured concrete over weathered wood decks and interior wooden floors that have settled unevenly in old houses. Think how much nicer these areas could look as long as they can be made structurally sound enough to handle the addtional weight.

Unique Concrete has been involved in this use of stamped concrete for several years. Most of the work in these areas have been retrofits which are more difficult to address than new construction. The process has worked so well that Unique Concrete would like to promote the concept more toward new decks and areas that could be designed from scratch to handle the additional weight. Then you could have the beauty of custom masonry in elevated areas over wood and in a cost effective manner.

Barry Fisher of Unique Concrete wrote me the following letter:

Hi Jim,

My sons and I would like to share a concept with you that could develop into another area for decorative concrete to expand. This concept involves placing an inch and a half of patterned concrete on the horizontal areas of wooden decks.

The process offers people another alternative for decks and promotes the lasting beauty of custom masonry. I have attached several before and after pictures of retrofits that we have been involved with recently.

The benefits for using concrete on the wear surface are numerous:

Besides the aesthetics, you now have something that is rot proof, insect proof, easy to maintain even in the harshest climates, and will retard the spread of fire.
On elevated decks, this decorative solid surface will provide you with a rain-free area underneath and if you choose to screen in your deck, it will aid you in creating an insect free environment.
Our oldest decks go back 20+ years, and there are no problems that I’m aware of.
