How to Extend Your Concrete Patio With Pavers

With an open concrete patio out back, several newer homes are sold, usually just large enough for a small barbecue, a few tables, and a plant or two. A traditional slab patio is just too small for entertaining or some real form of enjoyment for homeowners who are serious about using their outdoor living room.


The solution: Expand the patio with concrete. It may become costly to pour additional concrete. Permits are required to pour concrete in many cases, and that typically means hiring a contractor, pushing the cost of this project into the thousands. Extending the concrete patio with pavers is an alternative to pouring more concrete.


Patio pavers offer homeowners many benefits.


  • They are simple to build, so homeowners can make it a weekend do-it-yourself project to expand a concrete patio.

  • Pavers come in a wide range of shapes, sizes, colors, and materials, providing the versatility to homeowners in creating extra outdoor living space.

  • Pavers may be used to create large or small spaces and to render the room as formal or casual as desired by the homeowner.

  • They are also easy and inexpensive to repair.


1. Plan on Paper

The DIY paver project gets simpler with proper preparation and planning. The trick is planning. To scale up the current patio, house, and any landscaping that will not be removed, use graph paper to draw. The drawing helps with materials for planning and ordering.


2. Buy Enough Pavers for the Job

For a regular-shaped project, such as square or rectangular, the number of pavers required for the project can easily be figured. Buy enough pavers to cover the new patio space's square feet, plus 5% for edge cuts. More cuts would need irregularly formed patios, so an additional 10 percent of the content should be purchased.


3. Map Out the Area

Outline the place where the patio is going to be. To hold the string or hose in place, use a string or a garden hose for the outline and stakes. Take into account that guards would be used to hold the base and pavers in place while setting out the outline, and the base should stretch approximately the width of the paver beyond the guards, generally 4” to 6”.


4. Prepare the Slope

The preparation of the slope is one of the most critical aspects of laying pavers. For proper drainage and to prevent rain from pooling, all patios should slope away from the house (or in this case, away from the current patio). The slope should be at least 1/8" over one foot, so the slope should be 1" from the back (the edge which meets the existing patio) to the front if the patio is 8 'long. For best drainage, a slope of 1⁄4' is suggested by many paver installers.


5. Excavate

Excavating will involve cutting sod or grass in most situations. In order to make this step simpler, a sod remover or sod cutter can be rented.


The height of the pavers and whether the soil is damp will depend on how much soil you remove. (You'll want to dig down deeper if the spot is very wet.) For the sand sheet, the foundation is usually 5" plus 1.5" plus the height of the pavers. The base layer for the sand and the height of the pavers should be up to 12' plus 1.5' in very wet soil.


Strings can be run from stakes on the existing patio to the front of the new patio area after excavation and modified to display the appropriate slope. Running crossways with strings would also ensure that the pavers are level around the entire patio.


6. Lay the Base Material

A crushed rock content is typically the foundation. At one time, it should be laid no more than 2" deep and then compacted. A hand tamper can be used to compact the material for a small area, but use a plate compactor for larger areas that can be leased for the project. Great stability under the pavers is guaranteed by compacting the base layer. Laying it only 2 inches at a time guarantees that the whole foundation is well compacted. To assist in the compacting, the base layer may be watered. Continue to add and compress the base material until it has reached the proper height for the base. Be sure to lay the base outside the patio area to ensure the pavers at the edges are safe.


7. Put in Edge Restraints

Edge restraints help to keep in place the pavers. They are usually made of wood, metal, or plastic and are mounted with 12" spikes around the edge of the project. The edges will have to be cut to outline the curves in the project for irregular-shaped patios.


8. Pour a Sand Layer

In a paver courtyard, the sand behaves like glue. Use coarse sand and screed it smoothly, not more than 1.5” thick, to the desired height. A small project with a 2'x4' can be screened, but the sand should be laid and screened in 50 to 100 square foot sections for large projects, finishing one segment before moving on to the next. To measure the parts, aluminum pipes can be laid down, then lifted off as required, and the groove left behind can also be filled in and scraped.


9. Lay the Pavers

When it's time to lay the pavers, the job is almost over. Laying the pavers is simple, after all the hard work of preparing and laying the foundation. Start laying them, preferably adjacent to the current patio, at a 90-degree corner. Act out from the new patio, laying the pavers in the sand in straight lines. They should be put directly into the sand where they will lie, not slid into position as the sand underneath will be displaced and should be 1/8' apart. Stand on the pavers already laid, rather than on the sand, to begin the work. Using a string as a scale, check from time to time that the pavers are straight and level.


First, lay all of the entire pavers and then return to make the required cuts at the edges. Using a masonry saw, pavers can be removed. Make sure to use protective goggles and meet all of the safety instructions of the manufacturer.


10. Tamp It All Down

Using the plate compactor to tamp the pavers into the sand after all the pavers are laid flat. By sweeping a thin sand into the joints between pavers, finish the job. This will lock into place the pavers. Sand is likely to need to be swept a few times through the joints as it can settle with use and rain.


11. Seal It

The pavers can be sealed to ensure lower maintenance. A sealer can shield the pavers from moisture, hold the sand in place between the joints and help prevent the growth of weeds.


It's time to enjoy it now that the patio is done. Invite friends and family, have a barbecue, and enjoy a job well done with the products. A paver patio can last 10-20 years and provide plenty of pleasure.
