How to Install Concrete Pavers on Existing Concrete Patios

Concrete pavers add a touch of elegance to your old concrete patios, so most home owners like to upgrade their old, damaged patios with good looking concrete pavers. Using concrete pavers for your backyard is a cost-effective way of upgrading it and it also lasts longer. Concrete patios tend to accumulate stains and have cracks and craters within a few years, which make your backyard, look ugly. The best way to upgrade it is by placing pavers on it and it is much easier than mending the old one. The obvious question that arises in this is, whether you can lay concrete pavers on an existing concrete patio.

You’ll be delighted to know, the answer is Yes! To start with you have to make sure that the existing patio is relatively in good condition and it is levelled. Depending on the condition of the porch/ patio, you may apply a thin layer of concrete to make it levelled throughout. Once it is done you can start applying the gravel/ bedding sand which is applied for better settling, draining and expansion/contraction of the concrete pavers.

Concrete paver manufacturers say that it is best done if apply a layer of coarse sand which is about 1/2″ to 1”. To avoid drainage problems, cracking and settling troubles, you should keep the following tips in mind:

  • Drainage Issues: Drainage is the biggest problem when you are applying pavers on an existing concrete patio. The water is unable to reach the ground and tends to puddle. To solve this problem, make sure the patio has sloped properly to let the water drain pout of the blocks or you can drill holes at regular intervals so that the accumulated water seeps through the ground.
  • Sand in Joints to make it Long Lasting and Firm: Once you’ve finished laying all the concrete pavers, fill the remaining gaps with polymeric sand. Polymeric sand is permeable and is done properly it also allows the water to slide off the surface without accumulating.
  • Edging: Edging is very important for laying concrete pavers so that sand and pavers don’t settle and squish around. Do the edging in such a manner that it allows the water to drain, other it will be filled with water during rainy season.
  • Height: The new upgraded patio will be up to 3” higher than the old one. Make the transitions to the other areas accordingly. You may require installing flashing in order to keep the water away from your house.

If the old concrete is in very bad condition, the best way is to rip it off and start from scratch. You can also increase the size of your patio by digging the soil around it and applying a proper gravel and sand bed in such a manner that the old and new areas are perfectly in level. However, the new area will tend to settle making the patio uneven.
