Paving Stones

Brick patios are low maintenance and environmentally friendly, not to mention they are the entertainment hubs of most yards. They enable you to be immersed in your yard while enjoying the company of your friends and family.


  • Add polymeric sand to any joints as necessary. Simply take a cup of polymeric sand and pour some over the required joints, then sweep off any excess. Ensure that the surface is clean then mist with water and leave to set for 24 hours; to work properly, there cannot be any rain during the next 24 hour period. To ensure you have the proper polymeric sand, you can purchase it through Greentree Outdoor Living.
  • Cleaning can be done with a pressure washer and, if needed, soap or any other concrete cleaner can be used.
  • Sealing is not required however a sealer can be applied to bring out a deeper, richer colour in the stone. Once sealed, we recommend resealing every 3 years.
  • If you feel the stone is too slippery, sand can be spread on the stone prior to the sealer being applied thus creating a grit texture.
  • If a stone has sunken in, remove the effected stone then put polymeric sand beneath the stone. Re-insert the stone and add polymeric sand to the joints using the same method as stated above. The same can be done to replace a cracked stone.
  • The polymeric sand will control weeds growing between the stones. If you find weeds are growing in an area, remove the weeds then fill the joint with polymeric sand using the method stated above.


  • A 5 year workmanship warranty exists on hardscaping construction performed by Greentree.
  • Paving stones that have sunk due to compaction or movement and are visible or causing drainage issues will be covered for repair a maximum of 2 times during the 5 year period.
  • Settling that occurs below 1 foot of subgrade will not be covered by warranty.
  • Greentree is not liable for any cracking, chipping, discolouration and/or disfiguration of material that may occur after installation. This includes damage from de-icing salts or other products administered to natural stone or concrete.

Frequently Asked Questions

  • Q: Are all of the paving stones the same colour?
    A: Each paving stone material comes from the same quarry so they are all the same type of stone however because they are natural stones, there are slight differences in the shape, colour and texture. Concrete paving stones however are quite precise in their shape and texture but can change slightly in colour depending on the batch and age.
  • Q: Because they are natural stone do I have to seal my paving stones?
    A: Our paving stones are non-porous: they do not have to be sealed as there is no concern for frost damage. Also, they are much more resistant to staining.
  • Q: I like the colour of my paving stones when they’re wet, is there a way to make them always look that colour?
    A: This is one of the main reasons we seal paving stones! Sealing will make the stones appear darker, more colourful and slightly shiny, just like they are wet! Keep in mind, sun exposure as well as some de-icing agents cause the sealant to deteriorate.
  • Q: Will the paving stone colour fade with time?
    A: Greentree’s natural paving stones have been that colour for millions of years and we are confident they will remain the same colour for at least another million. Unfortunately, concrete paving stones are susceptible to fading.
  • Q: Why does it look like some of my paving stones have broken corners?
    A: Since the paving stones are natural, we chose to offer them with a more natural, tumbled appearance. This effect is usually most noticeable on the corners.
  • Q: Will there be gaps between my paving stones?
    A: Yes, each paving stone size has an allowable margin of acceptance to create a balance between accuracy and waste reduction. Don’t worry though – this gap gets filled with polymeric sand to decrease the maintenance required and the visibility of the gap.
  • Q: Why are there large gaps between the stones in curved areas?
    A: Industry standard for gaps between square or rectangle paving stones in curved areas is ¾.” This means that the stone should be touching on one side and on the opposite; the gap should be equal to or less than ¾” and the gap should then be filled with a polymeric sand to reduce visibility and maintenance.
  • Q: I noticed weeds growing out of my patio what can I do to keep them out?
    A: We install polymeric sand between paving stones to minimize weeds growing between stones, however, while polymeric sand has some flexibility to it, it is not perfect and sometimes crack over the colder months due to frost heave. This can be fixed by buying a bag of polymeric sand then carefully filling the crack with it and using a mist bottle to lightly wet the sand. Be careful not to put too much poly-sand on as it can stick to the paving stones once it gets wet.
  • Q: Will the paving stones be above the grass?
    A: No, to make yard maintenance easier and reduce the potential for tripping, we make sure to build the base low enough that the top of the paving stone is just slightly above the base of the adjacent material.
  • Q: Will it be difficult to shovel off my paving stones?
    A: This varies greatly depending on the pattern of the stones and the direction they are installed compared to the direction you are shovelling. Everyone knows the feeling of running square into a crack: if you go at an angle to that crack, it can be almost unnoticeable, and the same goes for paving stones.
  • Q: Will my paving stones all be at the same height?
    A: As there are so many pieces to the puzzle with paving stones, it is very difficult to ensure that all of the paving stones are at the exact same height yet it is important to have a flat paving stone surface. Our standard is to have each paving stone less than 1/8” higher or lower than the adjacent paving stones.
