North Greece Landscape is proud to follow ICPI (Interlocking Concrete Pavement Institute) specifications in the installation of your project. We would like you to be informed of what should be done for the longevity of your project. In order to ensure quality installation, it is recommended to ask contractors the following questions:
How long have they been installing pavers?
We have been installing pavers for more than 12 years now. We are certified by ICPI & NCMA.
What percentage of their total business consists of installing concrete pavers?
Our paver installations are 90% of our work. We do offer plant installation but we concentrate mostly on the paver industry.
Do they install the job per ICPI guidelines?
We follow all ICPI specifications; we also exceed them in most cases.
We recommend the following for our installations:
Excavated area will be a minimum 6” wider than the actual paved area. The extra width will help ensure stability of the base at the edges, and provide space for required edge restraint.
After excavation we recommend a woven Geo-Textile fabric over clays or silts. The fabric separates fines in soils from the base and prevents them from migrating upward into the base. This will also strengthen the paved area.
ICPI recommends a minimum 8” base for our area. We use 8 inches or more depending on application. Compaction of your base should be done in lifts of 4-5”. This will ensure proper compaction of base aggregate. You must also have the proper equipment to achieve this. We use large reversible tampers that compact at 6500lbs centrifugal force.
Bedding sand is installed over the base to a consistent thickness. ICPI guidelines note that bedding sand can be installed between ¾” and 1 ½”. They also recommend concrete sand only. Concrete sand has very little fines. Stone dust is widely used locally but it has a high percentage of fines. Fines can work their way out of the bed and cause deviations and failure of your project.
Once pavers are laid they will be compacted. As the pavers are getting compacted the bedding sand is being pushed up into the joints of the pavers. This will create interlock. After all of the paved area is compacted, the polymeric sand will be applied to the joints. Polymeric sand will get hard after being activated with water. This will help reduce weeds and erosion.
As a conscientious owner, you want assurance that the contractor you hire will do quality work. It’s important that you take the time to ask questions about all aspects of your project with a qualified contractor.
We hope this information will lead you in the right direction and help you find a contractor that is going to do quality installation and craftsmanship. We hope that the contractor you use would strive to do their best. This is our industry and the work we do reflects upon us.
Thank you for giving us the opportunity to bid on your project. We would like to install and complete your project so you can enjoy it for years to come.
