Emphasize a Proper Compact to Avoid Ruining Your Paver Project

August 6, 2018 Published by Leave your thoughts

Pavers can be used in a variety of different ways on your property to add some extra aesthetic value to paving projects, whether it’s for a patio, driveway or decorative area. When placing pavers, it’s important you get the job done right the first time so you don’t have to spend extra time or money redoing it. This means getting a proper compact in the sub base. A failure to properly compact the sub base could result in the pavers breaking over time.

Here are just a few of the factors that could affect your patio pavers in Brooklyn, NY if you do not get a proper compact:

  • Freezing and thawing: The regular freezing and thawing cycles can quickly wreak havoc on your concrete pavers if the ground was not properly compacted. Every tiny spot in the sub base is a place where water could settle, and as it freezes it will expand, which causes the pavers to lift up. When it thaws, the paver will settle, but probably not evenly, creating an uneven surface and a higher likelihood of breakage.
  • Foot or vehicle traffic: On a driveway, for example, any pavers that sit on top of areas that have been poorly compacted will compress and shift over time. Your car’s weight will push the paver into the weak spots, which could break the pavers.
  • Joint failure: Joint tools like polymeric sand are designed to be as flexible as possible, but they will not perform as designed if installed on top of an improperly compacted surface. The paver joints will crack due to the shifting of the pavers over time.

How to make sure you properly compact the sub base

So what can you do to ensure the sub base below your pavers gets properly compacted? Here are a few steps you should follow during your job:

  • Always make sure you have the correct base depth. For pedestrian walkways, this will be four to six inches. For driveways, it’s a bit deeper, usually eight to 12 inches.
  • Make sure you use the correct material for the base. The standard is granular coarse stone 0-3/4” (also known as “dense grade”) for the base material. For the setting bed, use concrete sand.
  • If you’re using a plate compactor for the job, don’t try to compact large areas of material all at once. About four inches at a time is your best bet. Any more than that, and you’ll likely only compact the top four inches, which means the material below that will settle.

You can find most of the materials you need at a local home goods store, or you can reach out to a team of professionals if you need assistance in correctly installing your patio pavers in Brooklyn, NY.
