How Failing To Compact Will Ruin Your Paver Project

If you have read some of our other blog posts, you know we’re huge advocates of “do it once and do it right.” This is because we have seen too many jobs go awry due to a step being missed during the paver installation process. This critical step is compacting the base. A proper compact will help maintain your project’s integrity,protect jointing material, and keep your outdoor patio or walkway looking sharp for a long time.

Interlocking pavers
are made to be flexible, meaning that they will move, mold and mimic to any settling or shifts in the soil or base. If they are installed over  an improperly compacted sub-base  they are not going to stand the test of time.

Not to mention there are other variables that can exacerbate the issue of paver settling and moving on an improperly compacted base,

  • Weather: Freeze/thaw cycles can wreak havoc on a paver installation that was improperly compacted. Each void within the sub-base serves as a place for water to potentially settle. When this water freezes it will expand and cause the pavers to heave; when it thaws, the pavers will settle (but likely not evenly), eventually creating an uneven surface.
  • Car on paver drivewayTraffic: Driveway pavers that sit on top of poorly compacted areas will shift and compress over time. The weight of a vehicle will depress pavers into the weak spots, resulting in unattractive (and potentially dangerous) ruts and grooves on the surface.
  • Joint Failure: While polymeric sand is designed to be self-healing and flexible, it will not perform as intended if it’s installed on an improperly compacted job. Radical shifting and movement of the pavers will eventually cause paver joints to crack and fail over time.

Uneven Pavers from improper compact base

 

As you can see the resulting compression and shifting of the pavers on an awfully compacted base will quickly lead to problems … many of which can lead to redoing the whole entire thing. So do it right the first time to avoid costly repairs in the long run.

 

 

Compact Base with Plate CompactorQuick Tips To Ensure Proper Base Compaction:

  • Have the proper base depth. The guidelines are to dig about 4 to 6 inches for pedestrian walks or patios and 8 to 12 inches for driveways.
  • Use the correct base material. It is recommended to use a granular course stone        0-3 ⁄4″, otherwise known as “dense grade” for the base and to use concrete sand as the setting bed.
  • Don’t compact material all at once. Most  plate compactors will not compact any more than 4” of base. If you try to compact 6” of base, you will only compact the top 4” and the bottom 2” will settle. It is best to compact your base in lifts of 3″ – 4″.

Breathable Siloxane Silane Sealers

Siloxane based masonry and brick sealers that are breathable and penetrate into the substrate have many advantages over other surface sealers comprised of acrylics, silicone and epoxies.

Siloxane Silane Water Repellent SealersAdvantages of Sealers:
A breathable sealer will help protect masonry and hardscape in many ways such as,

  • Resist cracking
  • Resist spalling
  • Reduce staining
  • Protects against UV damage
  • Prevents efflorescence
  • Prevent other damage related to water intrusion

Why choose a silane/siloxane blend?

Siloxane based sealers penetrate deep into the capillaries of concrete pavers and brick. The chemical bond that the siloxane and silane creates inside the microscopic pores acts as a resin. It minimizes the sizes of the capillaries so that it is smaller than a water molecule which provides the repellency.

Siloxane Silane SealersPenetration deep below the surface also means that your pavers will not lose protection if they are in a high traffic area. Sealers that sit on top on the paver can be eroded with heavy foot or vehicular traffic.

Siloxane/silane blends will also be 100% breathable. Concrete can absorb water 2 ways, from the surface and from the soil beneath it. These sealers will allow interior water to evaporate while also keeping surface water from penetrating into the paver. This is very important because sealers that do not allow the paver to breathe will trap moisture which can cause water to freeze and break the paver or brick during the colder months.

 

TLC Supply offers several professional grade detergents and breathable siloxane/silane sealers from industry leading brands such as Prosoco and Mapei. TLC also carries a wide selection of premium pavers from Techo Bloc, GenestBelgard and Cambridge Pavers.
