Benefits of Interlocking Concrete Pavement

Interlocking stone stands out as a robust and low-maintenance choice for your outdoor area. Comprised of interlocking concrete pavers, it’s engineered to brave the elements, thwarting shifting or settling. In comparison to materials like wood or natural stone, interlocking stones demand considerably less upkeep. Furthermore, their versatility allows seamless customization to harmonize with any design style. We excel at installing interlocking stones, natural stone, or porcelain for a range of outdoor features, including driveways, walkways, patios, and pool decks.

Cross-Section of an Interlock Project

Compacting the subsoil ensures we are building on top of a firm foundation that will not settle.

1 of 6

Geotextile separates the subsoil from the base material so that there is no contamination between the two and to provide stabilization especially when paired with geogrid.

2 of 6

We install and compact 6″ to 8″ of 3/4″ angular crushed clean stone for our base material. This stone has no fines in it allowing water to move freely through the system without being held thus preventing freeze-thaw cycles.

3 of 6

On top of the base material is a bedding layer that does not exceed 1.5″ to level the base material and allow the pavers to be set into the base material.

4 of 6

A jointing compound is installed in between the pavers to apply vertical interlock to the system.

5 of 6

Pavers are laid on top of the bedding layer and later compacted into the bedding layer along with the jointing compound to lock the system in place.

After the excavation, we compact the subsoil so that we are building our base on a foundation that is not going to settle.

Geotextile is laid to separate the subsoil from the base material to ensure no contamination and reinforce the base material. Geogrid is also used to help stabilize our base material.

The base material is installed and compacted. The depth depends on the project. For patios and walkways we install a 6″ to 8″ base and for driveways we install a 12″ to 14″ base.

The bedding layer is screeded at no greater than 1.5″. This allows us to lay our pavers on a finer grade material than the base material.

Pavers are laid on the bedding layer and a vibratory compactor is used to seat them into the bedding layer.

A jointing compound is installed to ensure vertical interlock. A vibratory compactor helps consolidate the material to the bottom of the joint.

How We Install a Paver Project

Step #1: Preparation

Our process initiates with a thorough property survey, assessing the feasibility of laying pavers on the current grade. We evaluate whether a retaining wall or raised patio is necessary to establish a functional space. Following this assessment, we mark out the designated area to determine the patio or walkway’s elevation relative to the existing grade.

Step #2: Excavation

The depth of our excavation is determined by the established benchmarks during our preparation phase. We calculate the excavation depth by adding the height of the paver, bedding layer, and depth of base that is suitable for the project. We emphasize the importance of ensuring the excavation remains consistent with the slope intended for the top of the patio. This ensures proper water drainage away from the foundation.

Step #3: Base Preparation

The initial phase of base preparation commences by compacting the subsoil, laying down geotextile fabric, and building up with suitable aggregate materials according to the chosen installation method. Optionally, the inclusion of geogrid is considered during this phase. Subsequently, a one-inch screed layer is applied to achieve a level surface, ready for the installation of the pavers.

Step #4: Laying Pavers

Pavers are ready to be laid on top of the bedding layer. String lines can be employed to maintain straight lines during the entire laying process. Once the pavers are laid we can finish any cuts that need to be completed and move on to the next step.

Step #5: Edge Restraint

To prevent lateral movement of the pavers, we install the appropriate edge restraint based on the chosen installation method.

Step #6: Jointing Compound

The appropriate jointing compound is installed into the joints of the pavers by consolidating it to the bottom of the joint with a vibratory compactor. This also seats the pavers in to the bedding layer ensuring vertical interlock of the pavement. This step is crucial to achieving a flawless final result for your paver project.

Step #7: Finalize

Any final touches are added to the project, we clean the area, add seed and topsoil where necessary and ensure your property looks better than when we got there!

Frequently Asked Questions

For paver patios and walkways we dig 10″ to 12″. This is the depth of the base, bedding layer, and paver height. For driveways we dig an additional 6″ to 8″ more for additional base depth.

For paver patios and walkways we prepare a 6″ to 8″ base. For paver driveways we prepare a 12″ to 14″ base. This excludes the 1″ bedding layer.

Geotextile is a fabric that is used to separate the subsoil from the base material so that there is no contamination while also reinforcing the base.

Woven geotextile promotes separation, filtration, and reinforcement. Non-woven geotextile promotes separation, filtration, and drainage. So when we feel we need reinforcement we will opt for woven and when we feel we need better drainage we will opt for non-woven.

Geogrid is grid-like roll of geosynthetic materials that is used to stabilize soil. Uniaxial geogrid has strength in one direction and is used in retaining wall applications while biaxial geogrid has strength in two directions and is used in paver applications.

Geogrid stabilizes the aggregates by locking them in the apertures or holes of the grid system.

Open Graded Base consists of aggregate material that is clear of fines. This allows the water to flow through the system with minimal friction.

Dense Graded Base has fines in it. It is still a free-draining material, but it will hold onto moisture for longer periods of time than Open Graded Base.

Synthetic Base consists of polypropylene panels that are placed on top of a bedding layer. This reduces the excavation depth by half, saving time and money on the excavation phase of the project. These panels insulate your base and spread the load out over a wider area.

That depends on the application. An open graded base allows for the flow of water because the aggregate is clear of fine materials. A dense graded base has fine material mixed with the aggregate. A synthetic base consists of polypropylene sheets that are installed on top of a bedding layer which cuts the excavation depth in half.

Choosing the best base material to use depends on the application of the project.

Screeding is the act of placing two bars at the intended height in your base material, placing the bedding layer between these pipes, and pulling back the material so that there is an even surface between the pipes.

No, the screed bars are pulled out of the bedding material after screeding and the void space they were in is filled with the same bedding material.

We do our best to keep our job sites as clean as possible. During the cutting phase, the job site will be dusty. When possible, we cut using water to keep the dust down or with our dustless table saw.

We use either polymeric sand or a semi-permeable jointing compound. This depends on our base material choice.

Compacting the pavers seats them into the bedding layer while also consolidating the jointing compound to the bottom of the joint providing the system with vertical interlock. Failure to do so will cause the failure of the jointing compound as it will not meet the bedding layer and will eventually erode with traffic.

We choose to install a concrete edge restraint. This ensures horizontal interlock of the system without having a plastic edge restraint eventually heaving above your pavers. We do use a plastic edge restraint for synthetic base installations because it attaches itself directly to the base panels and will not heave.

We help you every step of the way! Typically we bring samples on the initial consultation to get a feel for your tastes. Then we design the project to your liking and continue the process of choosing the right paver. We will also meet you at a local supplier to further narrow this selection down and bring samples to your property to finalize the decision.

We typically install a random pattern. However, some designs call for a more modern pattern or a driveway application works best with a herringbone pattern to provide better interlock.

Yes. We install our paver patios and walkways on a 1/8″ (1%) per foot to 1/4″ (2%) per foot slope. This allows the water on the surface to drain off and away from your foundation.

Choosing the slope depends on the amount of sunlight your project receives and the texture of your paver. If your paver has an aggressive texture or the project receives little sun, we may opt for a 1/4″ per foot slope to ensure that water runs off.

The white staining is called efflorescence. This is a natural by-product of concrete. It is caused by moisture pulling minerals to the surface of the concrete.

If your project is installed with a properly draining material for the base, the efflorescence will eventually disappear. We do have a cleaning service to remove the efflorescence.
