Benefits of an Interlocking Paver Driveway
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 7
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 7
Biaxial geogrid is installed in the base to help stabilize the aggregate adding strength to the base material.3 of 7
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.4 of 7
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.5 of 7
A jointing compound is installed in between the pavers to apply vertical interlock to the system.6 of 7
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.7 of 7
Following the excavation, we compact the subsoil to ensure our base is constructed on a stable foundation, preventing any future settling.
We lay geotextile to create a barrier separating the subsoil from the base material, guaranteeing no contamination and adding reinforcement to the base. Additionally, geogrid is employed to further enhance the stability of our base material.
12″ to 14″ of base material is installed and compacted. At least one layer of biaxial geogrid is installed in the base to help stabilize the aggregate.
The bedding layer is meticulously screeded to a maximum depth of 1.5 inches, enabling us to place our pavers on a smoother-grade material compared to the base material.
We position the pavers onto the bedding layer, and a vibratory compactor is employed to firmly embed them within the bedding layer.
We apply a jointing compound to secure vertical interlock, and a vibratory compactor aids in consolidating the material down to the joint’s base.
How We Install a Paver Driveway Project
Step #1: Preparation
When installing an interlocking stone driveway, we start with the excavation. We need to make sure that there are no underground structures that we will be hitting so every project begins with a call to Ontario One Call. They will come out and mark any utilities below the surface of the project that we will be excavating. Once we have the all clear or have the utilities marked that we need to avoid, we can begin our excavation.
Step #2: Excavation
We excavate a minimum of 12″ for the base plus an additional amount for the height of the pavers. This ensures that your base is stable and strong enough to both withstand the traffic above and the freeze-thaw cycles below. Once we have the material excavated and disposed of, we can identify your subsoil and make a decision on how we can best stabilize this soil to improve its bearing ability.
Step #3: Base Preparation
The first step in preparing the base involves compacting the subsoil, placing geotextile fabric, and installing the appropriate aggregate materials based on the chosen installation method. Additionally, we assess the potential use of geogrid at this stage. Following this, a one-inch screed layer is added to create a smooth and level surface, preparing it for the subsequent paver installation.
Step #4: Laying Pavers
The pavers are prepared for placement onto the bedding layer, and string lines can be utilized to ensure straight lines are maintained throughout the entire installation process. Once the pavers are in position, any necessary cuts can be made, and we can proceed to the next phase.
Step #5: Edge Restraint
In order to prevent any sideways shifting of the pavers, we implement the suitable edge restraint according to the selected installation technique.
Step #6: Jointing Compound
We apply the suitable jointing compound into the gaps between the pavers, ensuring it is thoroughly consolidated at the joint’s base using a vibratory compactor. This process not only secures the pavers within the bedding layer but also guarantees the vertical interlock of the pavement. This step holds significant importance in achieving a flawless final outcome for your paver project.
Step #7: Finalize
We add the finishing touches to the project, meticulously clean the area, and where needed, apply seed and topsoil to leave your property looking even better than when we initially arrived!
Frequently Asked Questions
Geotextile is a textile material employed to create a barrier, preventing any subsoil contamination while simultaneously reinforcing the base.
Woven geotextile separates, filters, and reinforces. Non-woven geotextile separates, filters, and promotes drainage. Depending on the subsoil type, we may choose to promote drainage and install non-woven or to further reinforce the base and use a woven geotextile.
Geogrid is a mesh-like roll of geosynthetic materials designed for soil stabilization purposes. Uniaxial geogrid possesses strength in a single direction and finds application in retaining wall projects, while biaxial geogrid provides strength in two directions and is typically used in paver applications.
Geogrid enhances stability by securing the aggregates within the apertures or openings of the grid system.
An Open Graded Base comprises aggregate material devoid of fines, enabling efficient water flow through the system with minimal resistance.
A Dense Graded Base contains fines within it. While it remains a material that allows for proper drainage, it has the capacity to retain moisture for more extended periods compared to an Open Graded Base.
The choice depends on the specific application. An open graded base promotes water flow due to its absence of fine materials. In contrast, a dense graded base incorporates fine materials into the aggregate. Meanwhile, a synthetic base involves the use of polypropylene sheets placed on top of a bedding layer, effectively reducing excavation depth by half.
Selecting the most suitable base material hinges on the project’s unique requirements and purpose.
Screeding involves positioning two bars at the desired height within your base material, introducing the bedding layer between these bars, and then pulling back the material to create a level surface between the bars.
No, following the screeding process, the screed bars are removed from the bedding material, and the void space they occupied is filled with the same bedding material.
We make every effort to maintain a clean job site environment. While cutting is in progress, some dust may be generated at the job site. Whenever feasible, we employ water or our dustless table saw to minimize dust and maintain cleanliness.
We utilize either polymeric sand or a semi-permeable jointing compound, and the selection depends on the base material we’ve chosen.
By compacting the pavers, they are securely embedded into the bedding layer, simultaneously consolidating the jointing compound to the joint’s base, ensuring vertical interlock within the system. Neglecting this step would result in jointing compound failure, as it would not make proper contact with the bedding layer and could eventually erode due to traffic.
Our preference is to install a concrete edge restraint, as it guarantees horizontal interlock within the system without the risk of a plastic edge restraint protruding above your pavers over time. However, in synthetic base installations, we do utilize a plastic edge restraint because it securely attaches to the base panels and eliminates the risk of heaving.
We guide you through every phase of the project! Typically, during the initial consultation, we bring samples to gauge your preferences. Following that, we design the project according to your preferences and proceed with selecting the most suitable paver. Additionally, we can arrange to meet you at a nearby supplier to further streamline the selection process and bring samples to your property for the final decision.
As a standard practice, we often implement a random pattern. Nevertheless, certain designs may necessitate a more contemporary layout, or in the case of driveway projects, a herringbone pattern might be more suitable to enhance interlock performance.
The occurrence of white staining is known as efflorescence, which is a natural outcome of concrete. It arises from moisture drawing minerals to the concrete’s surface.
If your project incorporates a base material with effective drainage, the efflorescence will gradually dissipate. Additionally, we offer a cleaning service to eliminate any remaining efflorescence.
