Choosing the right pavers for your project
There are several factors to consider before choosing a paver for your next outdoor project.
Most importantly you need to consider, what is my budget?
Why is this important you may ask?
Well Generally, the larger the paver format, the more expensive it is going to be to buy and also to have it installed. Some pavers also require sealing to keep them looking great and protect them from the elements which will become an added expense straight after installation.
Getting some installation quotes before buying your pavers is advised, you don’t want to get stuck out not being able to afford a quality installation. Speaking to a professional installer beforehand can also be a great way to get advice on products and some different ideas of what may look great in your outdoor space.
Once the budget has been decided on, the next things you need to consider are the area to be paved and the slope of the ground.
The area and slope affect the size, depth and even the paver type you need to choose.
Paving a driveway in Perth
A flat driveway can easily be paved in large format driveway pavers while a driveway with a large slope is better suited to small format pavers as small format paving accommodates slope changes much easier than larger format paving, large format pavers may need brake lines cut across pavers to accommodate these slope changes which can be unsightly but necessary to avoid lipping.
Driveway pavers need to be of greater depth than pavers for pedestrian areas such as alfresco or pool areas. Generally, 60mm in depth for a driveway compared to 40mm for foot traffic areas therefore are slightly more expensive than the same paver type for a pedestrian area.
Pool Paving Perth
When paving a pool area, It’s important to understand that pavers made from different materials react differently to heat or chemicals such as chlorine or salt. When soft limestone products such as natural limestone or travertine are used around pool areas, especially salt water pools, it is critical they are sealed with a consolidating, penetrating sealer to protect from salt attack.
The most important area to protect from these chemicals is the splash zone around a pool, this is one of the reasons why it’s so important to have your pool coping installed by a professional. The pool coping, (or bullnose) as it’s commonly called requires an installation process most brick paving installers simply don’t do, which will result in the capping de-bonding from the pool edge.
Wet-laid vs dry laid paving.
What is dry laid paving?
Dry laid paving is the common way of installing segmental paving.
The process is essentially laying the pavers on a bed or prepared sand which then has the joints between the pavers grouted with sand. Mortar edge restraints are installed to the paving edges and a vibrating plate compactor is then run across the pavers to bed them in and lock in the paving giving it the strength to act as one unit.
Pros of dry-laid paving
- Cheaper to install
- Suited to small format paving types
- Faster to install
- Easier to repair when a problem occurs
- Fewer drainage problems
Cons of dry-laid paving
- Problems with ants and weeds
- Not as suited to some large format paving
- Not suited to natural stones when used as a driveway
What is wet laid paving?
Wet-laid paving is a process of sticking down paving to a properly prepared concrete slab base.
The slab should be a reinforced concrete slab with expansion joints placed at the correct predetermined intervals and isolation joints against any structure.
The paving stones are stuck down either direct stick with the correct tile adhesive or on a mortar bed with a bonding slurry primer.
Pros of wet laid paving (if done correctly)
- Suited to natural stone and large format paving
- Lasts a long time
- No problems with ants and weeds
- Suited to high traffic areas
- Expensive to lay
- Drainage needs to be taken into account
- Expensive to repair
- Harder to accommodate changes in slope
- Slower installation
Which process is right for me?
Basically, it comes down to your budget and the paver choice
Small format pavers are designed to be dry laid and large format natural stone pavers are designed to be wet laid. So when deciding on a paver, the cost of the paver and the installation process needs to be taken into account.
What happens if I dry lay large format paving?
As a general rule, the larger the paver format the more likely you are to have to drum underneath the paver or sinking corners. Drumming is movement underneath the pavers from the paving, not bedding and locking in properly. The larger the paver, the more likely this is to occur, which is why we recommend wet laying large pavers.
This doesn’t mean you can’t dry lay large format paving, many customers have it done, it just simply means it won’t last as long before needing maintenance.
