Interlock Patios
Built from the ground down. A patio that stays flat, drains right and looks as sharp in ten years as it does on day one.
Every interlock patio looks the same the week it's finished. The difference shows up a few winters later, when a patio built on a thin base starts to sink, heave and grow weeds through the joints. Groundwork Landscaping builds patios from the base up: proper excavation, compacted granular in layers, a slope that sheds water away from the house and edges that hold everything in place.
What's included
- Layout and design sized for your table, chairs, barbecue and the way you'll use it.
- Excavation to the depth the base needs, with soil hauled away.
- Compacted granular base, laid and compacted in layers, not dumped in one go.
- A slight slope away from the house so water runs off.
- Pavers laid in the pattern you choose, with clean cuts at every edge.
- Edge restraint and polymeric sand to lock the pavers and resist weeds and ants.
How a patio is built
- Locate and mark. Utilities located through Ontario One Call, and the patio laid out on the ground.
- Dig and base. Excavate, lay the base in lifts and compact each one.
- Screed and lay. A level bedding layer, then pavers laid and cut to fit.
- Lock it in. Edge restraint, compaction, polymeric sand and a final clean.
Make it a destination
Add a seat wall, a fire pit or outdoor kitchen and lighting to turn a patio into an outdoor room. On a sloped yard, a retaining wall can create the flat space a patio needs.
What affects the cost of interlock patios
Patios are priced mostly by square footage and the paver you choose, from standard concrete pavers to premium and natural stone. Excavation depth, access for equipment, removing an old patio or deck, steps, seat walls, curves and complex patterns all add to the cost. A proper base is a big part of the price, and it's the last place to save money.
Interlock Patios questions
How long does an interlock patio last?
Built on a proper base, an interlock patio can last for decades. Individual pavers can be lifted and replaced if one is ever damaged.
Pavers or poured concrete?
Pavers flex with frost and can be repaired one stone at a time, while poured concrete can crack and is hard to patch invisibly. Pavers also come in many more looks.
How long does it take to build a patio?
Most residential patios take a few days to a week, depending on size, access and features like walls or steps.
What's polymeric sand?
It's a joint sand with a binder that hardens when wet. It locks the pavers together and helps keep weeds and ants out of the joints.
Can you build over my old concrete patio?
Sometimes, but usually it's better to remove it. Building on old concrete can cause drainage and height problems at the door.
What paver patterns are there?
Running bond, herringbone, basket weave and random multi-size patterns are the most common. Large-format slabs give a clean, modern look.
Should I seal my new patio?
Sealing is optional. It deepens the colour and helps resist stains, and is usually done after the first season once any efflorescence has settled.
