The Easiest Guide: How To Install Flagstone Patio

Install flagstone patio can add timeless charm and functionality to any outdoor space. Installing one yourself is a rewarding way to enhance your yard with a durable and beautiful design. This guide will walk you through the steps to install flagstone patio like a pro.

Planning & Design Before Install Flagstone Patio

• When installing flagstone, consider the space and shape.
• Sketch the patio or path beforehand to get an idea of the overall design and placement in your yard.
• Use the sketch to map out the space in the yard using a measuring tape and marking paint.
• Flagstone is often irregular making it difficult to get the surface 100% level so it’s important to choose a space in your yard that is as flat as possible sloped away from the home for drainage.
• Write down exact measurements on your sketch. Multiply your patio width by the patio length to get the size in square feet.
• Do a quick estimate of flagstone required based on the square feet and size of stone.
• Determine the amount of landscaping materials required to install flagstone patio. We recommend at least 4- 5 inches of compacted road crush depending on the weight of your stone.

Rockland Landscaping Supplies has a Materials Volume Calculator and knowledgeable staff to help you determine the required amount of landscaping supplies.

Excavation & Preparation

• Before digging, always remember to contact the utility company serving you in the Edmonton Area to ensure it’s safe.
• Remove sod, old concrete and/or soil using a spade/shovel and wheelbarrow to haul away debris.
• To estimate the correct depth for excavation, consider the width of the flagstone, 4-5 inches for the road crush base, 2 inches for sand and the slope.
• Use your measuring tape frequently to check the depth against the desired height of the flagstone surface marked by your mason’s string.
• Once you have reached the right depth, base preparation can begin.
• Apply 2 inches of road crush at a time and spread evenly in the excavation site using a rake.
• Use a plate tamper and a fine spray of water to compact the road crush into a solid base.
• Repeat the last 2 steps until you have achieved uniformity right to the edges and proper elevation.

Install Flagstone Patio

• Spread 2 inches of sand evenly over the solid foundation using a rake. Consider using levelling bars to help you achieve the right depth and appropriate drainage.
• Use a 2”X4” or a screed board to smooth and level the surface. If you’re using levelling bars, remove the poles carefully and fill in the gaps with sand and a trowel leveling off as you go.
• Avoid working yourself into a corner or walking on the sand layer.
• NOTE: Flagstones can be very heavy so take care when placing stones. You may need a dolly to transport the flagstones.
• Due to the irregular shape of flagstone, dry fit a few stones by laying them out on the grass to ensure you have the proper shapes and sizes for each section of your patio or pathway.
• If smaller stones are required, mark the stone at your desired fracture point and carefully hammer the stone for a clean break. Or allow the stone to self-fracture by allowing it to fall gently on a hard surface.
• Start placing flagstones in the desired pattern from the corner working your way in.
• Install flagstones by wiggling and pressing them into place keeping the gaps consistent and as close together as possible.
• Use a hand tamper or rubber mallet to secure the flagstone in the sand base.
• Use mason’s string as a marker and a level to ensure your stones are as level as possible removing or adding sand underneath the stone as needed.
• Use a hand tamper to go over the entire stone surface working your way from the outside edge inwards to ensure all stones are firmly in place.

Flagstone Patio Installation Completion

• Spread masonry sand over the flagstone using a hard bristle push broom to fill gaps.
• Spray with water and repeat the above step until all cracks are completely full and flush with the stone surface.
• Sweep off excess sand.
• Use sand on the outer edge to blend seamlessly into grass or garden area or consider using edge restraints or edging stones to create a finished look.
• Pro tip: Apply a stone sealer to protect and preserve the natural colour of the stones against the damaging effects from the environment.
