How Deep Should You Dig Before Laying Sandstone?
Getting the depth right is one of the most important parts. It helps prevent future movement or cracking.
Correct Depth for a Stable Base
You should dig around 150mm (6 inches) deep. This allows enough room for the sub-base, mortar, and slab thickness.
Tip: Always Check for Cables or Pipes First
Sometimes recently digging, make sure there are no covered-up channels, cables, or drainage lines underneath your planned area.
How to Prepare the Ground for Sandstone Paving?
A strong base means your paving won’t sink or wobble later. Here’s how to prep it properly.
Lay and Compact the Sub-Base Layer
Fill the dug-out area with 100mm of MOT Type 1. Level it and compact it with a plate compactor. This creates a rock-solid base for your slabs.
Add a Mortar Layer for a Strong Grip
Use a 4:1 mix of sharp sand and cement. Spread a 30–40mm mortar bed before placing each slab. Don’t lay slabs on dry sand—it won’t hold.
How to Lay Sandstone Slabs in a Straight Line?
Keeping slabs even and straight is key for a neat and professional look.
Start in a Corner and Work Outward
Begin from a fixed point like a wall or corner. Use a string line or level as a guide to keep your rows straight.
Tap Each Slab into Place Gently
Lay each slab onto the mortar and tap it gently using a rubber mallet. Check its level and slopes slightly away from the house (1:60 gradient) for drainage.
How to Space and Joint Sandstone Slabs?
Jointing doesn’t just make your paving look good it keeps it strong too.
Leave Consistent Gaps Between Slabs
Use spacers or a wooden stick to maintain 10–15mm gaps between slabs. This allows for thermal movement and easy jointing.
Fill the Gaps Between Sandstone Slabs
Once all slabs are laid and dry, brush jointing compound into the gaps or use a sand-and-cement slurry. Finish with a pointing tool for a clean look.
How Long Should Sandstone Paving Set Before Walking On It?
Timing is an important step too soon and you might ruin all your hard work.
Wait at Least 24–48 Hours
Allow at least one to two full days before walking on your slabs. If the weather is cold or wet, wait longer for the mortar to cure properly.

FAQ’s
Q1: Can I lay sandstone on just sand?
No. Sand alone isn’t stable enough. You need a compacted sub-base and mortar layer.
Q2: Should sandstone be sealed after laying?
Yes, sealing helps prevent stains, algae, and weather damage—especially in rainy areas.
Q3: Why are my sandstone slabs wobbling?
Wobbling means the base isn’t level, or the mortar didn’t bond properly. You may need to lift and relay those slabs.
Q4: Can sandstone be used for driveways?
Yes, but as it were if the pieces are thick (at the slightest 30mm) and laid on a full mortar bed with a solid sub-base.
Q5: What’s the best time of year to lay sandstone?
Spring or early harvest time is perfect to dodge solidifying climate or exceptionally hot days, which can influence the mortar.
Conclusion
With the right tools, a solid base, and careful laying, you can install sandstone paving that looks great and lasts for years. Don’t rush take your time to level each slab, space them properly, and let everything cure. Your garden, patio, or walkway will be something you’re proud of.
