How to Lay Fossil Mint Indian Sandstone Paving Slabs for a Stunning Look
Fossil Mint Indian Sandstone has quickly become one of the most requested patio stones in UK gardens, and it's easy to see why. Its pale, ivory-cream tones brighten up small courtyards and large patios alike, and the occasional fossil detailing gives every slab its own character. If you're planning a project with Fossil Mint Indian Sandstone, getting the groundwork and laying process right is what separates a patio that lasts decades from one that cracks or sinks within a few years. This guide walks you through the whole job, step by step.
Quick Answer
Fossil Mint Indian Sandstone paving is laid on a compacted MOT Type 1 sub-base, followed by a semi-dry mortar bed of roughly 5 parts sharp sand to 1 part cement. Slabs are bedded with a rubber mallet, spaced 8 to 10mm apart, and pointed once set. The whole job typically takes a weekend for an average patio, longer for larger commercial areas.
Key Takeaways
Fossil Mint is a light, pale sandstone, not actually mint green in colour
A proper sub-base and mortar bed are essential for a stable patio
Finished paving needs to sit at least 150mm below the damp-proof course
Order 10 percent extra stone to allow for cuts and natural variation
Riven, sawn, and tumbled finishes each suit different garden styles
Why Fossil Mint Indian Sandstone Is So Popular in UK Gardens
Fossil Mint Sandstone suits the British climate well because it's naturally frost resistant and copes with heavy rain without staining easily. Its light, ivory-cream shade reflects more daylight than darker stones like Kandla Grey, which makes shaded courtyards and small back gardens feel more open. Homeowners also like that no two slabs look identical, since the natural fossil markings and tonal variation give every patio a one-of-a-kind finish rather than the flat, uniform look of concrete paving.
Which Fossil Mint Paving Slabs Should You Choose?
The right slab depends on the size and style of your project. Fossil Mint Sandstone Paving comes in several formats to suit different layouts:
600 x 900mm: the most popular size, ideal for larger patios and garden paving
600 x 600mm: suited to smaller courtyards and pathways
Mixed-size patio packs: good for a traditional, random-laid pattern
600 x 1200mm: large-format slabs for commercial or contemporary schemes
Mint Sandstone Paving with a riven finish gives a traditional, textured surface with good grip underfoot, while a sawn or smooth finish suits modern patios. Tumbled Fossil Mint sandstone has a softer, weathered edge that works well for reclaimed-style gardens.
What You Need Before You Start
Before laying Fossil Mint sandstone, gather your tools and materials. You'll need a spade, wheelbarrow, spirit level, rubber mallet, string lines, a plate compactor, a pointing trowel, and a bucket and sponge for cleaning as you go. On the materials side, you'll want your sandstone slabs plus 10 percent extra for wastage, MOT Type 1 sub-base aggregate, sharp sand, cement, jointing compound, and a paving primer for the back of sawn slabs. Having everything on site before you dig saves a lot of stop-start frustration later.
How to Lay Fossil Mint Sandstone Paving Slabs Step by Step
Start by marking out the area with string lines and pegs, checking that your finished paving level sits at least 150mm below the property's damp-proof course, a rule confirmed in UK building regulations guidance. Include a drainage fall of around 1:60 away from the house.
Next, excavate to a depth that allows for 100 to 150mm of compacted sub-base, a 30 to 40mm mortar bed, and the slab thickness itself. Lay and compact the MOT Type 1 sub-base in layers using a plate compactor, checking levels regularly.
Mix your mortar bed at roughly 5 parts sharp sand to 1 part cement, kept semi-dry so it holds together without oozing water. Lay each slab onto a full bed of mortar, never spot-bedded, and tap gently into place with a rubber mallet, checking levels as you go. Leave 8 to 10mm gaps between slabs for jointing.
Once the mortar has cured, usually after 24 to 36 hours, fill the joints with a sand and cement mix or a proprietary jointing compound, then clean off any residue with a damp sponge before it dries.
Common Mistakes to Avoid
Many patio failures come down to a handful of avoidable errors. Skipping or skimping on the sub-base is the biggest cause of sunken or wobbly slabs. Spot-bedding, using dabs of mortar under the corners instead of a full bed, is another common shortcut that leads to cracked slabs under weight. Ignoring the drainage fall causes puddling and can push damp back toward the house. Finally, laying slabs straight from the crate without mixing tones from different packs can leave obvious colour blocks across the finished patio.
Summary
Laying Fossil Mint Indian Sandstone properly comes down to preparation. A solid sub-base, a proper mortar bed, correct drainage falls, and careful mixing of slabs from different packs will give you a patio that looks good and holds up for years. Rushing the groundwork is the one shortcut that always shows up later.

FAQs
What is Fossil Mint Indian Sandstone?
It's a light, pale sandstone quarried in India, known for its ivory-cream tones and occasional natural fossil detailing rather than any green colouring.
Is Fossil Mint sandstone suitable for driveways as well as patios?
Yes, in thicker calibrated formats it can handle vehicle loads, though a specifier should confirm thickness and sub-base depth for driveway use.
How thick should Fossil Mint sandstone paving be for a garden patio?
22mm calibrated is the standard thickness used for most UK garden patios and pathways.
Does Fossil Mint Sandstone Paving need sealing?
Sealing isn't compulsory, but it helps reduce staining and moss growth, especially on lighter stone where marks show more easily.
How much extra stone should I order for wastage?
Order around 10 percent extra to allow for cuts, breakages, and any slabs you want to set aside due to strong colour variation.
Can Mint Fossil Sandstone be laid in winter?
Yes, but mortar needs frost-free conditions to cure properly, so avoid laying during hard frosts or freezing temperatures.
What's the difference between riven and sawn Fossil Mint sandstone?
Riven has a natural, textured split surface with more grip, while sawn is flatter and smoother, suited to contemporary designs.
Is Fossil Mint sandstone good for small gardens?
Yes, its pale tone reflects light well, which helps smaller or shaded spaces feel more open and less enclosed.
Can I mix Fossil Mint with other Indian sandstone colours?
Yes, many UK gardens mix Fossil Mint with Rippon Buff or Kandla Grey for a layered, multi-tonal patio design.
