Sandstone slabs from the same pack can vary by several millimetres in thickness. Each slab is individually bedded on a mortar mix to bring the surface to a consistent level. On Cambridge clay ground, a compacted Type 1 sub-base is laid first to prevent seasonal movement from lifting or dipping individual slabs. Raj Green is the most requested colour variant, with blue-grey tones that work with both brick and render. Colour variation within a batch is normal for natural stone, and samples are available before ordering. Pricing is per square metre and covers the slab, bedding mortar, jointing compound and sub-base preparation as separate lines. Sandstone is porous and benefits from sealing after laying. Unsealed joints allow moss and algae to establish quickly, particularly through Cambridge’s damp winters. The installer rakes joints to a consistent depth and fills with a jointing compound suited to natural stone before recommending a sealer appropriate for the finish chosen.

Most Indian sandstone patio installations come in at £1,400-£2,800, depending on the area size, slab thickness, and ground preparation needed. Larger [patios](https://www.cambridgepatios.co.uk/) with complex cuts or significant base work will sit toward the top of that range. ### Is Indian sandstone a good choice for a patio? Yes, Indian sandstone is a well-established patio material. It is naturally textured, available in a wide colour range, and when laid on a properly prepared sub-base it performs well outdoors. Sealing after installation helps it resist staining and extends its lifespan. ### Is Indian sandstone suitable for outdoor use in British weather? Yes, provided it is laid correctly and sealed. Calibrated Indian sandstone at 22 mm or more, bedded on a full mortar bed over a compacted sub-base, handles British rain and frost well. Sealing closes the pores and reduces water absorption, which is the main cause of freeze-thaw damage. ### What thickness should Indian sandstone paving slabs be for a patio? 22 mm is the standard minimum for a pedestrian patio. For areas that will take vehicle access or heavy garden furniture, 30 mm slabs are more appropriate. Thinner slabs below 20 mm are more prone to cracking under point loads and are not recommended for full patio use. ### Will my Indian sandstone patio be slippery when it gets wet? A riven or textured surface finish significantly reduces slip risk when wet. Honed or polished finishes are more slippery and are better suited to covered areas. Algae build-up on an unsealed surface increases slip risk over time, which is why sealing and annual cleaning matter. ### Can I jet wash Indian sandstone? Yes, but use a wide fan nozzle at low to medium pressure, no higher than 100 bar. Keep the nozzle moving and avoid holding it close to the surface or pointing it directly at the mortar joints. A gentle annual wash is usually enough to keep the surface clean. ### Will jet washing damage Indian sandstone? High pressure or a narrow nozzle can erode the surface texture and blast out the pointing between slabs. Damage is most likely on unsealed stone or where the mortar joints are already weakened. Low pressure with a wide fan nozzle avoids this. [Repointing after damage](https://www.cambridgepatios.co.uk/services/patio-cleaning-repointing-repair) ### Will the colour and finish look the same across the patio? No, and that is a natural characteristic of sandstone. Each slab carries its own mineral variation, so tone and veining differ across the patio. This variation is part of the material’s appeal, but if you want a uniform look, porcelain is a more consistent alternative.
