Common Indian Stone Paving Problems in Canada And How to Fix Them

It’s no secret that Indian sandstone is a well-liked and useful natural stone to utilize in landscaping. Indian sandstone’s wide range of color options and polish options, whether used for patios, walks, or outdoor dining, may greatly improve your garden. However, it is not without its drawbacks. The primary issues with Indian stone paving in Canada are listed here as solutions to keep your paving looking good.

Spaces Between Paving Staining Indian Sandstone

An evenly flat and spread-out mortar base is used as a foundation for the installation of Indian sandstone. Landscapers may apply mortar using the “dot and dab” technique rather than properly spreading it, leaving spaces (or “voids”) under the paving that can collect moisture or water. The sandstone paving will develop reflective staining; as result, giving it a spotty stained appearance.

How to Fix?

• Try a basic clean with soapy water and a gentle power wash before putting them up to temporarily eliminate the stains.

• Check to see if the mortar appears to have been “dot and dabbed.” If so, lay out some freshly mixed mortar evenly.

Uneven or Bumpy Sandstone From Inappropriate Placing

When Indian sandstone paving is installed incorrectly, it may eventually become uneven or bumpy. The side that will face upwards will be smoother and better finished than the underside, which can occur when some slabs are not positioned the right way up.

How to Fix?

• After giving the slab a brief jet wash, gently sponge-wash it with a diluted bleach solution, then let it air dry.

• Replace the slab into the slot with glue made specifically for natural stone, let it set, and then seal it 24 hours later.

Indian Sandstone Paving Delamination

Despite your best efforts to maintain it, Indian sandstone paving is sadly susceptible to deterioration because it is entirely natural. Even the best quality of sandstone from Indian Natural Stone Suppliers is prone to deteriorate after a certain lapse of time.

Delamination, the collective word for a natural stone’s flaking or “spalling,” is one of the weathering processes that affect Indian sandstone.

With Indian stone paving in Canada, this occurs when excessive moisture content seeps into the paving pores, causing crystallization and freezing activity that eventually weakens the paving.

How to Fix?

• Try to keep your Indian sandstone dry by avoiding harsh chemicals and frequent washing.

• A powerful water wash on Indian sandstone is a no-no. If you wash your sandstone, wash it gently because the pressure will further erode its integrity.

Red or Yellow Staining Because of Moisture Absorption

Yellow or red staining, which results from a high moisture content driving iron oxidation inside the sandstone, is one of the main issues brought on by moisture.

These iron minerals begin to soak into the sandstone when they oxidize, leaving behind noticeable colored streaks.

How to Fix?

• Gently dab hydrogen peroxide into the stains with a spare paintbrush or something similar.

• Applying sealer is another option, but it won’t be able to remove the stains. However, it will probably lessen staining in the future.


These are the typical issues with Indian stone paving in Canada and their fixes. Nearly all issues with natural stone are the result of improper installation.
