Kandla Grey Umbra Sandstone Walling

If you're looking for a classic-looking wall around your garden or property, look no further than our Natural Stone Walling in a lovely grey colour.

Umbra Sandstone, traditionally known as Kandla Grey, is our best-selling Sandstone Paving, as well as Garden Walling. Grey is a highly popular colour currently, with many other garden features being grey in colour, for a timeless yet modern-looking garden. 

All of our Sandstone and Limestone Walling is sourced ethically, directly from India, meaning we offer our Sandstone Walling direct to customers, so we are able to pass on the best landscaping savings. 

As this natural stone is derived from India, it obtains features such as being naturally permeable and able to absorb some water, such as rain water. This can be great for properties that don't have as much drainage available, as it will help prevent standing/running water. 

As mentioned earlier, one of the reasons this Sandstone Walling is so popular is because of its sought-after grey colour. As this is natural stone that has been cut from larger stones found in India, the colours will naturally vary, and no two walling pieces will look the same. This is great because is means your walling will have a very natural-looking colour variance throughout, with many different shades of grey. 

These garden walling pieces are pitch-faced and have been hand-cut from larger pieces of stone within the Indian quarries. This means that whilst the edges are fairly smooth and regimented, the surface of the walling will vary in texture as well as thickness and have a lovely tumbled look to it. 

Umbra Kandla Grey Walling for Your Garden

If you're looking for an exterior wall to fence off your garden, Umbra Sandstone Walling could be a great choice. When installed properly, this Natural Stone Walling will stand the test of time against most extreme weather conditions. In contrast to a wooden fence, this walling will not weather as visibly as wood, and shouldn't need replacing for years to come. 

This Kandla Grey Walling is also highly versatile for any sized wall you're after. If you want to create a low-level wall perhaps to separate two parts of the garden that are on different levels, you have complete flexibility over the height of your natural stone wall. 

Another great use for a low-level stone wall is using it as a retaining plant bed for your borders. Adding plants to your garden that are raised from the ground is a great way of adding multi-level colour to your garden as well as making them easier to tend to and less likely to be ravaged by animals. 

Additionally to this, you can also add this Sandstone Walling to your front garden to add some privacy to the front of your home. This could be added as a stone fence with a convenient gate within the wall for properties with a larger front garden or driveway.

How to Build a Stone Wall  

Once you've purchased your Sandstone Walling, you may want to have a look at your individual pieces and sort them out in terms of size and colour variations, so you are fully prepared for placing your walling pieces. 

Ensure you have a sturdy and stable foundation for the base of your stone wall. As a general rule of thumb, the width of your foundation should be three times the width of your desired wall. For walls between 650mm and 1500mm in height, a standard, concrete foundation should work well. 

We would recommend digging your foundation to a 300mm depth, ensuring that this is within a firm soil as opposed to loose topsoil. Once the foundation is complete, allow to fully cure before building your wall on top of it. 

When your foundation is ready, create a mortar mix to start laying your stone walling in a brick fashion. For this mortar mix, use the ratio 1:5 or 1:6 of Cement : Building Sand. Combine this while gradually adding water until you reach the desired consistency. 

Using a string line and chalk, mark the position you'd like the wall to be in. You can then start to set out some of your walling pieces in place.

Lay a bed of mortar along the chalk line on the foundation; enough to fit four or five walling pieces. Once you've laid your first walling piece, take your next piece and apply the mortar mix to the end, to create the joint between the first two pieces. 

Use a rubber mallet to tap the pieces down and ensure you're checking the levels with the spirit level. Repeat horizontally until you reach the end of the first walling layer, and if you're happy with it, continue upwards.
