5 Ways to Create a Natural Floor

12/3/2019

33 Comments

 
It’s been natural floor month in the Mud Home Facebook Group, with a number of members attacking their substrates and creating natural beauty by the spade-load. As luck would have it, all of them have chosen different flooring methods, which not only gives me fodder for a great post, but is filling my noodle with ideas. Because it’s just about floor time for my little stone cabanas in Spain. So which one of these five will I choose?

1. Earthen floor
Picture
Kim Siu’s hobbit house in Moray, built by Hartwyn Natural Building
Here’s a floor to salivate over if ever I saw one. Earthen floors can be absolutely stunning, though they require some know-how. As with most floors, earthen floors are usually laid upon compressed gravel or foam glass beds. Foam glass is popular because it adds insulation too. There is some disagreement as to whether a vapour membrane is necessary to stop moisture wicking up into the floor. If you’re in a dry climate, or with a house that’s high up a slope with plenty of drainage, you may well get away without one, if not probably best to hedge your bets. For the record Kim’s gorgeous floor (shown above) in her hobbit house in Scotland  didn’t require one, and it was built to code*.

Earthen floors are basically a cob or earth plaster mixture poured, troweled and left to dry. After this they are coated a few times in an oil (most commonly linseed). Kim’s floor above has also been polished with beeswax.

You can learn more about how to make them on The Abundant Edge podcast with earthen floor expert Sukita Reay Crimmel. She is the co author of Earthen Floors book, which I can also recommend.
 
Pros: You can create gorgeous looks with an earthen floor. And if insulation is used, they are pretty snug too.
Cons: Earthen floors are probably the least hard-wearing of all the natural floor types listed here. If not properly protected, chair legs can gouge holes out.
 
You can feast your eyes on plenty more luscious photos of the Kim Siu's amazing straw bale Hobbit House here: Kim's lovely house was built by Hartwyn Natural Building.
 
2. Limecrete
Picture

For folk needing something more durable, limecrete is used all over the world as a flooring option (much like concrete). When restoring ancient homes in the UK, limecrete floors are pretty much always installed, because they are both breathable and can handle some damp.
 
Again limecrete floors are laid on compressed beds of loose aggregate.
 
For more information on creating your own limecrete look here. Always test on a small area (2 metres squared, for example) before mixing a whole batch, as everyone’s limecrete mixes vary according to the kind of lime used, the climate, and other strange mystical forces that inevitably evade meticulous calculations.
 
This nice post by Richard CL Pillinger shows how to lay a limecrete floor. And here's a video showing how.
 
Which kind of lime should you use for floors? If you’re new to lime you’ll want to check out the Mud Home guide to various lime types. For flooring, many tradespeople prefer NHL type limes because they are more cementitious, and set harder. There are plenty of diehards who use pure lime putty too, though.
 
In some countries like the UK and Australia, ready-made limecrete slabs are also available.
 
Pros: Limecrete breathes. Lime is a natural fungicide and insecticide too, so it’s great for wet climates.
​
Cons: Lime is trickier to work with than stones, bricks or wood. You need to get your mixture right, and allow it to cure slowly but thoroughly.

Don't forget lime is caustic. Read the Mud Home guide to using lime safely here.
 
3. Simple gravel bed with stones/bricks
Picture
My first attempt around the water trough.
I’m becoming a bit of a fan of this method. For outside spaces it’s a no-brainer. So easy. So low-impact. And you can create some very aesthetic results with gravel and slabs too.
 
All you have to do is throw down a bed of gravel or sand (hard core really creates a strong base), and then inlay bricks or slabs or stones into the gravel bed. Once you’ve achieved the pattern you love, fill in the gaps around the stones by throwing more gravel or sand over the top and brushing it into the gaps. This stops your bricks/stones from shifting around and wobbling.
 
Pros: Much more stable than you’d expect. Superb for drainage as it’s completely unsealed and any water simply seeps away. Easy and cheap to make.
 
Cons: Because it’s not sealed you may find grains of sand working their way out. I’m happy to sweep the floor every now and again, but clean freaks may not be. You’ll probably need to refill the sand in the gaps every year or so.

4. Wood
Picture
Juniper floor in The Mud Home, Turkey.
I love a wooden floor. Always have, always will. They smell and feel so good. No gravel bed needed with a wooden floor. Usually (at ground level) wooden floors are raised slightly off the ground to prevent damp rotting them. They’re actually pretty easy to make, even for newbie builders (I made mine in our roundhouse in Turkey with Celal, and although it wasn’t perfect, I loved it).
 
Pros: Warm on the feet, nice on the eyes, and they smell good too. Wood floors are very hard-wearing, give you a perfectly flat platform, and are relatively easy to make.
 
Cons: Not particularly sustainable in most cases (timber isn’t unless it’s reclaimed). Wood is also notoriously expensive, and will usually result in the greatest outlay in your build.

I'll be writing a full post on creating a wooden floor for a round house at a later date, because many folk ask how I did it.
 
5. Breathable tiles with lime mortar
Picture
Emma Winfield’s perfect quarry tile floor.
Emma Winfield in our FB group created this gorgeous floor using buff-coloured quarry tiles laid into a lime mortar. The result, as you can see, is very professional. Lime mortar is essentially simple to make (usually somewhere in the region of 1 part lime to 3 parts sand) but you need to test you batch well first because everyone's ratios seem to be slightly different.

If you want to read more about lime plaster/mortar and crete, read The Mud Home post on it here
 
Pros: Very slick finish and even suitable for mainstream homes (or restoration projects).
 
Cons: You need to get your lime mortar mixture and application method right, otherwise the tiles may not stick.
 
Which Natural Floor Will I Choose?
Picture
Which floor for this one then?
​I love to experiment, and it’s lucky I have three cabanas. Because I shall be using the gravel bed with stone slabs or bricks in one, an earthen floor in another, and probably wood in the big one. But hey, you know me. Time will tell. :)

As always, terrific information and great ideas. The problem comes in when one tries to decide on what type of floor they really want -- Perhaps one could put a diamond shaped wood floor in the middle, then surround that with a tile floor and finish up the outer ring with an earthen floor. I like them all. Am in the land hunting phase and I am really excited about it. I am sure something viable will present itself to me.

For info, a slightly stronger mix is advised when making up lime mortar for tile laying (as opposed to brick laying or pointing) as it has a bit of a tougher job to do.

The mix generally recommended for tiling is 5:2 (sand:lime), and that is what we used for the terracotta floor above. We used the same strength mortar for the grouting, since in a floor it is subject to quite a lot of stress from a variety of angles, and helps retain the structural integrity of the floor.

Tiz about your bought of flu, not flooring. 😜. You might want to check on 'OREGANO OIL', for the next time you feel the flu coming on. Tiz antibacterial, antimicrobial, n antiviral, and is also effective on fighting MRSA. You can use it on scrapes n cuts also.🤔 It's carrier is olive oil, so whenever I feel a sore throat coming on, I homogenize a half a dropper full with a half tank of water in my waterpik, then fill the tank, and after cleaning my teeth, I save a mouthful and gargle a few times, I do that everyday, sometimes more than once, till the soreness goes away. Has worked every time so far. 😍😘

Excellent information just what I needed with bonus of knowing pros and cons

I am planning my own mud house walls would be of Rammed earth but I am getting more information on flooring. I want white flooring without using artificial tiles.
Can earthen flooring be of white colour without using paint?
I want mat finish not shiny stuff
White looks bright and reflects back light
So how do I get white flooring
I want same type of flooring

Hello, when you are taling abouth earthen floor on top of glass foam do you mean that between the stamped glass foam (and the eventual vapor barier) you sonore place any other strong layer for stability? Kind regards, julie

Love the posting on diff types of flooring

I am in a dilemma. Prepared lime mortar to lay but fancied unfinished granite stones. Luckily got my hands on quite a few pieces picked from a 96 yr old building which was demolished. Now looking forward to using this material. Pl suggest anything ai need to look for

Thanks for pointing out that we can create aesthetic results with gravel and slabs. As you said, they can also be great for drainage at they are unsealed. This is helpful because my husband and I are planning to have our own space where we can build a family. We are hoping to find contractors on Monday who can construct a two-story house for us within eight months.

It got me when you said that earthen floors also look gorgeous and are pretty good when insulation is used. I will keep that in mind and consider it once I have the budget for a flooring installation project next year. I just to get the old property renovated soon so that I can feel more comfortable in this house, especially when most parts of it are old after inheriting this from my grandparents.

Hi, thanks for the great article, super useful. I'm working on a small project in SW England, a small building for agricultural purposes and with a small kitchen. We would love to have an earthen floor but are a bit concerned about durability (if it gets wet near the door, or around the sink). Are there ways we can deal with this with an earthen floor? Thanks!

Limecrete, a sustainable alternative to traditional concrete, is increasingly used worldwide as a flooring option. Composed of lime instead of cement, limecrete boasts several ecological and practical benefits. It is highly breathable, reducing moisture-related issues, and has a lower carbon footprint due to lime's ability to absorb CO2 during curing. This ancient building material has seen a resurgence in modern construction, especially in eco-friendly projects and historic building renovations.
