These are simply readable books with detailed review on Masonry wall systems: Compressed stabilized mud block, Adobe and Super adobe (Earth bag). Each of these provides some fascinating history, reviews the building system, covers general requirements, addresses cost, and summarizes the advantages and disadvantage of that building system. In general it is very well researched and highly useful directory on Masonry wall systems.

Natural Building includes variety of wall construction techniques which are typically drawn from old traditional methods of shelter making. These techniques differ from place to place, depending on the availability of materials and its response to moderate and extreme climate. It emphasizes the use of locally available materials, practices which sensitive towards mother earth. They blend with the natural and cultural surroundings and focus on skills and resources that are locally sourced and economically viable. These walls create micro-climates inside them to provide high thermal comfort levels, thus a healing effect on one’s mind, soul and health. In addition to it, the earthen wall also displays a dramatic variation in terms of textures and colours.

Mud homes withstanding floods

Please scroll below for Tamil, Malayalam and Hindi translation.

After continuous queries and doubts from many people regarding the stability of a mud building (stabilized without Cement) during high rainfall or flooding situation, we present here a video of what happened during flooding in our project Earikarai Cob Home, Anandavanam, Tiruvannamalai in December 2017. We had 4 feet high water level for 3 days. Also we have given design techniques to increase stability of Mud homes in heavy rainfall areas.

மண் கட்டிடங்களின் (சிமெண்ட்டால் நிலைப்படுத்தப்படாத) மழை அல்லது வெள்ளம் தாங்கும் உறுதியை சந்தேகிக்கும் பல கேள்விகளுக்கு பதிலளிக்குமாறு, டிசம்பர் 2017இல் நடந்த வெள்ளத்தின் போது தமிழ்நாடு திருவண்ணாமலையிலுள்ள ஏரிக்கரை ஆனந்தவனத்தின் மண் கட்டுமானத்திற்கு என்ன நிகழ்ந்தது என இக்காணொளியில் காணலாம்.மூன்று நாட்களாக நாலு அடி உயரத்திற்கு மழை நீர் வெள்ளப்பெருக்காக ஓடிக்கொண்டிருந்தது. கனத்த மழை பகுதிகளில், மண் கட்டுமானங்களின் உறுதியை மேம்படுத்தும் நுட்பங்களும் இதில் காணலாம்.

കനത്ത മഴ, വെള്ളപ്പൊക്കം തുടങ്ങിയ സാഹചര്യങ്ങളില്‍ മണ്‍വീടുകളുടെ(സിമന്റില്ലാതെ നിര്‍മ്മിച്ച) ഉറപ്പിനെയും വിശ്വാസ്യതയെയുംക്കുറിച്ചുള്ള നിരന്തരമായ അന്വേഷണങ്ങള്‍ക്കും സംശങ്ങള്‍ക്കുമൊടുവില്‍, 2017 ഡിസംബറില്‍ തിരുവണ്ണാമല, ആനന്ദവനത്തിലെ ഏരിക്കരയിലെ മണ്‍വീടിന് വെള്ളപ്പൊക്കത്തില്‍ സംഭവിച്ചതെന്താണെന്ന് ഞങ്ങളുടെ ഈ വീഡിയോ നിങ്ങളോട് സംസാരിക്കുന്നു. ഇവിടെ മൂന്ന് ദിവസം നാലടിയോളം വെള്ളം കെട്ടിനിന്നു. കനത്തമഴയില്‍ മണ്‍വീടുകള്‍ക്ക് കുടുതല്‍ കരുത്ത് നല്‍കാനുള്ള രൂപകല്പനയിലെ ചില തന്ത്രങ്ങളും ഇവിടെ പരിചയപ്പെടാം.

बिना सीमेंट की मिलावट वाले मिट्टी के घर तेज़ बारिश और बाढ़ जैसी परिस्थितियों में कितने स्थिर और कारगर हैं, ये सवाल हमसे कई बार पूछा गया है।
दिसम्बर 2017 मैं तेज़ बारिश और बाढ़ के कारण पानी का स्तर 3 दिन तक 4 फ़ीट जितना बढ़ गया था। इस वीडियो में आप देखिए की हमारे एक ऐसे मिट्टी के घर के साथ क्या हुआ।

As part of Laurie Baker’s Birth Centenary Exhibition, Thannal have attempted to reach common man through portraying different dimensions in which we try to spread awareness about Natural Buildings. Go through this brief compilation of the journey of Thannal in the past seven years to know about us more. This can also serve as an introduction of us (before a conversation with us) and the work we do, which can always give you a better idea of how you can be a part of Natural Building Movement in India and start to trace your own roots of indigenous shelter making.

If we draw insights from the composition of a human body and Natural Buildings, Plasters are the outermost skin of a building. They help to protect our buildings from various external entities like temperature and moisture (like the skin do). They impart an aesthetic language and dictates identity into a space as it is the outermost layer visible. The use of mud plasters maintains the breathing quality of the wall made of natural materials, enhancing the thermal comfort by keeping habitable temperatures inside. During summers, they remain cooler and during winters, warmth of mud can be experience.
The beauty of Indian plasters is that it utilises different natural derivatives from trees and herbs to increase the molecular strength, termite resistance and water repelling quality. Kitchen ingredients like Methi (fenugreek), Gur (jaggery), Kadukkai (Haritaki), Gooseberry, herbs like Aloe Vera, Cactus, Gums from Acacia (Arabic gum) and starch from rice, tapioca, wheat etc. are used. Animal derivatives like egg whites, animal hair, tallow, cow urine and cow dung are also crucial admixtures in plaster. Different types of mud and natural pigments like vegetable and mineral dyes helps in colouring walls through plasters. With the right recipe and simple preparation techniques, plasters can beautify the walls of any common man. The finishing layer can be of various textures depending on the technique used. Few exceptions like Thappi, Araish and Chettinad plasters requires skill and practice to execute and takes time to attain the elegant finish they offer.

Indian Plasters can be categorised into three for simple understanding.

Mud and Lime Plaster
Herbal Lime Plaster
Thappi and Araish Plaster

Thannal Natural Building School takes a watchful step to contribute to Heritage Conservation of India through a Revival Workshop on Thappi and Araish Plaster. After years of research and hands-on learning of Thappi Plaster and Lime Flooring from master mason Dawood Ibrahim Muwal in our projects, we reached the milestone to start a course for all.

Thappi is the indigenous wooden tool of Lime application, used in plastering walls and flooring methods native to Rajasthan. After a levelling coat of mud or lime crete or aggregates, a coat of Lime and Surkhi is applied and beaten by using Thappi to facilitate setting of lime. It increases the clipping of lime with wall and repairs the cracks which forms as the lime dries. It is very careful procedure done till the lime hardens. It is finished with Fine coat of Lohi or Araish (both of Lime) on top.

Lohi is quick and simple finishing method, whereas Araish is a slow, detailed method having elegant finish with colours. Through this workshop we attempt to revive this traditional method of plastering and flooring, which is time-tested and proven powerful enough through our mud water tanks. We testify to how sand can be avoided (rare and very expensive now), replacing it with Surkhi in contemporary scenario. How to make home-made Surkhi and use natural polymers like methi (fenugreek), gur (jaggery) etc will also be taught in this course.

Sardarshaher is a small town in the heart of Thar desert in Rajasthan, which is gifted with many brilliant lime artisans. It has a number of buildings done in pure Lime plasters like Lohi, Zikki and Araish. This course will be headed by master masons Dawood Ibrahim Muwal and Abdul Razak Muwal, who have worked with Lime for more than four-decades, on conservation as well as contemporary projects. Thannal seeks to revive the glory of Thappi and Araish, adorned the walls of many Haveli and honor talented traditional lime artisans of Rajasthan.

The course duration is 4 days. It will be held in Sardarshaher, Churu District, Rajasthan.
Dates: 10th, 11th, 12th, 13th May 2018.

Thannal introduces Indian Natural Plasters which are fine finishes for walls constituent of different types of mud, lime, surkhi, cow dung, herbs, natural gums, fibres and oils. It provides comfortable indoor temperature without intoxicating and degrading the space for living. It can be applied on both Natural and Conventional buildings.

Course involves two Earth Plasters, two Earth and Lime Plaster and one pure Lime plaster which can be used for both Exterior & Interior as per building design. These simple plasters do not require highly skilled artisans but workers aware about the sequence of procedure. Group of three participants will be provided with an area of 50 ft2 on Earthen walls to do base correction coat, first coat & final coat. Methods to get different textures on walls and prototype of Lime and Mud Paints will also be explained. What to do and not to do for long life of Natural Plasters will also be covered in the course. Kindly fill the form in below link to be a part of the workshop.
