AQUAPONICS

Aquaponics refers to any system that combines conventional aquaculture with hydroponics in a symbiotic environment. The aquaponics system was started at Sacred groves to realise the ‘waste is food’ concept. To achieve a way in which the recycled grey water can be used for rearing fishes and using the same water rich in nutrition for growing food.… READ MORE...

ROOF:

The roof is made of sloping palm trusses. Palm wood is used because it is locally available. On comparison, the density of 1 sqm of teak is 900 kg/m3 and the density of 1 sqm of Palmyra is 970 kg/m3. The high density of palm also makes it difficult for termites to chew through.… READ MORE...

INTERIOR MUD PLASTERING:

The cow dung- mud plastering of the second house took a pretty long span of time for the completion although it had qualities such as better water resistance, better termite resistance, better in absorbing impacts and better antiseptic properties. Also to level the bumpy surface of the cob walls, we have to apply small quantities of the mix, layer by layer [NO CHISELLING], and that lead to a much longer time period for plastering.… READ MORE...

EXTERIOR LIME PLASTERING:

To prevent the building from direct action of rain and moisture, lime plaster is used for exterior plastering. For this plastering, lime has to be prepared in a certain specific way.

Why Lime?

Economically sustainable and it provides water resistance and breathability.… READ MORE...

LIME FLOORING:

Procedure:

Earth was rammed and then big rubbles (2-3”thk) were put. We walked on it to level it. Small gravel stones (1-1.5”thk) were then put on the bed of big rubbles.
A mixture of kadukkai and jaggery mix was then poured on to the stone base as they get soaked in it and thus become better in gelling with the flooring mix.… READ MORE...

COB FLOORING:

The area to be completed with cob flooring was backfilled up to -1ft from the expected finish level and was lined with earth-crete plinth wall.

Termite proofing:

The cob floor should be protected from termites. So as a precaution we started the flooring with a layer of Charcoal followed by a layer of Quarry Dust.… READ MORE...

CLAY STRAW WALL:

Clay straw wall is an easy to do, low cost, minimum impact and light weight wall construction technique. It does not get affected by termites because of high silica content in rice straw and it provides good insulation. It is a good acoustic and noise reduction.… READ MORE...

WATTLE AND DAUB:

We constructed wattle and daub as interior partition walls in the dorm.

Wattle and daub is a simple and very effective wall construction technique. It was often used in medieval Europe and is known for its earth-quake resistance.

WHAT IS WATTLE AND DAUB?… READ MORE...

WINDOW ARCHES:

FORM WORK METHOD:

Form work was made with waste plywood planks. The cob was then laid over in layer well interconnected again by merging to make a monolithic structure.

But in this technique, while removing the form work, the vibrations may cause the arches to develop cracks.… READ MORE...

EARTH-CRETE:

1. The materials required for earth-creting i.e., aggregates, earth and cement are loaded in the appropriate ratios into the mixer machine. Ratios used for Earthcrete mix are (Cement:Earth:Aggregates from rubble): 1:9:18, 1:6:12, ¾:5:14. The ratio is changed according to the type of Earth, size of Aggregates and the kind of structural material it goes into.… READ MORE...
