Clay hollow Bricks

[ramki067]

Cost:

Material cost is lower, labor cost is higher, especially if you want to leave the bricks exposed. Labor has to make sure the brickwork looks pretty, hence will have to tie a thread and make sure the cement mortar is even between the bricks.

We completed our house in Oct 2011. So it has been about 15 months.

According to the CPRI compressive strength reports for porotherm brick, it is deem safe for G+1. Porotherm also mentions that it is safe for G+1. My house has longer spans hence I do employ semi-pillared construction. the structural elements were the same for normal brick work. I have planned only for G+1 and have no plans of constructing more than G+1. No fan of constructing more floors for rental income.

What is it that is driving you towards Porotherm?

In my case it was.
1. looks - I like natural brick & tiled roof, look on buildings
2. Environmentally better than regular bricks - Since they use 20% fly ash and are hollow, they use less top soil, which is precious.
3. Cooler buildings due to hollow bricks.
4. The redbricks do not have consistency. The bricks at the bottom are burnt more, while those at the top are burnt less. So the strenght of the brick varies in a given lot, while these bricks are produced using modern machines, have consistency. So each brick has more or less the same physical properties.

Hi tvsh,

I've finalized to build a room on the 2nd Floor of our old house using Porotherm blocks (K blocks as mentioned by my mestri:)). Hence, wanted to know there durability and how it is performing now as you have finished construction of you house in 2011. Do you need any maintainence with these blocks?
Also, which is the porotherm/hollow clay blocks you have used? Which is the best hollow clay blocks to go for?
Kindly bear with me with so many questions

Thanks,
Ramki

Thanks Raghu,

One of my relative built G+2 house (A room 10x12 in 2nd floor) with only 2 pillers & they have used wienerberger blocks (Vertically mounted) in major portion of the house & rest using burnt bricks & also some parts they even plastered for pleasent look. This was around 2years back when wienerberger was in startup phase & price was about Rs 35-38 for each block.

Hi Santro,

Could you please tell you experience about the Wienerberger vertically mounted bricks that you relative has built with? How is it performing now? Any issues? Please enlighten me regarding all these as i'm about to decide on using hollow clay bricks or not.

Thanks,
Ramki

I have seen Porotherm usage in a Salarpuria Magnifica which is atleast 18+ floors. I also saw it in a commercial building which was 3 floors. I guess use of Porotherm bricks is increasing now.

Guys, which is the best place to buy Clay hollow blocks in Bangalore? I am looking for load bearing clay hollow blocks of 16*8*8 size. Could anyone let me know the cost of the same

The Prices i believe are on the rise. the latest prices are in the range of Rs 60-70/- for Wienerberger. Has anyone here recently used it or got a quote from a dealer? If yes, can you please let me know some contacts and a ballpark figure?
thanks.

Today i spoke to one of the representatives from wienerberger.in, his number is 9591225217 and name is Dileep.
Here is the brief of our call

Porotherm bricks comes in 3 sizes as explained on their website
External and internal walls can be constructed using them
For external walls, plastering is must. Internal walls may or may not have plastering
If Porotherm is used, it reduces the cost of steel, cement etc to 8 to 12% as it is light weight and non load bearing.
The representative is ready to clarify any doubts with structural engineer, architect, contractor
They will also send people to help worker expertise building these walls and do site visit to check the progress.

Hi Ravi,

Did you get any quotes from him. I would be completing my stilt floor roof next week and need to quickly decide on which 6" bricks i will be using.

I enquired at Anjeneya Bricks near Whitefield as suggested by somebody on this forum and got the attached quotation. 6 by 8 by 16 is approx Rs 60. If i am not saving too much when compared to weinerberger, i might as well go for the branded one.

regards.

After posting this i just spoke to dileep from wienerberger and he said he will deliver 6 by 8 by 16 for Rs 15 per piece. I am not sure what i am missing.

[biddappa_c_b]

if u r getting 16*8*6 hollow clay blocks for Rs 15 per piece ( i presume it is non load bearing, wienerberger does not have load bearing clay hollow blocks) from wienerberger there is something seriously wrong. It is impossible for get any kind of clay hollow blocks size 16*8*6. Please do let me know if it is really 15 Rs per piece, i too would buy it immediately. Please keep us all posted.

I am soo sorry. I meant Rs 50. Busy day at office.

Still cheaper than those by Anjeneya and that is what I am surprised.
