Are your blocks cheaper than cement blocks?

No. The blocks are much more expensive than cement blocks. However, the contradiction is that, using them enables you build a cheaper house. A building is not just blocks. You will additionally need to raise the walls using mortar and metal rods, you may need to plaster and paint or even put tiles. Iforti blocks reduce the need for mortar, rods, plastering and painting. It is very possible to have a cheaper but solid and beautiful house with Iforti stabilized compressed interlocking bricks .

How is it possible to reduce building mortar?

Iforti blocks have male protrusions and female groves which enable them to interlock vertically and horizontally. This keeps the blocks firmly in place. This interlocking technology is also called dry bonding

How is it possible to reduce building rods?

Iforti blocks are not only very strong but are also very heavy (approx 10 kg. These are load-bearing and will handle heavy weights like roofs and even another storey understand that a brick wall or a stone wall does not need strengthening rods. Nevertheless, rods are used to chain the wall at the top so as to anchor the roof.

Why should the walls not be plastered?

This is only a recommendation because the blocks have a naturally smooth finish. Plastering is a costly option. It should be used to add design and aesthetics to the structure. Nevertheless, Iforti blocks can be coated to have a glossy finish.

What are the blocks made of?

At least 90% of Iforti blocks are made of pure, sieved sub soil. Less than 10% is made up of stabilizers and other ingredients that enhance their building properties.

How big are the blocks?

Our standard blocks are 220mm long and 115mm high. The width (wall thickness) is either 220mm or 140mm. Other sizes are available depending on the requirements such as special blocks for circular applications.

How many blocks for an average house?

Let’s say an average house is 4 bedrooms, 2 toilets, kitchen and store, parlour and dining. This house should, depending on the plan, take between 12000 and 1600 blocks of all sorts (foundation, load-bearing, partition, etc).

Can blocks be bigger?

No. Our standard 220mm block weighs 10kg. Bigger blocks will be too heavy for any bricklayer to conveniently work with.

Can the blocks be used in the rainy season?

Yes. Iforti blocks can be left in the rain without any structural deterioration. Its mortar-less technology make it possible to build in the rain.

Can the blocks be used in a wet climate (damp region)?

Yes. Iforti blocks are very water resistance. Iforti blocks can be made for damp applications like swampy areas and bridges.

What colour are the blocks?

Iforti blocks are currently limited to the natural soil colours. Blocks colours are different depending on the colour of the soil used. However, creative designers use special dyes of various colours and shades for brick decoration.

Can the blocks be used for a multi-storey building?

Yes, blocks have been tested for up to 3 storeys (without strengthening rods) for compressive loading and double storey structures for both eccentric compressive loads with simulated lateral wind loads. Results were excellent, hence recommendations. For higher storey buildings, it is necessary to have pillars and beams designed by a structural engineer. Iforti blocks can then be confidently and conveniently used as fill-ins.

How do I fit the doors and windows?

Building with Iforti blocks is just as building with any other material. You can nail, glue, concrete, fit any other material (wood, metal, plastics etc) unto the blocks.

Can I use the blocks for decking?

No, unfortunately the blocks cannot be used for decking as they are too heavy for decking. Decking is done conventionally with either cement block, concrete or well seasoned wood.

Is it faster building with Iforti bricks?

Yes. 1 bricklayer and 2 fetchers (unskilled labour) can easily lay 500 blocks in a day. That is more than 12m².

How much is a block?

Block prices range from 175 frs to 350 frs. We have a huge range of blocks of various strengths, sizes, and forms for various applications.

How many Iforti blocks will build a m² wall?

A 1m² wall will need 40 standard Iforti block.

What about transportation?

Iforti blocks are very strong and will transport to anywhere in trucks and containers.

Can the blocks be produced at my building site?

Yes. This is possible if you have easily access to sub-soil (slopping area), and a large sheltered area for block making and curing. This may be a cheaper alternative to block transportation
