Frequently Asked Questions

What is the most popular Koto system?

Koto 8 because it can be installed practically anywhere and complies with any building code.

The Koto 8 system is a series of flexible versatile light-weight insulated composite forms for foundations, walls, floors and roofs from single level to multi-level buildings in either normal conditions or seismic and high-wind-speed regions, all conforming to code.

Can I build high-Rise with Koto system?
Basic rule of thumb is Koto 8 is ideal up to 7 levels. Anywhere after that the structure converts to a mix n match system whereby column & beam are used and the Koto 8 panels become the infill panels thereby reducing dead load weight.
If Koto 8 is a series of Flexible Forms, are there standards sizes that allows me flexibility of design in modules?
Yes correct, standard modules are available in both “Horizontal and Vertical” Forms for easy design, flexibility and simple installation - all with excellent energy efficiency.
How long have Koto products been tested in the market place under various weather conditions?
Since 1974 and no complaints from any customer.
Do termites damage the substrate like wood?
There is No Nutriment for termites in the Koto system. We specify two procedures that prohibit termite entry.
  • All plastic plumbing to have a super fine stainless steel mesh inserted over the plastic pipe and secured with a stainless steelhose clamp and tightened before pouring concrete.
  • When the slab is poured the perimeter footpath to the building will be included monolithically during concrete placement.
  • These two simple measures prohibit termite entry without using chemicals.
These look like up-market housing, not Low Cost/Affordable homes– How do they compete against Conventional Construction?

To date they have competed very well, with good finishes, in South East Asia or Africa. They are fast to install and look similar to any other normal monolithic masonry home on the planet.

Customers tell us they are refreshing in design and provide the occupants with a higher standard of comfort compared to conventional construction.

When installed in developed countries where labour is high, the Koto system is a developers dream.

At Koto, we believe just because some homes or mass housing is tagged as low cost housing or affordable housing, doesn’t mean to say they should look like low cost or poorly constructed, therefore with Koto materials and smart designs we can contribute to improving the construction industry in any country. This is truly one of the incredible benefits that are available using any of the Koto energy efficient IBS systems – whereas the only difference between markets is the finish.

Could a Koto home be transported ?
Yes, all Koto structural panels, and the ancillary joint materials will fit into one 40ft container/truck.
Can I tile directly onto the Koto Wall Panels in the kitchen and wet areas?
Yes, you can tile directly onto the fibre Koto composite material.
Can I apply my own architectural finishes, textures, or granite and marble over the pre-finished Koto Panels?
Yes, you can use practically any finish over the pre-coated composite Koto Panel Forms. The building system still remains the same no matter what the finish to suit any individual needs.
What are the fire ratings for the material used in Koto 8 Panels?
We have many options for fire protection whereby some panels are 2 hour fire resistant rated, others achieve ratings in accordance to Code.
What is the fire rating for your high-rise construction partition walling?
Minimum 2 hours.
Is the Koto system water tight?
Definitely. All Koto Panel Forms should be installed in accordance to specification.
What if I choose not to use the K-Pod foundation system – can I still purchase other Koto components?
Yes you can use conventional raft slab methods however, the K-Pod foundation is a system that engineers prefer as it prohibits cheating and is a network of beams connected to a thickened edge beam.

Developers like it because it is a known cost.

What is the life span of the Koto systems?
As the structure is fully protected and the material is not bio-degradable the life span is greater than conventional Construction.
In many locations “Conventional Construction” has a “Dead Load Weight” of 3,400 kg per m3 – what is Koto DLW?
Where low wind speed considered normal the Dead Load Weight would be 320 kg/m3, whereas in cyclonic high wind speeds it could reach 390 kg / m3 pending structural engineers shop drawings.

Either way the Koto system has huge benefits with its “Low” Dead Load Weight.

Do I need to erect full scaffolding like conventional flooring for the Koto Floor-Deck System?
No, the Koto Floor-Deck has reinforced ribs and once placed you can immediately walk on the form without props, however, we do have different types for different applications.
How many workers are required to install a Koto home as seen on youtube in 7 days to 14 days?
7 unskilled men installed the 3 bedroom x 2 bathroom 90 m2 home.
