Q&A for Architects
Is there design software available?
Polycare makes use of our specialised design software, the Polybuilder, which calculates the optimal and most efficient use of the elements based on the available planning documents. Existing plan layouts can be converted to the Polycare system.
What roofing options are available?
Essentially all roofing systems can be used.
What are the design limitations?
Within reason, building with Polyblocks is virtually unlimited. Most straight wall configurations can be realised.
Can I build more than one story with Polyblocks?
In the near future it will possible.
Is it possible to use Polyblocks for both structural and non-structural wall elements?
Yes, Polyblocks can be used for both structural and non-structural walling elements.
What is depth/width of a Polyblock?
20 centimeter
How flexible can I be with the height?
The blocks have a height of 30cm, so height can be increased in increments of 30cm at a time.
Benefits for Architects
Help from a technical partner
Design workshops are provided
Easy to transport due to lightweight
Various expansion possibilities
Access to Polybuilder for design process
Very short construction time
Possibility to plaster and paint
Quality control of the brick usage
Q&A for Developers
Is Polycare’s system certified and accepted in Namibia?
Yes. Polycare’s system is assessed and certified by Agrément South Africa as required for building with alternative methods in South Africa and also Namibia. Agrément is an independent organisation that evaluates the fitness for purpose of non-standardised building and construction products and systems by applying performance-based criteria in its assessment procedure. Polycare technology system has also been tested extensively in Germany and complies with German standards. Furthermore, Polycare’s system is accepted by the City of Windhoek as a permanent structure and is financed by local banks.
How does Polycare save costs?
Our system saves costs by having shorter onsite requirement and risk periods for developers, saving on professional fees, as well as reduced transport costs on material delivery and waste cleanup.
Is there a building permit?
Basically not. The procedure is the same as for a conventionally built house.
How is plumbing and electrical installation accommodated?
Polyblocks allow for plumbing and electrical installation where conduits and pipes are inserted inside the blocks as the walls are constructed. Conventional piping, conduits, fittings and wiring is used.
Which specialists are needed for this?
No skilled personnel are required to set up and dismantle Polyblocks. The use is limited to planning and construction supervision.
Benefits for Developers
No mortar and glue is needed
Can be build by unskilled workers
Easy to transport due to lightweight
Various expansion possibilities
General Q&A
How much does it cost to build with Polyblocks?
The material cost depends on the layout & size of the project you have in mind, if you’d like to get a rough idea of a quotation, take a look at our project catalogue.
Can I build the house myself?
Yes, the system is very well suited to build your house by yourself. This would require basic training and Polycare will be obligated to certify compliance to the correct use of the system.
Can I use regular plastering and paint on the walls?
We use a textured plaster paint for plastering inside our buildings.
Will moisture seep in if I do not plaster the blocks?
A sealant (plaster or textured plaster paint) is applied and prevents any possibility of moisture damage. Polyblocks have a great longevity and are even more weather resistant than conventional building blocks.
Are there health concerns when building with polymer concrete?
No, there are no concerns or risks when building with Polyblocks. Our system is environmentally friendly and can even be used in drinking water protection areas. This has been determined and certified by independent institutions.
How is the interior construction of the house done?
Polyblocks are used for planning and building in a 10 cm grid. The interior can be finished with texture plaster paint, plasterboard or other materials. In principle, there are no restrictions here.
How does the technology work?
The Polyblocks have a relatively thin outer layer and the inside of the elements contain insulation cores. There are six basic elements and some special blocks, such as the sanitary block that makes provision for the fitment of sanitary ware such as basins. The blocks are dry-stacked and anchored between the floor and ring beams with steel rods.
What does the value chain look like?
The value creation takes place on site. By using local fillers and local labour, the major part of the added value remains in the respective application area.
Is the system expandable?
One of the advantages of building with Polyblocks is that extending your construction project is made much more efficient and easier. This system is ideal for building in phases.
How soundproof are the walls?
Polyblocks are made up of 80% insulation meaning that not only do they keep the internal temperature consistent, but that they have the same soundproofing abilities as conventional building blocks.
Are the blocks fireproof? Will they melt in the event of a fire?
Polymer concrete consists of part resin, but the material cannot be liquified again. Polycare walls have a fire resistance class of 30 minutes, and with added fire protection plaster from Polycare, a higher fire resistance class can be achieved.
Do I need a foundation or a floor slab to be able to build with Polyblocks?
No, to build a house you don’t need a foundation or floor slab, the use of our beams makes it obsolete. However, Namibian municipal regulations do require a concrete foundation and floor slab.
Can I make holes in Polyblocks to hang pictures etc inside my house?
Yes. The method changes to the conventional system, by drilling a pilot hole in the Polyblocks a screw can be installed for hanging picture etc.
General Benefits
60% less carbon emissions
Zero water used in manufacturing of Polyblocks
Polyblocks can be dismantled and reused
Minimal waste produced on site
