Frequently Asked Questions

  • The habitats of TECdream are innovative and modern, given that they explore a constructive technology that is fast, accurate, and ecologically sustainable. Our habitats have excellent thermal and acoustic insulation, are extremely safe against fires, and ensures a superior air quality
    inside each home. Given this great thermal insulation, the ICF construction system allows savings with air conditioning in the order of 50%. In addition to this, a normal size construction takes on average 10 to 12 months to be ready to inhabit.
    TECdream’s habitats require an extremely reduced maintenance, because it involves materials with high durability and mechanical resistance, of which stands out the concrete-reinforced and fibro-reinforced mortars.
    A TECdream’s building is not subject to problems associated with contractions and dilations of unusual materials like in wooden constructions, nor to the usual corrosion problems in metalware.
    TECdream blocks are prepared to receive directly all types of finishing materials, without having to add any kind of thermal insulation. The exterior walls are finished with fibro-reinforced mortars in the desired color (ETICS System).
    However, you may apply another type of flooring such as ceramic, phenolic or stone. The interior walls also offer a varied range of finishing materials, such as plaster, stucco, stroked ceramic, stone or wood.
    Yes. The mentioned pathology results usually the presence of moisture in the walls climb which leads to a physical and aesthetic degradation of the accelerated cement plaster and masonry, being characterized by a moisture stain usually at the base of the walls and by the appearance of whitish.
    When recurring to TECdream’s constructive system, this type of pathology is virtually eliminated, because the EPS water absorption capacity is insignificant (aprox. 2%) when compared with the level of absorption of mortar and masonry. Anyway, all underground walls should be sealed properly.
    In which concerns the fixing of lightweight materials (e.g. pictures), it is important to note that it is not the brick that supports these elements in traditional construction. What offers resistance are the finishing materials (stucco or plaster). Once the finishing materials applied on EPS will be identical, these mortars can easily withstand relatively light elements.
    However, when you want to apply the walls heavy elements (e.g. cupboards, flat), you just have to be careful using concrete screws with sufficient length to achieve the concrete (usually: 12cm). There is no need to recurre to chemical dowels as in brick walls.

  • The installation of hydraulic and electrical infrastructure has never been so simple, since the same will be soaked in EPS interior Panel with 65 mm thick, which is easy and fast to cut.
    With the ICF system cease to exist ditches in reinforced concrete and masonry, which damage the structure, are time consuming and create waste.
    Correct. You only need to apply the brace on one side, because the panels are linked by connectors of HDPE (High Density Polypropylene). Therefore, ensuring the adequate shoring and plumbing of the interior side of the wall,
    the outer wall also will present the same features, without having to perform additional operations. We emphasize, however, that the spacing between anchors must not be more than 1,20 meters.
    Yes. It is possible to make a casting of a wall with 3 metres of height in a single operation. The same is done in layers with a maximum of 0.75 meters high. Usually the beginning of the casting of each layer is lagged by 1 hour. We stresse that, in order to avoid the possibility of the phenomenon of disaggregation of concrete elements, due to the height of the casting, one must recurre to a countercurve (see photograph below) that is installed on the edge of the concrete pump, thus reducing the output speed of the concrete.
    It should be also noted that the household size of the concrete must be less than 16 mm, in order to ensure adequate vibration of concrete. The vibration of the same shall be made with a vibrator with a diameter of roughly 25-38 mm.
    Usually, traditional construction irrigates the concrete due to the fact that the mixing water evaporates very quickly, which is fundamental for the proper hydrationof the concrete. With TECdream’s constructive system, the water evaporation does not occur, because the walls’ surfaces are not directly exposed to the wind and the Sun
    once they are insulated by EPS. As such, TECdream’s constructive system provides a proper cure to concrete, without having to perform additional operations after casting, thereby minimizing human error and improving the characteristics of concrete resistance.
    Firstly, the waste resulting from TECdream’s constructive system is residual (3%) when compared to traditional construction waste (15% to 20&). Anyway, the TECdream products are composed of EPS (Expanded Polystyrene) and HDPE (High Density
    Polypropylene), that can be recycled or easily incorporated in the construction of buildings. It is usual to crunch the EPS that later will be part of the composition of light fillers used in different parts of the buildings.

    Wonderful post but I was wanting to know if you could write a litte more on this topic? I’d be very thankful if you could elaborate a little bit more. Cheers!

  2. Does your site have a contact page? I’m having problems locating it but, I’d like to shoot you an e-mail. I’ve got some creative ideas for your blog you might be interested in hearing. Either way, great website and I look forward to seeing it grow over time.

  3. I just added this site to my feed reader, great stuff. Cannot get enough!
