Construction companies
Oulu Kosteustutkimus is a trusted accomplice of production groups with long and versatile revel in tough initiatives. We can offer all services related to new construction: humidity measurements, humidity manipulation, drying and heating, tightness measurements, dust control, and thermal camera imaging. We usually use modern information, knowledge, and equipment inside the field. Call Pirauta on 010 219 5000 or email okt@oulunkosteustutkimus.Fi and we will communicate more!
Moisture control
Our moisture control offerings encompass drying, tracking systems, moisture measurements, and dimension plans. The carrier package is tailored to every website. We use numerous distinct structures for moisture management, and we will reveal the situations and the drying of the systems remotely on behalf of the development website. Our workforce acts because of the right hand of the website's moisture coordinator.
We find out the moisture content of the structure as relative humidity (RH%) according to the instructions of the rt card (RT-14-10984). Rakennusliike Oulu During the construction paintings, it must be ensured before coating that the systems have dried sufficiently before beginning the coating work.
Concrete ground moisture dimension is done either by means of borehole size or by means of the sample piece technique. In borehole size, a enough variety of holes are drilled into the shape to a certain intensity, which might be cautiously wiped clean, piped and plugged. The holes are allowed to accept approximately three days, after which the moisture percent and temperature of the shape are measured. In the sample approach, pattern portions are taken from the concrete slab right into a check tube, that are measured after the settling time. The humidity of the shape can be observed out quick, and the situations of the dimension region do now not have an effect on the measurement outcomes.
Our measuring equipment is the modern day measuring equipment in the industry. We perform the calibration of the measuring heads about each 3 months and a check with each measurement.
Building tightness dimension
By measuring the tightness of buildings, the thermal and moisture-technical characteristic of the structures is ensured, in addition to the building's energy performance and living comfort.
Moisture contained in warm indoor air can condense on bloodless structures at air leakage points. This consequences in the hazard of moisture and microbial damage. When the constructing's airtightness is good, the moisture inner can not get into the systems. An hermetic constructing does not sense drafty and its indoor air is wholesome and smooth. An hermetic constructing additionally consumes less power.
Airtightness size means figuring out the air leakage range of the building's outer envelope at a pressure difference of fifty pa. The stress distinction is carried out with a stress take a look at, during which the building is beneath- or over-pressurized to test the air tightness.
We use Retrotec's tightness dimension equipment. The usage variety of our gadget is 6 – 24,636 m 2 /h. This enables tightness dimension from small condominiums to entire condominium homes. Our personnel has the personal certificate of a constructing tightness tester.
Thermal imaging
Thermal imaging is a short manner to show thermal problems in the building's structures with out breaking the structures. It provides dependable facts approximately the heat and air leaks affecting the belongings's strength consumption, which boom strength consumption and reduce the comfort of dwelling.
Thermal imaging also can be used as a part of the great manage of a brand new property, which ensures the excessive first-rate of housing manufacturing.
Oulu Moisture Research is a pioneer in Northern Finland in thermal imaging. We started out thermal imaging in 1998 with the so-referred to as with a nitrogen digicam, and in 2000 we have been the primary in Oulu to exchange to a matrix digital camera. We replace our equipment regularly. With our present day digicam, thermal imaging can be executed in temperature differences of up to ten–15 tiers. The decision is much less than zero.03 celsius. We use IT-primarily based thermal picture analysis and reporting.
Water damage in the course of construction
If water damage takes place on the construction web page, we can help - from set off first useful resource to drying and damage and moisture mapping. For acute conditions, we use the Hälykarry, which lets in us to map the damage and limit its expansion quickly. Read extra approximately our versatile offerings related to water damage.
