    By including all these steps in the decontamination method, better results are achieved than with known decontamination methods.
    In a particular embodiment of the decontamination method, holes in the blind bottom are taken up after step 1 and before step 2. In another advantageous embodiment of the decontamination method, negative pressure is created with an extraction opening located near the bottom of the crawl space in step 5. These embodiments are particularly much more effective. decontamination.
    Brief description of the figures Fig. 1 shows in cross section a creeping ground prepared for decontamination Description of preferred embodiments Fig. 1 shows in cross section a creeping ground on a house prepared for decontamination. The floor on the ground floor consists of a chipboard and below this a blind bottom with insulation between them. Through the blind bottom, holes 3 have been taken up, as close to the edge beam as possible and in each floor compartment and also in the middle of the blind bottom in each floor compartment, for the ventilation process described below which forms part of the decontamination method. The housing bottom is supported by an edge beam 4 and on this lies an awl 5. The space between the edge beam and the blind bottom has been sealed with cellular plastic 6 and the joint between the cellular plastic seal and the edge beam and in the joint between the cellular plastic seal and the blind bottom joint joints 8 have been added for further sealing. Also in the joint between the edge beam and the landslide protection 8, a joint groove has been added for sealing. The ground surface in the crawl space is covered with a moisture barrier 9. The figure also illustrates the important drain valve 10 which is important for understanding the decontamination method, as well as part of a wall with mineral wool in the outer walls.
    An example of an approach to decontamination in the creeping ground according to the invention is described below, especially intended for moisture and light decontamination. An inspection hatch is arranged, for example, in a bedroom and preferably hidden as under a bed. To minimize damage to the property, the inspection hatch is placed between two floor beams. 2. A fi barrier is laid out on the ground with the seams ornlott about 20 cm. The moisture barrier ends approx. 5 cm from the inside of the edge beam and with a small elevation of approx. 5 cm, this is because if rain or melt water should run down into the crawl space, the water then flows under the plastic. 3. All air leakage from the outside that can enter the crawl space is sealed very carefully with cellular plastic 6 and sealant foam 8, as illustrated in fi g. l. The sealing is carried out between the race protection and the edge beam, between the sill and the edge beam, all joints in the concrete beams, towards the garage and all supply air valves, except when the duct assembly is mounted in a non-slip supply air valve. The slide guards, preferably made of sheet metal or reinforced plastic sheets, must be fitted correctly. 4. A duct fl genuine is arranged so that negative pressure can be achieved in the creep chamber when it is sealed. An aluminum fl ex hose is mounted on the duct inlet of the duct, typically with a diameter of 160 mm and a length of 2 m. The open end of the aluminum pipe is laid on the moisture barrier on the ground. Holes with a diameter of preferably 65 mm are drilled in the blind bottom between each floor beam compartment and as close to the edge beam as possible around the whole house and in addition in the floor space in each floor bell compartment. 6. The blind bottom of fi is reduced to about 10% moisture ratio with a dehumidifier. The drier the material, the better the odor removal. 7. In all rooms, a supply air valve, typically an 80 mm poppet valve, is mounted, and a further one above the front door. The supply air valve is mounted at the bottom with a hammer band. 8. The tightness of the crawl space is checked by setting the channel fl spike to the highest speed, which in the practical example is 850 m; air per hour. The inspection hole is sealed, then it is checked manually if all seals are satisfactory and otherwise the joint foam is supplemented 8. 9. The crawl space is heated up to approx. + 20 ° with, for example, a building eller fire or a passenger compartment heater before the upcoming ozone treatment. Odor molecules get better when the material and air are hot. 10. The inspection hatch is covered with a plywood board and sealed with silver tape. There is a hole in the plywood board, in the example with a diameter of 130 mm, where a plastic pipe that closes tightly around the hole is mounted. The plastic pipe is mounted in a fl marriage, in the example a so-called I-IP fl marriage with an air capacity of about 1500 m2 of air per hour and the marriage creates an overpressure in the crawl space. Two ozone units are placed next to the fl spout and the ozone is then pushed down into the crawl space and pushed into the drilled holes 3 in the blind bottom. The ozone is pushed into the entire floor construction and also into the outer wall insulation.
    The ozone removes the bad smell that has arisen as a result of moisture damage such as mold odor.
    The ozone treatment is carried out for about 3.5 days and the ozone units emit 12 grams ppm together during this time period. 12. The ozone treatment is carried out in the home for at least 2 days and up to 3.5 days, depending on how long it has smelled and how strong the smell. All clothes and the like are spread out or hung on a clothes rail so that the ozone enters the material. Two axial kt spikes are placed in suitable places in the home. All floor plinths are pushed out approx. 2 mm from the walls and all supply and exhaust air valves are closed. The temperature in the home is raised to about 24-25 ° C. When the ozone treatment is carried out, the power to the ozone units is cut off and the channel flap in the crawl space is started up at the highest speed.
    The ozone is then sucked down into the crawl space behind floor plinths, pipe penetrations etc. After about 5 hours, the ozone is vented by opening doors and windows. 12. Negative pressure measurement is performed in the crawl space.
    An important aspect of the decontamination method is that the ductwork achieves a negative pressure in the crawl space when it is sealed. Furthermore, the fact that the duct fan with its inlet pipe sucks out air from the bottom of the crawl space right next to the moisture barrier means that the method maintains the absence of mold odor or other disturbing odors that have arisen as a result of moisture damage. Through the placement of the hole 3, ozone is pumped into and air is drawn out of both the panty bottom and the walls.
    During the ozone treatment, the ozone is pushed into the crawl space with overpressure and the ozone then penetrates into the floor construction and into the outer wall insulation, so the cause of bad air is also affected there.
