GRIZZLY professional s.r.o. carries out the renovation of the walls of more than 200 buildings every year, including cultural monuments, sacral buildings, family houses, apartment buildings, administrative buildings, municipal offices, schools and the like. Our company develops and manufactures machines and insulation materials in the field of subsequent waterproofing. The many years of experience of our colleagues is a guarantee that we perform fast and precise work for our customers with reliable technology. We have ISO 9001, ISO 14001 and ISO 45001 quality certificates issued by the German accreditation company TÜV SÜD. We carry out remediation works qualitatively, precisely, according to approved technological procedures. Technological procedures Insulation technologies We use four methods to insulate walls: Chain saw wall cutting, Diamond wire wall cutting, Wall insulation with chrome-nickel steel sheets, Wall injection. We can cut through all types of materials: fired brick, adobe brick, stone masonry, cinder concrete, concrete, or reinforced concrete. Determining the insulation method A decisive factor is the determination of the material of the wall, the binding material and the checking of its quality (e.g. clay or mortar) We use four methods to insulate walls, we can cut through all types of materials: fired brick, adobe brick, stone masonry, cinder concrete, concrete, or reinforced concrete. Determining the cutting height Before starting work, we determine the cutting height, which can be at the height of the original waterproofing or according to the customer's needs - ideally, the cutting height should not exceed the planned walking height of the interior and, at the same time, should not be lower than the height of the screed concrete underneath. Wall cutting The procedure begins by determining the cutting height. This is followed by cutting through the entire width of the wall using a carbide-tungsten or diamond chain. After each cut section (1 meter or less), we place a 2mm thick polyethylene film in the groove. Insertion of stabilizing wedges We wedge the cut with polypropylene slats of various thicknesses, thus preventing the wall from sinking. The load-bearing capacity of the wedges is 500 kg/cm2, and each can hold several tons. These wedges remain in the cut. Filling the gaps between the wedges As a unique feature, we have a device that can introduce a dense, flexible, industrial-grade construction adhesive into the cut. A common mistake made by some companies is to fill the cut with ordinary PU foam or even watery cement, which can lose up to 40% of its volume after drying. In such cases, cracks often form, giving home to ant colonies nesting in the wall. 100 year guarantee The plastic insulation installed in this way prevents the absorption of water and radon. Their lifespan is the longest of all insulation materials, and they have excellent physical and chemical resistance. On-site survey Contact us by phone or e-mail to arrange an appointment to assess the condition of the building. Humidity measurement We use a special GANN B hygrometer to measure the moisture in the walls. This measuring instrument provides information about the moisture content of the masonry up to a depth of 4 cm. After that, probes must also be carried out to determine what type of material the individual partition walls are made of. The condition of the original insulation We assess the condition of the original insulation. During the survey, we determine whether subsequent waterproofing is necessary, or whether the problem can be remedied in another way. Survey After checking and laser measuring all the walls, we prepare a preliminary price calculation. Preparation of the price offer After the on-site survey, we prepare an exact price offer for the insulation of the walls. The date of execution We will agree the date of execution with you and arrive on the agreed date at the agreed time. We complete the insulation of a family house within 1-2 days. We carry out our work with responsibility. Keeping in mind the needs of our customers, we recommend the most effective solution to eliminate the dampness of the walls. We complete the insulation of an average family house in 1-2 days.
