Repair of joints of outer walls, restoration of gas and waterproofing of vertical surfaces
At compressor stations with gas compressor units in individual buildings for separations of premises of centrifugal blower and turbine engine there are dividing walls. These walls are panels from ceramsite concrete or gas silicate mounted on the metal structures of foundation beams and columns. Joints between panels are sealed with rubber porous gaskets and on both sides filled with cement grouping. Joint width is 50 mm.
During operation cement grouping of joint becomes cracked up to the spalling. In addition, the panels can become cracked or partially destructed. It leads to loss of tightness and consequently need for frequent repairs.
For finishing and restoration of dividing walls, to restore gas-tightness materials of domestic and foreign manufacturers are used:
- Polyurethane foam;
- Polyurethane sealant;
- Waterproofing coating;
- Non-shrink repair mortars;
- Special cements with polymer additives;
- Polyurethane coating;
- Polypropylene fibers;
- Fire-resistant organosilicate paint.
Materials are certified with hygienic and fire certificates, do not support combustion and have a wide operating temperature range (-60 ° C to +80 ° C; for fire-resistant organosilicate paint – from BO ° C to +600 ° C]. Used materials have a high mutual adhesion to each other and to the concrete, as well as high strength and elasticity.
