The main defects of stairs: longitudinal and transverse cracks stages, chipping and potholes on the rollers steps, erasing treads, sliding steps from their seats, loose railings, the destruction of the finishing layer and ceramic tiles on the walls of the brick stairs.
Longitudinal and transverse cracks in concrete and brick steps expand a little and sealed with cement mortar. Rollers chipped concrete steps can be strengthened with metal corners, embedded in the brickwork. Crawl space with concrete steps to strengthen the lower part of steel angle or brand.
With strong abrasion tread made of reinforced concrete or brick, top notch stage and wear mortar on a steel grid. Cranky rack railing embedded in advanced stages of the nest of concrete, steel scraps wedges and pour tse-element solution of molten sulfur or lead. Battered wooden stairs step removed from the nest, clearing the nest and fed new elements. On the stage was packed metal strips or corners. Surface worn wooden steps screed epoxy with sawdust. Stairs, across the cracked, replace the new one.
If in some places along the entire length of the march broken string, then install an additional side and secure it with bolts to the core. For more the string cut into a ploshchadochnyj beam.
If the beam is broken ploshchadochnyj at considerable length, the inside of the set and an additional beam is fixed to the walls and shattered. Damaged rollers repaired by gluing and screwing them to the new standards of solid wood. Longitudinal cracks tightening the band steel or wooden plate.
Creaking stairs eliminate several ways. When accessing the bottom of the stairs in the seam between the tread and the riser inserted a thin film, smeared with glue. If a step in favor of the riser, then move close to the last board to slightly raise the treads or screwed to the riser rail.
