Flat roof repair and maintenance of the waterproof layer


Protection layer, remove the crack of floating dust, brush oil on the cold foundation, cracks win ointment or clay, should be above the waterproof layer 8 [nrll about 250mm wide and then spread the oil in the above article felt (or glass fiber cloth), oil blankets the middle section slightly convex curved shape, with hot asphalt oil felt at both ends of discrimination Results paste prison, and finally make a 380mm wide felt a protective layer of oil sands green beans. No rule of cracks, each crack in a crack in the build-up or health protective layer of sand around the elimination of green beans and cleaned surface dust. Foundation brush of cold oil, spread a blanket or a Second City Second oil gel. - Received I999 ~ 03-29 @ 3 Wuwan Jun: flat roof repair and maintenance of the waterproof layer insulation layer 87 pairs, some of the damaged insulating layer to re-handle according to the construction specifications, coil aging, in part to re-fracture for materials, which re-engage in a blanket or two blankets two oil three oil; membrane hollowing, wing edges and seal torn off to reveal it with a bonding material posted flat, asphalt flowed at mung bean can add a little sand to stop it. On the rigid roof leak problems for many years to be completely resolved. To use more fat pitch over the past Marti, hemp and other filling them with sub-grid reinforced seam, in the face of oil plus one or two felt felt two three oils, but its effect did not meet expectations. In recent years, we used tung oil bitumen ointment, patch the roof sub-frame joints, the effect is good, so far found no leakage. The specific practice of caulking is the first cracks in the drilling irregular, wide 20InIn, depth 25mm, and then sew the debris cleaned with a brush to make the ointment with the underlying bond closely on the larger than 30tnrll sew, use 1:3 cement mortar joints wiping wide 20InIn. Depth 25mm, and then fill out caulking ointment. This will not affect the construction quality. Would not raise the cost. Construction requirements of the roof dry, not wet, rain and snow Wulu weather, not construction. Special circumstances can be torch to dry wet slab construction. Cream filling cracks, should be painted cold-base oil again, until dry and then crack with a smooth paste the embed child within a fracture, filled to close Xi, so that it closely with the primary cement. Feast of the fracture pressure cream should be slightly higher than the slab in order to avoid accumulation of water. Ointment must be greater than the width of hem 200tntn, then paste in the cracks on the surface, including the No. 2 uniform coating layer, coating the surface of the flat glass fiber cloth Stones (cloth take the head about 100mil1). Brush the surface of the cloth over the oil-ling foundation for smooth ointment, and finally repeated evenly paint brush on a layer 2, the coating on the mica surface even withdraw. It should also be noted that crack cream is finished, plus not use solvents and other filler to prevent changes in the performance of ointment. Construction in the winter, cracks slightly hard paste a little, the construction of suitable ointment can be heated, but non-direct heat with the fire, so as not to compromise quality. Waterproof layer of concrete surface weathering of the treatment, mainly covering method,[link widoczny dla zalogowanych], that is to be weathering the plate surface, covered with a protective layer. Commonly used 20mm thick protective layer of cement mortar and painted a variety of waterproof coating material that formed the wax protective layer on the pan of water at the aging failure ointment caulking, or caulking is not strong, and ointment or brick wall concrete torn off, resulting in leakage gap situation, should have been aging and off excavation ointment, ointment caulking the construction requirements by re-caulking. Solve the problem of leaking flat roof, is a long and complex issue, not once and for all, must be multifaceted efforts to improve comprehensive management. Emphasis on new construction to improve the water quality of the project; of completed houses to inspect, cleanse, strengthen management and protection, and timely maintenance. Also be appropriate to increase the project cost and maintenance cost, maximize the use of new waterproof technology, in order to better improve the roof leaking phenomenon, extended roof effective use of time, to ensure peace of the residents living ship.
