Construction method of roof waterproofing

Abstract

The invention discloses a roof waterproofing construction method, which includes the following construction steps: step 1: the top of a roof is cast by adopting micro-expansion concrete, the micro-expansion concrete is first vibrated in the process of casting, the top surface is leveled, and after leveling, plastering and trowelling are then carried out; step 2: after micro-expansion concrete casting is finished, the roof is covered by a layer of curing membrane, wherein a concrete sloping layer is arranged on the top surface of the curing membrane, and an insulation board is arranged on the concrete sloping layer; step 3: a mortar isolation layer is arranged on the top surface of the insulation board, and a fine aggregate concrete protection layer is arranged upon the mortar isolation layer. The roof waterproofing construction method has the following advantages: the anti-cracking and seepage-proof self-waterproofing effect of the roof is ensured effectively, the construction level is increased, construction quality is guaranteed, the construction method is simplified, man-hours are shortened, construction cost is reduced, and the expected service life of roof waterproofing is guaranteed.

Description

technical field [0001] The invention relates to a building construction method, more specifically, to a construction method for roof waterproofing. Background technique [0002] In the construction process of roof waterproofing, the existing technology usually adopts a flexible waterproof technical solution, and the waterproof effect cannot reach the expected effect of the design. In the flexible waterproof technical scheme, "SBS" high polymer modified asphalt waterproof membrane is usually used. The method is: use light aggregate concrete to find slopes on the roof structure layer, lay foamed concrete slabs, and spread a One or two layers of "SBS" high-polymer modified bitumen waterproofing membrane, low-strength grade mortar isolation layer, C20 fine stone concrete reinforcement protection layer, and non-slip floor tiles should be laid on the roof. [0003] In flexible waterproof technology, whether it is a leveling layer or an insulation layer, the material itself is lig...

Problems solved by technology

Once there is a crack, the sealing body will be destroyed immediately. When it rains, the roof will be in a humid environment for a long time. The reason for the pores is that the amount of water after water absorption is quite large, which can reach 60-70% of the material weight of the insulation layer and slope-finding layer. As long as the roof structure layer is not dense, it will naturally become a leak point, and the leak point is extremely difficult to find , cannot be dealt with in time; in addition, the leakage point not only leaks in rainy days, but also leaks in sunny days, which brings great difficulty to roof maintenance and shortens the service life of roof waterproofing membranes
