Treatment of percolation water common disease in newly built residential quarters (3)
3. Analysis and treatment plan for water seepage in the root of sunlight room
3.1 Accident characteristics
The root of the sun room is seeping through the water.
3.2 Cause analysis
(1) The detailed waterproof structure design of the sun room is unreasonable and the construction is not standardized.
(2) The concrete concrete flanging base is not cleaned, and the concrete pouring is not dense.
(3) The outer side of the cuffed root is not waterproofed and the outer side is higher than the inner side.
3.3 Processing method
(1) Remove all the polyurethane foaming agent under the sun room bottom frame, first use polymer latex to wash the aluminum alloy frame and the mortar surface together, and then solidify and then use the polymerized waterproof mortar to layer the embedded compact, and the frame and the wall are handed over. Sealed with weather resistant rubber.
(2) Cut off the brush layer on the outside of the flange, rinse it with pressure water, moisten it, apply the waterproof coating of Meihui waterproof coating, apply five layers of waterproof layer, and plaster with polymer waterproof mortar. The slope of flooding is ≥6%.
(3) The bottom of the sun room and the flange are sealed with silicone weatherproof glue.
3.4 preventive measures
(1) Flanging and structural panel concrete should be poured at one time.
(2) The strength grade of the flanged concrete should not be less than C2O, and the vibration of the plug-in vibrating rod should be used until the float emerges, especially the two ends of the flange and the wall must be vibrated and compacted.
(3) The concrete flanging root is brushed with Meihui JS one cloth and five coats, and the polymer waterproof mortar is used for plastering. The flooding degree is ≥6%, and the specific practices are detailed (Fig. 2).
(4) The sunlight room profile adopts glass curtain wall material, the wall thickness is ≥2.0mm, and the bottom frame is strictly prohibited to be spliced. Before the glass installation, the inner corner and the outer profile pipe joint must be sealed with silicone weatherproof glue.
3.5 quality control
The quality of the concrete pouring concrete and the bottom frame of the profile must be controlled.
Floor-to-door windows and doors that are connected to the outdoor terrace are also treated in the same way.
