Shandong waterproof board manufacturers introduce basement waterproofing basement steps, generally placed our debris. If the basement seepage, then it may not be great. Unventilated basement, flooded not easily evaporate. Moldy phenomenon will likely occur this way. To prevent this phenomenon, we introduce the detailed steps basement waterproofing. First, the process substrate 1, to remove the exposed brick interior and exterior cement mortar. 2, the interior walls from the ground back to 1m, to remove the cement mortar exposed brick. 3, removal of ground cement mortar. Second, after blocking the leakage of primary treatment, to identify leakage site. 1, point ① sealing properly identify the leaking leak site to leakage points as the center, hewn diameter 30 ~ 50mm, 30 ~ 60mm depth of the hole, Then the debris cleared away, and washed with water. ② use TS96 permeable closed and 425 # ordinary portland cement mix, with the ratio of closed plastic: cement = 1: 1.5 (weight ratio). Mix to be hardened solidified in 40 seconds to 2 minutes. ③ the mix to knead and close the hole diameter or cone bolt body, quickly forced to plug in the hole, and to squeeze tight around. Then pressed his hand tightly, it closely integrated with the hole wall, (2 minutes) to be cured before they sell. 2, sew the seam sealing leakage roulette hewn V-type or U-shaped groove, width 20 ~ 40mm, depth 30 ~ 150mm (the greater the pressure to be deeper), the construction should segment plugging, plugging method as above . 3, a large area of ??slow seepage treatment ① the seepage face clean, wipe dry floating. ② brushing a closed plastic infiltration, immediately wipe a rub for cement powder. ③ excess cement powder scraped, then repeat the last operation, repeated construction 2 to 4 times until the water is blocked up. ④ then according to the aforementioned "basement waterproofing" in waterproof mortar waterproof construction, completely solve the leakage problem. Construction of a waterproof mortar, waterproof mortar ratio: waterproof mortar, cement: sand = 1: 2.5 to 2.8 10% siliceous cement waterproofing agent, use Portland cement or cement ordinary portland cement; strength grade not lower to 325 #. Basement water level should be reduced to the work surface 500mm or less, and maintain until completion. 2, thick outer wall waterproofing mortar 20mm, using wiping pressure two times two times, once viable practice, each compacted once again wipes close the water. 3, the interior vertical wall waterproofing mortar thickness of 30mm, using wiping three times, press three times, once viable practice, when the collection of water per wipes once again secondary compaction. 4, ground waterproof mortar 30mm, using wiping two times, press two times a viable practice, when income per wipes water, the secondary pressure once again. Kok Yin and Yang should be 50 ~ 60mm fillet. As pasting tiles, waterproof layer after the second calender twist pockmarked face.
