Yong condensate scientific application of DPS in the basement, and garage
December 11 2019


Cretesealer DPS 【 basement, garage leaking much more special, generally between shear wall and beam, wall body strength is not enough, can not check hose to 】 

1. Basic level processing: before use, basement, garage at the grass-roots level surface must be completely clean and make sure the base of voids, pits and crack, degeneration be fixed. Base level water wet, but MingShui surface does not exist. 
 
2. Don't DPS will be diluted or mixed with other liquid. Spray directly with concentrate, shake well before use will solution (at least 1 minute), until foaming. Have frozen phenomenon, such as solution to melt completely before use, material performance is not affected. 
 
3. With the brush, roller brush, or large and medium-sized low-voltage sprayer is advisable. DPS should ensure evenly, so that surface saturated. For vertical walls, to upgrade daub DPS from heel of the wall, to ensure that smear evenly. Spray carefully to prevent omissions. 
 
4. Don't use DPS in aluminum, the surface of the glaze or glass, or corrosion will happen; One thousand casual contact, want to wash. 
 
5. The construction of the environment temperature is between 5 to 35 ℃. 
 
6. If there is any place such as the basement floor or wall pipe, to wear in the first concrete spraying again, cover with cement mortar spraying twice again. 
 
7. The new pouring concrete, when the structures have been confirmed within 24 hours or removal of the template (the person), first remove the grease of the template or mud. Immediately with the DPS surface processing, the surface state of saturated. Should pay attention to the tier 2 DPS on besmear again after 24 hours a day. 
 
8. The defect treatment: 
 
(1) in case of crack width is greater than 0.3 mm that must be handled as follows: the cracks open V groove, the depth should not be less than 30 mm, V groove is clean, rinse, after natural drying spray over the DPS, and blended with grout filling V groove, smoothing, spray twice the DPS. 
 
? For garage, basement has a surface crack of no less than 3 mm and water seepage, surface spraying DPS, completely with water mud filling cracks (with 1 part water and 1 copy of DPS with cement mixing, 3-4) to achieve the suitable concentration of slurry in 15 minutes. After the slurry filling cracks, knife surface leveling with a shovel, and then use a soft brush water wet surface. Spraying the DPS, again after 10 minutes, again to the slurry filling to the concrete crack; On the third layer of DPS. Twenty minutes later, the slurry filling to the cracks of concrete; On the fourth floor DPS. The fullest use of DPS in places have maintenance. Such as surface water flow at the rate of greater than 4 liters/hour, repeat the above steps. When necessary the epoxy resin into cracks or holes in it. 
 
? Should be decided according to the concrete base of the absorbing exert weight, under normal circumstances, the general concrete used only two layers of DPS. Generally applied weight should be 0.2 0.3 kg/square meters. According to site condition, in the partial penetration of concrete and the porosity of the big place to fully use the DPS. 
 
? Cretesealer DPS besmear to brush, infiltration time about 2 to 3 hours after 30 minutes after processing allows light touch. 3 hours, or on the surface of dry ground to walk. Can spray after 3 to 7 days, backfill or other component. 
 
? Detail structure processing: to sink in and out of the pipe mouth part, such as to use condensate DPS brush processing in advance, and then large area construction. That may destroy the waterproof seal integrity of some of the detail structure, such as through the pipes of the waterproof layer of post-cast strip, embedded parts, deep, construction joints, cracks, etc., are effective waterproof and strengthening measures must be taken to improve its rigor. Construction joint parts of the garage, basement exterior wall, Yin and Yang Angle should be handled as strengthening layer. Strengthen the treatment can be caused by.
