A basement wall leak: The reason without making waterproof or waterproof basement did not do. There are tiny pores inside is not dense form seepage channel, groundwater under pressure into the channel, causing the wall leakage. Maintenance: The lower the water table, try to operate under anhydrous state, the first leak scrub clean the walls, remove the fill level, wall cutting hair with a waterproof material quickly stanch smear the walls, to be solidified after hollowing Department with a suitable waterproof paint or new waterproof materials and then brushing again. According wall leaks, using a variety of methods governing leakage, such as ferric chloride waterproof mortar surface treatment. M1500 spraying cement sealant. Cyanide coagulant treatment method. Second, damp walls: Reason: rigid waterproof layer Bohou uneven. TROWELING not dense or leak wipe, wipe rigid waterproof layer after curing is not sufficient, early mortar dehydration polyurethane waterproof coating, waterproof layers have tiny cracks. Maintenance: Synaptic epoxy powder processing method. With an equal amount of ethylene diamine and reaction in acetone, acetone imine polyurethane waterproof coating specification, adding a mixture of epoxy resin and dibutyl, epoxy resin content of 16%, and a certain amount of Synaptic powder polyurethane waterproof coating manufacturers in clean, dry treatment after brushing the wall evenly. Third, the embedded parts leaking parts: Reason: around embedded parts, especially the lower part of the more difficult, pouring concrete, vibration compaction easy. Embedded surface rust, hard tight bond with concrete. Maintenance: Use tools embedded parts surrounding annular groove carved to expose embedded parts, rust and clean place to place, with a waterproof sealant around stuffing, and then do the surface water. Polyurethane waterproof coating to use: · Mixing: first liquid material into the container, then slowly add the powder, and stir for 3-5 minutes until a homogeneous slurry and no raw dough particles can be used; ( best to use blender) · Brushing: Brushing with a brush or brush directly at the base surface, the intensity of the use of uniform, can not leak brush; normally takes brushing 2 times (according to the use requirements), each brushing The thickness of no more than 1mm; once again a little before and after brushing dry solids were then (just sticky, usually spaced 1-2 hours) polyurethane waterproof coating indicators, front and rear vertical cross brushing, brushing the total thickness is 1- 2mm; if the coating has been cured, the first wet with water when brushing another. · Conservation: 24 hours after construction proposal cover with a damp cloth or spray coating the coating watering conservation. ? Protection: Take ban stampede after construction, rain, exposure, acute injury protection before completely dry. ? Check (closed water test): toilet, sink and other parts in the waterproof layer to dry (at least 24 hours in summer, winter, at least 48 hours) reservoir full of water for 48 hours to check the waterproofing eligibility. Light wall water spray test to be done.
