Lift pit is deep items on the ground should always suffer the pressure of groundwater; by the waterproof floor, basement wall joints and the solution that most investors and contractors should be selected.

1. Cleaning the surface to be waterproof

+ Clean the surface construction

+ Clean Cut out old mortar and the adhesive surface contaminants into the wall and bottom of the shaft.

+ Use of clean dirt.

+ All of the positions of countries have a water seepage or leakage through the use of chemicals quickly frozen immediately blocked again. In the case of leachate flowing water must be used TiO gradually shut off then each one location.

+ When no longer needed a water leak through the use of chemical resistant roller or scan the entire surface to be treatment resistant. Chemical rolling until no more moisture that phenomenon is stopped. At least two to three layers.

+ After rolling is complete using chemical additives, waterproofing against mixing efficiency mixed with cement and sand plastered over the entire surface layer of waterproof construction, the thickness of the plaster is 1-2cm ..

2. Handling the waterproofing

Step 1: Scan permeable surface layer Beton.

- Mixed Mixed Lemax Seal + 10 liters of water + 3 kg cement, stir to scan the surface permeability of concrete (note scan it all and avoid omitted).

Step 2: Conduct proof seal leaking seams

- Lemax Seal phase mixture of cement + 4 + 5 Kg liter of water, then use the solution just enough Lemax 201 rate at the levels available on the packaging for this mixture (to mix pieces) until I Profile sensation and then plug right into the security leak.

- For large bruises, pressure water leaks should be sealed up in part by attaching a soft plastic tube into the heart stain repellent and stain repellent Sealing around this. When it reached the intensity stain repellent hard plastic tube that allows the virus and carry bruises covering the center back.

- Use the mortar bowl 100 bowl flat surface marking walls or floors. Note maintenance of water carefully, avoiding cracks in the surface mortar.

Step 3: Conduct treatment resistant surface layers.

- Grade 1: Phase mixture Lemax Seal liters + 4 + 5 Kg cement, stir and then scan the surface.

- Grade 2: After the first layer is completely dry, then proceed 2 scans perpendicular to the first layer (phase ratio as above).

- Grade 3: Phase mixture Lemax 201 liters + 4 + 5 Kg cement, stir and then scan the surface. (Scan this class really are not missing and just scanning the dried layer of 2)

NOTE: - If the surface waterproofing spray drying must be maintained. - If you need whitewashing or painting shall be conducted only when the waterproofing layer is completely dry.

ADVANTAGE - Improved waterproofing and adhesion of the mortar

- Increased resistance to alkali and acid

- Protection class front and moisture resistant when wet or phenomenon of osmosis water from other locations.

+ 1-2 cm thick plaster covering the entire bottom of the hole and into the elevator.

+ The drill location is to use glue to swell and fill the new pump construction chemicals.

+ Construction waste cleanup is complete and return the ground.

NOTE: The above is the common case in the works. In fact requires a survey to determine the true cause of permeability. The construction must have the experience and creativity in every situation the status of specific projects.
