Waterproofing of the basement with liquid glass

One of inexpensive and simple way to protect the foundation from getting wet - waterproofing with liquid glass.Liquid glass is prepared as follows: the aqueous salt solution is mixed with quartz sand and soda, and calcined crystals obtained water-soluble calcium or sodium silicate, which is dissolved in water to the desired thickness.

property of sodium silicate adhesive behavior and improve the concrete to fill the pores of insoluble crystals forms the basis of modern mixes for penetrating waterproofing.It is also possible to use for this purpose a conventional liquid glass.

Types waterproofing liquid glass

There are several ways to perform the waterproofing with liquid glass, and each uses a different technology.

• surface waterproofing under the roller and Wood banding waterproofing materials;
• penetrating waterproofing, cement-based;
• Monolithic concrete base with the addition of water glass.

When using water glass as a waterproofing material should be aware of the peculiarities of sodium silicate:

• Liquid glass dissolves in water, so Obmazochnaya basement waterproofing and pressure hydrostatic load is not reliable, and treated with liquid glass Concrete must also protect the roll materials;
• When adding sodium silicate cement mortars and concretes of decreasing strength, so the amount of sodium silicate in the solution to be not more than 3%;
• setting time mortar or concrete with liquid glass is very small, and mixing the solution with starting the process of setting is prohibited because the process is terminated at the same time.Therefore, the amount necessary to prepare a solution which can be used quickly.

technology surface waterproofing with liquid glass

surface waterproofing foundation liquid glass is applied when the use of solutions based on bitumen is undesirable, for example, when using polymeric roll material, which contact with oil or solvents is prohibited.By itself, the applied layer of sodium silicate is not protective, but in the process of interaction with the concrete waterglass its pores are filled with water-insoluble crystalline compounds.The thickness of the protective layer is not more than a few millimeters.If this is enough for a good seal section, the method of surface waterproofing with liquid glass is very convenient and cheap.

1. Prepare the surface for waterproofing: cleaned of dirt, dust, grease.Smooth concrete brush lightly sanded to open the pores and increase the depth of penetration of liquid glass.
2. Apply liquid glass with a broad brush, as the drying of the first layer can be applied to the second.
3. Dry the surface, and then proceed to roll back-lining or waterproofing.

technology of cement-silicate insulation penetrating

is used for rapid sealing leaks, joints and seams block foundation.The solution was prepared based on cement, spreading it with water added to it with liquid glass, the percentage of sodium silicate - up to 5% of the total.The solution hardens quickly, so prepare it in small portions.

1. seams, joints, foundation cracks or other damage should be prepared to spray a waterproofing solution.To do this, they embroider to solid concrete, remove them from the mud.For convenience, you can crack proshtrobit so that they acquired the U-shape.
2. solution for insulation penetrating prepared as follows: sodium silicate is mixed with water in a ratio of about 1:10 - 1:15, and the resulting solution was poured gradually into the mixture of dry cement or cement-based mono- and stirred.The solution should be thick and malleable.Stir the mixture several times is impossible, as this breaks the connection crystal formation started and the solution loses its properties.
   

   Preparation solution

Apply the solution in the seams or cracks with a spatula.For better adhesion surface may be slightly wet.Leveling compound on the surface and are completely dry.

Using water glass when pouring monolithic foundation

addition of sodium silicate or calcium silicate in the concrete mixture used to fill solid foundation, improve its waterproofing properties, and water-resistant natureconcrete covers the entire thickness of the foundation.In this somewhat increases its fragility and the tensile strength decreases, so when using the concrete with waterglass must amplify valve and increase the thickness of the sand bedding, especially for heaving soils.

1. Due to the fast setting modified concrete is necessary to prepare in advance all the necessary: ​​perform markup, preparing shuttering, reinforcement.To prepare
2. use water with dissolved water glass.To strike a balance between strength and gidroupornostyu, you must calculate the amount of sodium silicate so that its share in the total amount does not exceed 5%.
3. Mix the cement and sand, gradually pour in a solution of sodium silicate, stirred rapidly and add filler - expanded clay, gravel.You can also add fibrovolokno.

4. concrete solution is quickly poured into the mold, aligned horizontally and wait for it dry.Unlike conventional concrete mix the solution using a vibrator is not recommended, as this process is disrupted crystal formation and concrete setting.

5. After full maturity of his insulated concrete slabs of polystyrene.insulation function for such a foundation is not limited to thermal insulation - insulation also distributes the load evenly over the soil surface of the basement walls and protects it from damage and cracking.

basement waterproofing with liquid glass - a relatively cheap way of having side defects.If the terms of use of the building is not allowed deterioration of the strength of concrete, instead of liquid glass can be used modern solutions for penetrating waterproofing of the foundation.
