Penetrating waterproofing the basement

Penetrating waterproofing the basement - a modern and reliable method of protection, based on the ability of specific products to fill the pores of the concrete is not soluble in water crystals, thereby gidrobarer while maintaining the water vapor permeability of the material.

The principle of penetrating waterproofing

Concrete - porous material, it is due to its property to absorb water.Tiny channels called capillaries pass water molecules to a considerable depth.Filled micro-cracks moisture during freezing water expands and increases capillary permeability of concrete.Concrete ages, collapses, begins to flow.In the presence of water and air within the structural reinforcement rust and corrosion products contribute to further destruction of the material.

The most severe conditions are objects that are in direct contact with the ground, for example, the foundation of the building: addition to water, it affects slightly alkaline or acidic soil components.Proven and popular basement waterproofing techniques such as Okleechnaya or surface waterproofing, protecting only the surface of the foundation, and at the slightest damage to begin to pass water.That is why in addition to equip a waterproofing drainage for removing moisture from the basement walls.

penetrating waterproofing has a completely different principle.Components waterproofing solutions and mixtures react with aluminum and calcium ions contained in the concrete to form a complex crystalline hydrates.The pores and capillaries in concrete gradually overgrown needle-type crystals, leaving small gaps through which water molecules can penetrate into the vapor form.In this case the capillary suction of water becomes impossible due to the surface tension of water droplets.

Filling the pores and capillaries of the concrete takes place with direct participation of water, so penetrating waterproofing can be carried out in wet basements.waterproofing layer is not limited to the concrete surface: crystal growth continues at a sufficient moisture can penetrate the concrete to a depth of 0.6 meters.Because of this property can be carried out waterproofing of the foundation both outside and inside the building, which is particularly useful in the repair of foundations of old buildings.

Types penetrating waterproofing

for various waterproofing use different types of penetrating waterproofing:

• aqueous solution for the treatment of intact concrete with a brush or by spraying.It is used mainly on new construction;
• mixture for application spatula.It creates a layer up to 2 mm is recommended for the restoration and waterproofing of old concrete structures;
• Waterproofing seams.Pretty thick mixture for repair and seal section seams.Used in conjunction with a liquid solution;
• compositions for repairing leaks and eliminate strong.Apply with the need to eliminate damage to the concrete.

foundation treatment technology

slurry is applied in the processing of new concrete block or monolithic foundations, both outside and inside the building.After treatment lasting waterproofing layer formed, in operation on contact with water renewed crystallization.

1. surface is cleaned of dust, dirt, stains, grease and bitumen.For better penetration of the solution into the pores of smooth concrete can be subjected to his sandblasting or wire brush to clean.Speakers of the valve cleaned of rust.The surface is washed with water under pressure to complete wetting of the concrete.
2. Ingredients mixed according to the instructions on the package, pouring water into the dry mixture and mixed thoroughly.It should get a mixture with the consistency of liquid sour cream.The composition is applied
3. wide brush in two coats, the holding time of the first layer is from 2 to 6 hours.When applying the second layer later than 6 hours after the first layer is necessary to clean the brush.Application of the composition is possible both from the street and inside the basement.For waterproofing of the foundation structures destroyed solution is diluted to a thick paste-like consistency and is applied with a spatula, about 2 mm thick.
4. decorative coatings is possible not earlier than 21 days after penetrating waterproofing of the foundation.

technology penetrating waterproofing of joints and seams

is used for the seams, joints and cracks in conjunction with the liquid penetrating waterproofing.It can also be used to repair damaged concrete surfaces.

1. concrete surface is cleaned of dust and dirt, wash with water.Cracks embroider, removing the remains of cement mortar in the joints perform Stroebe size 2,5h2,5 see using grinders or punch.
2. liberally moistened with cracks and Stroebe water with a brush or a sprayer.Treated cracks penetrating waterproofing grout and held from 2 to 6 hours.
3. Mix the required amount of dry mix with water to the consistency of modeling clay.Mortgage mixture into cracks and joints, hands or a spatula.If necessary, seal the cracks large in the solution you need to add gravel.When waterproofing of concrete structures with traces of the destruction layer of the mixture is applied with a spatula to 13 mm, in multiple layers.

hour after setting waterproofing solution to be processed seams liquid waterproofing solution.

repair technology foundation with penetrating waterproofing

This technology is used to eliminate leaks with strong hydrostatic pressure, it is based on the properties of the mixture quickly to form a watertight concrete plug at the site of the foundation damage.

1. cracked or damaged joint is necessary to embroider, to deepen, to give it the shape of the inside of the expanding cone.A solution
2. thick paste-like consistency, so that from it can be shaped blind plug holes in the concrete.All work should be carried out very quickly: mixing - no more than 2 minutes, sealing cracks or holes - 3 minutes.
3. Insert plug received in the gully and strongly pressed by hand or materials at hand for 1-2 minutes.During this time, the solution is grasped, and the active crystallization starts.
4. repaired surface is flattened by the scour solution joints and seams, and then treated with a solution of a permeated liquid waterproofing.

There are also tools used in the construction of reinforced concrete foundation: they are introduced in the ready-mixed concrete in the form of an aqueous solution in an amount raschtenom.Concrete additives such moisture resistant, mechanically durable, inert to aggressive liquids.

All work involving the application of penetrating waterproofing must be carried out in strong rubber gloves, glasses, avoiding contact with fluids and pastes to the skin.To repair the foundations of old buildings made of brick, concrete, natural stone is used as an injection penetrating insulation.
