Pros and cons of surface waterproofing

waterproofing Obmazochnaya usually consists of several layers.The thickness may be a few millimeters and a few centimeters.It depends on the condition of the surface being treated.

Benefits surface waterproofing

• protects the house from the inside and outside of the ground water, steam;
• increases the durability of buildings;
• work on its application simple and can be made with your own hands;
• protective surface is uniform, no joints;
• the possibility of putting on any surface;
• cheaper than other insulation materials;
• work takes a little time.

Disadvantages

• bad resistance to mechanical stress;
• waterproofing properties are lost if the house by the motorway and near the railway station, or near high-rise construction started.

Types of surface waterproofing

as surface waterproofing following compositions are used:

• bitumen.The cost of waterproofing in this low, but there is a drawback: it is brittle at low temperatures.When laying asphalt surface waterproofing, it must be heated to 120 degrees C. It serves no more than 6 years.Among other species - this is the cheapest;
• waterproofing obmazochnuyu having a bitumen-latex base.It is plastic, heating is not required during installation, easy to use, fire-proof, but in some cases, the base must be reinforced;
• synthetic resin.It's called bitumen-polymer.Very high quality, durable, work with it and can be sub-zero temperatures to -50 degrees C. deeply penetrates into the surface.Before applying the required meticulous preparation and priming;
• cement.It is economical, environmentally friendly, low-shrinkage, durable and easy to use.There is a but: need job skills, otherwise it is difficult to put right;
• mastic resin cement.Cement and synthetic components provide it a high adhesion to the surface and resistance to bending, so it is used on the ceilings.The surface before application is prepared.Price has enough high.

basement waterproofing

basement waterproofing obmazochnuyu perform necessary in any case, as it builds up the moisture from the soil, which is able to destroy it.

What material to choose

When selecting waterproofing, you must decide:

• with temperature control, which will prevail in the period when you want to work;
• where you will apply the material: on the outside or inside of the basement foundation to isolate;
• with an area the size that you want to isolate.On the basis of the area determines the flow rate;
• with loads of the treated part of the foundation.

types of waterproofing materials used for the foundation

Builders professionals divided into 3 types of waterproofing.One protivokapillyarny, and the other two - protivovodnye:

• easy.It is used where the water table is below the foundation level.Soils in this case, often sandy or sandy loam.The role of waterproofing - foundation to protect against capillary moisture;
• average.Designed for bases that were built on clay and loam, which hold moisture for a long time, not allowing her to leave at depth;
• heavy.The use of this type of waterproofing advisable where the ground water are high and have a constant pressure on the foundation.Apply the protection of at least 4 mm thick.Necessary glass fiber mesh reinforcement in two layers.

Note: classification of the material, which is used by experts may be indicated in some packages.

rules applying lubricant to the foundation waterproofing

purchasing a waterproofing liquid mixture, all the conditions stipulated by the manufacturer, and in addition:

• bears the sealing layer with a brush, roller or trowel;
• if a shower of rain, then proceed to work on the incident at least 4 hours;
• foundation surface as possible aligned, remove sharp edges, so as not to disturb the tightness of the coating;
• if protivokapillyarnaya waterproofing, then put it on a layer of 1 to 3 mm;
• waterproofing layer medium type sometimes up to 5 mm;
• depending on the characteristics of the heavy waterproofing mixture it was layered between 2 to 6 mm;
• sure that the layer has a uniform thickness over the entire area;
• hours at 10-12 layer should be something to protect from the sun or rain possible, and when he was a little grab, protect clean.Complete drying occurs within 2-3 days.

Important: in the process of applying the waterproofing is necessary to control its thickness.Measurements should be performed in dot diagonally.

Protect waterproofing

When will run backfilling the pit, there is a risk of waterproofing damage, so it is better to protect, at the same time: if the waterproofing mixture does not contain organic solvents, then as a defense used extruded or conventional polystyrene for light and medium waterproofingand profiled membrane - to severe.

successfully used for surface waterproofing basement waterproofing mixture Kreisel Dichtungsschlämme 810. Made in Germany:

• used both outside and inside;
• diluted with water.After cooking, should be implemented for two hours;
• applied at temperatures from 5 to 25 degrees C;
• made on the basis of Portland cement.Additive comprises a polymeric binding materials, mineral fillers, modifiers;
• for the drying of the first layer requires an hour 3. For the following layers of time can increase by 1 hour;
• focusing on operating conditions, a layer 2 to 5 mm;
• waterproofing quality strengthened if, before it is applied, the surface primed with acrylic primer facade from the same manufacturer.

surface waterproofing floor

surface waterproofing on the floor will protect the house from moisture, and if it is an apartment, it is necessary in the bath and as a protection against moisture, and as armor on you flood the neighbors.

preparatory stage

With the move to apply the insulation is not necessary.First:

• surface to be cleaned: dust remove the vacuum cleaner, clear the floor of all extraneous spots, in fact because of them can deteriorate adhesion;
• necessarily perform alignment.Valid only irregularities to 2 mm.If there is a large gap, then cementing them;
• install beacons and make leveling screed strip width of 2-3 m;

• when screed seize, apply a primer, using a brush or a spray gun;
• if you select surface waterproofing to the floor in a dry mix with a cement foundation, then dissolve it in water.The proportions indicated on the package.After 5 minutes the solution stir again.It should be uniform.

Application surface waterproofing

use solution based on cement is necessary for 1.5 hours, so proceed immediately:

• we put the first layer;
• 5 hours, you can proceed to the second layer.In this case, it is imposed perpendicularly to the first to the gaps between strokes was minimal;
• if the floor surface waterproofing composition is performed on the bitumen-latex or bitumen-polymer-based, then it is poured on top of the screed.

to when purchasing a waterproofing of coating, the price matched the quality, choose a trusted manufacturers.Good reviews of the two-component waterproofing lubricative elastic-plastic Litokol Coverflex from the Italian manufacturer Litokol:

• has a good grip both porous and dense with surfaces;
• basis of cement;
• chemical resistance;
• applied in two cross layers.The interval between the treatments - 3 hours if the room temperature is not lower than 23 degrees C;
• applied in the temperature range of 5-35 degrees C;
• on the application layer of 1 mm to 1 m sq.1.6 kg out of the mixture.
