Waterproofing of the basement with his own hands

Foundation - the foundation of the building, directly in contact with the ground, while most of it is in direct contact with the soil layers.The ground water and precipitation affect the foundation, at the same time is its erosion and destruction.Especially dangerous effects on wet basement sub-zero temperatures: freezing in the pores and microcracks, the water expands, cracks, dramatically reducing resistance foundation loads.The solution to this problem - the waterproofing of the foundation, in a private home it is quite possible to perform with his own hands.

Types of waterproofing and especially

In modern construction are various ways basement waterproofing:

• Obmazochnaya - treatment compositions of the foundation having a high resistance to moisture, such as bitumen or polymeric mastics;
• impregnation - treatment compositions having a high penetrating ability.They fill the capillaries and form the non-hygroscopic material layer having a thickness up to several tens of centimeters;
• Okleechnaya - pasting foundation roll materials treated with adhesives.They are surfaced, requiring heating or self-adhesive.
• mounted - waterproofing using studded geomembranes of polymeric fabric collected in a single moisture-proof surface.

Waterproofing with mastic

Mastics waterproofing the basement with his own hands made on the basis of bitumen or rubber with the addition of various additives that increase strength and elasticity: reinforcing fibers, plasticizers, tinting.Kohler added to the various layers of mastic applied to the degree of coverage of each layer was more prominently.Mastics produce single component - ready to use, or a two-component - requires mixing before application.

application technology:

1. surface must be clean of heavy dirt and old roll of waterproofing materials.Clean up traces of rust, paint, insulation of coating is optional.There mastic, which can not be applied to the dried surface - it's convenient for work in wet weather.
2. all sharp edges, the edges must be removed - they can damage the waterproofing layer with mechanical ground pressure.Shells and joints should wipe sand and cement mortar - it eliminates the formation of bubbles and improve adhesion of mastic.
3. the joints of vertical and horizontal surfaces are prepared as follows: with external chamfer angles, providing corner radius not less than 3 cm, inside corners equipped with fillet and reinforced with fiberglass.
4. surface primed with a special compound suitable for the applicable type of mastic, and then dried.Prepare a paste for application: mastic for hot application is heated, two-component - mixed.Apply the paste with a brush or roller, swabs direction - vertically.Surface waterproofing is applied in several layers, and before the application of each subsequent layer is required to allow the previous dry.
5. backfill produce soft ground, optimally - building sand: because of the property is well skip moisture, sand filling prevents stagnation of the groundwater in the basement.

variation of surface waterproofing is impregnation.It differs in that the compositions for impregnating waterproofing execution have the ability to penetrate deeply into the pores of the material, thereby creating an insulating layer is not leaky.

surface waterproofing is used to protect against capillary moisture.It has a low mechanical strength, and is not suitable for protection against ground water pressure and erosion.In this case, use a multilayer lining hydraulic seals foundation with his own hands.

Okleechnaya basement waterproofing

lining hydraulic seals made of roll materials with waterproofing impregnation, such as tar paper, or polymer films.Modern web materials for lining hydraulic seals have a reinforcement, to increase their tensile strength.

technology application roll materials:

1. Prepare for waterproofing foundation: clean from dust and debris, dried and treated with a primer suitable for bituminous waterproofing.Dry.
2. To lay the foundation waterproofing roll coated with one layer of bituminous mixture, which paste roll material.Strips of material glue lap further promazyvaya of mastic asphalt.The number of layers depends on the design of the hydrostatic pressure.
3. for sticking surfaced roll materials, having melted plastic layer requires a gas burner.Roll waterproofing slightly rolled, heated and pressed to the ground.Continuing to heat the roll, it is gradually rolled across the surface of the foundation.The bands are placed overlapping and at laying the next layer monitor to previous seams completely overlap.
4. Rolled waterproofing materials with self-adhesive layer is adhered to the pre-machined surface with no sharp edges, protrusions, shells.Joints additional polymer coat with mastic.

Mounted basement waterproofing

Modern materials for mounted waterproofing membrane is a thermoplastic coating with a profiled outer layer provides additional strength.The membrane inner layer allows for removal of moisture in the outer direction and a good protection against the ingress of groundwater.Moisture condenses on the layer of the spike and into the drainage system.Waterproofing membrane has good tensile strength and high elongation coefficient.

Mount Technology:

1. Prepare the surface of the basement, clean and level.
2. necessary to avoid contact with the membrane polymer waterproofing bituminous materials, fats and solvents, as well as foams, polystyrene, mounting foam.To avoid contact, you can isolate the surface of geotextile base.
3. In places of vertical and horizontal interfaces arrange fillets or strengthening of an additional layer of amplification of the compensation tape.
4. Stack mountable waterproofing bands overlap, prokleivaya layers using a hot air welding.
5. equip drainage system and perform backfill soil.

Select the type of waterproofing depends on several factors: the depth verhovodnyh groundwater, rainfall, site topography.In some cases, drainage construction is imperative.

To prevent condensation and ensure the longevity of the foundation is also recommended to perform insulation of the foundation.
