How to waterproof your house

Many times, a bad waterproofing makes our homes have damp or even mold. Fighting to solve this problem should be a priority in any remodeling. It is useless to paint if it is not solved before. We will cover the problem temporarily but not the focus, which can lead to more serious constructive problems.

Waterproofing systems are a combination of materials that work together to prevent water seepage. When facing a remodeling it is important to assess whether it is necessary to treat the humidity and leave part of the price for it if so. The most important thing is to always attack the problem as soon as it is detected since waiting only makes it worse. The solution will be faster and less expensive as soon as possible. Prevention and maintenance are the key to the fight against humidity, do not forget.

Roof waterproofing

The ceilings are, without a doubt, one of the most important structures of a house. Leaks or leakage problems can cause significant damage to other structures in the house or affect the contents. Within the systems for waterproofing ceilings we find polymerized acrylic paints, colorless covers, PVC membranes, synthetic, asphaltic or polymeric.

The most efficient and usual system is the asphalt waterproofing membrane prior to priming, to ensure a good seal. Ideally, a professional will assess the best solution in each case.

Waterproofing interior floors

If the floor is properly leveled, a self-leveling liquid polyurethane waterproofing system can be installed, which allows the finish to be laid without adding thickness. If the floor is not properly leveled, you can previously put a self-leveling mortar before waterproofing and take the opportunity to fix that problem.

Terrace waterproofing

If the terrace has tiles or some other floor that can be raised, the ideal is to completely replace the finish. If moisture and penetration into the floor is recommended to remove the surface, redo the laying of the base concrete, apply the primer polymer and apply the waterproofing based on continuous membranes.

Waterproofing walls

After verifying the existence or not of cracks and cracks (those larger than 1 mm must be cleaned, primed and sealed with a hydraulic putty), a solution is to apply an acrylic fixative and an elastomeric waterproofing paint in not less than 2 layers. Walls can be repaired with polymeric mortars. These solutions against moisture are applied outside when there is a plaster and inside if the external wall is exposed brick. In fact, in the case of exposed bricks, there are special waterproofing materials, which retain the color of the brick.

Waterproof with paint with insulating polymers
It is a type of surface waterproofing using one or more layers of paint. It is more durable than other methods such as bitumen bases also applicable in layers.

Waterproof with a cement plaster
It is used for flooring but it is also possible to use it on walls.

Waterproofing floors with rolls of bituminous base
It is a widely used method for floors. Bituminous base rolls can be made by means of the adhesive method, with a roller, or by the so-called “pontoon” that requires a burner, usually of gas and that needs professional installation.

Waterproofing by filling
This method is used mostly under pavements, creating an insulating layer from a filling composed of different shredded materials such as mineral wool or flying concrete. The mixture becomes a water resistant gel when moisture reaches.
