Why is it important to waterproof a terrace?

Terraces, especially those exposed to adverse weather conditions, are vulnerable to moisture. Water seeping through tile joints or cracks in the floor can cause serious structural problems over time. Water seepage not only affects the aesthetics of the deck, but can compromise beams, columns, walls and even electrical or plumbing fixtures, resulting in costly repairs and long-term damage.

Waterproofing without raising the floor of your terrace is an excellent option to protect your terrace without complications. With the advances in construction materials, today it is possible to apply effective solutions without the need for major works, which saves time and money.

Waterproofing options for terraces without raising the ground

Below, we explore some of the best solutions for waterproofing your terrace without having to raise the ground, which you can easily purchase from ParatuReforma:

Transparent film waterproofing

Transparent pellicular waterproofing is a popular choice for already paved terraces. This system creates an elastic membrane that covers the cracks and joints of the tiles, preventing water seepage. One of its great advantages is that it maintains the aesthetics of the terrace, since its application is almost invisible. In addition, its elasticity allows it to absorb small expansions of the substrate.

Advantages of transparent film waterproofing:

  • It does not alter the appearance of the terrace.
  • Fast application.
  • Resistant to small expansions.

Disadvantages transparent film waterproofing:

  • Not recommended in areas with high traffic.
  • Esthetics can be affected over time due to sun exposure and friction.

Transparent non-filming waterproofing

This transparent, non-filming waterproofing system penetrates the pores of the substrate without forming a visible layer on the surface. Ideal for terraces with little traffic, this method seals micro-cracks and prevents water absorption without modifying the aesthetics of the tiles.

Advantages of transparent non-film waterproofing:

  • Maintains the original appearance of the terrace.
  • High resistance to traffic.
  • Easy maintenance.

Disadvantages of transparent non-film waterproofing:

  • Does not cover large cracks.
  • On surfaces with a lot of expansion, micro-cracks may appear over time.

Asphalt cloth

The asphalt membrane is a traditional and effective method for waterproofing terraces without the need to raise the ground. It is a bituminous sheet that is adhered to the substrate using a blowtorch, creating a waterproof barrier. Although this system requires more time and care during installation, it is very effective in the long term.

Advantages of roofing felt:

  • Excellent protection against water.
  • Durability: resistant to extreme weather conditions.
  • Ideal for large surfaces.

Disadvantages of roofing felt:

  • Laborious process and requires technical expertise.
  • Less aesthetically pleasing, as asphalt fabrics are usually dark in color and have no decorative options.

Liquid polyurethane

Liquid polyurethane is one of the most effective materials for waterproofing terraces without raising the ground. It is applied as a liquid paint that, when dry, becomes a solid and flexible membrane. It is highly resistant to UV radiation and effectively protects against leaks.

Advantages of liquid polyurethane:

  • Resistant to sun and heavy rain.
  • Repairs cracks and small cracks.
  • Aesthetic finish: provides a uniform and smooth finish.

Disadvantages of liquid polyurethane:

  • It requires drying time and should not be walked on during the process.
  • In surfaces with many expansions, it can generate cracks.

Waterproofing paints

Waterproofing paints are a quick and economical option to protect terraces without the need to raise the floor. These paints create a protective layer on the surface, preventing water seepage through joints and small cracks. They are ideal for terraces with little traffic and aesthetic use.

Advantages of waterproofing paints:

  • Easy application by brush or roller.
  • Low cost and wide range of colors and finishes.
  • Ideal for small repairs.

Inconveniences of waterproofing paints:

  • Not recommended for high traffic areas.
  • Durability may be affected by constant exposure to extreme weather conditions.

Preliminary considerations before waterproofing

Before opting for any of these methods, it is important to properly prepare the deck surface. Be sure to follow these steps:

  • Thoroughly clean the terrace: Remove dust, dirt, moss or any residue that may affect the adhesion of the waterproofing material.
  • Repair cracks and crevices: If there are large cracks, it is important to repair them before applying any product.
  • Check drains and drains: Make sure drains are not clogged to avoid water accumulation.

How can I waterproof my terrace without raising the ground?

There are several effective solutions for waterproofing your terrace without having to raise the floor, such as film waterproofing, which creates an elastic membrane on the surface, or non-film waterproofing, which seals the pores of the tiles. You can also opt for traditional systems such as roofing felt or liquid polyurethane, which protect your terrace from leaks and dampness without complicated works. In ParatuReforma we offer these materials so that you can do it easily and effectively.

Is it necessary to repair the cracks before waterproofing the terrace?

Yes, it is critical to repair any cracks or crevices in the deck before applying the waterproofing system. If cracks are left untreated, water could seep through them, compromising the effectiveness of the waterproofing.

How long will my terrace waterproofing system last?

The life of the waterproofing system depends on the material chosen and the conditions to which the terrace is exposed. For example, systems such as liquid polyurethane or roofing felt usually last several years with proper maintenance. It is advisable to perform periodic inspections (every 6-12 months) and keep drains and drains clean to ensure the durability of the system.
