One of the biggest challenges for the builder is the channelling of water and the protection of the structure against wear and tear caused by rain and weather. Civil engineering technology has brought us numerous waterproofing solutions that are now at your fingertips.

We know that you need to protect your project from water and corrosion, and that it can be a complex issue for non-experts. If you have any questions, we'll help you find the right waterproofing for your purposes. Go ahead!


  • The application of waterproofing generally takes place on roofs and high surfaces such as ceilings and terraces. Make sure you have adequate protection when working at heights.
  • There are 2 main types of waterproofing, which are classified on the basis of material: acrylic and asphalt. While the former are ideal for homes, the latter are more resistant to traffic and rain.
  • To choose the perfect waterproofing there are certain aspects to consider. Among them you should take into account the complexity of the installation, the interaction with the sun's rays and the performance per m².

What are waterproofing products and what advantages do they offer?

Waterproofing products are water-repellent compounds whose main function is to protect structures from water and corrosion. Some of them also offer protection against UV rays. Their application on roofs and certain structures is mandatory according to building regulations.

Once you have finished your waterproofing work, check the structure you have worked on regularly to detect possible faults during application and take preventive or corrective measures. Waterproofing is a job that can be done alone or in a team.

  • The structure ends with a uniform finish
  • Protects the structure extending its useful life
  • Ideal in regions with high rainfall
  • Prevents major damage such as leaks and leaks
  • The application process is rigorous and repetitive
  • The cost per square metre of construction rises
  • Risks of application at heights
  • Prevents transit through the area between 24 and 48 hours

Acrylic or Asphalt Waterproofing - What should you pay attention to?

Waterproofing methods are varied and there are different structures on the market. There are many ways to classify them, but perhaps the most common is to categorise them according to the base material. According to this classification there are 2 types of waterproofing: acrylic and asphalt.

Acrylic waterproofing. For roof structures of houses, courts and small buildings, the use of acrylic or hybrid waterproofing is generally recommended. This is simpler, but not as strong and is not recommended for large areas.

Asphalt waterproofing. There is also a popular method in areas of high rainfall, which involves the deployment and installation of sheets of asphalt material, which due to its thickness guarantees greater durability. It is also used when heavy foot traffic is anticipated.

Acrylic Waterproofing Asphalt Waterproofing
Surface type Low to medium traffic surfaces High traffic surfaces
Complexity of application Simple and flexible by one person Requires at least two persons
Finish Uniform without interruptions Shall have lines at overlaps of coats
Climate of the region For low or high rainfall areas For very high rainfall areas

Purchasing criteria

Choosing a product is not just about seeing the best price, or going by what the salesperson tells you. There are aspects that can guide you in this purchase, but what should you take into account to buy the waterproofing you need? Here are the most important features.

Performance in m2

Since you will be coating surfaces, you will want to know how much product you need to buy to reach your goal. Knowing this you can make perfect calculations regarding the amount you need to purchase to cover the space needed.

As a reference, take into account that each on average, in order to cover 1m2 of surface, you will require 1 to 1.3 litres of acrylic waterproofing. This may vary depending on the brand you wish to purchase. It is therefore advisable to read the product specifications carefully.

On the other hand, if you are looking for an asphalt membrane, consider that the rolls usually cover a standard of 8.7m2. Each brand has a different performance, but we suggest you check their specifications.

Light Reflection and UV Rays

Some of the waterproofing paints have reflective properties that prevent the energy of the sun's rays from wearing away their protective properties.

Check the specifications to see if the waterproofing product components include properties that disintegrate UV particles.

Additional installation resources

Each waterproofing has a particular application methodology. Check before you buy if you should supplement your purchase with a sealant, or if you should use heat to install the rolls of asphalt membrane.

Having determined the above will help you determine installation costs and times, as well as estimate appropriate safety measures. Remember that it is not only about inputs, but also about qualified personnel and specialised equipment in some cases.
