Waterproofing Products: How To Choose The Best?

Choose the best products for waterproofing requires in-depth technical knowledge and a lot of research. It all starts with a well-done project, in which all the requirements of each structure are raised. Then, it will be possible to choose the best type and the best system for each case.

After that, comes the search for suppliers, which needs to be very broad and in-depth. Thus, you guarantee that you will have adequate support at every stage of your strategy. Do you want to know more? Follow up!

Do a waterproofing project with an expert

When planning a project or renovation, some plans are so important that we make a specific project for them to complement the main one. This allows for greater detail and focus. This is the case of the hydraulic and electrical projects.

However, other areas, such as sound insulation and waterproofing, do not receive special attention. However, they are equally essential for the satisfaction of your end customer and require specialized technical attention.

Nowadays, waterproofing technology has evolved considerably, with new techniques and materials. Thus, it became possible to apply waterproofing agents to practically all surfaces and to use certain additives to improve moisture resistance from many traditional materials.

When you do a project with someone who understands the subject, they will analyze the characteristics of the construction and understand where the main protection flaws may occur. Based on this, it is possible to choose the best strategies to prevent infiltration and the other related pathologies caused by humidity. Then, you will be able to choose the best products to apply in each case.

Opt for the best brands

However, even with a complete and efficient project, there is still a lot to do to ensure the quality of your waterproofing. The next step is to do research on the main product suppliers. To do this, you can ask your colleagues in the sector, check the reviews and comments on Google, or search for the company's page on social networks.

The following are some criteria that can be used at this time:

  • Inventory Capacity — the supplier must have a good quantity of goods available in their warehouse. In this way, delivery on time is guaranteed whenever any of your projects need it;
  • Materials Technology — nowadays, there are waterproofing agents very advanced, designed according to the best engineering discoveries. With this, you are able to meet all the requirements that your client wants;
  • abetting — it must also offer a support channel so that you can answer your questions and report any problems.
    Given this data, check which brands stand out on various criteria instead of selecting only by price. Often, choosing a bad supplier brings very high costs in the future, as your company will need to repair damage to clients' properties.

Give preference to direct purchases with the manufacturer

Buying direct from the manufacturer has several benefits. Firstly, it will have a much more aggressive inventory, as it needs to supply several resellers. In addition, they need to invest heavily in product quality, considering that the end customer has direct contact with them. So, if there are any persistent problems, the brand image would be greatly compromised.

However, the biggest advantage is the cost-benefit ratio. When you buy with a retailer, various costs are embedded within the product price, such as store rent, sellers' salaries, and other fixed costs.

Choose the right type of waterproofing for your project

There are two main types of waterproofing: rigid and flexible. The techniques, the applications, the materials, and the scope of each of them are very different from each other. Therefore, the ideal is to list already in the project those areas that would benefit the most from each of them and then look for the most appropriate system.

Rigid Waterproofing

This type of waterproofing is aimed at structures that do not undergo movements, be they torsion or flexion. For this reason, it is widely used in foundations and wall plinths. Generally, it is not applied under surfaces, but as an additive in construction inputs, such as plaster And the mortar. According to the indications of NBR 9575/2003, rigid waterproofing can be made from the following materials:

  • waterproof mortar with a water-repellent additive;
  • polymer mortar;
  • polymer-modified mortar;
  • cement mortar for Negative pressure;
  • polymer-modified cement.

Flexible Waterproofing

Flexible ones, on the other hand, have the capacity to adapt to deformations and absorb cracks. They can be applied both at the construction site and on prefabricated structures. Commonly, they are applied to surface of the material instead of being added to the mix. In this group, we have:

Get the right waterproofing system

Now that you know the types, I'm going to tell you a little bit about the waterproofing systems. They are the ones who will be in the product announcements. To make it easier to understand, I will show you which can be used in the rigid and the flexible.

Rigid Waterproofing:

  • Mortar Impermeable — is made on the flowerbed from hydrophobic additives (which repel water particles) in normal mortar;
  • Rigid Polymeric Mortar — the process of adding hydrophobes is carried out since manufacturing and it is ready for homogenization;

Flexible Waterproofing:

  • Asphalt Blanket — is produced with a core of polyester, polyethylene and PVC plastic compounds, covered with asphalt on both surfaces. It is ideal for large spaces;
  • Flexible Polymeric Mortars — they are applied to the construction site and are applied with applied plastic compounds.
    It is only possible to be successful in waterproofing when we obey the use of each material, apply it to the right structure and in the correct way. Otherwise, the risk of failure is too great and the supplier cannot be held responsible.

With these tips for the correct choice of products for waterproofing your work will have a great chance of success. The benefits are diverse: your customers will be satisfied and there will be a reduction in rework costs.
