There are different solutions for waterproofing foundations and outdoor floors, as well as numerous products designed for each of them. We will therefore help you choose the most suitable one for your purpose.
What to consider when choosing waterproofing products for foundations and outdoor floors
Choosing a waterproofing product for foundations and outdoor floors is an important task in ensuring the durability and integrity of a building.
Below are some factors to consider when choosing the best waterproofing product for your needs.
Soil type
The type of soil on which the structure will be built is important when choosing a waterproofing product. For example, if the soil has a high clay content or consists mainly of sand, it may require a highly resistant waterproofing product to prevent water ingress.
Water table
This is the level of groundwater in the area where the structure has been built. A high level indicates that the water is permanently very close to the surface, and vice versa. For this reason, it is important to choose a waterproofing product that can withstand water pressure.
Climatic conditions
Climatic conditions are also important when choosing a waterproofing product. For example, if the area where the structure will be built has a hot, humid climate, it may require a waterproofing product that is resistant to mould and fungal growth.
Durability
It is important to choose a waterproofing product that is resistant to degradation and abrasion, as this will ensure that the structure remains waterproof for an extended period.
Application
When choosing a waterproofing product, it is important to consider how it will be applied. Some waterproofing products are spray-applied, while others are applied with a roller or brush. It is important to choose a waterproofing product that is easy to apply and has a fast drying time.
Cost
Cost is also an important factor to consider when choosing a waterproofing product. It is important to choose a product that offers good performance at a reasonable price.
Types of waterproofing products
One of the first steps is to understand the different materials and products available for waterproofing foundations and outdoor floors. The most common waterproofing products are:
- Bituminous membranes
- Non-bituminous membranes
- Waterproofing paints
- Bituminous felts
- Synthetic sheets
- Waterproofing and drainage sheets
- Protective tarpaulins and plastic sheeting
- Spray-applied cork
- Anti-mould products
- Bituminous tapes
- Single-colour geomembranes
- Protective sheets
- Water repellents
- Waterproofing products for porous surfaces
Characteristics of waterproofing products
All waterproofing products must be resistant to water, weathering and any aggressive acidic or alkaline substances. Interior waterproofing products must also be resistant to heat and steam. In addition, some products, such as acrylic rubber waterproofing products, offer additional benefits such as high viscosity, durability and high solar reflectance, which reduces perceived temperature by up to 20%.
Depending on the surface to be treated
To establish which type of material is most suitable for each project, you first need to determine which materials you are treating: whether brick, monocouche render, concrete, stone, granite or marble, you must choose the right product.
Prerequisites
Before applying the waterproofing product, it is important to clean the concrete surface to remove all debris, oil and adhering soil. In addition, if a membrane is to be applied, it is advisable to use adhesive tape to secure the edges. For projects that require groundwater to be drained away, a perimeter drainage system leading to a sump can be used, with a 100 mm diameter perforated pipe and a layer of gravel and geotextile to prevent the drainage system from becoming blocked.
Advanced waterproofing products
There are also advanced, more resistant waterproofing products on the market, such as waterproofing products that reduce external noise and can lower the temperature by up to 15 degrees. These products offer better protection against moisture, heat and street noise.
The best waterproofing systems for foundations and outdoor floors
Byond's R&D and innovation department has developed various products that its application team uses for waterproofing foundations and outdoor floors.
- Byopur self-levelling polyurea membrane is manually applied and fast-drying, and is used to waterproof concrete structures, roofs, terraces and even water tanks.
- Zoruflex® Imper is a non-absorbent, waterproof coating system with extremely strong adhesion to concrete and steel surfaces, consisting of a complex formulation of methyl methacrylate (MMA) monomer and natural aggregates in different colours, which can be applied immediately.
We also work with Vandex products in the Canary Islands, such as Vandex Expaseal W 2010 (a water-expanding waterstop designed to waterproof construction joints) and Vandex Uni Mortar 1, a cement-based waterproofing and repair mortar.
Conclusions
In summary, choosing the best waterproofing product for foundations and outdoor floors requires consideration of several factors, such as soil type, climatic conditions, durability, application and cost.
By taking these factors into account, it is possible to choose a waterproofing product that offers excellent protection against water ingress and ensures the durability and integrity of your building.
Waterproofing is an important part of building maintenance, so making the right decision is essential to protect the structure from potential damage caused by water and moisture.
