Foundation waterproofing with EPDM membranes

Waterproofing membranes made of EPDM (Ethylene Propylene Diene Monomer) Hidrostan are known for their high elasticity, UV resistance and durability. These properties make them ideal for use in harsh environmental conditions, maintaining their performance for decades. In addition, EPDM membranes Hidrostan are particularly suitable for applications in both horizontal and vertical foundations, offering a versatile solution for waterproofing.

Advantages of Using Large Formats

One of the main advantages of EPDM membranes Hidrostan is that they can be used with large formats. This brings several significant benefits:

1. Reduction in the Number of Joints: Using large membranes dramatically reduces the number of joints required to cover the foundation surface. Fewer joints mean fewer points potentially vulnerable to water infiltration.

2. Improved Installation Efficiency: Large-format membranes can cover larger areas with fewer steps, making the installation process faster and more efficient. This reduces labor costs and to a faster completion of the project.

3. Lower Risk of Infiltration: Joints are often the weakest points in any waterproofing system. By reducing the number of joints, the risk of infiltration is significantly decreased, improving the overall protection of the foundation.

Application of Horizontal and Vertical Waterproofing

EPDM membranes Hidrostan offer considerable flexibility in use, as they can be applied both horizontally and vertically. This is particularly useful for foundation waterproofing, which requires protection at the base as well as on the sides.

1. Horizontal Application: When applying the membrane to horizontal surfaces, such as foundation slabs, it is critical to ensure continuous and uniform coverage. The large size of EPDM membranes Hidrostan allows large areas to be covered with few joints, ensuring a continuous barrier against moisture.

2. Vertical Application: For vertical surfaces, such as foundation walls, EPDM membranes Hidrostan can be easily applied due to their flexibility and tensile strength. The membranes can be firmly attached to walls, providing lasting protection against water infiltration.

Installation Procedure

Installation of EPDM membranes Hidrostan requires attention to detail to ensure effective protection.

1. Surface Preparation: Foundation surfaces should be clean and free of debris. Any unevenness should be leveled to ensure a smooth and uniform surface.

2. Application of adhesive (if necessary): In some cases, it may be necessary to apply AC221 adhesive to improve membrane adhesion to the foundation surface.

3. Placing the Membrane: The EPDM membrane Hidrostan is unrolled and placed on the prepared surface. It is important to ensure that the membrane is well stretched and free of creases or air bubbles.

4. Welding of Joints: Joints between membranes must be welded ( CIDAC Sealant Extrusion) carefully to ensure a tight seal.

5. Protection of the Membrane: Once installed, the membrane must be protected from mechanical damage during subsequent stages of construction. This may include the use of protective layers
