Foundation Membrane: A Key Element in Building and Protecting the Structure
Building a house is a process full of challenges and decisions that significantly impact the durability and strength of the entire structure. One key element, often overlooked but playing a crucial role in maintaining the foundations in good condition, is the foundation membrane. In today's article, we will look at this unassuming material, focusing on the differences between 500g/m² and 400g/m² membranes and their appropriate applications.
What is a Foundation Membrane?
A foundation membrane is a material used for insulating and protecting the building's foundations from moisture and other external factors, such as mechanical damage, harmful effects of pests, and tree and shrub roots. It is installed on the external surface of the foundations, creating a barrier that prevents water from penetrating the structure. This is particularly important for buildings located in areas with high groundwater levels or exposed to frequent rainfall. When used in terrace or balcony areas, it prevents moisture from penetrating the concrete layer, equalizes hydrostatic pressure, and acts as a drainage layer, directing water seeping from the floor or gravel to drainage pipes.
Differences Between 500g/m² and 400g/m² Membranes
Thickness and Strength: The first difference between 500g/m² and 400g/m² membranes is their thickness and strength. Higher gram weight membranes are generally thicker and more durable, making them more resistant to mechanical damage and weather conditions.
Degree of Insulation: With higher gram weight, the effectiveness of moisture insulation typically increases. A 500g/m² membrane can provide slightly better moisture protection compared to a 400g/m² membrane, which may be crucial for buildings located in areas with high groundwater levels.
Application: Both 500g/m² and 400g/m² membranes have their applications in construction. However, the choice of the appropriate gram weight should consider specific local conditions and structural requirements. In areas with extreme moisture conditions, a higher gram weight membrane is recommended to ensure maximum moisture protection and prolong the foundations' durability.
Length: Both 500g/m² and 400g/m² waterproof membranes are available in various heights. Depending on the needs, we offer membranes in heights of 0.5 m, 1 m, 1.5 m, 2 m in rolls of 20 meters.
Summary
The waterproof membrane is an extremely important element of any construction, playing a key role in protecting foundations from moisture and other external factors. Choosing the right membrane, considering the differences in gram weights, can significantly impact the durability and strength of the entire structure. Before making a decision, it is advisable to consult a professional who can help select the best solution for the specific case.
