Bed mortar is a high-slump, cement-rich material used in construction, typically applied in a one-inch layer, to significantly improve the strength and reduce water seepage in joints, particularly in masonry construction.
Here's a breakdown of its properties and purpose:
-
Composition: Bed mortar typically has a high cement content, giving it enhanced bonding properties.
-
Application: It's applied in a relatively thick layer (approximately one inch) between masonry units, such as concrete blocks or bricks. This differs from typical mortar joints that are much thinner.
-
Key Benefits:
- Increased Strength: When properly applied, bed mortar can effectively double the tensile and shear strength of the joints. This is crucial for structural integrity.
- Reduced Seepage: The density and composition of bed mortar significantly minimize water seepage through lift joints, protecting the structure from water damage.
- Improved Bonding: The high cement content promotes a strong bond between the masonry units.
-
Typical Uses: Bed mortar is often used in:
- Masonry walls: Enhancing the structural performance of walls constructed from concrete blocks or bricks.
- Water-retaining structures: Reducing water leakage in tanks, dams, and other similar structures.
- Below-grade construction: Preventing water intrusion in foundations and basements.
In essence, bed mortar is a specialized mortar designed to create a robust and water-resistant joint in masonry construction, improving the overall performance and longevity of the structure.
