Bedding

Definition

Bedding is a filling of mortar, putty, or other substances used to secure a firm bearing, often for stone or other building materials.

Purpose

Bedding provides a stable and secure base for building materials, ensuring they are properly supported and aligned. This is crucial in construction for maintaining the integrity and durability of structures. Bedding materials fill gaps and create an even surface, distributing loads evenly and preventing movement or shifting that could lead to structural issues. It also helps in sealing joints and preventing moisture ingress, which can cause damage over time.

Examples of Use

1. Bricklaying: Bedding mortar is used to lay bricks, ensuring each brick is securely positioned and aligned with adjacent bricks.
2. Tile Installation: Bedding mortar or adhesive is applied to secure tiles to floors or walls, providing a stable base and preventing tiles from shifting.
3. Stone Masonry: In stone masonry, a layer of bedding mortar is used to set stones, ensuring they have a firm and level bearing.
4. Paving: Bedding sand or mortar is used under paving stones or slabs to create a stable and level surface, ensuring even load distribution.

Related Terms

1. Mortar: A mixture of cement, lime, sand, and water used in construction to bond bricks, stones, and other materials.
2. Putty: A pliable substance used to fill and seal gaps, often used in glazing to secure glass panes in window frames.
3. Grout: A mixture used to fill the gaps between tiles after they have been set in bedding mortar or adhesive.
4. Substrate: The underlying layer or surface on which a building material is applied or laid.
5. Pointing: The finishing of mortar joints between bricks or stones to improve appearance and prevent water ingress.

Notes

• The choice of bedding material depends on the specific application and the type of materials being secured.
• Proper preparation of the bedding layer is crucial to ensure the stability and longevity of the construction.
• Bedding materials should be applied evenly and adequately to fill all gaps and provide a uniform bearing surface.
