What Is Coping in Building Construction

Have you ever wondered how we at Dutum Construction Group create all those intricate, seamless joints in the structures we design and construct? The answer lies in the art of coping – the process of finishing the top or edge of a wall, parapet, or other masonry structure with a cap or cover, ensuring a perfect fit, and adding both aesthetic appeal and structural integrity to your building project. 

Building construction involves using various techniques and materials to ensure structural integrity, durability, and aesthetic appeal. One crucial aspect of building construction is coping, vital in protecting buildings from weathering and enhancing their visual appeal. 

In this article, we’ll explore the intricacies of coping in building construction, including its purposes and types, and why this process is an essential part of any successful building construction. 

What is Coping In Building Construction?

Coping in building construction refers to capping or covering the top of a wall or parapet to protect it from moisture and weathering and to provide a finished appearance. It helps to remove moisture from the wall’s surface, preventing damage and enhancing the building’s overall look. 

Coping may be made of stone (capstone), brick, clay or terracotta, concrete or cast stone, tile, slate, wood, thatch, or various metals, including aluminum, copper, stainless steel, steel, and zinc. 

Purpose of Coping

The primary purpose of coping is fourfold:

1. Weatherproofing and Waterproofing: Coping prevents water from entering the building structure, thus reducing the risk of damage and structural issues. It helps protect the wall or structure from moisture, rain, and other weather-related damage, which can lead to deterioration over time.
2. Structural Reinforcement: 

Coping adds strength and stability to the structure, ensuring it can withstand harsh weather conditions and external forces.

3. Aesthetic Appeal: 

Coping enhances the visual appeal of a building, providing a finished, polished look. Coping can enhance the appearance of a building by providing a finished and polished look. It comes in various styles, materials, and finishes to complement the overall design.

4. Safety: 

Some types of coping, such as flat or rounded coping stones, can provide a safer edge on parapet walls or ledges, reducing the risk of accidents.

Types of Coping 

Based on their shapes

• Curved coping: In curved coping, as the name suggests, there is a curved or rounded projection that domes the wall. Generally, the highest part of the curve is in the middle and lower parts on both edges of a wall to ensure efficient discharge of water away from the wall. 
• Flat coping: This is the simplest type and consists of just a flat element above a wall. This type is not very effective in diverting away rainwater, instead, it is applied on roofs where it prevents water from staying. This coping may have chambered edges to add extra style.
• Hipped End coping: This type has a three-sided slope, which is more suitable for the edges and corners of the wall.
• Crenelated Coping: It is also termed as ‘battlemented coping,’ which is designed with alternative low and high segments. These types of coping can be seen generally in historical buildings.
• Saddle coping: Saddle coping slopes to either side of a central high point.  Saddle wall coping is similar to the hip roof that directs the water to either side of the wall. The walls are angled on both sides, with a ridge in the center. It is found mainly in garden walls and may have drip grooves for water flow.
• Wedge coping: Wedge or splayed coping slopes in a single direction. They have one way for water flow. It may direct water from one roof to another through a channel and let it fall into a gutter.
• Decorative coping: This is mainly done by stones and used for styling. It may be seen in old Roman buildings.

Types of coping based on the type of material used

• Brick Wall Coping
• Clay Wall Coping
• Terra Cotta Wall Coping
• Stone Wall Coping
• Concrete (Pre-Cast) Wall Coping
• Concrete (Cast-in-Situ) Wall Coping
• Stainless Steel Wall Coping
•  Zinc Wall Coping
• Tile Coping 

Coping is done in two ways: 

1. Single-Side Slope: A single side slope, refers to a type of slope or incline that occurs on one side of a surface, typically a road, embankment, or terrain feature. The slope is directed towards one side, and about 20mm of coping is projected outside the wall. There is also a semi-circular throating groove of 10mm at the bottom surface, which can discharge the rainwater efficiently.
2. Two-Side Slope: Here, the slope is directed towards both sides of a wall, and for about 20-100mm, the coping is projected out of the wall. This type also generally consists of a semi-circular throating. To avoid water seepage into the wall, use a damp proof course, DPC, with a minimum thickness of 15-25mm beneath the coping.

Benefits of Coping

• Enhanced structural integrity: Coping adds strength and stability to the structure, ensuring it can withstand harsh weather conditions and external forces
• Prevents Decay: Coping prevents the wall from decaying or developing mold due to rainwater by effectively directing the water away from the wall surfaces towards the ground. 
• Enhances Durability: Due to seepage prevention by coping, the inner wall isn’t affected by water. This keeps inner walls healthy and can extend the lifespan of construction and masonry walls.
• Aesthetic Appeal: Apart from being structurally beneficial, coping enhances the physical appearance of a building by providing an elegant finish  
• Low Maintenance: Properly constructed coping with standard materials like concrete and stone requires only minimal maintenance. It can withstand harsh weather conditions, so there is no need for frequent repairs or replacements. 
• Functionality: When short or low-height walls are finished with coping, they can function as seating spaces in outdoor areas. Without coping, such walls would be inconvenient and uncomfortable to sit on due to their generally rough surfaces, thus making them less functional.
• Protects Against Weather: Coping is a barrier against weather conditions such as rain, snow, and ice. This protection is crucial for maintaining the physical soundness of the building from moisture and water damage over the long term.
