What are coping stones?
Coping stones are protective caps placed on top of walls, parapets or flat roof edges. Their main purpose is to protect the wall beneath from rainwater and weather damage.
They are usually designed with a sloped (weathered) surface and drip grooves so that rainwater runs away from the wall instead of down the face of the masonry. This helps prevent water penetration, staining, and long-term structural damage.

How do you install coping stones?
Coping stones are typically installed on top of a wall using mortar or a specialist adhesive. For taller walls or exposed roof areas, coping stones may also require mechanical fixings to provide additional security against wind uplift.

What is the difference between single weathered and twice weathered coping stones?
The difference is the direction of the slope on the top of the coping stone.
Twice weathered coping stones:
Twice weathered coping stones are generally the most popular option because they protect both sides of the wall equally.
How much overhang should coping stones have?
Coping stones should normally overhang the wall by 25-40mm on each side, but we recommend following the manufacturer's recommendations.
The overhang is important because it allows rainwater to drip away from the wall rather than running down the face of the masonry. Most coping stones also include drip grooves underneath, which further help direct water away and prevent staining or water damage.
What material is best for coping stones?
The best coping stone material depends on the style of the project and budget, plus your own personal preference.
