Twice Weathered Concrete Coping Stones

Twice weathered concrete coping stones protect and finish walls with a clean, professional look. A central peak sheds rainwater to both sides for balanced drainage, helping to prevent staining, frost damage and long-term deterioration. Ideal for garden walls, boundary walls, parapet walls and retaining walls, these copings combine durable performance with a neat, uniform wall cap.

Durable Dual-Slope Water Protection

Each twice weathered coping is formed with a peak around 75 mm high, tapering to 50 mm at both edges to drive water away. Underside drip grooves are positioned about 20 mm in from each edge to stop water tracking down the wall face. For best results, allow roughly a 30 mm overhang on each side during installation.

Decorative walls and long runs where a neat, uniform wall cap is preferred

Twice Weathered Coping Stones – FAQs

What is a twice weathered coping stone?

A twice weathered coping has a central ridge so rainwater falls to both sides. This gives balanced drainage for free-standing and boundary walls.

How wide should my coping stones be compared to the wall?

Allow around 30 mm overhang per side beyond the finished wall width so the drip grooves work properly and water is kept clear of the wall face.

Do Eurodec twice weathered copings include drip grooves?

Yes. Underside drip grooves are formed about 20 mm in from each edge to prevent water tracking down the wall. Maintain a clear overhang for best results.

What sizes and colours are available?

Common widths range from 280 mm to 600 mm at a 600 mm length, in Slate, Grey and Buff. Matching corner returns are available.

Are twice weathered copings suitable for parapets and retaining walls?

Yes. The dual-slope profile and drip grooves provide reliable weather protection for parapet walls and retaining walls when installed with the correct overhang.
