Roof Garden Drainage Systems

A roof garden brings nature closer to living spaces — but without a proper drainage and waterproofing system, it can lead to leaks, dampness, and structural damage.

At Raspan Management Services, we design and implement complete drainage systems for roof gardens that combine aesthetic landscaping with strong structural protection. Our goal is to create green roofs that are beautiful, durable, and leak-free.

With years of experience in waterproofing and construction systems, our team ensures that every roof garden functions efficiently — draining water quickly while protecting the building beneath.

Why a Proper Drainage System Matters

Our Roof Garden Drainage System Includes

• Waterproofing Layer – A strong, flexible waterproof membrane (PVC, EPDM, or PU-based) preventing water seepage into the roof slab.
• Root Barrier Layer – Special sheets designed to block root penetration, protecting the waterproofing system below.
• Drainage Layer – Made from HDPE drain cells or geocomposite sheets, allowing excess water to flow freely toward outlets.
• Filter Layer – Prevents soil and sediments from clogging the drainage system.
• Soil & Plantation Layer – Engineered lightweight soil mix suitable for rooftop vegetation.
