SAP7 is a fine‑graded scoria aggregate widely used in drainage, landscaping, and bedding applications. Made up of naturally durable volcanic rock particles smaller than 7 mm, SAP7 combines excellent drainage performance, stability, and ease of use, making it a versatile material for both professional landscapers and DIY projects across New Zealand. It can serve decorative purposes, making it ideal for use around plants, in garden beds, or in pots. Key Features: Excellent Drainage: Its porous nature allows water to flow freely, making it suitable around pipes, drain coils, and in drainage trenches. Stable Bedding: Creates a firm, even layer beneath paving stones, concrete slabs, and other hardscapes, helping prevent settling and uneven surfaces. Natural Scoria Composition: Volcanic rock offers durability while remaining lightweight and easy to spread or compact. Versatile Use: Can be used under pavers, around drainage coils, behind retaining walls, or in landscaping beds.
