Delta Geo-Drain - Waterproofing And Drainage Membrane - Compact Protection and Drainage System

A four-ply material for use as a compact protection and drainage system for waterproofing in building construction. 

Features and benefits:

• The four-ply construction enables water to be drained off before reaching the waterproof coating.
• Suitable for vertical gas (methane and Radon) drainage when combined with a classical filtration gravel layer underneath the floor slab. The top apertures of the drainage sheet should be covered with a layer of gravel to enable the gas to escape into the ambient air without difficulty.
• Joints have a self-adhesive edge strip.
• Delta® dimpled sheets are rot-proof, resisting saline solutions, inorganic acids, alkalines, and polar liquids.
• They are proof against attack or modification by any of the minerals, humic acids, and bacterial catabolic products that naturally occur in the soil, as well as by bacteria, fungi, and micro-organisms.
• The response of all sheet types to soil or underground water is completely neutral, nor will they leach any harmful and/ or ecologically doubtful substances.
• Care should be taken to ensure that they are not permanently exposed to UV radiation.
