Roof Waterproofing and Green Roof Solutions

Newton System 200 products offer solutions for waterproofing flat and inverted roofs, as well as green and turf roofs.

Newton 207 DeckDrain

Drainage Membrane for Flat Roofs

Newton 207 DeckDrain

Newton 207 DeckDrain is usually applied above Acriflex Winter where the finish above the membrane is permeable – such as when paving slabs are bedded on sand or with inverted warm roofs.

The double cuspated design provides two layers of drainage; allowing for primary drainage through the geotextile filter, as well as secondary drainage between the underside of 207 DeckDrain and the primary waterproofing layer.

Newton 207 DeckDrain provides a clear and clean drainage path for surface water to roof drainage outlets Read More…

Newton 220 Reservoir for Green Roofs

Newton 220 Reservoir

Newton 220 Reservoir is a unique drainage and water retention membrane for use where a water reservoir is required for extensive green roofs of sedum, herbaceous plants, mosses or grass above decks and roofs.

Unlike other products of this type, Newton 220 Reservoir has a bonded geotextile that prevents intrusion of the soil into the water holding cups during back-fill and compression.

This results in a permanently larger volume reservoir than any other 20mm deep green roof membrane. Read More…
