Waterproofing Membranes
Royston Membranes are reinforced rubberized bitumen based membranes which provide excellent tensile strength and puncture resistance. Royston? Membranes provide superior support and strength in the most demanding conditions with the added benefits of fast installation and lower traffic control costs. Royston? Membranes are made with state-of-the-art materials which increases the life expectancy and protects against structural damage caused by moisture permeation.
The standard size is 48 inches x 50 feet. Custom sizes are available.
