LEAD
Lead is irreplaceable. It's unique properties result in a material that is waterproof, strong and yet easily workable. A material which when correctly used will last for literally hundreds of years. No modern product can match this combination of performance, practicality, durability and beauty.

ASPHALT
Mastic Asphalt has been perceived by many building managers as being an expensive alternative to other products on offer to them to carry out waterproofing works. However, subject to a number of issues to be established, Mastic Asphalt offers clients a versatile system, which is cost effective to maintain and service.

SINGLE PLY
Single Ply Roofing is a modern day solution for the construction of flat roofs that meet the stringent demands of both specifiers and building owners for reliability, durability and low maintenance. It is replacing the more traditional materials and methods known as built-up roofing.

FELT
Historically, flat roofs were constructed using traditional bitumen based felts. These felts have very little elasticity, and become brittle with age. This has been made worse over recent years due to the increased use of high insulation materials under these felts, which increases the roof movement through temperature changes.- especially between the hot days of summer, and the freezing temperatures of winter. To over come these basic problems, the designers added stronger reinforcement to the felt. Using mainly polyester, which is extremely strong and has the added benefit of resisting piercing. Unfortunately, however strong these materials are, they are limited in their durability by using a base material from oxidised bitumens, and are therefore still subject to the same deterioration when subjected to huge temperature ranges. The vastly altering building market, left the designers with two main problems to overcome. Firstly, Designing a material which is truly flexible and retains this flexibility throughout all temperature ranges. Secondly, Designing a material which has a longer life expectancy and retains the traditional methods of fixing. After years of development, it was found that by adding polymers (SBS) to the bitumen in the manufacturing process, this resulted in a felt which is capable of accommodating repeated thermal movement, without any deterioration, and hence the life expectancy of the material is greatly increased.
