Waterproofing & Roofing Specialists.
We use only high performance, waterproofing, providing a complete range of membranes for use in modern building and civil construction projects.
This reliable roof waterproofing system has been in use since 1981, and has an excellent reputation for quality and durability. An estimated 15 million square metres of waterproofing has been installed in Ireland alone.
PARALON 77 3 & 4MM UNDERLAY BITUMEN-POLYMER WATERPROOFING MEMBRANES
The membranes of the PARALON 77 series are obtained by calendering a compound based on distilled bitumen modified with polyproplenic resins and elastomeric polymers; the reinforcement, integrally synthetic, is a non-woven polyester obtained from a continuous yarn: this gives to the finished product similar mechanical characteristics in both longitudinal and transverse sense.
The use of the PARALON compound suitably modified gives PARALON 77 membranes excellent weathering resistance in any climatic conditions and in exposed membrane systems.
However, the PARALON 77 membranes may be painted with either the protective coatings of the ELASTOMUL series (available in various colours) or with PARWENOL 4882 ALLUMINIO. The underside is covered with the TERMOTENE® treatment, for a safer and more economic lay-out. The PARALON 77 series is produced in two types:
PARALON 77 AND PARALON 77 4mm, that are 3 and 4 mm thick respectively; they are supplied in rolls, provided with a cardboard core that ensures their indeformability during the transport and the unrolling on site.
The PARALON 77 MEMBRANES are suitable to general waterproofing works, are particularly recommended for:
- Waterproofing of flat, pitched, vaulted roofs, of both cast in situ and precast concrete, also insulated.
- Waterproofing of gullies and valleys.
- Vertical walls.
- Waterproofing of basement extra doses and underground premises.
- Underground pipelines and tanks
Refurbish the existing roof, improving the falls on the main roof and introducing falls in the gutters to improve drainage.
Strip the existing gutters and introduce tapered insulation boards, running 1m onto the main roof. Use existing, repaired felt coverings on the field area as a vapour control layer and install tapered insulation boards. Weather with Paralon 77, 3mm base sheet and Paralon ARD/HS mineral surfaced cap sheet to provide a 15 year materials and workmanship guarantee.
