Mapei PURTOP 1000

Description

Purtop 1000 is a two-component, solvent-free, pure polyurea membrane formulated in MAPEI R&D laboratories. It is applied by spray with a high-pressure, bi-mixer type pump to form waterproof coatings directly on-site. The product is grey and is suitable for contact with drinking water. It forms a continuous waterproof layer that adapts to any substrate shape without cracking, thanks to its exceptional tensile strength, tear strength, and crack-bridging capacity, even at low temperatures.

Advantages

Solvent-free and no VOC (volatile organic compounds).
Immediate waterproofing and set to light foot traffic.
Excellent tensile strength (> 20 N/mm² according to ISO 37).
Excellent tear strength (> 80 N/mm according to ISO 34-1).
High crack-bridging capacity, both static and dynamic, even at low temperatures.
Elongation capacity higher than 300% (ISO 37).
Excellent resistance to alkalis and diluted acids.
Quick reaction times by spray: gel time at +23°C takes approximately 6 seconds.
No reinforcement required.
Does not form overloads on load-bearing structures.
After reticulation, the product is completely inert.
Resistant to root penetration (certified by UAS in Weihenstephan-Triesdorf, Germany).

Uses

Waterproofing membranes on storage tanks, basins, hydraulic works, roof gardens, inverted roofs, metal sheet roofs, bridge and viaduct decks, and cisterns for drinking water. Suitable for both new and existing structures.
