TamSeal 800 is a high-performance, single component EVA polymer, flexible waterproofing membrane.

In large applications, TamSeal 800 can be spray applied using a dry rotor machine by hand or robotic spraying. For smaller applications it can be applied by brush.

TamSeal 800 provides a tough, durable, seamless, waterproofing membrane for many structures including tunnels, shafts and caverns.

STRENGTHS:

•     Fast and easy application particularly for complex underground geometries.
•     Waterproof: zero penetration beyond membrane when tested in accordance with BS EN 12390-8:2000.
•     TamSeal 800 is safe, non-toxic and should be handled as per other cementitious construction materials.
•     Excellent adhesion, bond to concrete and steel of 1.5MPa or greater when tested in accordance with BSEN ISO 4624:2003.
•     When sandwiched between layers of concrete, the double bond (Example: To the primary concrete substrate and overlying secondary concrete) enhances the waterproofing performance.
•     Tough and flexible and suitable for use with steel fibre sprayed concrete.
•     Fast initial curing time, tack free in 2 to 3 hours.
•     Fast complete curing time, can be over-coated with concrete after 24 hours.
•     Exhibits excellent crack bridging capabilities when tested in accordance with BS EN 1062-7: 2004, with capacity proportional to thickness and 150% elongation when tested against ASTM D412-06a.
•     TamSeal 800 is non-ignitable: Class E when fire tested against BS EN ISO 11925-2, single-flame source test.
•     Unlike conventional coatings, which require the concrete to cure for 7 – 28 days, TamSeal 800 can be applied to 24 hour old concrete to give immediate protection.
•     Can be connected to other waterproofing materials with standardised joint details.

IT IS IDEAL FOR:

ТamSeal 800 can be applied to a multitude of substrates and works most efficiently between two layers of structural concrete lining, in such situations as:

• Sprayed concrete tunnel and shaft linings
• Diaphragm wall and contiguous pile boxes
• Underground basements
• Sprayed concrete caverns
• Protecting concrete against aggressive water ingress in mines and excavations
• Water retaining structures

QUANTITY USED:

• 1 kg/m² approx. per mm of thickness

PACKAGING:

• 15 kg Bag
