Joint Sealants

Sikaflex PRO-3

impregnated with bitumen emulsion for use as an expansion joint filler. Available in sheet form or cut to size. Manufactured to BS1142. Sikaflex® PRO-3 is a 1-component, moisture- curing, elastic joint sealant with high mechanical and chemical resistance.

Uses
Sikaflex® PRO-3 is designed for movement and connection joints in floors, pedestrian and traffic areas (e.g. parking decks, car parks), warehouses and production areas, applications in the food industry, sewage treatment plants, tunnel construction and in cleanrooms.

Advantages
• Movement capability of ± 35% (ASTM C 719)
• Very high mechanical and chemical resistance
• Bubble-free curing
• Good adhesion to most construction materials
• Solvent-free
• Very low emission

Thioflex 600 Polysulphide Sealant

Thioflex 600 is available in gun and pouring grades. The gun grade is ideal for general application. It is packed in a ready to mix, 2.5 litre tin containing the base and curing agent in the correct proportions. The pouring grade for joints in horizontal surfaces is supplied in 5 litre packs with the base and curing agent in separate tins. Thioflex 600 is particularly recommended for use in high-rise buildings and other applications where access for subsequent maintenance will be difficult and the risk of early movement failure must be minimised. It is also suitable for sealing joints in brickwork, retaining walls, basements and subways. Thioflex 600 pouring grade is recommended for initial sealing of expansion joints and stress relief joints in floors and sealing other horizontal surfaces.

Uses
Sealing movement joints in building and civil engineering structures, including superstructures, floors, basements and subways.

Advantages
• Meets key international standards
• Forms a tough, elastic, rubber-like seal
• Accommodates continuous and pronounced cyclic movement
• Excellent adhesion to most common substrates, including primed concrete, glass, aluminium and stainless steel
• High resistance to ageing reduces physical damage due to climatic extremes

Fosroc Colpor 200PF

Cold applied, high performance, pavement joint sealant conforming to the requirements of BS EN 14188-2:2004 and BS5212 Part1:1990 Colpor 200PF is a two component cold applied pouring grade sealant for pavement joints. It is flow applied into the joint either directly from the can or using a Fosroc G Gun. Colpor 200PF retains its movement accommodation of 25% on butt joints throughout the extremes of temperature, it does not harden in cold weather nor become excessively soft,or pick up in hot conditions. Colpor 200PF is resistant to jet blast and is suitable for concrete runways and hardstandings. Colpor 200PF is suitable for areas where fuel spillage is likely. In trafficked areas the maximum expansion joint width should not exceed 30 mm, wider joints are likely to suffer mechanical damage.

It is necessary to recess the level of the sealant 5 to 8 mm below the pavement surface, the depth is dependent on the season and temperature at the time of sealing. Additional protection for the joint aris can be provided by chamfering the top edge.

Uses
For the sealing and maintenance of joints in concrete roads, concrete runways and hard standings. Colpor 200PF is particularly suitable for sealing areas where fuel and oil spillage might occur such as aircraft hardstanding areas, oil terminals, garage forecourts, parking and cargo bays.

Advantages
• High durability and long service life
• High movement accommodation
• Cold applied — no heating equipment required
• Fuel, oil and hydraulic fluid resistance
• Jet blast resistant
