FCM 80 is specifically designed for repairing cracks subject to movement, sealing construction joints, restoring deteriorated concrete, and waterproofing concrete structures. FCM 80 has exceptional adhesive and elongation characteristics and is often used in conjunction with the Xypex Crystalline Concrete Waterproofing and Protection System. FCM is a two component product consisting of a specialized liquid polymer dispersion and a cementitious powder. These components are mixed just prior to application.
Advantages of Xypex
- Superior elongation properties
- Excellent adhesive qualities
- Impermeable to water and chlorides
- Breathable, seamless
- Durable, retains properties in climatic extremes
- Non-toxic, solvent-free, odorless
- Effective when subjected to thermal contraction and expansion
- Moving Cracks
- Construction Joints
- Deteriorated Concrete Surfaces
- Concrete Block Walls
- Balconies, Terraces, and Planters
- Water-holding Structures
- Sewage and Water Treatment Tanks
- Marine Structures
- Thermal Contraction and Expansion
Xypex FCM 80 is packaged in a carton as a unit (kit), which includes the liquid component (1.06 U.S. gallon / 4 litre bottle) and the powder component (22 lb. / 10 kg pail). For larger projects, customized packaging is available; contact the manufacturer for details.
When mixed, one unit will cover an estimated 28 sq. ft. (2.6 m2) at a two-coat application thickness of 1/8 in. (3 mm).
Xypex products must be stored dry at a minimum temperature of 45ºF (7ºC). Shelf life is one year when stored under proper conditions.
FCM 80 Application Details
This report reviews the performance of the Xypex Concentrate / FCM 80 that was applied approximately 2.5 to 3 years prior to the site inspection. Now at 2.5 years post application the materials have exhibited excellent wear and physical properties with no sign of delamination, crazing or cracking of the applied material.
Cargo Centre Accra
This below grade carpark (basement), beneath the 10,000 m2 office block was waterproofed using Xypex Concentrate and Modified. The above grade joints, in the cargo area, were sealed and made watertight with Xypex FCM 80 and Patch’nPlug. Spray-applied bitumen was also considered for this project. However, unlike spray-applied bitumen, no final finish was required over the Xypex-treated concrete surfaces. This led to large project cost savings and in addition, two months of construction time was saved by choosing Xypex products. Xypex was previously used on the Bank of Ghana Cash Processing Center by the same construction firm “EnergoProjekt”. This repetition demonstrates their confidence in Xypex products.
Miller Highway Tunnel at 59th Street
Xypex Concentrate, Megamix II, Patch’n Plug and FCM 80 were used throughout the project to repair the current damage and to protect against future leaks. Xypex FCM 80 was specifically used in areas where there was expansion and contraction of cracks due to fluctuating weather conditions. To this day, and after heavy rain falls, the Xypex treated portion of the tunnel remains dry. Compared to alternative systems, approximate cost savings so far have been $1.5 million.
