CemMend RainCote Products

The RainCote technology works by forming millions of fine crystalline fibers that find and fill the tunnel-like capillary pores when water is present in the concrete and the crystals will continue to grow long after the initial application when water finds it way into the concrete.

RainCote Products can be used as a waterproofing admix for fresh concrete (new construction) or it can be applied to aged concrete to permanently seal concrete surfaces.

RainCote Concrete Waterproofing

Product Description Applications Advantages Links

RainCote AdMix

A liquid concrete additive designed to make new cementitious installations permanently watertight.
  • Tunnels and subway systems
  • Foundations
  • Precast structures
  • Parking structures
  • Reservoirs
  • Sewage and water treatment plants
  • Swimming pools
  • Underground vaults
  • A liquid concrete additive designed to make new cementitious installations permanently watertight. 
  • Not a dry powder - easier and safer to mix; homogenous - no fear of clumping
  • May increase concrete strength
  • Resists extreme hydrostatic pressure, positive (active) or negative (passive) water pressure side
  • Can seal hairline cracks up to 1/64” (0.4 mm)
  • Becomes an integral part of the concrete
  • Not a vapor barrier - allows concrete to breathe
  • Maximum water/cement ratio of concrete should not exceed: 0.55
  • Negligible interference with water reducers and plasticizers
  • Negligible effect on slump
  • Negligible influence on air entrainment
  • Non toxic
  • Permanent
  • Less costly than most other methods

RainCote CP

A dry powder used to create a cementitious slurry for waterproofing the exterior surface of existing concrete and masonry above and below grade.
  • Specifically designed to waterproof the exterior surface of concrete and masonry above and below grade
  • Normally applied with a Tampico brush or can be spray applied
  • Not intended as a decorative finish coat
  • Used to waterproof foundations above or below grade or waterproof the back coating between face brick and back-up units
  • Waterproofs concrete and masonry surfaces above and below grade, interior and exterior, and positive and negative sides
  • Apply to concrete block, brick, stone, precast concrete or formed concrete
  • Apply to both positive and negative side (when hydro-static pressure is low and aesthetics are not important)

RainCote CP Dura-Plug

A specially engineered fast setting, non-shrink, strong, waterproofing cementitious material for concrete repair and water-proofing of concrete.
  • Sewer pipe
  • Manholes
  • Bridge decks
  • Parking structures
  • Dams
  • Piers
  • Industrial floors
  • Horizontal and formed vertical repairs
  • One component-easy to use
  • Shrinkage compensated-reduces early shrinkage
  • High early and ultimate compressive strength
  • Compatible modulus to concrete substrate
  • Freeze/thaw durable
  • Improved placement and workability
  • High density provides low permeability minimizing infiltration of water and deicing chemicals (salt/chlorides)

RainCote DWS

A liquid surface material which deeply penetrates concrete and mortar surfaces to waterproof, densify, harden and dustproof concrete an Portland Cement based material surfaces.
  • Liquid surface material deeply penetrates concrete and mortar surfaces to waterproof, densify, harden and dustproof concrete and Portland Cement based material surfaces
  • Helps achieve maximum strength and abrasion resistance of material surfaces without altering the natural appearance of the concrete
  • Hardens, waterproofs and toughens concrete and cement mortars for improved durability
  • Enhances adhesion capabilities to a wide variety of surfaces
  • Increases resistance to many industrial chemicals
  • May eliminate water curing
