MasterSeal 501 Surface applied waterproofing for concrete

DESCRIPTION
The MasterSeal 501 waterproofing system
ensures a total and permanent solution to water
leakage, ingress, or seepage in concrete
structures or any cementitious substrate. The
formation and development of insoluble crystals
into water bearing capillaries and interstices
effectively blocks the further passage of water.
Supplied as a powder and mixed to a slurry
consistency with potable water. MasterSeal 501 is
applied directly to concrete, blockwork or cement
renders in areas where general waterproofing is
required. In powder form, the product may be
used as a dry shake on horizontal construction
joints.
MasterSeal 501 consists of a blend of moisture
activated chemicals, high grade silica aggregates
and selected cements.
Premixed powders consisting of selected Portland
cement blended with an activating chemical and
high-grade quartz.
TYPICAL APPLICATIONS
WATER RETAINING WATER EXCLUDING
 Water tanks / towers  Basements
 Reservoirs  Tunnels
 Water treatment work  Inspection pits
 Dams  Foundations
 Canals  Retaining walls
 Harbours  Lift shafts
 Concrete pipes  Construction joints

ADVANTAGES
 Provides total and permanent waterproofing
properties by becoming an integral part of the
structure to which it is applied. Active
ingredients will not delaminate, peel off or wear
away
 Protects concrete and reinforcement against
corrosive waterborne substances
 Crystalline action is reactivated by contact with
water providing permanent and continuous
protection
 Effective against both positive and negative
water pressure
