Primeseal MC two parts Epoxy Primer
Primeseal MC is a high performance, versatile,
two-part, water based, hydrostatic pressure resistant, waterproofing barrier
membrane coating suitable for most types of porous and semi-porous surfaces
including green (newly laid) hardened concrete and damp surfaces. It is
formulated for demanding waterproofing, sealing and priming applications
including: Waterproofs and seals damp and green (newly laid) hardened concrete.
Waterproofs negative (inside) surfaces. Waterproofs positive (outside)
surfaces. Waterproofs above and below grade surfaces. Low water vapour pressure
barrier. (Prevents or minimises bubbling of membranes due to vapour emissions
from the substrate). Waterproofs basements, retaining walls, lift wells,
cellars etc. Waterproofs tanks and water retaining structures, i.e. concrete or
cementitious structures. Excellent primer for subsequent Wrimco membranes,
paints and industrial coatings. Seals and primes timber floors prior to
applying waterproofing membranes and other coatings. Seals concrete floors before laying timber floors.
It is suitable for most construction surfaces
including: Concrete, green (newly laid) hardened concrete, cement,
cement render, brick, block work, masonry, Hebel, timber, FC sheeting, CFC
sheeting, plasterboard and painted or coated surfaces. Damp surfaces -
but freedom from standing, running, seeping water, saturated substrates and
continual dampness is essential.
Maxseal Flex Cementitious Membrane
Maxseal Flex is a coating with flexible and waterproofing properties that adheres to practically every surface such as concrete, natural and artificial stone, mortar plasters, bricks, concrete blocks, etc. subjected to both positive or negative high water pressure. Waterproof coating that adheres to common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks. Once applied and cured, Maxseal Felx provides a non-toxic, flexible and waterproof coating that adheres to those common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks. Waterproofing and protection of water retaining structures, such as drinking water tanks, reservoirs, water mains and swimming pools. Waterproofing of below-grade structures like basements, retaining walls, foundations, tunnels, galleries subjected to both positive or negative high water pressure. Internal and external waterproofing and protection of new and old buildings, facades against dampness, rain, pollution and aggressive environments. Waterproofing and protection of concrete against carbonation, freeze-thaw cycles, de-icing salts in highways and chlorine penetration in public works, irrigation channels, dams, retaining walls and water treatment plants, bridges, etc. Tile fixing and waterproofing of bathrooms, kitchens and other wet rooms in hotels, hospitals, offices and residential buildings, also suitable for exterior applications. Waterproofing of jardinieres, terraces and balconies under the pavement.
Maxseal Flex M
MAXSEAL FLEX-M is a one-component cement based mortar. Once mixed only with water, it provides a high-performance flexible coating, for waterproofing and protection of concrete against positive and negative pressure. APPLICATION FIELDS: Waterproofing and protection of water retaining structures, such as potable water tanks, reservoirs, dams, water channels, fountains and swimming pools. Waterproofing of below-grade structures like basements, retaining walls, foundations, tunnels, galleries subject to high negative water pressure. Waterproofing and protection of concrete in waste water treatment plants, settlement tanks, etc. Waterproofing and protection of concrete structures against carbonation, and marine environment, such as civil works, bridges, architectural buildings, residential facades, etc. Waterproofing and protection of concrete against soil salts and aggressive ground water, in underground jobs, foundations, etc. Waterproofing of roofs, terraces, balconies, etc. Waterproofing of window boxes, gardens and other surfaces subject to root penetration. Internal waterproofing of bathrooms, kitchens and other wet areas in hotels, hospitals, offices, residential buildings, etc. ADVANTAGES: Provides a fully-flexible coating which ensures complete waterproofing even in the most severe conditions, or high negative water pressure.
Internal Water Tank Waterproofing
For safety reasons, solvent based liquid applied membranes and
primers are best avoided. There is a potential problem with water based
membranes if the tank is filled even just a little before it has fully
cured, so care must be taken to ensure that this does not happen.
Urethane modified acrylics such as Wrimco supplied Pondseal are
particularly suited to ponds
with curved and rounded shapes.
Wrimco Hydrostatic pressure resistant, flexible cementious liquid membrane will also give good results.
For tanks that are rectangular, the best system is torch
applied Wrimco SBS supplemented by Alsan Flashing for around rungs set
in the concrete. Blockwork and concrete walls do not require priming but
the concrete base is normally primed with Wrimco 2-part Water Based
Epoxy (WBE) since torching uses up oxygen and creates CO2, it is best
done before the lid or top is installed unless there is excellent
ventilation provided and proper safety procedures are followed.
Tanks buried in wet ground may need protection from negative
pressures. In such cases, always prime with two parts WBE and use two coats
with blockwork because it is so porous. If permanently damp, wet
substrate Epoxy should be used. If there is visible water coming
through, drill or grind to open it up in order to pack in the plug.
External Water Tank Waterproofing
Obviously it is not a good idea for the walls of tanks to be
saturated with water as the rebar will rust and spoil the concrete,
commonly called concrete cancer. So when the tank is buried, waterproof
the outside same as you would do for a retaining wall and including
above ground especially for porous blockwork.
Large concrete water storage tanks which are normally above
ground frequently leak through cracks in the concrete. Waterproofing
internally may be too difficult or too costly. In such cases, concrete
injection is the answer. Holes are drilled at 45 degrees to the surface
to the centre of the wall at regular intervals, hoping to intersect the
crack. Special foaming urethane liquids are injected into the holes via
packers using a very high pressure, positive displacement pump. The
urethane reacts with the water to form a water tight foam that fills the
cracked and thus stops the leaks.
