COMING OF WATER
Infiltrations may come from different sources:
• between concrete foundations and walls in elevation
• between predalles and vertical walls
• near passing pieces and wasp nests
• caused by static or dynamic cracks
• near discontinuities
• between joints
• between vertical walls and landings
• through tension bar heads
GAIA SOLUTIONS
Injection resisns
GAIA has designed two injection resins with which
it is possible to definitely seal all infiltrations in concrete
structures..
• PU
555 monocomponent polyurethane resin for injection
• Acrylflex
bicomponent acrylic resin for injection

Equipment anc accessories
Mono and bicomponent manual pumps ready for use, injection pumps,
accessories and spare parts for a 360° assistance.
INJECTION RESINS
• permanently seal infiltrations in concrete structures
• insoluble in water, non toxic and stable in time
• exceptional resistance against chemical agents, alkalii
and hydrocarbons
• regulable catalyzation speed
The resins are normally used to seal infiltrations, cracks and
faulty joints in all concrete structures, both vertical and horizontal,
old and new such as:
foundations, against ground walls, basements, lift pits, marine
works, civil and military engineering like bridges, dams, bunkers,
depuration plants, sewages, water containment tanks, swimming
pools, fire-fighting tanks, potable water tanks, hydric ducts,
irrigation channels, tunnels, underground passages.
PU
555
Monocomponent polyurethane resin
PU 555
is a monocomponent resin based on polyurethane and designed to
permanently seal water infiltrations in all concrete structures.
The resin PU
555 has a high expansion and is capable of sealing
cavities and wasp nests.
Acrylflex
Acrylic bicomponent resin
Acrylflex
is a bicomponent resin dased on acrylic and designed to permanently
seal water infiltrations in all concrete structures. Being very
fluid with low viscosity, the resin Acrylflex
deeply penetrates in the structure and waterproofs microcracks
and microfaults remaining ielastic in time.
WATER INFILTRATIONS: SOME PROBLEMS AND SOLUTIONS
Infiltrations along construction joints and along cracks
Seal the construction joints and along the cracks with injections
of Acrylflex/
PU 555.
The sealing thus realized is elastic and allows micro movements
to the structure..
Infiltrations through the nests present in the concrete
castingso
Demolish the nests to the healthy concrete, waterproof the area
and repair the demolished parts with the structural and waterproof
mortar CR
45 RS, resistant to sulfates.
Sealing of tension bars
Seal all around the bar head with injections of Acrylflex/
PU 555
Technical problem of iron support corrosion
The phenomenon of iron support corrosion is reduced by internally
blocking water in the structure. The use of the corrosion inhibitor
MC 200 allows
to give back a protection against corrosion to iron supports.
