Concrete injections

Injections in concrete with foam and polyurethane resins WEBAC - Stop water infiltration

Field of use:

injections into wet and dry cracks
injections into very fine cracks
sealing cracks and fissures in concrete
sealing expansion joints
sealing of wastewater tanks, sewers, tunnels, dams
sealing pipe penetrations

The sealing works for wet joints and cracks in brick, concrete, etc. structures are performed by injections with foam and WEBAC polyurethane resins, to stop water infiltrations, using the following materials:

Polyurethane resin foam is used to quickly and temporarily close and seal cracks and voids in water pipes with hydrostatic pressure, to fill cavities and gaps in concrete, masonry and natural stone structures, to seal water tanks, canals, sewers or other structures in hydraulic and well constructions, etc.
Flexible polyurethane resin for injections, used for flexible closing, sealing and filling of dry, wet or water-covered cracks and horizontal sealing against the creation of condensation in masonry, in works in stone quarries, natural stone constructions and in combination with masonry.

A special project made by us is the lock from Agigea in which you can see the differences before and after the procedure of inserting injections into the cracks

WEBAC - Germany

Protections against water, injections in wet and dry cracks, injections in very fine cracks, sealing cracks and fissures in concrete, sealing expansion joints, sealing wastewater tanks, sewers, tunnels, dams, sealing pipe penetrations.

Advantages:

the possibility of applying them on the opposite side of the building;
very deep penetration into small cracks for waterproofing;
increase the volume by foaming up to 40 times to fill cavities and gaps;
adjustable curing time;
very good adhesion to wet surfaces;
underwater injection possibilities;
good elasticity, allowing the movement of structures;
stable after drying, with constant volume, without contractions;
incorporates the crumbs;
approved for contact with drinking water;
easy to handle;
tolerates variations in mixing ratio and working conditions;
all materials in the system are compatible;
does not create new cracks.
