GUIDE ON THE APPLICATION OF INJECTION MATERIALS 3
4. Terms and definitions
4.1. Crack – a concrete structure defect that may occur
during construction or may result from a structural failure or
damage.
4.2. Active crack - a crack that changes its opening during
application of temporary or temperature loads.
4.3. Filtering crack - a crack that has traces of water
presence or demonstrates water filtration presence.
4.4. Technological (working) joint - a joint at the point of
contact of concrete of different ages that results from the
technology of concrete works.
4.5. Deformation joint - a moving joint in concrete and
reinforced concrete structures, which is a special gap
between two mating elements that allows to compensate
various kinds of deformations (thermal, sedimentary, etc.).
4.6. Waterproofing membrane - an insulation system
element designed to protect underground parts of
buildings, structures or their elements from groundwater
and surface water, atmospheric precipitation and
aggressive effects of surrounding soils.
4.7. Defect - a separate discrepancy between structures,
including building materials, to some parameter set by the
project or a regulatory document.
5. General requirements
5.1. Repair of reinforced concrete structures is carried out
both at the construction stage and during their operation.
Atthe construction stage, defects are usually eliminated
and cracks are treated. At the operation stage, various
types of repair works are carried out, including repairs for
eliminating water penetration through cracks and working
joints of concreting.
5.2. For effective repairing reinforced concrete structures
at the operation stage, It is necessary to develop a step-
by-step plan based on the results of on-site surveys,
the operating conditions of the facility and data on the
properties of materials that can be used for repairs.
5.3. Performing the injection works is allowed at base and
ambient temperatures from +5°C to +30°C. If necessary,
concrete should be heated using hot air blowers and
infrared heaters.
5.4. If necessary, before starting injection, the working
area must be protected from dust and water, for example,
using a PE film, access to cracks must be prepared and
connections for equipment and power tools, as well as
lighting must be provided.
5.5. Visible defects on the concrete surface (cavities,
porous areas) must be repaired prior to starting injection
works using repair compounds.
5.6. In case of a strong pressure of water fl ow in a joint
cavity, water suppression should be carried out by arranging
a cutoff wall before starting repair works.
5.7. For preparing the work area, the following
equipment and tools shall be used: chisel, hammer, pick,
sledgehammer, scrapers, pitching chisel, crowbar, metal
and lint brushes, vibration drill, angle grinder, apparatus for
water jetting and sandblasting, industrial vacuum cleaner,
discs for cutting and grinding concrete.
5.8. In order to prepare compounds for performing
works, the following equipment and tools shall be
used: construction mixer, mixing containers, measuring
containers, weigh-scales. During injection works, the
following equipment and tools shall be used: brushes with
hard bristles, spatulas, trowels, rules, floats, sealant gun with
closed tube, hot air gun. injection pumps of various types,
air compressor for pneumatic pumps.

6. Materials used
6.1. LOGICBASE INJECT injection materials shall be applied as the main materials for waterproofing and protecting building
structures.
6.2. Compounds for protection and repair of concrete structures are divided into two groups:
— Adhesive-sealing closure group (AS) - materials that seal crack cavities, are adhesively bonded to the concrete surface
after polymerization and capable of taking up impacts from movements during movement of cracks;
— Compression-sealing closure group (CS) - materials that seal crack cavities due to their own swelling when absorbing
moisture, are compressively connected to structure concrete and capable of taking up impacts from movements during
movement of cracks and water pressure.
6.3. Classifi cation of compounds according to a closure attribute is shown in Table 1.1
Table 1.1. «Classification of compounds according to a closure attribute»
Material type Remark
Adhesive-sealing closure group
LOGICBASE INJECT PU 300
1K injection resin based on
a hydroactive polyurethane
with a short foaming time.
Applied for quickly bridging and sealing cracks with active water leaks under pressure. When
contacting with water for a short time, the material repeatedly increases in volume, forming
a foam with small closed pores. To ensure long-term water resistance and reliability upon
the application of a hydroactive foam, it is necessary to conduct an additional injection stage
using a polyurethane resin, which does not form foam and gives the compound strength and
durability.
Two-component
polyurethane injection
resins LOGICBASE INJECT
PU 305 2K
A product based on a polyurethane resin with low viscosity and without solvent content. Upon
the reaction with water, the substance forms a dense, waterproof, hard-elastic foam with a
fine-porous structure. On contact with water, an approximately 30-fold increase in volume is
achieved in a free space.
Two-component
polyurethane injection
resins LOGICBASE INJECT
PU 310 2K
They have a low viscosity and do not contain solvents. They are characterized by high
elasticity figures and excellent adhesion to most surfaces. This type of resins is used to bridge
moving cracks (from 0.2 mm), which provides strong sealing and protection against re-opening
even under conditions of drops in temperature and frequent changes in loads.
Compression-sealing closure group
Acrylate-based injection
gels LOGICBASE INJECT
ACRYL 500 F, S
The main feature of injection gels is their very low viscosity, which allows the material to
penetrate into the smallest water-bearing cracks. Such gels are able to absorb moisture,
increasing in volume and, as a result, filling possible voids that may appear during
deformations of structures. After polymerization, the damaged waterproofing is completely
restored. Solutions based on acrylate gels are best suited for arranging injection anti-filtering
curtains in underground parts of buildings, waterproofing large volumes of masonry, restoring
waterproofing and sealing deformation joints.
