Injection Waterproofing Applications

Stacks Image 62669

Underground Structures

WINE CELLARS
BASEMENTS
LIFT SHAFTS
VALVE CHAMBERS

No need to excavate around your structure to re-apply or repair traditional membranes. Simply seal floors, retaining walls and joints with high-pressure chemical structural injection from the interior of the structure. Guaranteed.

Cracks in Concrete

PARKING DECKS
COFFER CASTINGS
CONCRETE ROOF SLABS
RETAINER WALLS
CONCRETE COLUMNS

Structural repair and permanent water sealing of cracks and joints in concrete, made fast and permanent with high-pressure chemical injection waterproofing.

Retainer Walls

CONCRETE WALLS
REINFORCED CONCRETE WALLS
DOUBLE SKIN WALLS

Remedial injection waterproofing in walls, targeting cavities, honeycombing in casted concrete and cracks will prevent future water ingress into the core of the structure. That is without any structural changes.

Roof Slabs

CONCRETE ROOF SLABS

As long as your torch-on membrane is still in reasonable condition, injection waterproofing will stop future water leakage problems, without replacing the existing membrane. Fast, effective and guaranteed.
Alternatively we shall replace the old membrane with a new Polyurea membrane.

Frames

WINDOW AND DOOR FRAMES
ALUMINIUM FRAMES
WOODEN FRAMES

Remedial injection waterproofing in walls, targeting cavities, honeycombing in casted concrete and cracks will prevent future water ingress into the core of the structure. That is without any structural changes.

Concrete & Tiled Decks

TILED PATIOS
PARKING DECKS
PAVED DECKS

Unless you would like to replace your tiles, a fast and effective injection waterproofing solution will take care of your water ingress problems without removing any tiles or pavers.

Joints

EXPANSION JOINTS
CONSTRUCTION JOINTS

Chemical injection sealing of expansion joints will prevent future water ingress into the core of the structure. Sub-soil joints easily treated from the interior of the building.

Cavity Walls

CAVITY SEALING
RISING DAMP

Cavity wall waterproofing is a two part process. Cavity will first be primed with Poly2Flex and then filled with closed cell SPF to fill the cavity and provide insulation.


Silos

WATERPROOFING
GAS SEALING

Not only will we stop water ingress at small persistent areas, but we can also provide turnkey solutions for your water ingress in tunnels, round hoppers, through silo floors and walls. In addition to stopping water either above or below ground level, we can also pressure clean the interior of tubes to enable us to provide accurate pricing on repairs and internal gas sealing and waterproofing.

Benefits of Injection Waterproofing

Non-invasive - No need to chop tiles, break walls or excavate
Seamless membrane within the structure, blocking all porous areas and pathways
Particle size less than 1 Micron - extremely permeating
Saves cost due to the remarkable spread of Polymer grout - even at low injection pressure
Does not wash out during sealing - Stops leaks of 200 L/sec successfully
Exceptional performance under high pressure - successfully sealed static head of 20,000 kPa
Curing chemically controlled from several seconds to 48 hours
Seals saline and hypersaline water effectively
Remains flexible once solidified and will not re-leak with ground movement up to 400% elasticity.
Reaction is not exothermic - no expansion effect
Environmentally friendly - non hazardous

Interestingly enough during this sealing exercise another area that had been water stricken some 110m above had also dried up and is no longer a problem

Dry Environment = More Healthy Environment

On all of these occasions Liquid Waterproofing have been successful in effectively sealing these water intersections and allowed for the development of the haulages and crosscuts to continue in a timeous fashion

Polymer Chemical Injection Products

Poly2Flex

UltraC-P100

Poly2Flex can be classified as an emulsion grout. It is a patented polymer blend mixed with additives to promote flow and adhesion. It contains no toxic or hazardous materials other than 0.5% ammonia solution, which is present as a preservative but evaporates within minutes.

The reaction of Poly2Flex with water depends on the characteristics of the water, such as pH, salinity, mineral content, temperature etc.

The formulation of Poly2Flex can be varied to achieve the desired reaction with the specific water being treated. It is therefore essential to carry out tests with water from the area to be treated prior to finalising the formulation.

The rate of water flow as well as the texture of the flow area also influences the selection of the appropriate formulation of Poly2Flex.


High flows through large fissures or cracks require stability to achieve better penetration into the aquifer or crack before coagulation. Each case differs.

Poly2Flex can be used under very high pressures and are only limited by the grout pumps itself. Pressures of up to 50 Bar can easily be achieved.

Poly2Flex emulsion is also solidified with a chemical activator.


Poly2Flex can be used in wet or dry conditions.

DualFlex

HE-100

DualFlex is a dual component urethane and polymer based resin that reacts rapidly with equal proportions of water to form a flexible, impermeable foam with excellent adhesion to concrete and rock.


DualFlex is a low viscosity chemical grout primarily injected into the area of leakage, creating a mechanical and chemical bond, as well as a compression seal.

The cured resin is flexible and will resist degradation through thermal expansion and contraction, wet and dry cycles, and freeze and thaw cycles for long periods.

DualFlex is designed to fill and waterproof larger passages and honeycombing in structures and large cracks or joints in concrete

Excellent to fill and seal medium to large inaccessible areas in structures.


Stop infiltration through sewage systems, 
storm and drain culverts, manholes, utility vaults, large-diameter pipe or similar structures. 
Excellent for waterproofing in tunnels, elevator pits, dams, reservoirs, etc. 



DualFlex can be used in wet or dry conditions.
