ADVANTAGE URETEK !

VERSATILITY

URETEK technology allows accurate surface realignment and repair of concrete slabs, by quite simply raising the slab back to the level it should be - and resupporting it!

Literally any settled slab of concrete in contact with the ground can be considered for re-levelling by The URETEK Method. For example:-

floors, building slabs (residential, commercial, industrial).
highways, roads and bridge approaches.
pavements, kerbs and gutters.
industrial hardstand.
driveways, ramps.
machinery bases.


Concrete that may have settled due to:-

compression of subbase, caused by:
initial poor compaction
overloading
vibration/ earthquake
ingress of water
slip/subsidence (including "mine subsidence")
erosion or scouring (Including broken water pipes)


Sunken slabs can be raised from 2 mm to over 300 mm. Suspect and voided areas can also be addressed, with only enough lift applied ( 1 / 2 mm to 1 mm ) to confirm stabilisation.

Liquid flow paths can be reinstated.

The URETEK Method, alone or in conjunction with URETEK Deep-Injection, will raise and relevel parts of, or entire, buildings and other structures.

Injected URETEK material aggressively fills any voids it finds, allowing the stabilisation of vibrating machinery bases, flexing crane rails and ÔpumpingÕ concrete road slabs.

CONVENIENCE

The URETEK Method is very efficient. The set-up time, injection procedure and curing time are accomplished, in full, in a matter of hours - rather than days or even weeks required for alternatives. URETEK material hardens to 90% of its full strength in only 15 minutes. Therefore, completing the project and returning the location to full usage, is accomplished quickly. The time required is remarkably shorter than for any other structural repair technique or alternative.

The works can be isolated, staged and/or completed outside business hours, as required. Generally, there is minimal disruption to business operations, even during URETEK works. There should be no need to vacate or even relocate.

Full vehicular (including forklift) access is available immediately upon completion.

Realignment is carried out cleanly and quietly, as a dry process. There is no demolition, no excavation and generally no consequential redecoration. No water, no fumes, no smell. Little or no cleanup is required.

In terms of both equipment and material , The URETEK Method is self-contained and compact - dramatically reducing time, manpower and construction vehicle needs. Each URETEK truck has its own crew amenities, 3-phase power supply and carries all necessary components and materials to complete daily projects.

ECONOMICAL

The cost of The URETEK Method compares most favourably with alternative correction procedures.

Further, as consequential redecoration costs are often avoided, substantial indirect savings can accrue because business/occupation can continue uninterrupted.

Where the subgrade or foundation may be subject to continuing settlement, The URETEK Method can still provide a solution. Should future monitoring detect movement, the same holes can be used for re-levelling again. In this way the substantial capital expense of replacement, or other alternatives, can be exchanged for programmed maintenance.

CONTROLLABILITY

The URETEK Method does not depend on hydraulic pressure to lift. The boundaries of the subsided areas to be raised are readily controlled, so there are fewer chances for slab cracking and breaking. Also minimal pumping pressure and and rapid curing of the URETEK material, reduces the amount of material escaping from slab edges and through unrelated voids and channels.

The controllability of the injection process makes possible fractional raising of slabs and provides multiple adjustment capability.

It is usually unnecessary for there to be a void under the slab to begin lifting.

STRUCTURAL

Very high lifting power, of up to 40 tonnes per square metre (400 KPa), can be delivered by The URETEK Method.

The small size of the injection holes avoids bottom breakout and structural weakening due to drilling.

URETEK material aggressively fills any voids it finds. It develops compressive strengths well in excess of most sub-bases and, with substantial tensile, flexural and shear strengths, is not subject to cracking, shrinkage, erosion or consolidation. It is unnecessary to over-lift to accommodate ÔgroutÕ shrinkage.

The expansion of URETEK resins into cracks and joints can provide a positive seal, helping to prevent water infiltration (but should not be considered an alternative to proper resealing of joints).

Expansion joints are not blocked up (as can all too easily occur with cement grouting) but remain functional.

ARCHITECTURAL

The small number and size of injection holes can allow injection through floor coverings (or along carpet edges) and finishes (including vinyl, tiles and parquetry), where removal may not be practical. The small holes are not unsightly and can be plugged or patched, often obviating the need to match internal or external finishes.

Internal walls affected by the settlement of a supporting floor slab can be stabilised and raised back to original levels, closing cracks.

The URETEK material is completely impervious and can seal existing damage where it contacts a waterproof membrane. In certain cases it has been used to restore a damp-proof membrane. In other cases, as thermal insulation.

RELIABILITY

The world-patented URETEK Method has been proven over nearly 30 years experience throughout Europe, UK, North America and Australasia.

Injected URETEK material is guaranteed for a period of ten years, against any significant shrinkage or deterioration but its life span is considered indefinite.

Injected URETEK material is stable, inert and therefore harmless to the water table and the environment.
