Concrete Cutting

This industrial plant in Lethbridge required a new opening and doorway to be created in an existing cinder block wall to accommodate their workflow. As part of the project Gator saw cut the door opening from the existing cinder block wall and fabricated, supplied, and installed the supporting structural steel for the door opening. Gator will work with Clients to produce the end results that they are looking for using modern techniques, all while maintaining a high standard of safety and quality.

Planter Repairs

 

Our expertise in multiple areas of concrete played a significant role in Gator being awarded the repairs to this 18-storey residential tower. When originally constructed, the large planters on the front of the building were improperly built.  The planters were overhanging off the building with no structural support underneath and were constructed without proper waterproofing and drainage.  Multiple contractors over the years had tried repairing the planters with little to no success so the decision was made to do a full removal and restoration of the entire front and west side of the Calla building.  After the demolition of existing planters and removal of substrate we also had to remove the stairs.  One of the unique challenges we faced was the temporary bridges to the front of the building and individual apartments so that tenants were able to have safe access throughout construction as every attempt was made to minimize disruptions for the tenants. Excavation was required to an 8 ft depth to allow access for the waterproofing membrane installation on the exterior wall.  Gator then prepared all new subgrade for the planters along with an engineered cantilever off of the main building.  Each planter was approximately 25 ft long X 5 ft Wide X 5 ft high and were rebuilt with proper drainage complete with all new electrical for lighting and a new irrigation system.  New stairs and handrails were installed including waterproofing for all the patios on ground level.  Gator fixed over 1000 linear feet of crack and active water leaking with Kryton crystalline grout.  Our success on this project has provided Gator the opportunity to supply annual maintenance for the parkade.

Parkade Restoration

As the Prime Contractor on this multi level parkade restoration Gator was not only responsible for the concrete restoration and new waterproof membrane installation, but we oversaw the new electrical and new drainage requirements that were required to get this parkade back to pristine condition.  Gator began this project by removing any of the existing coating that remained on the surface and then repaired any of the delaminated areas and structural repairs that were required.  Once the concrete surface was repaired MasterSeal 2500 was installed to protect the concrete surfaces from freeze/thaw damage as well as protection against parking deck chemicals including gasoline, diesel fuel, oil and de-icing salts.

Concrete Slabwork – Remove and Replace

During the original construction by others of this warehouse, sections of the subbase were improperly installed, causing significant issues for the tenant such as, cracking and collapsing of slab on grade. For multiple years the property owner attempted to fix the issue by mud jacking problem areas but the problems continued, so the decision was made to remove and replace the sections of concrete where the issues were occurring.  After demolition of the existing slab, Gator dug up existing subbase and supplied a new compacted subbase.  Once the rebar was installed and formwork completed Gator supplied, placed and trowel finished the new concrete slab.

Concrete Slab Rehabilitation

Drainage problems and water pooling resulted in significant concrete deterioration along the garage door at this condominium complex.  After cutting away the existing concrete aprons we reinstalled 6000+ sq. ft of new concrete aprons and curbs as per the engineer’s design, maintaining tight tolerances in grades to alleviate future water pooling.

Expansion Joints

The expansion joints at this condominium parkade were failing and had reached the end of their life.  Installation of Emseal Expansion joint systems is one of the many services Gator has extensive experience in.  Proper prep work and installation are critical to achieving the expected service life from expansion joint systems.  Gator removed any loose particles and weak concrete in the joint area to ensure a sound concrete substrate for the installation.  Any spalling, chipped areas and uneven surfaces were repaired ensuring the joint faces were parallel for proper installation for the installation of the Emseal DMS joint system.

Structural Concrete Repairs

The structural stabilization and repairs of the Brooks Aqueduct, both a National and Provincial Historic site, remains to be one of the most unique of Gator’s Projects.  A number of years ago a roughly 500 m section of the Brooks Aqueduct was removed to build a road for the canal.  In doing so a large piece of concrete had struck a column and caused severe damage which was never repaired.  Gator installed 30 ft screw piles into the ground for support of new galvanized steel columns to support the weight of the aqueduct.  Repairs were made to multiple columns throughout the aqueduct including new pile caps and raker beams.  Gator also installed new fencing around a number of sections of the aqueduct. We were able to complete this work with minimal disruption to the existing marshlands and brought back life to a part of this historic landmark.

Traffic Coating

As part of the upgrades to the Brentwood LRT Station, Gator installed a performance coating designed to take heavy volumes of traffic and extend the life of the walkways for years to come. As a Master Builder / Master Contractor with BASF (the worlds largest chemical company), the MasterTop MMA products were selected for their self-leveling, quick curing, and decorative finishes. This provides an impervious flexible flooring system with the ability to handle the varied temperature swings we experience outdoors in Calgary.

Parkade Repair/ Waterproof Membrane

When the concrete began failing at this condominium parkade the deterioration was rapid and the concrete surfaces required significant repair.  Gators ability to cover multiple scopes of work was key to the successful completion of this project.  Concrete repairs were completed on the ramps, structural suspended slab, and topside through slab along with expansion joint and soffit repairs.  To extend the life of the structure MasterSeal 2500 was installed on all vehicular traffic areas and MasterSeal 1500 was installed on the pedestrian traffic areas.

Industrial Coating

Gator works in multiple sectors and is sensitive to the needs of each. One such sector is the food and beverage industry. These plants require a high standard of cleanliness and CFIA approved products. By using microbe/bio-etch cleaners Gator is able to clean existing concrete surfaces of all contaminants prior to beginning the prep process. Gator’s wide collection of concrete surface preparation machinery allows us to adapt our preparation process to successfully achieve the removal of existing flooring and provide above industry standard surface preparation prior to coating installation.  Any mechanical grinding/preparation is done using specialized dustless equipment to prevent unnecessary airborne contaminants. Executing any needed repairs on existing concrete is critical and Gator guarantees all repairs are accomplished before proceeding with the flooring system install. The final step in this process is then to apply a high quality, durable coating system which meets the clients particular requirements and budget to extend the life of the concrete and make cleaning easier and more efficient. Gator provided multiple shifts to maintain 24hr/day production to complete the work over a weekend to minimize impact to the plant operations.
