Structure Systems

Epoxy Injection is a type of injection to repair breakdowns or holes in concrete structures such as columns, beams, and other foundations. Epoxy Injection will fill in the cracks to repair structural strength. It repairs cracks in concrete structures by injecting liquid epoxy into the cracks under high pressure. This ensures a high adhesive strength and compressive strength. The epoxy injection is mainly used to repair cracks in size from 0.3 mm to 5.0 mm, and is a highly efficient way for repair.

Concrete Repair is used to repair concrete, structures or buildings that have been damaged through breakdowns or water leakages, caused by overuse of concrete, inappropriately storing excess weight during construction, or inadequate bracing.

Concrete repairing, structure repairing or damaged building repairing.
Grouting can fill or repair concrete cavities that water leakages. Grouting is applied in liquid form and strengthens when dried. It helps to strengthen concrete by filling holes that are present and repairs water leakages. It does not condense or shrink.

Strengthening is a way to strengthen the structure of buildings and has several forms. With compression force, it enhances the strength and flexibility compressively. It adds toughness and allows structures to carry more weight onto each structural parts.

Slab Lift by Vigotext
Slab Lift by Vigotext is a quick, economical repair process for correcting settled or unstable concrete slabs or other solid surfaces. From pavements, to highways, and everything in between, Slab Lift by Vigotext is a fast, effective and economical solution for correcting settlement and instability.

How Slab Lift by Vigotext Works
Two polyurethane liquid components are mixed (Vigotext uses the latest and most advanced American Graco reactors) and injected under high pressure below the area or structure being repaired. The two liquids react with each other resulting in expansion (which exerts pressure to raise the slab) and hardening (which stops the slab settling again). The foam we use is manufactured by Cormix International, and is specially formulated to be very strong and long-lasting than competitors.

Advantages of Slab Lift by Vigotext
There are many advantages of Slab Lift by Vigotext as compared to other methods of repair. Foam jacking has primarily been used in the infrastructure and industrial markets, but is also suitable for the residential market

Cleanliness
Slab Lift by Vigotext is a clean concrete lifting and stabilization process. As the injection equipment is mechanically connected to the slab or structure, and mechanical seals engage when not injecting material, no loose material is introduced to the repair area.

Less Disruption
Slab Lift by Vigotext is quiet and the quickest process for stabilizing and raising settled concrete slabs. Due to the small hole size, drilling is fast and quiet, and there is virtually no noise associated with the injection process itself. The equipment for Slab Lift by Vigotext is self-contained in a box truck, which is typically parked away from the direct work location.

Immediate Traffic
Vehicular traffic may resume within 15 minutes after work is completed. This includes heavy loading such as pickups, trucks and industrial equipment like fork lifts.

Lightweight
The lightweight foam material reduces the burden on underlying soils, reducing the chances for resettlement. Even the highest density polyurethane foams used for Slab Lift by Vigotext are significantly lighter than alternative lifting and stabilization materials such as grouting. This reduces the amount of additional burden weight placed on the underlying soils.

Waterproof
High density polyurethane is waterproof, so treated slabs are thoroughly undersealed. Polyurethane can also be installed in water, so flow testing or water stop applications with active flows are not a problem. Because of the near-immediate curing, water stopping jobs are fast and easily tested on site to ensure efficacy of the repairs.

What Slab Lift by Vigotext Is Best For?
Slab Lift by Vigotext can be used in many scenarios. There are many times when foam jacking is the only repair process that will address a problem. Here are some of the times when foam jacking is best:

Large slabs
Large slabs (typically bigger than 10 square meters) are best repaired with Slab Lift because our specially formulated foam can travel under the entire slab from just one or two injection holes, creating a more diffuse lifting force than grout. This speeds up work and lessens the chance of cracking.

Heavy slabs
Because of the high expansion force and ability to spread under large areas of slabs and structures before expanding, the high density foam can lift extremely heavy slabs with ease. These include roadway slabs, bridge approaches, rail crossings and slabs with heavy loads, such as machinery bases and floors with backup battery power packs.

Indoor Applications
Due to the required machinery being housed within a box truck only hoses and the drilling of small, infrequent holes are required indoors. This results in a dustless environment with little disruption.

Load sensitive areas
Because high density foam is lightweight, there is very little additional weight transferred to the underlying soil due to Slab Lift by Vigotext. This helps to minimize the chances of further resettlement. Sand-based and cementitious grouts used for slab jacking or pressure grouting typically are heavy and contribute to an increased risk of resettlement

Soil Stabilization
The most common cause of slab settlement is inadequate compaction or bearing capacity of the underlying soils and many slab lifting jobs first require the addressing of this underlying problem. Vigotext, in partnership with Cormix International, have a number of solutions to fix this issue by using specially formulated resins that stabilizes the soil or substrate to give a firm foundation for Slab Lift by Vigotext.
