Waterproofing services

Water ingress increases the life cycle costs of the structure and reduce its durability. Stentor Enterprises provides water systems to match these – cementitious waterproofing, liquid waterproofing, pre – formed geo – membranes, injection resins, joint treatment supports and concrete admixtures.

• Good abrasion and chemical resistance

Areas of application

• Roof slabs,terraces,balconies,chajjas,parapet walls
• Old and new surfaces,vertical as well as horizontal surfaces
• Structures having complicated geometry like domes,arches,shells,folded plates,paraboloids,corrugated sheets
• Structures exposed to marine or saline atmosphere.

Epoxy grouts

Epoxy grouts are specified globally as premier products for demanding applications such as compressors, generators, pump bases and drive motors, tank bases, conveyors and column supports.

The product provides a stable interface between equipment and foundations because it features optimum load transfer and will withstand in-service temperatures of 1000º F (538º C).

Many contractors and owners have expressed the need for a grout that can be installed at low temperatures without delay in bringing equipment online. The grout that exhibits outstanding flow properties and compressive strength, even at near-freezing temperatures. The result is a faster return to service with reduced shutdown times.

The product offers a unique combination of application and performance benefits. It will achieve 4,300 psi (30 MPa) compressive strength at 8 hours, and greater than 16,000 psi (115 MPa) ultimate strength. Even under cold weather extremes it will reach 4,100 psi (28 MPa) at one day.  The one-component grout is easy to mix, has low odor and can be easily cleaned up with water.

Admixtures

Admixtures make concrete more flowable, more durable and stronger – and improve the eco-friendliness of concrete structures.

When laying the foundation, for example, these additives allowed an almost 5,500 cubic meter single concrete pour.

To ensure that the densely packed steel reinforcement bars at the base of the slab were coated quickly and completely within this short time, the concrete had to be particularly flowable. One further advantage of the admixture is that the concrete can be pumped to an altitude of 300 meters without problems.

Another major challenge is that immense amount of concrete is needed to cast the foundation. Because concrete generates heat while setting – a lot of concrete means a lot of heat. And the hotter concrete becomes, the faster it sets. This can create a serious problem: if the first poured layers set too quickly, the following layers cannot bond with them properly. The resulting concrete is neither homogeneous nor stable enough.

This high concrete quality also ensures that the construction material can cope with the huge pressure generated by the enormous height of the tower. Thanks to admixtures, the concrete withstands a pressure equivalent to the weight of a small car resting on an area the size of a big toe. This outstanding strength ensures a long lifetime for the concrete structure and makes for sustainable building usage.

Superplasticizers improve not only the structural properties of concrete, but also its eco-friendliness.

Because of its versatility, concrete is the most widely used man-made material. But it has one considerable disadvantage: it causes large amounts of climate damaging carbon dioxide (CO₂). This is because concrete consists mainly of cement, which in turn contains cement clinker, a material fired at almost 1,500 degrees Celsius and whose production requires enormous amounts of energy. Cement clinker accounts for about six to seven percent of global carbon emissions.

Using the concrete admixture, up to 50 percent of the cement clinker can be replaced with other materials. These materials include fly ash, a byproduct of coal-fueled electric power plants, or blast furnace slag obtained during steel production and recycled for these purposes. In this way, admixtures allow savings of up to 60 percent carbon in concrete production.

 Polyurethane flooring systems

These are  monolithic and seamless epoxy flooring systems normally installed at 1/4″-1/2″ thicknesses depending upon usage, chemicals introduced to flooring area and cleaning temperatures expected. These flooring systems are extremely tough and can handle the wear and tear of food processing and industrial applications.

Epoxy tile grouts

Epoxy grout has become more and more popular among tile contractors and builders. Unlike cement grout, which is made from a cementitious powder mix, epoxy grout is made from epoxy resins and a filler powder. The grout is extremely durable and completely stains proof. Regular grout isn’t waterproof, so unlike epoxy grout, it can absorb water when it’s wet and stain easily. If you’re tired of scrubbing the gunk off your grout, epoxy grout could be your solution.

Epoxy grout is made from two different resins mixed with filler, making it very waterproof and bettered suited to harsher cleaning products. Epoxy thin sets offer greater bond strength and chemical resistance than cementitious grouts.

Regular grout is very easy to shape in outside corners where tile wraps around a wall, curb or shower niche. It is harder to achieve the same effect with epoxy grout, since it takes a little longer to set up in the grout joint.
