Waterproofing (surface application)
Wide variety of treatments is commercially available for surface-applications in waterproofing treatment for concrete structures that is used to protect against the ingress of water.

Some applications come as dry powder that when mixed with water becomes a coating that is applied to the inner & outer sides of a concrete structure. These can be applied by hand brush or hand roller or by pressure spray guns.

Pressure Guniting.
To many construction people the word Guniting is used interchangeably with “shotcrete”.

What is Guniting?
The term, “Guniting” was used to describe a newly developed technique in US in which concrete (dry or wet) was used to be sprayed under pressure through a spray-gun at high velocity onto a civil construction surface. Since the material was sprayed through a gun, the term gunite seems to have surfaced.

It is Guniting when concrete shot is dry......
The dry-mix procedure involves mixing cement and aggregates (fine or both fine & coarse aggregates) totally dry in a bin, rig etc and then pumping the same through a hose or pipe pneumatically (using compressed air by a high powered compressor) under high pressure to a nozzle (the spray-gun).  Water is introduced to the dry mix only at the nozzle (by means of a water feeding line) just before the mix blasts off the nozzle at a high velocity onto the civil construction surface being treated.

It is shotcrete when concrete shot is wet.......
It is Shotcrete when the wet-mix procedure involves spraying of a pre-mixed or ready-mixed (wet) concrete or mortar under high pressure and at high velocity eliminating the need of adding any water in the nozzle or the spray-gun. 

Membrane pasting.
ZYCOPRIME forms water resistant cementations bonding coat and reduces porosity of structure. It acts as an excellent bonding agent for improving adhesion of concrete / plaster on Zycosil treated surfaces (plaster / slab)

Applications
Cementations work like plaster, screed on horizontal and vertical surfaces viz. roofs, sunken areas, tiling, retaining walls.

ELASTOBAR is used to form on-site seamless cross linked elastomeric membrane barrier on the concrete. It seals micro / macro cracks and pores. Cracks can be filled by mixing with cement and sand. The 100% acrylic composition ensures excellent UV stability, high strength and elongation 200-250%.

Applications
Slab Roof Terrace, Sunken, Balconies & Utilities, Podiums, Water Tanks and STP (Sewage Treatment Plants), Basements, Retaining Walls, Water Reservoirs etc.

For steel anti corrosion chemical application
Steel Anti-corrosion refers to the fortification & protection of metal surfaces from corroding in high-risk (corrosive) surroundings.
When metallic equipment & supplies are put into corrosive settings, they are likely to have chemical reactions with the air and/or water. The effects of corrosion become obvious on the outside exteriors of these materials. For example, after keeping iron in a corrosive environment for a long period, the iron starts rusting due to oxygen interaction with water on the iron's surface.

As a result of this, metal equipment missing any preventive (anti-corrosive) measures, may happen to get rusted both inside and out, depending upon atmospheric settings and how much of that equipment is exposed to the open air. Anti-corrosion measures are of particular importance in environments where high humidity, mist, and salt are factors, such as coastal places like Goa which has high salt content around beach areas and is always high in humidity.
