CERA INJECT SS is a single component, solvent free polyurethane based injection system for sealing and filling of joints, voids and cracks in Civil Engineering structures either under moisture or water bearing conditions.

Advantages:
  • Stops water leakage by injection from negative side
  • Environment friendly
  • Suitable for potable water tanks
  • Sealing and stabilisation of cracks in loose rock areas.
  • Ideal for sealing of leakages in diaphragm walls.

Function:
  • CERA INJECT SS when injected forms an effective sealing system which blocks the pores and cavities preventing seepage of water. CERA INJECT SS on contact with water reacts instantaneously and forms an effective compound which blocks the pores and the cracks.

Uses:
  • CERA INJECT SS helps to seal and stabilize cavities and cracks when used in loose rock and hard rocks.
  • CERA INJECT SS can be used for sealing of sheet pilings, diaphragm walls, tunnel walls and similar structures on ground water bearing conditions.
  • CERA INJECT SS can be used for arresting leakages in water bearing structures, tunnels, basements, cracks, drains and pipe sockets.

Method Of Application:
  • Preparation: Depending upon the conditions of the cracks and joints, which can be assessed by technical inspection, suitable injection packers have to be placed as per the relevant specifications.

Injection:
  • CERA INJECT SS shall be applied using a suitable injection pump capable of delivering the material at a sufficient pressure. The rate of injection, dilution, and working chambers, etc. will fully depend on the conditions of the cracks and voids. When the injected CERA INJECT SS comes in contact with water, it converts into rigid, closed-cell foam.

CERA GROUT 40 is a high strength non-shrink, pourable / pumpable grout for industrial applications. Premixed, selectively graded components result in a dense, homogenous mix, with excellent strength and dimensional stability.

Advantages:
  • Excellent fluidity for easy placements
  • Accessibility to remote parts of structure
  • One-step grout, Ready to use
  • High early strength and uniform set, minimizes downtime for repairs and maintenance, allows earlier loading
  • Dimensionally stable, needs no special treatment at open ends, capping or edges
  • No bleeding / segregation
  • Densification of material decreases permeability, increases wear resistance
  • Resistant to oils, chemicals etc
  • No efflorescence

Function:
  • CERA GROUT 40 develops a slight, but controlled expansion,m beginning at the time of placement, resulting in excellent dimensional stability. It ensures that no major voids are left even in areas that are remotely accessible. Because of its non- shrink characteristics, it remains stable in place without cracking, crumbling or delamination.

Uses:
  • CERA GROUT 40 can be used for grouting of precast structural members and to joints, dowels, rail posts and sealing bolts, powerline stanchions etc.
  • CERA GROUT 40 compensates for the normal shrinkage of concrete and mortar, absorbs, and minimizes the effects of vibration on foundation.
  • CERA GROUT 40 can be used in machinery bases, structural columns, pumps and accessory bases, anchor bolts, bearing plates, floor grids, crane tracks etc.
  • CERA GROUT 40 is an excellent material for structural concrete repairs.

Recommended Method Of Application:
  • Surface Preparation: All areas to be grouted shall be clean and free of laitance, grease, dirt and contaminants. All loose material shall be removed. In case of repair, the concrete must be hacked back until a sound surface is obtained. All metal components shall be de-rusted and made free of paints or oils.
  • The prepared concrete surface should be saturated before application, with clean water. Remove excess water from voids and holes prior to grouting.

Form Work:
  • For machine and column bases, firm form work should be provided which will allow for rapid and continuous placement of the grout and complete filling of space to be grouted.
  • Support elements should be anchored so that no movement is possible. Removal of formwork should be done only after CERA GROUT 40 has hardened properly.

Mixing:
  • The dry grout should be mixed with recommended amount of water - typically 13.5% -14.5% by weight of grout that is approximately 3.0 – 3.6 liters per bag of 25kgs. The grout shall be added to the water in a container. Quantities which can be placed in about 15-20 minutes only should be mixed at a time. Use mechanical mixer to obtain a consistent mix.
  • Please note: The grout may appear stiff initially, however do not add additional water as it would have a negative influence on the properties mentioned in the catalog. On thorough mixing of the mix for about 10 minutes high workable mix with self- compacting property is obtained.
