Do not forget to make upper (external) surface of the unit has to aligned with wearing surface make equal to passageway from its wearing.

Therefore, its very important to set the units to levels of wearing vigilantly and precisely.

13- Firm With Bolts and Washer

Subsequently fix special designed washer and screw with examined road level and aligned level during the design of joint rainbow transflex, ensure that the wearing surface is as consistent and smooth as possible from either sides of the joint.

The surface should be properly laid.

11

14- Masking Tape

As followed by step 13 (firming with bolts and washer).

It is a process of using Mask tape for safety of studs, washers as well as for concrete and for dust. This step is useful for step 17 which is curing process.

15- Cutting of final Asphalt

After the satisfaction of fixing, alignment and adjustment of male female. The second step is cutting of asphalt for concrete.

12

16- Concrete on both sides of Masking tape

Chipping, removing dust and cleaning each surface, use chemicals on old and new concrete to make auxiliary intensity/strength, and also use special chemical for concrete to make premium strength.

17- Curing for concrete strength

As followed by previous action, this process is for curing of concrete to make optimum dilution.

Curing process is minimum seven (7) days.

13

18. Cleaning holes through high compressor

Using high air compressor to cleaning the dust and expansion joints. This procedure will help and make easy for next phase.

19- Filling Holes and Gaps

This process is for filling holes with chemicals, make sure of examined gaps and other final finishing procedure.

14

Mixing Polysulphide Sealant for holes and gaps, for the long lasting of bolts, washer and studs.

Critical to successful concrete repair is proper surface preparation of the area being repaired. This includes complete removal of concrete around and below the reinforcing steel and preparation of the substrate. Combined, these techniques ensure maximum bond between the new repair material and the existing substrate, resulting in effective, long-lasting repairs.

An effective repair strategy must draw from a variety of repair materials, each having an installation technique that best suits both the material and the strategy.

At Structural Preservation Systems, we have the expertise to utilize specialized techniques applicable to surface repair material installation.

CONCRETE REPAIR:

Concrete repair replaces defective, damaged, or deteriorated concrete; restores structural function; protects the surface or underlying concrete from aggressive environments; and restores any lost performance requirements.

Concrete repair problems are diverse in nature. Each condition requires a clear understanding of what is expected of the repair including appearance, protection needs, and load carrying requirements.

Expansion Joint Fixing

Whether you're fixing of expansion joint material, the application method for repair is always the same. Expansion joints are an integral part of concrete structures. They are built into deck systems to control the stresses of volume changes in concrete. Depending on the type of construction (cast-in-place, precast, etc.), joints are installed to isolate ramps, buildings, and large expanses of deck surface. They may also be needed to provide free rotation of deflecting members. Most joints open and close according to daily and seasonal fluctuations in deck surface temperatures.

Joints provide a natural place for water, salts, and debris to collect. They also present a hazard to pedestrians who may trip over them. To prevent these problems, joint seals can be installed. Seals must be designed for the intended movement of the joint, as well as for water tightness, wheel action (traffic, equipment), pedestrian safety, and reparability.

The light emitting paint is nonconventional source of energy. The light emission is guaranteed lifelong. These paint may be termed as illumination source with least installation cost, no operating cost & maintenance free. It is absolutely safe, nonradioactive & nontoxic.

Road Safety Paints:

SERVICES:

Other than Paints, Inks, Vinyls & Color Transfers we also undertake job work of road marking, lane marking & zone marking for indoor & outdoor areas. We also offer signage & hoardings as per customer's specification. We have our infrastructure with digital cutters, fabrication & paint shop.

Light Emitting Paint for Road

We offer light emitting paint for road. There is great scope for this paint in infrastructure projects like road, highways, express highways, bridges, tunnels, etc. Quiet high number of accidents takes place due to poor lighting. The present hot melt plastics & fluorescent paints used for lane marking and road marking are visible only when light fall on it in a particular angle. Whereas light emitting paints offer great visibility in the dark. It avoids many of mishaps and accidents. Also the the fluorescent paint looses its luster within short period.

On the contrary light emitting paints offers illumination for long period. The lane marking strips, zebra crossings, direction indicator arrows, STOP signs at signal are being painted with light emitting paints. The anti crash barriers installed at sides of the highways are painted with black & white strips of light emitting paints, adding safety in the dark too. Various curves & obstacle at ghat sections & hilly terrains can be easily indicated in dark with light emitting paints. All these infrastructure projects spend huge expenditure on street lighting for installation, maintenance & operating cost. Light emitting paints is maintenance free solution with no operating cost & minimum expense on installation. Street lights operated by photoelectric switches often malfunction in urban areas causing collision of vehicles against dividers, side railing, pillars & post.
