2 BN Precast Pvt. Ltd has been conceived to usher in a new way of industrialized construction that provides precast elements for extremely durable, affordable, adaptable, livable and environmentally sustainable buildings that have high consistent quality and ensure high efficiency fast construction. Walltec Concrete Hollowcore Walls are the first phase of our plans and will provide a very efficient and economical way of building partition walls that surpasses current alternatives in every aspect. With our emphasis on quality we are looking at getting the best equipment and technology available on the market from an industry leader to manufacture our products. Our European made production line for lightweight precast hollowcore walls has a proven track-record over the last 20 years and is developed by one of the largest and oldest company for precast concrete elements and systems in the world. For our next phase we plan to introduce many more value added precast products and systems both structural as well as architectural, that provide an economical value addition. Vision To be a company that innovates, commercializes and adapts technologies to provide new ideas, products, and services to build and construct buildings and infrastructure - Better, Faster and more Economically than ever before. Values Truth, Integrity & Respect

3 Walltec Walls are non-load bearing concrete hollowcore walls that offer superior properties for a whole range of uses. The walls are produced to order in standard widths and thicknesses and in lengths to suit room height as well as desired densities and strength. Since their introduction in the early 1990s, Walltec walls have proven themselves in 13 countries with the strictest standards and requirements on seismic, moisture and fire resistance as well as sound insulation such as Germany, Finland, Ireland, Spain, Japan, Singapore, Malaysia and China. Walltec Concrete Hollowcore Walls are: mm long mm thick 600 mm wide as standard have 5-8 hollows depending on the thickness Conventional concrete 92mm thick wall having weight of around 110kg/m2 and lightweight concrete 92mm thick wall having weight of around 70kg/m2.

4 WALLTEC ADVANTAGES Economical Walltec walls offer lower initial as well as long-term costs when compared with other materials due to low product costs, elimination of plaster, no curing, no zariwork for conduiting, no lintels, no stone sills, no maintenance, no flaking/cracks, increased carpet area as well as flexibility to move partition walls when required. Lighter weight of the walls allows for lower deadweight thus reducing structural steel costs. Ease of Installation & Efficiency Walltec walls are factory made, transported to the site ready to install on pallets and manually erected on concrete floors. Highly versatile and fast to install, requiring just two regular construction workers to install up to 6 m 2 per hour and are precured thus do not require any curing. Can be cut, sawn and dimensioned as per requirement for installation at site. Projects utilizing Walltec walls can save weeks or months over other materials due to no prep work, fast installation, no curing time requirement and time saving with plumbing, electrical and HVAC conduiting. Aesthetically & Functionally Beneficial On account of their factory finish they are aesthetically pleasing. Due to its availability in different heights and thicknesses with no load-bearing application it provides total design flexibility. More carpet area due to lower thickness of 68mm to 140mm instead of brick partitions of 150mm with plaster on both sides. No lintels need to be cast as panels can be place horizontally as lintels where required. Due to its consistent line, length and levels Walltec walls do not require stone or wood sills/frames to level surfaces for windows and openings. Hanging wash-basins, cup-boards, mirrors, paintings with regular plug screws possible and can take as much as 350kg of load. Drilling, Nailing, Hammering as in any normal brick-plaster wall. Good workability, Less mess in installation, no curing, minimum waste at site and quick installation contribute to better site management. Low Maintenance No problems like leaching of salts from bricks over time. No cracking, flaking of plaster due to one homogeneous material. No plastering means additional saving on time, quality, maintenance etc. Superior strength & durability Strength gradually increases over time with an initial cube compressive strength of 25 to 40 N/mm 2 and an initial sectional compressive strength of 18 to 30 N/ mm 2. Walls do not deteriorate, experience creep and stress relaxation, lose strength and/or deflect over time.

5 Safety & Protection Provides excellent protection against impacts from intrusion, slamming, explosions, vehicles and projectiles. High fire ratings of upto 2 hours. Sound insulation of db Have passed tornado/hurricane/heavy rain-sleet-hail impact testing, giving owners an added level of safety assurance in areas prone to severe weather. Consistent Quality Because precast concrete products are typically produced in a controlled plant environment, they exhibit high quality and uniformity. Problems affecting quality typically found on a job site temperature, curing conditions, craftsmanship and material quality are nearly eliminated in a plant environment. Environment friendly No curing means massive water savings during construction. Lower raw material used than with other partitions and all raw material composed of natural materials that are nontoxic and environmentally safe. Given green building material status in Singapore, Malaysia and many other countries due to its very low energy used compared to other options. Weather and UV Resistance Walltec walls do not degrade from exposure to sunlight and provide excellent thermal shielding due to the hollows acting as heat sinks. Provides Thermal resistance of 0.4 (m2k)/w and better. Can use insulation between 2 walls for added thermal resistance mm Walltec Panels sandwich a 10mm thermocol sheet to provide a partition wall with excellent thermal resistance.
