Mapei’s Arsenal of Products Finds Increasing Use in Significant Projects

230

Over the past few years, Mapei’s diverse range of products has been finding increasing roles in a diverse range of projects across India. Mapei products have and are being used in infrastructure projects, religious projects, residential and commercial buildings, and monuments, to name a few. In this article, we explore the various Map products used in the construction of the World’s tallest statue, the Statue of Unity.

Statue of Unity

The statue, which stands at 182 m high, is the tallest statue of the world. It pays homage to India’s most celebrated statesman and freedom fighter Sardar Vallabhbhai Patel. The monument is an engineering marvel and is strategically designed to counter the forces of nature, whilst enduring through time. It encloses a few museums, viewing galleries, an exhibition hall and more. Mapei supplied several products for its construction, these include: waterproofing materials (IDROSTOP, IDROSTOP MASTIC, PLANISEAL 88), wall coatings (ANTIPLUVIOL S), products for concrete repair (MAPEGROUT EASYFLOW), soundproofing materials (MAPESONIC CR), adhesives for ceramic tiles (KERAFLEX MAXI S1, KERALASTIC) and resilience enhancing materials (ULTRABOND ECO V4 SP), as well as admixtures for concrete (DYNAMON SX). Below showcases why these products were chosen.

Concrete Admixtures

Dynamon SX (high PC) range of products was used for a self compacting concrete of grade M50 and M65. This product enhanced the concrete’s properties (flow and compaction) at low W/C making it pump-able up to a height of 182m.
Dynamon SX range of products is a modified acrylic super-plasticiser for concrete, characterised by its low water/ cement ratio, very high mechanical strength and long workability times.
Concrete manufactured with Dynamon SX range have a high level of workability (consistency class S4 or S5, according to EN 206-1), and are consequently easy to apply when fresh. At the same time, they offer excellent mechanical performance when hardened. Dynamon SX range is especially suitable for all applications where there is the need for greater water reduction, along with relatively high mechanical strength at the early stages. Its performance makes it particularly suitable for manufacturing self-compacting concretes since Dynamon SX range can ensure high workability.

Waterproofing
IDROSTOP

IDROSTOP is a hydrophilic expandable pre-formed flexible rubber stop for watertight construction. Idrostop is used to produce watertight construction joints in civil, industrial and hydraulic construction. Construction joints created with Idrostop are watertight upto 5atm of pressure. Unlike materials made of alternate composition that lose efficiency in repeated wet/dry cycling, Idrostops unique composition allows it to maintain performance even in aggressive environments.

Uses

  • To waterproof joints between concrete foundations and walls
  • For waterproofing contact joints between different building materials, such as steel and concrete, or stone and concrete
  • For waterproofing contact joints between different types of materials, such as PVC or steel tubing penetrations in concrete swimming pools, sewage treatment tanks, reservoirs, and hydraulic projects in general
  • For waterproofing cold joints (temporary shrinkage joints) created during pouring to reduce the risk of cracking in long and monolithic structures
  • For waterproofing construction joints where, conventional water-stops cannot be installed easily and securely because of highly congested reinforcing bar
  • For waterproofing construction joints in tunnels, dams and hydraulic projects including potable water reservoirs.

Idrostop Mastic

Idrostop Mastic is a one-component thixotropic adhesive made from sililated polymers characterised by its high initial tack and rapid final hardening. It contains no solvents and does not give off unpleasant odours. It also has very low emission of volatile organic compounds and is certified EC1 R Plus by the GEV Institute.
Idrostop Mastic used for

  • Bonding Idrostop to concrete between foundation slabs and vertical walls before carrying out second pours.
  • Bonding Idrostop around PVC and steel pipes before pouring concrete.

Planiseal 88

Planiseal 88 is a one component, polymer modified cementitious coating for waterproofing concete and masonry surfaces.
Planiseal 88 is used for

  • For Waterproofing horizontal, vertical and overhead surfaces
  • For interior or exterior concrete applications such as walls, retaining walls, wet rooms, pools, planters, irrigation canals, culverts, concrete jersey, barriers, beams, columns, building facades, overpasses and piers exposed to positive or negative hydrostatic pressure.

Wall Coatings
Antipluviol S

Antipluviol S is a Silane and siloxane based transparent water-repellent impregnating finish in solvent solution. A colourless protection against rain for exposed concrete structures, cement renders, cellular cement, facebricks, exposed concrete blocks, natural and artificial stone, non-glazed ceramic tiles, etc.

Antipluviol S is used for

  • Repair of plastered walls exposed to rain.
  • Preventive treatment of exposed concrete against carbonation.
  • Colourless water-repellent protection of historic buildings or those of special architectural value.
  • Water-repellent treatment of walls and facebricks

Concrete Repair
Mapegrout Easyflow

Mapegrout Easyflow IN is a one-component pre-blended packed thixotropic cement based concrete composed of hydraulic binders, synthetic polyacrylonitrile fibres, organic corrosion inhibitors, special water-retaining, expansive admixtures and selected aggregates. Repair of deteriorated concrete structures by using a spray rendering machine. The product is especially suitable when easy pumping is required even over long distances and under constant high heads. Mapegrout Easy Flow IN can be applied for:

  • Repair of highway viaduct pillars by using a spray rendering machine.
  • Repair of hydraulic works such as canals, dams, spillways, basins, etc.
  • Repair of road and railway tunnels.
  • Repair of precast concrete structures.
  • Repair of concrete structures damaged by corroded reinforcing bars.

Soundproofing
Mapesonic CR

Mapesonic CR is a thin section soundproofing membrane to combat the noise of footsteps transmitted through floor slabs, applied before laying ceramic, stone, resilient and multi-layered parquet floors.
Mapesonic CR can be used as

  • Under-floor soundproofing system applied in a thin layer to counteract the transmission of noise through floors caused by footsteps.
  • Mapesonic CR has been specifically developed for application in existing buildings to improve soundproofing without removing the floors and screeds.
  • It is particularly suitable, therefore, for all buildings (residential units, hotels, offices, rest-homes, schools, etc.) under renovation.
    Some application examples of Mapesonic CR
  • under resilient floor coverings (PVC, rubber, linoleum);
  • under multi-layered parquet;
  • on cement-based substrates;
  • on old ceramic and stone floors.
    In Statue of Unity project, Mapesonic CR was used in the walk area where soundproof was required.
