BASEMENT RAFT AND RETAINING WALLS

TREATMENT TO RAFT SLAB:
Providing and applying Vandex Super cementitious based crystalline, in depth concrete waterproofing to Raft by dry sprinkling Vandex Super immediately prior to casting of Raft concrete. All construction joints and cold joints shall be treated with Vandex Slurry poured on to old concrete immediately prior to casting of new concrete. Upon sprinkling of the Vandex waterproofing material, it shall react with the free lime and moisture within the capillary tracts of the concrete, to form insoluble gel crystals that penetrate deep into the concrete. These insoluble crystals formed shall permanently block the capillaries and minor cracks up to 0.3mm width that are present in the concrete, and driving out water to provide a permanently waterproofed concrete. The compound of active chemicals, while in the absence of moisture shall remain dormant and re-activate once the concrete structure is re-exposed to moisture or water.

The Vandex cementitious waterproofing treatment shall remain waterproofed even under pressure up to 12 atmosphere (120.00 meters) (tested in accordance to DIN 1048), and at the same time allow the concrete to “breathe” by allowing the passage of water vapor out of the structure.

TREATMENT TO CONCRETE DEFECTS LIKE CONSTRUCTION JOINTS COLD JOINTS, HONEY COMBS & POROUS CONCRETE:
All construction joints, honey combs, cold joints, after casting shall be treated by hacking open the affected area to sound concrete, fixing nozzles and grouting the same, under pressure with cement slurry mixed with plasticizer, and non shrink additive.

 REATMENT TO RETAINING WALLS:
Cleaning the entire surface by water jetting, wire brushing and repairing the construction joints, honey combs etc. Pre-wetting the surface and applying Vandex Super slurry in two coats. Upon application of the Vandex waterproofing material, it shall react with the free lime and moisture within the capillary tracts of the concrete, to form insoluble gel crystals that penetrate deep into the concrete. These insoluble crystals formed shall block the capillaries and minor cracks up to 0.3mm width that are present in the concrete, and driving out water to provide a permanently waterproofed concrete. The compound of active chemicals, while in the absence of moisture shall remain dormant and re-activate once the concrete structure is re-exposed to moisture or water he Vandex cementitious waterproofing treatment shall remain waterproofed even under pressure up to 12 atmosphere (120.00 meters) (tested in accordance to DIN 1048), and at the same time allow the concrete to “breathe” by allowing the passage of water vapor out of the structure. Cost to include base preparation including cleaning and wire-brushing the surface. Treatment to honey combs, joints, upturns etc. to be measured separately.

 Vandex BB 75

WATER TANKS

TREATMENT TO CONCRETE DEFECTS LIKE CONSTRUCTION JOINTS COLD JOINTS, HONEY COMBS & POROUS CONCRETE:
All construction joints, honey combs, cold joints, after casting shall be treated by hacking open the affected area to sound concrete, fixing nozzles and grouting the same, under pressure with cement slurry mixed with plasticizer, and non shrink additive.

TREATMENT TO FLOOR AND RETAINING WALLS OF TANKS:
The Vandex BB 75 shall consist of rapid-hardening portland cement, specially treated and graded grain-size distribution, and special chemical ingredients of an inorganic nature. The Vandex BB 75 cementitious waterproofing membrane shall remain waterproofed even under pressure and tested to 7.0 bar, and at the same time allow the concrete to “breathe” by allowing the passage of water vapour through the structure. In addition, the Vandex cementitious waterproofing material shall protect the concrete against ground water, aggressive ground water and certain chemical solutions. Cleaning the entire surface by water jetting, wire brushing, etc. Pre-wetting the surface and applying VANDEX BB 75 slurry in two coats with trowel.
