POLYGROUT U.W

  High strength for maximum load bearing.

Non - shrink with minimum positive expansion for high tolerance performance.
Low porosity with better resistance to sea water attack for embedded reinforced steel. Non wash characteristics to retain grout properties.
Non wash characteristics to retain grout properties.
Highly fluid and extremely peaceable for easy water displacement.
Chlorides free which may contribute if any to corrosion of base structure.

Guide for Applications
 
Preparation Careful preparation is a must for a successful grouting operation.
Concrete surfaces to be grouted should be clean and free from rust, grease, oil , this could be done by sand blasting or high pressure water jet.
Scrabbling or brush hammering may be used in non immersed or intermittently immersed substrates.
Prepare properly strengthened shutters that are completely impervious to retain the flowing Grout.
 
Mixing
 
Use approximately 4.5 lit. of potable water to 25 kg bag. to reach a fluid consistency.
Do not add sand or cement to the grout since this action will change its characteristics. When filling large volumes, it is advisable to fill out POLYGROUT S.W with well graded silt free aggregates.
First add the required quantity of water as the mixer operates.
Mix for 5 minutes, then place the grout.
For small quantities use paddle mixing drill. For large quantities use paddle type mortar mixer.
Hand mixing is not recommended.
Do not mix any more grout at one. time than can be placed in 20min.
Pass the mixed grout through requirements a 5 m.m. sieve to remove any lumps prior to placing
 
It is very important to gauge accurately the right amount of water & the mixing time
Placing
Continuous pump POLYGROUT S.W.
through a flexible pipe of a minimum diameter of half an inch.
The bottom of the tube should be placed in lowest point in the form, it may be raised if necessary to reduce any back pressure. 
The bottom of the tube should never be raised above the level of the grout.
Place the grout within 20 min.
and restrict the grout flow at the start of the operation in order to avoid any water entrapment.
POLYGROUT S.W. may be pumped in thickness up to 20 cm when placed under water.
For thicker sections to be placed, under water, over 20 cm, it is necessary to fill out POLYGROUT S.W with rounded well graded aggregate, in the size rang 2mm.up to 8mm.
with the ratio of 1 : 1 by weight Unrestrained areas should be kept to a minimum.
 
Yield
 
The approximate yield per 25 kg. bag will reach 14.5 liters.
The approximate yield per 25 kg. bag will reach 14.5 liters
 
Packaging
 
POLYGROUT S.W. is supplied in 25 kg. bags.

Curing
 
Curing is not required when grouting under water.
 
Shelf Life
One year when stored as recommended.
 
Storage
 
POLYGROUT S.W. should be stored in non humid shaded areas.
 
Cleaning
Use hot water for cleaning equipments .
 
Health And Safety .
