Description of Product
PoliGrout®35-GS, is a cement based, single component, high strength Grout Mortar. Especially for aboveground steel wind turbines, It is designed for structural filling of joints and grouting under the base plates.

Fields of Application
- Wind turbine foundations
-Construction of shear wall caps and column caps, 
-Fixing of pre-cast concrete elements, 
-Fixing of the turbines on the foundations, 
-Fixing of the generators, compressors and pumps on the foundations, 
-Fixing of the industrial machines on the foundations, 
-Fixing of the steel columns on the RC foundations, 
-Filling of the voids in the jacketing applications.

Features and Benefits
-Mixed with only water and can be applied easily. 
-High compressive strength. 
-High fluid consistency. 
-Free of bleeding.
-Resistant to water and weather conditions. 
-Perfect bonding to the concrete and steel. 
-Non-shrink.

Application Procedure
Preparation of Substrate
The concrete should be free of frost, curing membranes, waterproofing treatments, oil stains, laitance, friable material and dust. 

The concrete surfaces should be chipped and if there is a water leakage it must be drained or properly plugged. Base plate, rods and bolts should be free of oil stains, grease and dust. Enough number of holes should be opened on the base plate for air drain. Machine should be assembled and balanced before grouting. The concrete surfaces should be saturated with water at least 6 hours before the grouting.

Formwork Preparation
The form material should be waterproof and resistant to hydrostatic forces of the grout. Formwork installation should be done against the possible leakage of the cement paste. An opening should be designed in the formwork with a width of 5 cm at minimum for pouring the grout. For providing a constant pressure for easy compacting of the grout the forms should be as high as possible in the pouring side. In grouting of huge base plates, special pipe and pump  systems can be used or grout can be prepared with 5% extra water. For preventing the pressure releases, the forms should be placed without any tolerances and gaps between the concrete and form material.

Mixing
Add enough water into a clean mixing bucket by using a proper water gauge. Add the powder into  the  bucket  slowly and  continously. Mix the fresh mortar with a proper electrical mixer (300-600 rpm) for 4  minutes until having a 
Homogenous consistency. Let the mortar have rest for 4 minutes and re-mix for 30 seconds.

Application Method
In the case of operating neigbour machines, a glass of water should be put on the grouting base and the vibrations caused by the environment can be observed. If  needed, surrounding machines should  be swicthed  off until  (10-12  hours in 20˚C) the grout sets. PoliGrout®35-GS should be poured directly  into the formwork or it should be pumped under pressure. Application thickness should be 1-4 cm. For preventing the possible air gaps in the formwork, pour the grout from single opening and let the air draining.  Use a steel hook for placing the grout under the plates and do not use vibrator. For thicker applications second layer of the mortar should be applied  in same way or consult to the POLİKROM Yapı Kimyasalları Technical Service.

COVERAGE
19.00 kg/m2 for obtaining 1 mm thick layer.

Watch Points
-During the application the substrate and ambient temperature should be between 5-30˚C. 
-Open areas should be protected from the rain, wind, etc. aggressive whether conditions during the first 24-48 hours after finishing repair.
-Cement based materials’ pot life and curing times vary depending on the relative humidity, substrate and ambient temperature. Reaction gets slow in low temperatures and it causes to extension on pot life and working time. On the other hand high temperatures speed up the reaction, which results to short pot life and working time. For full curing  of material, both the substrate and ambient temperature shouldn’t be under allowed application temperature. 
-Do  not  use  PoliGrout®35-GS in  case  of contacting to liquids with a PH under 5.5. 
-Do not use vibrator for placing the mortar. 
-In low temperatures (5˚C-10˚C) the following precautions should be taken;   
The product should be stored in warm    conditions,   
Hot water (30˚C-50˚C)  should be used for    mixing,   Grouting area should be heated and    protected from cold. 
-In high temperatures (25˚C-30˚C) the following precautions should be taken;
The product should be stored in cool    conditions, 
Cold water (0˚C-10˚C) and ice should be    used for mixing,

CLEANING OF TOOLS
After the application all tools should be cleaned with water. PoliGrout®35-GS can be cleaned with only mechanical abrasion after hardening.

STORAGE
Store in original container in cool (+5˚C ± 25˚C) and dry indoor conditions.
SHELF LIFE 
6 months under proper storage conditions after production date.
