Repair Mortars and Grouts

  TDS Technical Document Sheet   

Product Description
it is a cement based, one component, non-shrink, flowable repair and bedding mortar with very high
strength and especially developed tor wind turbines.

Areas of Usage
• it is used in fixing wind turbines,
• in machine rails and foundations
• in cold conditions and cold storehouses
• in repairing concrete floors which are exposed to vehicle and pedestrian traffic

Features and Benefits
• it gains strength even at temperatures under zero. Min. +5 °C
• it is easy to apply since it has flowable property.
• it has broad application areas since it does not shrink
• No decomposition and water formation
• Perfect adhesion and strength
• High application thickness as much as possible by adding aggregate with proper size
• High stiffness and high abrasion resistance
• it works with the old concrete as monolithic since it has high adherence
• Application thickness can be between 1 O mm and 150 mm
• it has high protection of reinforcement and carbonation resistance
• it has freeze-thaw resistance.

Application lnstructions
Surface Preparation: The surfaces must be clean, smooth, solid, free from any antiadhesive
substance such as dust, oil, dirt, rust, mold oil, detergent and waste. The repairing corners should
be cut vertically with 1 O mm deepness. The reinforcements should be changed with the new ones
because of structural reasons if they have serious damageor the cross sections are below the
necessary safety limit. When auxiliary reinforcement is applied, the thickness of the reinforcement
should be 2 cm minimum. The surface ice should be melted completely before TEKNOGROUT
REPAIR is applied. Even if TEKNOGROUT REPAIR is applicable at low temperatures as +5°C,
the surface temperature should be higher than +5°C and lower than +35°C. Absorbent
surfaces should be wetted in advance but there should not be any remaining water drops.
Mixing: 2.5-3.5 it clean, clear water is added into a clean container which is free from all kinds of
materials that prevent adhesion. 25 kg TEKNOGROUT REPAIR is poured into the container filled
with water. The product is mixed with a low speed mixer until a homogeneous mixture without
lumps is obtained. The mixing time should be 3 minutes minimum. The mortar obtained at the
end of this process should be placed immediately. After the reaction of the material complete, it
should not be mixed again with water.
The mixture should be placed in 2.5 min. depending on the temperature and the amount of water.
TEKNOGROUT REPAIR should be poured from one side to fiil the gaps surrounded on four sides
and covered. So it discharges air and prevents gaps. it can be pushed from one side with a long
piece of iron during casting to speed up the flow.
The thickness of the casting should be between 1 O mm and 150 mm layer thickness at a time. it is
recommended to carry out a preliminary test if small diameters anchors will be used.
For applications thicker than 150 mm, it is possible to add aggregates with the diameter of 5 - 12
mm at a rate of 30 % of the material. Aggregate addition can be done by two ways;
• The aggregate is added into prepared mortar. The addition continues until a homogeneous
mixture is obtained.
• Aggregate is poured or spread on the application floor. Then, the prepared TEKNOGROUT
REPAIR mixture is poured onto it. The self-leveling mortar surrounds all around the aggregate
and a high strength cement is obtained.

Application Notes / Restrictions
• The reaction times of cement based products are affected by the air and surface temperatures.
The reaction times decrease in warm conditions and increase in cold conditions.
• Hot water should be used in cold conditions.
• Cold water should be used in warm conditions.
• During the application of the product, work clothes suitable for occupational health and safety
rules should be worn and appropriate glasses and masks should be used.
• The prepared mixture should be placed in 5 min. depending on the temperature and the amount
of water.
• Do not apply at temperatures below +5 °C and above +35 °C.
• Do not apply TEKNOGROUT REPAIR if it is expected for the temperature to decrease below
+5 °C during the application or during 24 hours after the application.
• After the application, it must be protected from the bad weather conditions such as direct
sunlight, strong wind, high temperature (above +35 °C), rain and frost. The product should be
cleaned thoroughly with water and detergent before it is fully cured and hardened.
• After the application, the equipment should be cleaned immediately with water before the
product is hardened. lf the product is hardened, the equipment should be cleaned by
mechanical methods.
