PRATECH® RP88T
Structural Filler Repair Mortar

It is a specialized repair material used to repair, reinforce, and restore the structural integrity of cracks, holes, or damage occurring on concrete or other structural surfaces. It is cement-based and possesses thixotropic, high-strength, and high-performance properties thanks to its special additives.

  • Its thixotropic nature prevents sagging in overhead applications.
  • It has high adhesive strength.
  • Can be applied in a single layer at thicknesses between 5–40 mm.
  • Offers high resistance to water and chemicals.

ADVANTAGES

High Durability: The structural repair filler mortar possesses high durability properties.
Flexibility: Some structural repair filler mortars have flexibility properties, providing resistance against structural movements and crack formation.
Waterproofing: Once hardened, it can form a water-impermeable layer, enhancing its resistance to environmental factors.
Excellent Adhesion: It adheres well to the surface, which increases the durability of the repaired area.
Workability: It exhibits good workability, facilitating ease of application.

APPLICATION AREAS

• For the repair of all types of reinforced concrete structures.
• For the repair of reinforced concrete surfaces located underground and underwater.
• For chamfering and surface smoothing before waterproofing applications.
• Used for the repair and leveling of high-strength concrete elements.

SURFACE PREPARATION

Cleaning: The surface must be free from dust, dirt, oil, and other contaminants. All contaminants on the surface should be removed using compressed air, a brush, a broom, or suitable cleaning materials.
Surface Smoothing: If the surface is rough or uneven, a correction and smoothing process should be performed. This step ensures that the repair mortar adheres properly.
Moisture Control: The moisture content of the surface must be checked. Generally, the surface should be below a certain moisture level before applying the repair mortar. Excessive moisture can affect the mortar’s adhesion properties.
Primer Application: In cases where the surface is absorbent, a primer should be applied. The primer ensures better adhesion of the mortar to the surface and helps achieve a homogeneous finish.
Surface Must Not Be Wet: Care must be taken to ensure that the surface is not wet before applying the repair mortar. Wet surfaces can negatively affect the mortar’s ability to adhere.

APPLICATION TYPE

• Slowly pour 25 KG powder mixture over 3.5–4.5 liters of water and mix for 3–5 minutes until a homogeneous consistency is achieved.
• The mixture should be stirred slowly using a low-speed mixer (less than 500 rpm).
• After a 3-minute resting period, mix the mortar again at low speed for 1–2 minutes before application.
• The rested and ready-to-use mortar should be applied to the surface using a steel trowel.

UYARILAR

Protect your skin, eyes and respiratory system when working with mortar. When mixing mortar, use a low speed mixer to minimize dust formation. When preparing mortar indoors, ensure adequate ventilation or use a respiratory mask. Use clean and dry containers for mixing the mortar. Do not add any foreign matter to the mortar. Do not apply mortar in extremely hot or cold weather.
