Injection Resins

INJECTION RESINS WITH
EFFECTIVE SOLUTIONS IN WATERPROOFING AND STRUCTURAL STRENGTHENING!

Injection Resins

Injection resins are special chemical systems that are applied by injecting under pressure into structural defects such as cracks, gaps or joints and that cure in the application area to form a water-impermeable, filling or structural layer. In various structural elements such as concrete, stone, brick waterproofing, crack repair And structural reinforcement is used for the purpose of.

Polyurethane Based Injection Resins
These resins expand rapidly when in contact with water, forming a foam or elastic (rubbery) structure. They are generally preferred to stop active water leaks. They are offered in single-component or two-component formulations.

Advantages:
– It reacts with water and expands, filling the space completely.
– Creates a flexible and waterproof structure.
– Curing time is very short, application speed is high.

Epoxy Based Injection Resins
These systems used for dry cracks create a hard and rigid structure with high strength after curing. It is used to restore the original structural integrity of reinforced concrete elements.

Advantages:
– Provides high adhesion strength and ≥ 80 MPa compressive strength.
– Ideal for situations requiring structural reinforcement.
– Thanks to its low viscosity, it can penetrate even thin cracks such as 0.1 mm.

Things to Consider During Injection Application
– The type of crack must be analyzed correctly: is it active water ingress or dry structure?
– A pump selection appropriate to the viscosity of the material to be used should be made.
– Temperature and humidity in the application environment affect the curing time.
– Polyurethane resins expand as they come into contact with water; correct dosing is essential.
– In epoxy injections, the surface must be completely dry.

Application Areas
– Foundation curtain walls
– Parking lot insulation details
– Metro and tunnel projects
– Dam and pond concretes
– Water tank inner surfaces
– Column, beam and floor cracks
– Elevator shafts and shafts
– Water sealing systems between joints

Sempoly Construction Chemicals As, we offer a wide range of reliable, long-lasting and high-performance product solutions that the construction sector needs. The product groups we develop are complementary to both surface preparation and coating and insulation systems. Each of our systems formulated in accordance with international quality standards; provides maximum performance in many application areas such as floor covering, waterproofing, repair and maintenance.

Linings:
Our polyurethane and epoxy based primers, developed to establish a strong bond between the surface and the coating, increase adhesion strength and ensure system integrity. With advantages such as high moisture tolerance, chemical resistance and fast curing, alternatives suitable for every surface type are offered.

Epoxy Floor Coatings:
Epoxy floor coatings, which are a perfect solution for industrial and commercial areas, stand out in terms of chemical resistance, abrasion resistance and hygiene requirements. They offer special floor solutions for each project with different thickness and color options.

Polyurethane Liquid Membranes:
Polyurethane liquid membranes, which offer jointless and seamless solutions in waterproofing, have crack-bridging properties thanks to their elastic structure. They provide long-lasting waterproofing in interior and exterior spaces with their aliphatic and aromatic options.

Polyurea Coatings:
Our polyurea systems, applied with hot spray technology and cured within seconds, show superior resistance to heavy traffic loads, chemicals and UV rays. It is used safely in terraces, parking lots, industrial floors and infrastructure projects.

Injection Resins:
Polyurethane and epoxy based injection systems offer effective solutions for repairing concrete cracks, stopping water leaks and ensuring structural integrity. They provide successful results even under difficult conditions with their low viscosity and high expansion types.

Repair Mortars and Complementary Materials:
Epoxy grouts, joint fillers, surface adhesives and system additives developed for the protection and repair of building systems support the application process. They provide permanent performance by working in full harmony with the system.
