Video Description

Product Overview

It is a polymer chemical grouting plugging material produced by MDI chemical reaction of polyisocyanate and polyalkyl polyether. It is used to repair concrete cracks in buildings, and to strengthen the foundation. It is suitable for the crack stop and reinforcement of underground engineering such as subway, tunnel, culvert, dam, port pier, garage and civil air defense.

Performance Characteristics

Good water transport, after the water will immediately chemical reaction foam expansion, and consolidated with sand and gravel soil into a hard substance to block cracks, permanent water stop.
The gel time can be controlled, the foaming time can be controlled within ten seconds to ten minutes according to the water temperature and water quantity, and a small amount of catalyst can be added if necessary.
Large expansion, no shrinkage, strong adhesion with the base, strong adaptability to water quality, sea water can also be solidified.
Single liquid grouting, low viscosity, good irrigability, simple construction, easy cleaning.

Wear protective products such as goggles and gloves during construction

Storage and transportation

During transportation, the product should be strictly protected from rain and sun, avoid collision and fall during handling, and replace the original packaging with a new drum in time.
The product should be sealed and stored in a dry and ventilated place indoors, away from open flame, isolated from heat source radiation, shelf life of 6 months under the original packaging.
Special iron drum, weighing 10kg/drum,

Structural Cracks And Seepage

① Drill holes at an angle of 45 degrees to the left or right 2-5 cm from the lower part of the crack to the depth of half the thickness of the structure. Drill holes in sequence from low to high, with an appropriate hole spac- ing of 20-30 cm. After drilling to a high place, bury the water stop needle.Since the cracks in the general structure are irregular, special attention should be paid to the fact that the grouting needs to cross the crack surface when drilling, and the grouting will be effective.

② After the grouting water stop needle is placed, it is poured with chemical grouting material until the grout seeps out of the surface of the structure.

③ 48 hours after the grouting is completed, the grout- ing water stop needle can be removed.

Honeycomb Leaking

① At the range of the honeycomb, drill a hole every25-30 cm, the depth is generally suitable for the thickness of the structure, and then place the grouting water stop needle and rotate it to fix it.

② After the water-stop needle is placed, inject the chemical grouting material with a high-pressure grouting machine until it is found that the grouting material seeps out of the surface of the structure.

③ 48 hours after the grouting is completed, the grout. ing water stop needle can be removed.
