PURINSEAL - Ground Stabilization
Polyurethane Injection resin systems have been developed for filling concrete voids and lifting collapsed concrete. Polyurethane injection is made for the purpose of correcting the concrete slabs of villa type buildings, concrete, asphalt, highway, stair concretes, field concretes, factory production areas and machine platforms. When PU is injected into the cavities of the lifting concretes, it applies a very high force to lift the field concretes or ground concretes, and ensures that it is fixed by lifting tons of load.
PU resin is injected into the soil cavities of concrete floors. After the gaps are filled, the air gaps in the foam act as hydraulic levers and are injected into the concrete until the desired level is reached, thanks to the injected foam.
Ground Stabilization Injections
Our products used in ground stabilization are as followed:
At this application, two component polyurethane injection products are preferred. One component products need water to react. One component products cannot be used as there is not water in every area where ground stabilization is conducted. Two component products fill in the voids in short time by quick reaction and ensure ground stabilization.
PURINSEAL EN 402: This two component low viscosity product is used to fill in the low volume voids or cracks. When contacts with water it forms little foam. It is applied with two component injection machine. However, according to the demands, it can also be applied with one component injection machines by expanding pot life.
PURINSEAL EN 403: This two component low viscosity product is used to fill high volume voids occur on the ground. When the two components are mixed, it forms foam by reacting without any need of water. Preferring this product in high volume voids provides a cost advantage. It is applied with two component injection machine.
