Polyurethane injection can also be done at low pressure, exactly like an epoxy injection, or at high pressure (typically 1500 – 3200 psi). The high pressure injection of activated polyurethane uses an electric injection pump and packers hammered into drilled holes through the crack in a poured concrete foundation wall.
11/9/2020 · The Alchemy-Spetec Acrylate Gel Pump is a reciprocating positive displacement piston pump. The material is delivered at a mixing ratio of 1:1. The large and exact operating valves provide a high flow rate and high mixing accuracy. This pump is durable and easy to maintain.
1/12/2019 · 1. Initially, the observed water pressure loss is 84.9 %. When the pressure loss reduces to 49.43 %, water leakage also reduces in the waterproofed concrete. With the use of polyurethane resin injection in a concrete tank where the pressure is gradually incremented to 6 bar, only an 11.8 % pressure loss is observed. 2.
The mts PERFORATOR PGP 30/40 is a powerful gear pump for the injection of 2-component injection materials, mainly used for mining and civil engineering applications. It is meant for the use with common 2-component polyurethane injection materials with a mix ratio of 1:1
Whether you're dealing with a crack in your slab foundation, a sinking driveway, or a crack in a concrete wall, Ram Jack's polyurethane resin injection is a quick, affordable solution. Polyurethane resin injections are not only flexible in that they mold to fill the exact shape of the crack, but they also bond to almost any material.
Sika® Injection-201 CE is a very low viscosity, elastic and solvent free polyurethane injection resin. In contact with water, a uniform, closed and therefore watertight pore structure forms, which is elastic and flexible. Suitable for use in hot and tropical climatic

Polyurethane foam injection is ideal for filling wide cracks on concrete, masonry surfaces. The polyurethane foams can also be used to fill voids and sealing around pipes. Polyurethane foam injection is the ideal approach to stop your wall leakage.
4.4 Polyurethane (PU) injection Polyurethane grouts are usually used to repair cracks that are 0.12 mm and greater in width, both wet and active, and leaking a significant amount of water through joints or cracks. These grouts are semi flexible; thus, they may
Nextstar single component pumps are great for the busy contractor looking for a time-saving solution for small and hairline cracks to be injected with polyurethane. Nextstar dual component pumps are typically used with two component polyurethane or two component epoxy and can be a big timesaver for large projects versus using the cartridge system.
The process starts with ⅝" injection holes (size of a dime) strategically drilled to lift and restore sunken concrete. Polyurethane foam is injected into the holes causing a chemical reaction to fill uneven space under the slab. The holes are then patched with new
