PU Grouting Injection

Reason for PU Injection

PU grouting is a specialized technique that involves the injection of expanding polyurethane to stop any water flowing down or through cracks or to fill voids under slabs, concrete joints or behind concrete walls and joints. It is a more popular choice compared to other waterproofing systems due to easy and fast installation and can be used for post construction applications. It also has long term durability and wear resistant, UV and weather resistant, alkaline, acid and fuels resistant.

The most common problems used this method are:

  • Deep holes in a wall, 
  • Cracks in concrete floors, 
  • Leakages flowing through cracks or even honeycombed concrete voids 
  • Water damages that can be seen in a wall that is damp.

Typically, PU injection may only engaging in those high rise building such as condominium and apartment. This is due to the maintenance process or repairing process that need to engage in high rise building are not easy.

How We Solve?

Polyurethane injection grout is designed to react with water and expand in place, forming a tight, impermeable, elastomeric seal that immediately stops the flow of the water. Polyurethane injection grout seals in 3 ways which first injection it forms a chemical bond to the concrete surface. Secondly it forms a mechanical anchor by entering the cracks and joints then thirdly it forms as seal by expanding within the cracks and joints. Inject some additional in the end process to tighten up the foam and guarantee a watertight seal.

We may go through 4 steps in order to fully complete our injection task. 

  1. First, our maintenance team may drilling a hole through the surface on a wall, floor or ceiling.
  2. After confirm the actual point of the cause, we will then inject the polyurethane grout.
  3. Then, the polyurethane grout will be expand and contact with the point of leakage. As the leakage may have water dripping through, the polyurethane will contact with water and crystalize through chemical reaction.
  4.  Then, the final steps will be cover up the whole and observe the outcomes of the performance.

Concrete Floor Repair

Concrete floor is mostly used due to its strong, hard and long lasting characteristics but over time, concrete floor damage can occur due to frequent temperature change, causing it to shrink and expand resulting in cracks. Using injection of resin such as epoxy and polyurethane crack filling compound is recommended as its characteristics is stronger than concrete and is compatible with floor coatings and paint. It is also designed to penetrate well into smallest cracks and long durability. However, is it best to contact a specialist to evaluate the concrete floor damage whether the floor can be repair or replace, measuring sizes of cracks to identify which fillers is most suitable and to check on floor moisture.
