Polyurethane Injection grouting is a way that will involve the injection of expanding polyurethane to chop-off water move by means of concrete joints or cracks or to fill voids beneath slabs or powering concrete partitions.
PU grouting presents numerous Rewards above classic waterproofing techniques prevalent Utilized in Singapore, which includes:
As one of several main waterproofing contractors in Singapore, we recognize these challenges and offer an extensive array of solutions to make sure the longevity and toughness of your residence.

The desire residences need not be huge or have a lot of facilities. Maintaining this type of splendid property is essential as it can help safeguard the structural foundation and maintain its aesthetic worth.
Our variety of Injection Grouting Solutions is ideal for filling up the cracks in buildings and bonding concrete and also other components completely. We use modern day procedures and machines for producing our injection grouting solutions.
Furthermore, the area point out of polyurethane foam components affects water absorption. Chen et al. [89] investigated the effect in the surface area point out of polyurethane foam on their water absorption level. The effects confirmed the water absorption from the uncoated sample was 2.2%, though the water absorption of the coated sample was 0.one%. They noticed which the water absorption charge was very low once the metallic movie was coated within the surface area of your foam product because the metallic material experienced an exceedingly very low water permeability, and it acted as a barrier layer towards the foam. Also, the dampness absorption rate of polyurethane modifications having a adjust during the pore dimensions and specific surface area place [90].
PU grouting is an excellent selection for filling cracks in concrete surfaces just before making use of waterproofing product or coatings. It's also beneficial in wall design where it fills the Area among two concrete slabs, providing an airtight water barrier.
The 1-ingredient open up celled foams within the competition are regarded as momentary water stoppers which need a second injection using a shut mobile versatile two-element resin to get Long lasting and durable waterproofing.
PU grouting is mainly employed to restore cracks and repair service water damages that were performed to partitions, flooring, etcetera. It prevents cracks from leaking continuously and it's employed to keep up the construction’s operational integrity.
Municipalities are routinely trying to get helpful repair solutions to simplicity the load on their water therapy crops by lessen groundwater infiltration.
Varieties of PU grouting technique are lower-strain injection and significant-strain injection. The usefulness of polyurethane foam injection lets liquid polymer to inject into the crack.
In down below grade buildings, This is often a good way to fill voids Which might be current outside the house the composition. After the leak is lessened into a workable degree, hydrophilic resin website ought to be injected in the defect to back up the hydrophobic content.
This is among the oldest waterproofing methods to choose from, and it’s well-known for a reason. Injection grouting yields good final results, specially when you work with experts like those We've got on our workforce.
