Frequently Asked Questions

How does chemical grouting prevent water infiltration?

Chemical grouting involves injecting specialized grout materials into cracks and leaks to seal and stabilize the surrounding area, effectively preventing water from infiltrating manholes.

Where can Chemical Injection be applied?

Soil stabilization with chemical grouting provides a permanent solution by creating a solid, water-resistant layer that reinforces soil structure. It’s perfect for adding stability around bridges, retaining walls, maholes, storm drains, and foundations, reducing erosion, and ensuring long-lasting support for construction projects, even in challenging conditions.
