FAQS
Have Questions
We’ve heard it all. Here’s everything you need to know before working with us.
Injectable waterproofing can be used on structures at any stage of construction, though it’s most commonly applied to existing buildings as a remedial solution. It’s often recommended for structures showing signs of water damage or leaks, such as wall cracks, construction joints, or pipe penetrations.
For existing structures, the process can be more complex, as Stop and Seal may need to remove materials or make modifications to inject the waterproofing into areas like basement walls, floor slabs, or lift pits.
