Frequently Asked Questions
Which water-stop material is best for basements?
PVC and bentonite clay profiles are ideal for static basement walls, while hydrophilic rubber suits dynamic slabs.
Can you install water-stop in existing joints?
Yes—mechanical anchoring or injection methods allow retrofitting in active structures.
How do I choose between strip seals and compression seals?
Strip seals handle larger movements and traffic loads; compression seals are for smaller, static joint movements.
Are your resins suitable for wet conditions?
Our fast-reacting polyurethane resins bond in damp or submerged conditions.
Do you perform hydrostatic testing?
Yes—on-site leak tests validate installation integrity under real pressure.
What’s the lead time?
Standard profiles: 1–2 weeks; custom solutions: 4–6 weeks.
Can you train our crew?
We provide hands-on workshops covering welding, injection, and sealant application best practices.
How often should maintenance occur?
We recommend annual inspections with replacement of seals as needed.
Do you supply repair kits?
Yes—resin injection and seal replacement kits are available for emergency repairs.
