FAQ
Frequently asked questions
Short answers to the questions buyers ask most before ordering trenchless point-repair products.
What products does Reliance Trenchless supply?
We supply 11 products in 5 families: instant-lock stainless steel sleeves, internal pipe seals, pipe plugs, repair packers, fiberglass and resin materials, point-repair jacks and mortar sprayer systems. They are made by our manufacturing partners Wenzhou Wantuo, Qingdao Xinya and CNLG.
Can pipes be repaired without digging?
Yes. Our point-repair products are installed from inside the existing pipe through a manhole or access point, so localized defects such as leaking joints, cracks and local damage can be repaired without excavating the street. Whether a repair suits your pipe depends on its diameter, material, condition and the defect, so confirm the selection against the published specifications.
How do I choose the right product size?
Start from the pipe inside diameter, pipe material and the defect or task. Every product page lists dimensions, specifications and brochures, and the pipe size finder on the products page narrows the range. If you are unsure, send us those details with the quantity and we will suggest products for you to confirm.
Are your products CE certified?
EU TEST has issued attestations of conformity for 6 product groups after verifying their technical files against EN standards. These are voluntary technical-file verifications, not Notified Body certificates. Each attestation, its standards and its validity dates are shown in the certificates section of this site.
Do you ship internationally?
Yes. We have supplied customers in 37 countries from Wenzhou, Zhejiang, China. Orders are wrapped, labelled and crated on pallets for export and ship by sea (FCL or LCL), land, air or rail, depending on your destination and timeline.
