Potable-water-safe cistern sealing, leak repair and full restoration — sealed to manufacturer specification so it actually lasts.
Almost every Anguilla home relies on a cistern. And almost every Anguilla cistern we inspect has the same problem: it was sealed with the wrong product, applied the wrong way. Asphaltic emulsions, generic pool paints, cheap waterproofing compounds — none of them are rated for potable water storage, and none of them last more than a few years before cracking, peeling, or leaching into the drinking supply.
Premier Roofing & Waterproofing Systems restores cisterns the way the system manufacturers actually specify them. Proper surface prep. Potable-water-rated cementitious or epoxy systems. Multi-coat application with manufacturer-required cure times. Tested for leaks before sign-off. Your cistern doesn't just hold water — it holds the water your family drinks.

If your cistern was sealed with asphaltic material, it was sealed wrong. Asphaltic emulsions are not rated for potable water — they leach hydrocarbons into your drinking supply and break down under sustained submersion within a few years. Yet they're still routinely applied across Anguilla because they're cheap and easy.
The correct systems for cistern waterproofing are NSF-61 certified cementitious membranes (like Henry CM100 with potable-water primers), epoxy linings, or polyurea coatings — all of which require proper surface prep, multi-coat application, and cure-time discipline. They cost more up front, but they last 4-5 times longer and don't poison your water. Read our full cistern restoration guide for the technical breakdown.
