Liquid Jacket is our very own brand of waterproofing & damp proofing products. From humble beginnings, starting out as a mastic contractor in 1971 known nationwide as County Mastics, progressing into material distribution 10 years later with a sister company (which is our business County Construction Chemicals Ltd. ) then evolving to internet sales in 2012 with our e-shop Sealants Online, we have nearly 50 years of waterproofing experience and thus felt the time was right to use our technical know-how and experience to launch Liquid Jacket as a small selection of specialist waterproofing and damp proofing products.
