One of the biggest issues in offsite construction is moisture and leaks. Wesco offers a supply of sealants, caulks and adhesives to help solve those issues. In modular factories and offsite construction facilities, contractors need consist products to complete their job. It’s important that enough of the product is available when needed for that just-in-time inventory. Subfloor and drywall adhesives are also products that consumers may not see, but are used in great supply with factories.
