Wet concrete slurry contains calcium hydroxide with an extreme alkaline pH exceeding 12.5, causing severe chemical burns and deep skin ulcerations if slurry seeps into work shoes. GUANGHE's Concrete & Masonry S7S Boots utilize fully sealed internal waterproof bootie membranes and high gusseted bellows tongues that prevent liquid slurry ingress up to the collar. Built with alkali-resistant dual-density PU/PU soles and heavy-duty 200J steel toe caps, these boots withstand abrasive gravel aggregate and caustic wet cement paste while ensuring feet remain completely dry and uninjured.
