Coastal construction projects have long been troubled by many stubborn wall problems caused by high humidity, heavy rainfall and salt spray corrosion. Ordinary wall materials often face serious issues such as water seepage, wall hollowing, steel bar rusting and mold growth within 3 to 5 years after completion. EPS Cement Sandwich Wall Panel has been proven to be a perfect solution to these coastal pain points after years of practical application in thousands of seaside projects.
The surface layer of EPS Cement Sandwich Wall Panel is made of special high-density anti-seepage cement composite with added anti-corrosion additives. Its water absorption rate is controlled below 3%, which is 10 times lower than that of ordinary concrete blocks. Even if the wall is continuously washed by sea wind carrying salt spray for decades, the salt moisture can hardly penetrate into the interior of the panel. This effectively prevents the hidden danger of steel bar rusting inside the wall structure, which is a very common problem that greatly shortens the service life of coastal buildings.
Many seaside resort projects in tropical rainy areas have reported that after using EPS Cement Sandwich Wall Panel as exterior walls, the previous annual maintenance work of repairing water seepage spots and repainting moldy walls has been completely eliminated. Even in the rainy season that lasts for 6 months every year, the interior wall surface still stays dry and smooth. The wallpaper and paint on the wall will no longer blister and peel off after a few years of use.
For port facilities, seaside warehouses and marine industrial parks that have higher anti-corrosion requirements, this wall panel shows even more prominent advantages. It will not be eroded by salt fog, chemical vapor and humid air like metal wall panels, and it will not breed mold and degrade like wooden wall materials. The design service life of the wall system can easily reach more than 50 years, which greatly reduces the long-term maintenance cost of these coastal facilities.
