What is the best way to prepare the foundation before laying the Yunnan EVA waterproof membrane?
Release date:
2021-01-08
Yunnan Linyi EVA Waterproof Board The leak-proof performance is closely tied to the construction process during installation, so when laying… Yunnan Linyi EVA Waterproof Board Previously, how did we decide on handling the foundation laying?
1. Cleaning
The flooring material requires a solid, smooth, and level substrate—no unevenness, cracks, or protruding sharp objects like debris, wire, or stones. Therefore, before installation, the surface must be carefully leveled and thoroughly cleared of any sharp or foreign materials.
2. Lay down the protective layer
If laying down turf or similar surfaces Yunnan Linyi EVA Waterproof Board , clear the tree roots and apply herbicide to eliminate weeds. Yunnan Linyi EVA Waterproof Board The contact surface should be covered with a protective layer of fine-grained sand or clay, with the thickness of the protective layer being at least 30 cm.
Next up is the laying of Yunnan Linyi EVA Waterproof Board Alright, everyone is now proceeding. Yunnan Linyi EVA Waterproof Board When carrying out construction, it's crucial to pay attention to certain details—otherwise, problems are bound to arise.
First, while proceeding Yunnan Linyi EVA Waterproof Board When welding between them, be sure to pay attention. Yunnan Linyi EVA Waterproof Board There should be no moisture, oil stains, or dust between the materials. Be sure to leave a gap of 6 to 8 centimeters at the seams, which can then be overlapped using single-layer PE material—this approach ensures exceptional waterproofing at the joint.
Second, when laying the material, be sure not to pull the Yunnan Linyi EVA waterproof membrane too tightly. Instead, leave some room for expansion and contraction to allow it to accommodate the deformation of the substrate. This will help prevent Yunnan Linyi EVA Waterproof Board It eventually cracked, causing it to leak.
Third, when laying it down, make sure to use treated soil—don’t allow the concrete to come into direct contact. Yunnan Linyi EVA Waterproof Board , preventing alkaline substances in concrete from causing corrosion Yunnan Linyi EVA Waterproof Board 。
Fourth, it welds well. Yunnan Linyi EVA Waterproof Board A layer of sand or clay is laid on top to protect it. So far, the process is basically complete. Yunnan Linyi EVA Waterproof Board The entire construction process.
