Tested and certified Geodomes. POLIDOMES marquees are made of a series of interlocking triangles. Structural load is spread across the structure, making Geodomes especially strong. To us, the importance of safety cannot be overstated. Our dome tents are able to withstand the elements, including high winds and heavy snow, and may be constructed on any terrain, making them a great fit for prolonged use. The materials used must be carefully selected, and the project perfectly carried out. All Geo domes must adhere to the applicable building codes and fire regulations. Large and small tents must be covered in very good quality, long-life covers made of heavy duty, professional-grade three- layer, UV-shielding, flame-retardant material. As a company we also guarantee that all of our structures are TÜV Rheinland Germany certified, proving the high safety standards of POLIDOMES products.
