What are the main points of waterproof layer construction of linoleum roof?

1) Flexible waterproof roofs are generally suitable for flat roofs of various houses. Because the slope of the flexible waterproof layer made of petroleum asphalt material is relatively small, in order to prevent asphalt from flowing when heated, the slope of 2%~3% should be adopted. 2) The construction of flexible waterproof roof first requires that the concrete or mortar layer at the grass-roots level is dry (except wet paste). The base of waterproof layer is firmly bonded, and even damaged by bubbles generated by hot water evaporation. The waterproof layer has linoleum lap joint at vertical joints such as linoleum wall. Bitumen must be poured to prevent the gap from wind and staggered joints when it meets water. 3) The main advantages of flexible waterproof roof are relatively stable adaptability to building foundation settlement, house vibration or temperature influence, and relatively stable water leakage quality. The disadvantage is that the construction is complicated and the existing water leakage maintenance is troublesome.

Matters needing attention

Roof waterproofing is a weak link in building construction. Flexible waterproof roofs have developed rapidly, including traditional linoleum asphalt roofs, new plastered lime emulsified asphalt roofs, emulsified asphalt-lined glass felt roofs, architectural paint roofs, plastic ointment-coated roofs and clay emulsified asphalt roofs. Note: 1, a typical flexible waterproof roof is composed of a protective surface layer of thermal insulation material and a reinforced linoleum coating on the bottom layer; 2. Coal tar pitch is selected as the main asphalt; 3, heating three thermoplastic materials into liquid and cooling them into solid; 4, choose flexible waterproof roof and install the same type of roof.

material processing

1. Protective materials are damaged and stolen. 2. Store cardboard, thermal insulation materials, rollers or asphalt impregnated cardboard cement containers to raise the platform. 3. It is recommended to store materials in sealed containers, such as buildings or transport containers. 4. There are no available buildings or open-air buildings that need to be protected with waterproof tarpaulins or their solid protective device materials. 5. The sunlight reacts strongly. 6. Storing the packaged asphalt will pollute the asphalt flow. Dry storage of roofing waterproof materials. 8. Because asphalt contains moisture in storage, it is easy for roofing technicians to generate foam when heating. 9. Store the drum cleanly and raise the platform to prevent the end of the drum from being damaged.
