Waterproof Mortar Construction Technology
Corrugated Metal Roof Base
1、Prepare waterproof mortar
Waterproof mortar: water reference ratio of 10kg: 2.273kg, and add 0.5% 108 glue, the specific use should be adjusted according to the construction environment and temperature. Use power tools to stir for 3-5 minutes to ensure smooth mixing.
2、Non-woven paste base
Paste non-woven fabric on the raised zigzag corrugated, then paste prepared waterproof mortar on it.
3、Spray waterproof mortar
After the geotextile to be pasted is dry, spray it twice with the construction method of real stone paint. Overall coating thickness 0.8-1.0mm. The comprehensive dosage is about 3.2Kg of waterproof mortar per square meter.
4、Maintenance
After the surface is dry, spray water or water maintenance every 2-3 hours, always keep the surface wet, continuous maintenance for 3 days.
u Concrete Roof Base
1、Grassroots cleaning
Clean up garbage and other debris to ensure that there is no water, oil stains or floating dust.
2、Wet surface with water
Wet the concrete roof base by spraying or spraying water to prevent the absorption of moisture in the mortar of the surface layer. The qualification criteria are: keep the surface moist but no standing water .
3、Prepare waterproof mortar
Waterproof mortar: water reference ratio is: 10kg: 2.727kg, the specific use should be appropriate to adjust the ratio according to the construction environment and temperature. Use electric tools to stir for 3-5 minutes to ensure smooth mixing.
4、Scrape and paint in two times
The first brush is 0.8mm-1.0mm thick. The second brush is 0.5-0.8mm thick, second brush should apply before the first surface is dry. The comprehensive dosage, the use of waterproof mortar per square meter is about 2.5-2.8Kg.
5、Maintenance
After the surface is dry, spray water or water maintenance every 2-3 hours, always keep the surface wet, continuous maintenance for 3 days.
Water Retention Agent Construction Technology
① Land leveling
Planting: Determine the size and depth of the pit according to the size of the seedling.
② Mix
Mix the seeds and water retention agent evenly.
③ Seeding
Planting: Use 20g-200g water-retaining agent for each tree pit, determine the amount according to the size of the tree, mix it with soil (sand) evenly and fill it into the tree pit.
Planting grass, vegetables and other crops: the reference amount of 15kg-50kg/ mu, according to the specific planting crops to determine. After mixing the water-retaining agent and seeds evenly, scatter them into the soil (sand) and cover the surface with soil (sand).
After seeding, spray water until water retention agent saturated.
④ Growth
Plant growth with water retention agent.
