The demand for thatch mulch

1, select the appropriate material for the cover. Choose safe and fire-proof plates to ensure that the plates will not have adverse effects on the goods, and the cost is low. Not suitable for damage, can be reused without damage or mildew.

2. The thatch cover is very strong. Each piece of material should be firmly fixed. If necessary, a rope or net should be tied outside the board to ensure that the board will not be blown away by the wind.

3. The joint at the top must have a certain depth and cannot be covered by wind or leave gaps. The top must be tight and flat without wrinkles or dents to prevent water accumulation.

4. The bottom of the pile shall be flush with the pile, and shall not be pulled or mopped empty, and shall be firmly tied to the outside of the pile or the ground of the pile. The gasket material should not be exposed outside the pile to prevent rainwater from infiltrating into the pile.

5. When the old tarpaulin is used or there is enough rain, a layer of tarpaulin should be covered on the pile top or pipeline to ensure that the rain will not penetrate.
