If the area under your deck or stairs will collect water or is prone to gathering moisture, an inorganic mulch such as gravel, crushed rocks or river rocks is best. Gravel is a good material to place under outdoor structures, because it allows water to drain and doesn’t decompose.Also Know, do you need to seal the underside of a deck? It is not necessary to stain the underside of your deck for protection from the elements, especially if you use pressure-treated wood, which helps keep wood-boring insects out. Also Know, how do you put drainage under a deck? To provide drainage, the panels should slope toward the outside edge of the deck about 1/4 in. per foot. If the span under your deck is 12 ft., for example, the purlin at the outer end of the deck should be 3 in. lower than the purlin along the house (12 x 1/4 = 3).Can you caulk between deck boards?Don’t be tempted to fill the unsightly gaps in your porch floor with caulk or wood filler.

Should the size of the gap change, refill it with new rope.
