What is Dimple mat?
A dimple mat is a sheet of semi-
inflexible plastic (usually high-
thickness polyethylene) that comes 
in a roll. The plastic is the size of an 
egg container, with jutting dimples 
that make the crust really thick — 
between 1/4 inch and 1/2 inch thick 
for the most part.
At the point when a dimple 
mat is put against a 
substantial divider, the 
dimples make the plastic 
stand apart from the divider, 
leaving a free-depleting air 
space between the plastic and 
the substantial. Assuming any 
water arrives at this air space, 
it effectively streams to the 
lower part of the dimple mat.
