Extreme weather conditions are becoming more and more common in the Netherlands. Prepare well:First, lay a thin plastic sheet on the ground (you can throw this away when you leave).On top, place a thick plastic sheet or tarpaulins (available at hardware stores), and place your mats or other materials on top of it. Make sure that the edges of the tarpaulin or plastic in the (front) tent are bent upright.Shape it into a kind of bowl / tub so that rainwater cannot flow insideIf necessary, roll up a few empty bottles in the edges of the plastic to create a higher edge. Unfortunately, we cannot always prevent inconvenience during extreme downpours. This is often force majeure, as in the Netherlands streets, houses and cellars are flooded during extreme downpours.
