Around six feet underground, the common Vancouver drain tile is concealed beneath a couple of feet of crushed rock. The perforations along the surface enable water to get in the drain tile; most people recognize enough just how the system works. But what is the gravel for? People have been questioning about it.
Tim Carter of AskTheBuilder.com, in an interview with Waterproof Magazine, mentioned that a common drain tile installment mistake includes the failure to have a layer of crushed rock put in the mechanism. A Vancouver drain tile veiled under heavy soil wouldn't be as powerful in drawing water and moisture away from the foundation of the home. Carter said that the more gravel you place in the drain tile system, the greater. Here's a great examination of just how gravel can help in such endeavor.
Take two glasses, fill one with earth and dirt, and the other with gravel, and put an equal amount of water on both glasses. The soil will maintain more water than the crushed rock, given the fact that earth and dirt is more compact than a lot of loose rocks. With the glass filled with gravel, you may see some quantity of water pooling the rocks.
Crushed rock isn't really good at maintaining water and wetness, due in no small part to the loose density and drifting accumulation of the rocks. When water seeps close to the foundation, the gravel will draw the water far from it and lead it to the drain tile below. It's a simple and economical option that needs a lot of small, loose rocks that you can get virtually anywhere.
But with loose rocks also come the threat of crushed rock clogged in the pipelines. In this situation, Carter advises covering the gravel with either tar paper or six inches of straw. The last thing you wish to happen to your straightforward Vancouver drainage mechanism is for the drain tile's perforations to become clogged. Carter said that most drain tile systems do not have this layer to cut expenses.
