The Pros and Cons of Concrete BlocksĬoncrete blocks provide a simple way to put a foundation under your shed.

(See this example.)Īnother possibility is to build your patio using permeable or porous concrete pavers, which allow water to percolate through the patio into the ground below. A more attractive option is to place the patio slab in sections with strips of decorative gravel or groundcover in between. If your landscape prevents you from pitching the patio to allow for natural water runoff, your concrete contractor can install an in-slab drainage system with gravel-filled channels to carry the water away. The best way to prevent patio drainage problems is to plan for them when the slab is installed. How do I prevent poor drainage when putting in a new patio? The overlay was placed in sections separated by integrally colored borders to add decorative interest and to eliminate the need for sawcuts. On this project, the pitch of the patio was corrected by installing an overlay ranging from 4 inches down to under an inch. They are installed flush with the surrounding patio so they won't be a triping hazard.Ī more radical yet effective solution is to reestablish the pitch of the patio slab by installing a cement-based overlay. These drains are typically just a few inches wide and allow water to pass through, but keep out debris. Instead of gravel, you can also have a trench or channel drain made of metal installed. Where the water tends to collect, cut out a sloping channel in the concrete to direct the water away, filling it with decorative stone or gravel. If you have an existing concrete patio that does not have a drainage system, it’s not too late to install one. PATIO DRAINAGE SYSTEMS FOR NEW AND OLD CONCRETE What are the solutions for existing patios? The pitch of a patio can be corrected using an overlay, as was done on this project. Installing a gutter system and redirecting downspouts away from the patio will usually correct the problem. If rainwater is flowing directly onto your patio from a roof overhang or downspout, the water will pool in that area quickly. Over time debris can collect in the drainage channels and cause a blockage. If your patio used to drain well after a heavy rain, but now seems to collect water, you may have a clogged drainage system. If your patio is completely flat and has low spots where the water collects, it needs to be angled or sloped slightly so the water will run off the surface, much like a roof gutter is sloped to direct water to the downspout.įind concrete patio contractors near me who can assess and fix my drainage problems.
