Foundation Maintenance & Why it Matters

It all starts with understanding foundation maintenance. Before starting the landscaping, understand the role root barriers, moisture barriers and foundation watering play with future gardening.

Root barriers are mechanical guides. They redirect tree roots down and away from hardscapes. This helps prevent costly root damage to your foundation. It also helps preserve the health and beauty of mature trees.

Moisture barriers are vertical layers of plastic buried underground. This helps keep water from getting under the house, causing foundation movement.

Foundation watering helps maintain constant moisture levels in soil under the house.


Start with the Soil

Okay, so we’ve got the nitty-gritty details down. Now let’s get our hands dirty. It starts with the soil around the house. Step one is to slope soil away from the house, helping water drain away from the foundation. If the soil starts level with the rest of the yard, consider building up the area, rather than digging down. If the soil is already slopping away from the house, perfect.

Tip: Often while weeding and planting, the soil is pushed back and forth. Keep an eye on it as you work and push the soil back to maintain the needed slope.


Don’t Forget the Mulch

Select the right mulch. It should help slow evaporation while lettings your plant breath. It should not attract insects. So do you go organic or inorganic? Organic mulches help feed the soil. Grass clippings and leaves decompose back into the dirt. Add clippings as the older ones decompose. Inorganic mulches last longer but do not replenish the soil. These include pebbles, lava rocks, seashells, plastic, and rubber. Both types help maintain moisture levels around the foundation and plants. It comes down to aesthetic preferences. Either type will do the job.
