Retaining Wall Repair in Lisbon, IA
Cedar Rapids Retaining Walls repairs, resets, and rebuilds retaining walls in Lisbon, Iowa. We handle block, stone, and timber, correct drainage behind walls that are otherwise sound, and terrace slopes into usable yard. Licensed and insured across Iowa.
Settlers laid Lisbon out in the eighteen fifties and named it after the city in Portugal. It shares the same ridge belt as its neighbor next door, so the older streets carry real grade rather than the flat plat you find closer to the metro. The walls match the town. Many are decades old. Some are dry-laid stone, some are timber on its second life, and some are block that went in long before drainage stone was standard behind a residential wall.
An old wall usually tells you what is wrong with it. Bulging in the middle means the backfill behind that spot is loaded and has nowhere to send water. Separation at a joint means the wall has rotated forward. A course that has dropped means the base under it gave way, and that is a base problem, not a block problem. Efflorescence and white staining means water is moving through the wall, which is a drainage answer.
Our fix opens the back. Out comes the dirt backfill. In goes clean angular stone, a perforated pipe with a fabric sleeve, and filter fabric between the stone and the native soil. The pipe runs on a slight fall and exits at daylight, where the water leaves the hill for good. A pipe that stops inside the backfill is a bathtub with a hose in it.
Where the wall was built with dry-laid stone, we rebuild in stone and keep the look.
