2. Most folks have heard that "good fences make good neighbors." Exactly the same could be said for retaining walls. A good retaining wall allows adjacent properties to be safe and functional despite significant differences in elevation. Retaining walls can transform a sloping site that is unsuitable for development, and turn it into one or more level lots that may support buildings, parking areas, walkways or recreation areas. On an inferior scale, a wall can make an even parking or turnaround area for a residence or "carve out--" an even area suitable for a patio or walkway.

4. Retaining Wall Problems Require Attention
5.  
6. No matter its size, a retaining wall doesn't usually attract attention until something goes wrong. Most wall problems tend to be more than aesthetic; they indicate structural conditions that could eventually cause all or portion of the wall to fail. That's why small wall problems should be addressed the moment they become apparent.

8. We most often see smaller walls tilting or bowing as soil pressure on the uphill side of the wall becomes too ideal for the wall to carry. In a masonry wall, cracks will probably develop in areas where in fact the soil pressure is greatest. If the wall is constructed from blocks or CMUs (concrete masonry units), "stair-step" cracking along mortar or joint lines is common. A poured-concrete wall can crack and bow in a far more random fashion; it can also start tilting downhill.

10. Damage
11.  
12. There are certain instances when a damaged retaining wall needs to be dismantled and rebuilt. For instance, you can't usually fix damage from rotting railroad-ties in a wood wall. However, Visit this site -based walls can be "rescued" instead of demolished when damage occurs.

14. Retaining wall damage is quite like the damage that can occur to foundation walls. Because of this, foundation repair contractors have the training and materials to fix and reinforce smaller walls. This sort of specialty contractor is normally the best choice for small wall fixes.

16. Helical Repairs
17.  
18. Foundation repair contractors often utilize helical anchors, also referred to as "tiebacks," to repair a retaining wall which has begun to crack and/or tilt. These steel anchors are made to work like giant screws.
19.  
20. First, a hole should be made in the retaining wall to provide clearance for the anchor. Then helical-shaped plates on the shaft of the anchor pull it in to the soil behind the retaining wall as the anchor is turned. By measuring the hydraulic pressure necessary to turn the anchor, technicians can determine when an anchor is deep enough to exert sufficient bracing force on the retaining wall. After a steel plate is installed over the end of the anchor that protrudes through the wall, a large-diameter nut can be tightened on the anchor shaft to exert claming strain on the wall.
21.  
22. Helical anchors aren't the only weapon in a contractor's wall repair arsenal. It might be essential to install curtain drains above the wall so that water can be directed from the wall. A partial or full excavation of the wall might need to be done in badly damaged areas. Making repairs sooner rather than later is the best means of avoiding the more costly repairs that are necessary after greater damage occurs.
