Most people have heard that "good fences make great neighbors." Exactly the same is often said for retaining walls. A superb retaining wall allows adjacent properties to become safe and functional regardless of substantial variations in elevation. Retaining walls can transform a sloping site which is unsuitable for development, and turn it into one or a lot more level lots which will support buildings, parking places, walkways or recreation locations. On a smaller scale, a wall can make a level parking or turnaround area for a house or "carve out--" a level location suitable to get a patio or walkway.

Retaining Wall Problems Demand Attention
No matter its size, a retaining wall does not ordinarily attract attention till some thing goes incorrect. Most wall problems are more than aesthetic; they indicate structural concerns that could sooner or later result in all or part from the wall to fail. That is why small wall problems should really be addressed as quickly as they develop into apparent.
We most frequently see smaller walls tilting or bowing as soil pressure around the uphill side from the wall becomes too excellent for the wall to hold. Within a masonry wall, cracks are probably to develop in areas where 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 widespread. A poured-concrete wall can crack and bow within a far more random fashion; it may also begin tilting downhill.
Damage
You will discover particular situations when a damaged retaining wall has to be dismantled and rebuilt. By way of example, you can not usually repair damage from rotting railroad-ties within a wood wall. However, quite a few masonry-based walls may be "rescued" instead of demolished when damage occurs.
Retaining wall damage is extremely similar to the damage that could take place to foundation walls. For this reason, foundation repair contractors possess the training and materials to repair and reinforce smaller sized walls. This kind of specialty contractor is normally the very best choice for little wall fixes.
Helical Repairs
Foundation repair contractors often use helical anchors, also called "tiebacks," to repair a retaining wall that has begun to crack and/or tilt. These steel anchors are made to work like giant screws.
First, a hole must be made in the retaining wall to provide clearance for the anchor. Then helical-shaped plates around the shaft of the anchor pull it in to the soil behind the retaining wall because the anchor is turned. By measuring the hydraulic pressure required to turn the anchor, technicians can determine when an anchor is deep enough to exert adequate bracing force on the retaining wall. Immediately after a steel plate is installed over the end of your anchor that protrudes through the wall, a large-diameter nut might be tightened on the anchor shaft to exert claming pressure around the wall.
Helical anchors are not the only weapon inside a contractor's wall repair arsenal. It may be essential to install curtain drains above the wall to ensure that water can be directed away from the wall. A partial or full excavation in the wall might require to be completed in badly damaged areas. Producing repairs sooner instead of later may be the best solution to prevent the more costly repairs which are essential following greater damage happens.
